Alzheimer Histology Autofluorescence

Farley et al. (1972) found a herpes-like infection in the haemocytes of moribund American oysters, C. virginica, held in thermal effluent (28-30 C, within the temperature tolerance range of C. virginica) from a power plant in Maine. Mortalities of 52 were attributed to this infection, which was characterized by Feulgen-positive nuclear inclusions in the haemocytes of all moribund specimens (Fig. 20.1). Similar inclusions were found in wild, apparently healthy, oysters at the site of collection (Farley et al., 1972). Non-enveloped virions, 7090 nm in diameter, were found in the nucelus of infected cells. Enveloped particles, 200-250 nm in diameter, occurred in the cytoplasm. Cowdry type A intranuclear inclusion bodies* (Cowdry, 1934), morphological and nucleic acid characteristics resemble those of other herpes-type viruses (Farley, 1978 Francki et al., 1991).

Cercopithecine herpesvirus 6 CeHV6 An

Unassigned species in the subfamily Alphaherpesvirinae. Genome DNA is 52 G+C. Causes a severe, often fatal, exan-thematous disease in captive vervet monkeys. Antibodies to the virus are rare among monkeys in the wild but the infection spreads rapidly when they are brought together in captivity. Sub-clinical infections are common, but in severe cases there are necrotic hemorrhagic lesions in the lungs, intestine, liver and other organs. Other monkeys, mice and rabbits are resistant to infection. Virus replicates with CPE in vervet monkey kidney cell cultures, also in human thyroid, Vero cells and many other cell lines. Produces no pocks on the CAM and does not kill the embryo. The virus is strongly cell-associated. Antigenically very closely related to Human herpesvirus 3. Synonyms Liverpool vervet monkey virus vervet monkey herpesvirus SA12 virus.

Herpesvirus replication generates inclusions in the nucleus

Herpesviruses enter the cell by fusing their envelopes with the plasma membrane, whereon the naked nucleocapsids migrate to nuclear pores, possibly along microtubules (Granzow et al., 1997 Sodeik et al., 1997) reviewed by Smith and Enquist (2002) . Nuclear inclusions housing herpesvirus DNA replication are globular and can occupy the majority of the nucleus (de Bruyn Kops and Knipe, 1988 Randall and Dinwoodie, 1986 Taylor et al., 2003). They are identified through the presence of the viral DNA-binding protein encoded by the UL29 gene, which is also known as infected cell protein 8 (ICP8). A minimum set of seven genes, UL5, UL8, UL9, UL29, UL30, UL42, and UL52, has been identified as necessary for viral DNA replication (Challberg, 1991). A plasmid trans-fection system has shown in vitro these can form globular nuclear compartments that are sites of 5-bromo-2'-deoxyuridine (BrdU) incorporation and visually are similar to those formed during infection (Lukonis and Weller, 1997 Zhong and...

Human Herpes Virus8Related Tumors Human Herpes Virus8

With the HIV epidemic in the early 1980s, homosexual men were found to have a 20-fold higher risk than other risk groups in developing Kaposi's sarcoma (KS).The uneven distribution among HIV risk groups lead to the search for an infectious transmissible agent, which eventually led to the discovery of the KS herpes virus or human herpes virus-8 in 1994. HHV-8, a gammaherpesvirus2 (genus Rhadinovirus) is a large (165 kb) double-stranded DNA virus that has an extensive group of regulatory genes obtained from the host genome.142 The DNA sequences of HHV-8 on discovery were found to be homologous to, yet distinct from genes of gamma-herpesvirinae, herpesvirus saimiri, and EBV.143

Digital Herpes Simplex

Recurrent herpes simplex despite being rarely diagnosed is not infrequent. Any recurrent blistering process around a finger nail, particularly when accompanied by early lymphangitis and radiating pain, should prompt a cytological examination. The blister roof is opened and a Tzanck smear taken for microscopic investigation as well as for virus culture or molecular biological tests. Early blisters with clear watery contents exhibit mainly keratinocytes, some of which are giant and multinucleated. Securing the blister roof for histological sections may be necessary to rule out an early bullous impetigo (run-around). Herpes zoster infrequently extends to the digits. Tzanck tests demonstrate an essentially similar picture to that of herpes simplex.

Herpesviridae Neoplasms

Herpes Virus Salmon

Three herpesviruses of salmonids have been reported to be oncogenic. Oncorhynchus masou virus (OMV) causes cutaneous carcinoma (Fig. 3.7) in coho salmon, chum salmon (Oncorhynchus keta), cherry salmon (Oncorhynchus masou) and rainbow trout (Kimura et al., 1981 Yoshimizu et al., 1987, 1988). This virus was originally isolated from apparently healthy cherry salmon, (Kimura et al., 1981). Yamame tumour virus (YTV) was first isolated from a neoplasm on the jaw of a cherry salmon (Sano et al., 1983), and coho salmon tumour virus (CSTV) was isolated from neoplasms on coho salmon (Sano, 1988). These three viruses are serologically related (Hedrick et al., 1987 Sano, 1988), and OMV and YTV are strains of Herpesvirus salmonis Type 2 (Eaton et al., 1991b). There is strong evidence that both OMV (Yoshimizu et al., 1987) and YTV (Sano et al., 1983) are oncogenic virus was re-isolated from neoplasms of experimentally infected fish. Morrison et al., (1996) observed virions with the appearance of...

Nuclear inclusions also form as sites of herpesvirus assembly The assemblon

A second prominent nuclear inclusion induced by herpesvirus infection is the assemblon (Ward et al., 1996b). This is the site where capsid proteins accumulate and assemble into nucleocapsids (Fig. 8B). The assembly of herpesvirus nucleocapsids has been researched in great detail at the ultrastructural level facilitated by a cell-free system for reconstituting the particles (Heymann et al., 2003 Newcomb et al., 1994,1996). The mature herpesvirus capsid is icosahedral with a T 16 symmetry and is composed of 150 hexons and 11 pentons of the major capsid protein UL19. The place of the remaining penton is taken by a 12-mer of the portal protein UL6, which by analogy with bacteriophage may be the site of genome entry. Nucleocapsids mature from fragile procapsids, through B capsids that lack DNA and contain the internal scaffold protein UL26.5, to C capsids that contain the viral genome. The relationship between assemblons and sites of viral DNA replication has been a topic of some...

It may occur inside the cell (e.g. picornaviruses, reoviruses, papova-viruses, adenoviruses, herpesviruses and poxviruses), in which case cell lysis is needed for egress. Alternatively, maturation may be linked with egress from the cell as seen with most enveloped viruses (e.g. negative-strand viruses, togaviruses and retroviruses).

The animal was one of a number with a fatal generalized disease taken from Kawan Island in Auckland Bay, New Zealand. The culture developed foci of CPE which extended rapidly. Experimental infection of Parma wallabies causes a severe generalized disease with lesions in lungs and liver. Antibodies are found in a wide range of macropods (kangaroos and wallabies) from different parts of Australia. No CPE in bovine, mouse or hamster cells. The DNA is distinct from other herpesviruses, G+C 53 . macropodid herpesvirus 1 (MaHV-1) Synonym Parma wallaby herpesvirus.

Cytoplasmic inclusions form during late stages of herpesvirus tegumentation The cytoplasmic assembly compartment

The tegument layer of alphaherpesviruses is composed of at least 15 different proteins (Mettenleiter, 2002). US11, UL17, UL47, UL48, and UL49 are components of the tegument, and all are localized to the nucleus (if not exclusively) during the productive life cycle of the virus (Fuchs et al., 2002 Hutchinson et al., 2002 Kopp et al., 2002 Roller and Roizman, 1992 Taus et al., 1998). UL48 may play a role in egress from the nucleus, though this has not been unequivocally established (Mossman et al., 2000). Therefore, it is likely that some tegument proteins are acquired in or during viral egress from the nuclear inclusions. Recently, cytoplasmic aggresome-like structures have been described in cells infected with HHV-2.1 These contain the major capsid protein, tegument proteins, envelope glycoproteins, and markers for the Golgi complex (Nozawa et al., 2004). The latter finding is particularly interesting because herpesvirus envelopment involves membranes from the TGN (Mettenleiter et...

Nuclear inclusions associated with herpesvirus replication are linked to ND10PML Bodies

For Roblox Hats

Replication compartments are formed from a number of different discrete foci that are induced early in infection and whose interrelatedness is not fully understood. The initial stages of productive herpesvirus infection are, however, intimately linked with nuclear structures called ND10 bodies (illustrated in Fig. 8) Ishov and Maul (1996), Maul et al. (1996), review by Borden (2002) . Live cell studies have shown that the immediate early regulatory protein ICP4, which binds viral DNA, forms discrete foci as early as 30-min postinfection (Fig. 8A). These initially appear close to the nuclear envelope, possibly at sites where the genome first enters the nucleus following capsid disassembly at nuclear pores (Everett and Murray, 2005), and are then seen throughout the nucleus (Everett et al., 2004). ICP4 foci are seen juxtaposed to the ND10 marker promyelocytic leukemia protein (PML) some 60-min later. The early and late regulatory protein ICP27 is recruited to ICP4 foci 2-h postinfection...


Herpesviruses are large dsDNA viruses with genomes ranging in size from 120 to 250 kbp. Herpesvirus genes are expressed in a regulated cascade starting with the immediate early a genes, then early p genes, and finally two subsets of late g genes, g1 and g2. Complete herpesvirus particles have four main layers, the core containing DNA, an icosahedral capsid, a poorly defined layer of protein called tegument, and finally the viral envelope containing several glycoproteins. Genome synthesis and packaging and capsid assembly occur in inclusions in the nucleus. Nucleocapsids then obtain tegument in either the nucleus or the cytoplasm, or both, and the viral envelope is acquired exclusively in the cytoplasm see Mettenleiter (2002) and Mettenleiter et al. (2006) for more thorough analysis . The transfer of virus from the nucleus to the cytoplasm and acquisition of tegument appears well defined for human herpesvirus 6 (HHV-6) (Roffman et al., 1990) but is controversial for the...

Herpes simplex

Herpes Finger

Distal digital herpes simplex infection may affect the terminal phalanx as a primary herpetic 'whitlow' or start as an acute, intensely painful paronychia (Figures 5.37, 5.38). It is relatively common in dental staff, anaesthetists and those involved with the care of the mouth and upper respiratory tract in unconscious patients. Recurrent forms are generally less severe and have a milder clinical course than the initial infection. It is important to exclude primary or recurrent herpes simplex infection in the differential diagnosis of every vesiculopustular finger infection. The typical appearance of the lesions with disproportionately severe pain, the absence of pus in the confluent, multiloculated, Primary herpes simplex herpetic 'whitlow'. Primary herpes simplex herpetic 'whitlow'.

Herpes neuropathy

Herpes virus remains in a latent state in the dorsal root ganglion or trigeminal ganglion. Motor signs are infrequent (herpes zoster), and are caused by radiculopathy. Motor impairment occurs in the corresponding myotome to the sensory distribution. Long standing radicular pain that resembles diabetic neuropathy or infiltrative radiculopathy may be caused by herpes reactivation without the distinctive rash (zoster sine herpete). Cranial nerve palsies are also common, include oculomotor and facial nerve palsies, and optic neuritis or vestibulocochlear impairment (Ramsay-Hunt syndrome). Herpes simplex or Herpes zoster (chicken pox) infection can come out of latency in a sensory ganglion. Herpes zoster occurs frequently in HIV patients and patients recovering from chemotherapy. The virus migrates down the sensory nerve fibers to the skin, causing tissue damage and inflammation. The pain syndromes associated with post-herpetic neuralgia may result from altered CNS pain pathways, aberrant...

Herpes zoster

Varicella zoster virus (VZV) causes both chickenpox, the primary illness, and herpes zoster, which follows reactivation of the virus in the nerve ganglia. In zoster, pain, fever, and malaise may occur before erythematous papules develop in the area of the affected dermatome most commonly in the thoracic area. Vesicles develop over several days, crusting over as they resolve. Secondary bacterial infection is common. Some patients develop episodes of pain in the affected area postherpetic neuralgia after clearance of the rash. Skin lesions and nasopharyngeal secretions can transmit chickenpox.

Herpes Simplex Virus

Linear esophageal ulcers caused by herpes simplex virus (HSV) and Candida. Infection with HSV-1 and -2 leads to stomatitis and esophagitis post-transplantation without acyclovir prophylaxis. Additionally, paronychia, corneal ulcers, encephalitis, genital lesions, disseminated involvement of the gastrointestinal tract, pancreas, and liver, and interstitial nephritis has been seen. HSV-6 causes exanthem subitum in children, mononucleosis, and hepatitis. There has been some evidence that reactivation infections may be associated with rejection in transplant recipients. Both reactivation and reinfection may occur. HSV-8 is associated with Kaposi's sarcoma. Prevention of these infections has been achieved using prophylactic acyclovir following transplantation. If clinical symptoms occur from HSV, they usually are treated with acyclovir adjusted for renal function. 94 of adults have evidence of a prior VZV infection.

Epsteinbarr Virusrelated Tumors Epstein Barr Virus

Epstein-Barr virus (EBV), a human herpesvirus of the Lymphocrytovirus genus,1 was first discovered by electron microscopy in Burkitt's lymphoma (BL) cells in 1964.2 Subsequently, the complete (172,282 bp) nucleotide sequence of EBV (B95-8 strain) was established in 1984.3 Like all herpesviruses, EBV has latent and productive (lytic) phases in its life cycle, the former maintaining the virus long term in its host and the latter potentiating virus production and spread. Using a distinct set of latent genes EBV has oncogenic capability and the ability to induce immortalization of B lymphocytes in vitro.4

Treatment And Survival Of Ks

The discovery of HHV-8 in all forms of KS has raised the possibility of using antiviral agents to target this virus. HIV-infected individuals that used foscarnet instead of ganciclovir to treat cytomegalovirus disease had a considerably longer time of their existing KS progressing to a more severe form.204 In another trial, the use of ganciclovir for treatment of cytomegalovirus disease reduced the risk of developing KS.205 A pilot study using cidofovir for the treatment of AIDS-associated and classic KS showed no effect on disease progression, no decrease in viral load of HHV-8 among seven patients, and no change in expression of early lytic and latent gene expressions from cutaneous KS lesions. Only one of seven patients demonstrated decreased production of a late lytic gene.206

Aidsassociated Nonhodgkins Lymphoma

22 of 24 patients with a progression free survival of 23 months. These patients had favorable prognostic factors (median CD4+ lymphocyte count of 233 mm3 ml).119 Enhanced toxicity of rituximab and CHOP chemotherapy was recently noted in a large multicenter trial conducted by the AMC.60 The addition of rituximab to standard-dose CHOP as compared to CHOP alone led to increased infectious complications and deaths attributable to sepsis. It is possible that delayed recovery of humoral immunity could contribute to this increased risk of life-threatening bacterial infections in HIV-infected patients.There have been several reports on the feasibility and efficacy of high-dose chemotherapy and autologous stem cell transplant for ARL.69,95 It is reasonable to assume that patients with well-controlled HIV and good performance status should be considered candidates for this therapy. Newer approaches that may benefit patients with ARL include EBV specific cytotoxic T cells and agents that...

Nucleotide Reverse Transcriptase Inhibitors Tenofovir Disoproxil Fumerate Viread

Tenofovir is a nucleotide analog reverse transcriptase inhibitor. The best-known nucleotide analogues are the antivirals, ade-fovir (Hepsera) and cidofovir (Vistide), used for the treatment of hepatitis B and cytomegalovirus infections. Adefovir was discontinued as an HIV therapy due to proximal renal tubular dysfunction. See Fig. 2.13 for names, structure, and approved uses of tenofovir. It is FDA-approved for the treatment of HIV infection in combination with other anti-HIV therapies. The recommended dosage for tenofovir is 300 mg taken orally once each day. The lower number of dosages per day increases the probability that the patient will exercise medication compliance (167). The medication is in tablet form and may be taken with or without food. If patients have a decreased kidney function, the medication may need to be taken less frequently. Tenofovir resistance occurs and may be

Hemolytic anemia Reported rarely

Concomitant acy-clovir nearly doubles the risk of indinavir-associated renal complications. In one study, events occurred in nearly 26 of the cases, many of which could have been avoided. Careful monitoring should be done if acyclovir is prescribed with indinavir (265).


AIDS malignancies have been recognized as a major complication of the HIV disease course, and the high mortality rate in AIDS patients is in part due to this complication. A number of factors have been implicated to be playing a role in the increase incidence of malignancies in AIDS patients. These factors include immunosuppression and a deficient immune surveillance by T cells in eliminating the transformed cells viral cofactors such as EBV and KSHV have also been associated with malignant transformation of the infected cells. The prognosis of ARL in HIV-infected individuals was extremely poor prior to the HAART era, but the advent of HAART, there was a dramatic improvement in the prognosis of ARL in these patients.The survival rate has improved, especially for those ARL that were found to be associated with herpesviruses such as EBV and KSHV There were a substantial decrease in the number of cases of KS and NHL, in association with HAART, and the decrease in incidence appear to be...

In a clinical study, 24 patients with dendritic corneal epithelial ulcers were treated by minimal wiping debridement, 12 then receiving the drug topically as eye ointment, the others being given a placebo. Seven of the placebo patients showed recurrence of herpetic corneal lesions within a week. There was no recurrence in the patients receiving...

S23dihydroxypropyladenine An

Form, araATP, by cellular kinases it inhibits viral DNA synthesis at lower concentrations than are required to inhibit host cell DNA synthesis, by inhibiting the viral DNA polymerase. It neither directly inactivates virus nor prevents attachment. In the body it is speedily converted to the hypoxanthine, with a decline to less than 50 of the original antiviral activity. It is active against herpesvirus and poxvirus less so against adenovirus and papovavirus. The drug has no action against RNA viruses. Although acyclovir is the drug of choice for treatment of herpes simplex or varicella-zoster infections, adenine arabinoside appears useful for treatment of acyclovir-resistant mutant viruses. Synonyms vidarabine araA vira-A.

Adenoassociated virus 16 AAV16

Replication is dependent upon the presence of a helper adenovirus for complete virus production, but infectious DNA and antigens demonstrable by immuno-fluorescence are made in the presence of a helper herpes-type virus. Can also establish a latent infection in the absence of a helper virus. Replicates in cells which support adenovirus replication to a higher titer than the adenovirus whose replication may be depressed. Not genetically related to adenovirus. Mature virus particles contain either positive or negative strands of DNA which are complementary, and after extraction anneal to form double-stranded DNA. There are a number of serotypes. The type species is type 2. Types 1, 2, 3, 4 and 5 are primate adeno-associated viruses. There are also bovine, avian, canine, ovine and equine types. Antibodies can be found in human sera, but none of these viruses is known to be pathogenic. The use of AAV as a vector for potential gene therapy in a clinical...

Conjunctivitis And Dacryocystitis Conjunctivitis

Conjunctivitis in the newborn infant usually is due to chemical and mechanical irritation caused by the instillation of silver nitrate drops or ointment into the eye in order to prevent gonorrheal ophthalmia. Chemical conjunctivitis differs from infective forms in that it becomes apparent almost immediately after the instillation. The most common causes of infectious conjunctivitis in descending order of frequency are Chlamydia trachomatis, Neisseria gonorrhoeae, Staphylococcus spp., inclusion conjunctivitis caused by groups A and B Streptococcus, Enterococcus spp., Streptococcus pneumoniae, Haemophilus influenzae, Pseudomonas aeruginosa, E. coli, Moraxella catarrhalis, Neisseria meningitidis, Corynebacterium diphtheriae, herpes simplex virus, echoviruses, and Mycoplasma hominis (18). Clostridia and peptostreptococci were also implicated as probable causes of neonatal conjunctivitis (19).

Amphotropic murine type C virus A strain

A cloning-amplifying vector consisting of repeat units of herpes simplex virus (HSV) defective genomes. Can replicate in the presence of standard HSV helper virus. Co-transfection of cells with helper virus DNA and amplicon generates concatameric defective genomes composed of multiple reiterations of the repeats. Foreign DNA sequences can be introduced to form concatameric chimeric defective genomes that are efficiently packaged and can be stably propagated in serially passaged virus stocks. 2. The product nucleic acid obtained from a polymerase chain reaction.

Gene Transfer Vectors

There are two main types of gene delivery vectors viral and non-viral vectors. Retroviruses lentiviruses, recombinant herpes simplex virus, adeno-viruses, and adeno-associated viruses are the most common viral vectors that have been used for the delivery of genes into the CNS. More recently, there have been studies also about the possible use of Baculoviruses (Lehtolainen, 2002, Tani, 2003) Semliki Forest viruses (SFV) (Lundstrom, 2001), Sindbis virus (Ehrengruber, 2002) and recombinant Simian virus-40 (SV40) (Cordelier, 2003) for gene therapy in the brain.

Angiogenesis In Kaposis Sarcoma An Example Of Combined Action Between Angiogenic And Inflammatory Inducers

Kaposi's sarcoma (KS) is a multicentric, highly vascularized neoplasm, probably arising from a monoclonal population of circulating progenitor cells that home to multiple visceral and cutaneous sites (97,98). KS incidence is greatly enhanced in AIDS patients, being detected in about 20 of the affected individuals, who develop a particularly aggressive form (99). Four principal features of KS include the presence of spindle cells, which represent the core of the lesion an aberrant proliferation of endothelial cells with prominent angiogenesis the presence of infiltrating mononuclear cells and increased vascular permeability. The histogenesis of spindle cells is still debated, but recent data, showing the co-expression of endothelial and macrophage antigens, permit speculation that the origin of spindle cells is in a precursor that differentiates in normal tissue in the sinus-lining cells of spleen and lymph nodes (100). The molecular mechanisms regulating the differentiation of a...

Genital Ulcer Diseases

Most sexually transmitted genital ulcers in the UK are caused by Herpes simplex virus (HPA, 2005). Treponema pallidum is another common cause. Dark-ground microscopy, serological testing for syphilis and Herpes simplex culture can be performed to aid diagnosis. Nucleic acid amplification tests are also available for both organisms. Other sexually transmitted infective causes such as lymphogranuloma venereum, Haemophilus ducreyi and donovanosis should be considered, and a good travel history of both the patient and their partners is helpful. Other non-infective causes of genital ulcer disease include Behcet's disease and Crohn's disease. HERPES SIMPLEX VIRUS Herpes simplex virus typically presents as multiple painful vesicles or pustules, which break down to form erosive ulcers. These are generally painful and may coalesce to form larger areas of painful ulceration. True primary episodes are generally more severe than subsequent episodes, and are often associated with systemic...

Human endogenous retroviruses HERV

Human herpesvirus 1 (HHV-1) Type species of the genus Simplexvirus in the subfamily Alphaherpesvirinae. The genome DNA has been completely sequenced for the 17syn+ strain, and consists of about 150kb with a G+C of 67 . The DNA is infectious and has two components, L and S, each of which is bracketed by internal repeats. Primary infection is common in young children, often sub-clinical, but occasionally with acute stomatitis. The virus can pass along nerves and become latent in ganglia from whence it can be reactivated by non-specific stimuli (fever, sunlight, menstruation) to cause lesions, often around the mouth. Rarely, the virus may cause acute hepatitis, kerato-conjunctivitis or meningo-encephalitis. Vaccination has not been successful but treatment of kerato-conjunctivitis and skin lesions with locally applied acyclovir ointment is beneficial. In cases of encephalitis, neonatal herpes or disseminated infection, intravenous acyclovir is used. See Human herpesvirus 2. Synonyms...

Tissue Specific Ablation

In several movement disorders, neurodegeneration of specific neuronal types is observed, such as the dopaminer-gic neurons in Parkinson disease and striatal neurons in Huntington disease. A model that mimics neurodegeneration without regard for the genetics of the disorder can also be achieved with the transgenic approach. A widely used method of genetic ablation of specific tissues relies on the diphtheria toxin A-chain gene (DTA). The toxin gene's expression is controlled by the tissue-specific promoter it is linked to (Breitman et al. 1987 Palmiter et al. 1987). When expressed, the toxin causes cell death. A variation on this technique has been developed that allows for inducibility of the toxin. The promoter of tTA selects for the tissue type and the tet-op promoter drives DTA expression (Lee et al 1998). Another conditional ablation method uses the human inter-leukin 2 receptor that is controlled by a desired promoter. Application of the recombinant immunotoxin anti-Tac(Fv)-PE40...

Approaches of Transcriptional Regulation

Several universal promoters have been utilized to attempt to maximize gene expression. The LTR, CMV, and RSV promoters were isolated from Maloney retrovirus, cytomegalovirus, and Rous sarcoma virus, respectively. These promoter elements were used because of the universal transcriptional activation over a broad host range. This universal transcription allowed for excellent but nondiscriminatory gene transcription and subsequent transgene expression. Because of the high levels of gene expression within several DNA constructs (i.e., viruses, cosmids, plasmids, etc.), these promoters are still used daily throughout the scientific community to test hypotheses which require uniform and high-level gene transcription. These were the promoters utilized in the first wave of gene therapy clinical trials, which focused on maximal gene expression and used local injection techniques to control the region of gene expression achieved. The LTR promoter was used to control herpes simplex virus...

Summary and Discussion

The implementation of a quantitative and noninvasive method capable of monitoring transgene expression in living animals repetitively would be useful toward validating the efficacy of any gene therapy strategy. In this respect, a number of investigators, including those at UCLA, are developing sensitive technologies for imaging transgene expression using positron emission tomography (PET) and optical measurements. PET is a noninvasive, tomographic imaging modality that already has clinical applications for the diagnosis and management of several diseases including cancer. Newer high-resolution animal microPET technology developed at UCLA, is allowing for the study of smaller animal systems (mice, rats, small primates) previously difficult to image with a resolution approaching 2 mm 179 . With relevance to gene therapy for cancer, the herpes simplex virus 1 thymidine kinase (HSVl-tk) gene has been demonstrated to be an excellent PET reporter gene by virtue of trapping positron-emitting...

Dynamic Structures and the Fourth Dimension in CryoEM

Sometimes, the system can be slowed down, and the bottleneck created allows the desired synchronic state to be achieved. Following this strategy, the dynamics of herpes simplex virus maturation was studied after blocking the activity of a protease, since protease-deficient procapsids mature slowly in vitro (Heymann et al. 2003) (Fig. 10.4). Most dynamic structural studies by cryo-EM, however, employ biochemical interference that stalls the macromolecules in a desired step, tte ribosome is the paradigm of this type of characterization, since several natural antibiotics are known to inhibit translation, tte incorporation of specific transfer RNAs (tRNAs) to the ribosome was analyzed thanks to the blockade of the process by kirromycin (Valle et al. 2003a). tte described rearrangements of ribosome and tRNA uncovered a cascade of interrelated events that clarified the structural basis for fidelity during translation.

Transductionally Targeted Ad Vectors for Clinical Gene Therapy Applications

As discussed above, the poor efficiency of Ad-mediated gene transfer in several human gene therapy trials has been correlated with a low level of expression of CAR by the target cells. Strategies to accomplish efficient cell-specific gene transfer by Ad vectors in vivo merely by exploiting physical methods to confine vector administration to isolated body compartments have proven inadequate. For example, locally administered Ad vectors carrying the herpes simplex virus thymidine kinase (HSV-TK) gene have been shown to disseminate, probably as a result of leakage into the bloodstream, resulting in a high level of liver-associated toxicity 119 . Substantial hepatic toxicity related to the absence of tumor cell-specific targeting has also been demonstrated in Ad-mediated transfer of the HSV-TK gene in an ascites model of human breast cancer 120 . Thus, targeted Ad vectors capable of efficient and cell-specific CAR-independent gene transfer are required for clinical gene therapy...

Oral and oesophageal disease

Oral cavity pain or discomfort are caused by candidiasis, herpetic or aphthous ulceration, periodontal disease, and tumours. Often the diagnosis can be made by simple inspection and appropriate treatment initiated without further investigation. Systemic oral therapy of herpes simplex ulceration and candidiasis is preferred for reasons of efficacy and ease of use. Recurrence is common and if frequent, maintenance therapy may be required rather than the short treatment of each occurrence. Maintenance therapy may be more likely to induce resistance. About one third of patients develop oesophageal disease. The likelihood of candidiasis is so high that a therapeutic trial with a systemic antifungal agent is indicated before considering further investigation. If symptoms fail to respond, or recur despite adequate maintenance therapy, endoscopy is performed to exclude herpes simplex, cytomegalovirus and other causes of oesophageal ulceration including malignant lesions.

Central nervous system viral infections

Many viruses such as rabies, measles, mumps and herpes simplex may infect the nervous system and cause serious disease. Viruses may enter the nervous system along nerves and through the blood. Once in the central nervous system viruses may cause acute or slow chronic infections. Cercopithecine herpesvirus 1 (CeHV-1) Cercopithecine herpesvirus 1 (CeHV-1) A species in the family Herpesviridae. A natural infection of Asiatic macaque monkeys. 10 of newly caught rhesus monkeys have antibodies, and the virus is frequently present in kidney cell cultures of this animal. Reservoir species include Macaca mulatta, M. fascicularis, M. fuscata, M. arctoides, M. cyclopsis and M. radiata. Causes vesicular lesions on the tongue and lips, and sometimes of the skin. Infection of humans by monkey bites or other means leads to ascending myelitis or acute encephalitis almost all cases are fatal. Mice under 3 weeks old, day-old chicks and guinea pigs can be infected experimentally. Not all strains are...

Necrotic rhinitis virus Synonym for Bovine herpesvirus 1. neural spread Dissemination of virus infection by spreading along peripheral nerves. Plays an essential role for viruses such as rabies, herpes simplex and pseudorabies viruses, which do not generally spread by viremia. Other viruses such as polio, reovirus and mouse hepatitis may utilize both viremia and neural spread to disseminate infection.

Diagnosis and Treatment

Become resistant to azole therapy in some cases, or be due to other yeasts, such as Torulopsis glabrata, for which intravenous (IV) amphotericin B therapy is required. Therapy options for hairy leukoplakia include Acyclovir 800 mg orally 5 times per day for 2 to 3 weeks, then 1.2 to 2 g d, or Tretinoin (Retin A) 0.025 or 0.05 solution applied 2 to 3 times per day. Herpes simplex virus (HSV) infection responds to oral treatment with acyclovir. Discontinuation of therapy after induction therapy and the use of maintenance therapy only if there are frequent relapses is recommended. Ganciclovir is an effective therapy for CMV esophageal disease (Wilcox et al, 1991). Idiopathic esophageal ulcers not due to identifiable pathogen may respond promptly to corticosteriods, though the danger of worsening immune suppression in patients with AIDS should be kept in mind. The ulcer also may recur after steroid therapy is discontinued. Studies have shown the effectiveness of thalidomide for the...

Pregnancy-related FHF should be treated with early delivery along with administration of corticosteroids to foster maturation of the fetal lungs. Copper chelation is very effective for chronic Wilson's disease, but rarely effective in fulminant Wilson's in which liver transplantation is usually the only option. Other potentially beneficial but unproven therapies include high dose corticosteroids for fulminant autoimmune hepatitis, and lamivudine (and or adefovir), acyclovir, or ganciclovir for FHF secondary to HBV, HSV, or CMV infection, respectively. In all of these situations, specific therapy should not delay evaluation and listing for transplant in suitable candidates.

Selectable Markers and Gene Amplification in Animal Cells

The inosinate cycle for the salvage of purine bases and the production of inosine monophosphate) and therefore unable to grow in medium containing hypoxanthine, aminopterin and thymidine (HAT, which blocks de novo inosine monophosphate production (Lester etal., 1980)) were transfected with total genomic DNA from a wild-type cell line. Very rarely, cells could be isolated that were able to grow in this medium, indicating that they had acquired the ability to make HPRT from the wild-type cells (Szybalska and Szybalski, 1962). Similarly, mouse cells deficient in the enzyme thymidine kinase (TK, which is part of the nucleotide biosynthesis salvage pathway) are unable to grow on HAT medium, but can be transfected with the herpes simplex virus (HSV) Tk gene to allow growth on this medium (Wigler etal., 1977). A number of other such metabolic markers have also been used to monitor the transfec-tion process, but they all suffer from the requirement of a mutant cell line in order to detect...

Inducible Transgenic Systems

Widespread alteration in a gene's expression pattern from the beginning of development may disrupt normal growth to a severity that produces unhealthy animals, which could complicate analyses or even render the animals of no use. Also, compensatory mechanisms may occur during development that mask the effects of the transgene. In these cases, control over the time of transgene expression is necessary. Several systems have been developed to meet that need. The Tet system is the most widely used. Two variations of this system have been devised that differ in whether or not the gene is expressed constitutively and when exposed to an exogenous compound. The original strategy is the Tet-off system (Figure 2). In this system, an additional mouse line is produced to express tetracycline-controlled trans-activator (tTA) in the tissue(s) of interest. tTA is a fusion protein containing a tet repressor from E. coli transposon Tn 10 and the activating domain of virion protein 16 of herpes simplex...

Penciclovir A drug related to acyclovir which is selectively phosphorylated by the HSV thymidine kinase and inhibits replication of herpesviruses such as VZV and CMV as well as HSV. It is licensed as a cream for use against oral herpes. Because it was not effective orally, the 6-deoxydiacetyl ester derivative famciclovir was developed as an orally delivered prodrug of penciclovir and is now licensed for treatment, especially of herpes zoster infections in immunosup-pressed patients. It is also effective against hepatitis B.

Viral Infections In Aging Humans

Viral infection begins with attachment of virions to host cells. Specific attachment that leads to virion penetration generally depends upon complementary interaction between viral protein (counter-receptor or anti-receptor) and specific receptors on host cells. Viruses may display a single species of protein counter-receptor or multiple species of counter-receptors in the case of some complex viruses such as herpes simplex. Whether or not a host cell is susceptible to a given virus depends upon the cell having receptors. Cells lacking receptors are not susceptible. If a host cell supports the complete reproduction of a given virus, it is termed permissive. Some host cells can be shown to be permissive but not susceptible because they lack the appropriate receptors. Herpes simplex Proteoglycans Oral and genital epithelium

Congenital infection Infection occurring before birth. May follow a number of viral infections and is sometimes lethal. May produce fetal abnormalities, e.g. Rubella virus and Human herpesvirus 5. Some viruses affect particular organs depending on the stage of fetal development at which infection occurs, while others which are non-cytocidal may infect every cell in the embryo and persist throughout adult life, e.g. Lymphocytic choriomeningitis virus in mice.

General physical examination

Additionally, unless meningitis can be excluded by the clear identification of another cause for coma, it should be assumed present as the consequence of missed diagnosis is catastrophic and the risk of unnecessary treatment with antibiotics small. Acyclovir should also be considered as herpes encephalitis has a worse prognosis when treatment is seriously delayed. Senior advice should be sought. Lumbar puncture should not be performed in a child in coma. It can be performed some days later when the child's condition allows, to confirm or refute the diagnosis of meningitis encephalitis if antibiotic treatment acyclovir has been started (see page 134).

Structural features of nucleosides as antiviral agents

Some viruses, such as herpes viruses, encode their own nucleoside-phosphorylat-ing enzymes, which offers the potential for a therapeutic target.6 Nucleosides, which are preferably phosphorylated by viral enzymes rather than by the cellular homologue, are only activated in infected cells and can have high selectivity against these viruses. This is, for example, the main factor in the success of acyclovir (ACV). However, other viruses, such as HIV and HBV, do not encode nucleoside kinases. In order to be active against these viruses, nucleoside analogs have to be phosphorylated by cellular kinases. Thus, the selectivity between antiviral activity and cellular toxicity depends on the substrate specificity of the NTPs for viral and host polymerases, and often the therapeutic exploitation of active nucleosides is compromised by the toxicity resulting from inhibition of the host enzymes or incorporation in the host nucleic acids. In general, enzymes act on one enantiomer of a chiral...

Subacute myeloopticoneuropathy virus

(SMON) A herpesvirus isolated from the feces and CSF of patients with subacute myelo-optico-neuropathy. Seen mainly in Japan, the disease is characterized by sensory disturbance, especially of the lower part of the legs, abdominal symptoms, decreased muscle strength and bilateral impairment of visual acuity. There are no changes in the blood or CSF. There is degeneration of posterior and lateral tracts of the spinal cord. The virus was isolated in BAT-6 cells and causes a thinning of the cell sheet. On injection into newborn C57Bl 6 mice it is reported to cause paralysis of the hind legs. It is claimed that the virus can be derived on passage of avian infectious laryngotra-cheitis virus on the CAM or in newborn C57BL 6 mice. It is antigenically related to this virus but is said to differ from it in being non-pathogenic for fowls, less unstable at low pH and pathogenic for C57BL 6 mice.

UdR See fluorodeoxyuridine

Fusion of cells The formation of multi-nucleate giant cells known as poly-karyocytes or syncytia. Can be caused by a variety of agents including some viruses, notably Paramyxoviridae. There are two types of virus-induced fusion. (1) Fusion from without. Not dependent on virus replication or on the synthesis of new proteins. Occurs not more than 1-3 h after exposure to high multiplicities of most of the large enveloped RNA viruses or certain DNA viruses such as Human herpesviruses 1 and 2 and Vaccinia virus, even when they have been inactivated by UV light or P-propiolactone. May also be caused by viral hemolysin, since treatment which will destroy this enzyme activity without affecting viral infectivity will also prevent the cell-fusing action. (2) Fusion from within. Begins several hours after infection and depends on synthesis of viral proteins, especially the F protein of paramyx-oviruses. Production of new infectious virus is not necessary. Often most marked after infection at low...

Quail adenovirus See fowl adenovirus

Subunits forming the icosahedral capsid should be capable of assembling into both hexamers and pentamers. The insertion of 12 pentamers produces curvature in the sheet of hexamers where they are inserted, resulting in a closed icosahedral shell that is not strictly equivalent, but forms a more stable structure. Thus icosahedral viruses have a capsid composed of 12 pentamers and a variable number of hexamers, e.g. herpesviruses have 150 hexamers and 12 pentamers, making up the capsid adenoviruses have 240 hexamers and 12 pentamers.

DNA exonuclease See deoxyribonuclease exonuclease

Triphosphates and a primer with a free 3'-hydroxyl group. The primer can be an uncompleted DNA strand, but is more usually a short RNA strand. Synthesis of at least one strand is discontinuous and yields a series of Okazaki fragments. Three types of DNA polymerase have been described in prokaryotes. DNA polymerase I (Kornberg enzyme) has a 5'-3' exonucle-ase activity as well as polymerase activity and is mainly involved in repair synthesis of DNA. DNA polymerase II has a 3'-5' nuclease activity but lacks the 5'-3' nucle-ase activity. DNA polymerase III has both 5'-3' and 3'-5' exonuclease activities and appears to be the true DNA replicating enzyme in Escherichia coli the role of DNA polymerase II is uncertain. In eukaryotic cells, four distinct species of DNA poly-merase have been described. (1) DNA polymerase alpha has a high molecular weight and contains associated DNA primase activity it is the major enzyme involved in DNA replication. (2) DNA polymerase beta is a low molecular...

Or 4Membered ring nucleosides

The active enantiomer of carbocyclic OXT-G (141, lobucavir, LBV, Figure 56) displays an impressive broad-spectrum antiviral activity against a wide variety of herpesviruses and HBV as well as HIV.247 The mechanism of action of LBV against HSV-1, HSV-2 and VZV consists in the inhibition of the viral polymerases after phosphorylation by the virally encoded TK (Figure 57).247 However, HCMV, HBV and HIV do not encode enzymes which are capable of mediating LBV phosphorylation. It is known that HCMV has homologs of a herpesvirus-encoded protein kinase (UL97 gene), which mediates the phosphorylation of ganciclovir (GCV). In the case of VZV, both the herpesvirus TK and protein kinase may independently enable the phosphorylation of LBV. Furthermore, LBV is phosphorylated to its triphosphate intracellularly in both HCMV-infected and uninfected cells, with phosphorylated metabolites levels 2- to 30-fold higher in infected cells. These studies247 suggest that LBVTP can halt HCMV DNA replication...

Porcine transmissible gastroenteritis virus

Post-transcriptional modification Alterations in the structure of RNA transcripts prior to utilization as mRNA. These may include splicing, capping with a blocked methylated structure at the 5' end, addition of poly A at the 3' end, or methylation of certain bases internally in the RNA, particularly adenylic and cytidylic acids. These modifications all occur in most species of eukaryotic cell mRNA, and are apparently accomplished by enzymes in the cell nucleus. Viral RNA transcripts synthesized within the cell nucleus (e.g. Orthomyxoviridae, Retroviridae, Papovaviridae, Adenoviridae and Herpesviridae) may be modified by these cell enzymes. Viruses replicating wholly in the cytoplasm (e.g. Paramyxoviridae, Rhabdoviridae, Picorna-viridae, Togaviridae and Poxviridae) carry similar enzymes in the virion or induce their synthesis in infected cells.
