Novel endotheliotropic herpesviruses fatal for Asian and African elephants. (1/2429)

A highly fatal hemorrhagic disease has been identified in 10 young Asian and African elephants at North American zoos. In the affected animals there was ultrastructural evidence for herpesvirus-like particles in endothelial cells of the heart, liver, and tongue. Consensus primer polymerase chain reaction combined with sequencing yielded molecular evidence that confirmed the presence of two novel but related herpesviruses associated with the disease, one in Asian elephants and another in African elephants. Otherwise healthy African elephants with external herpetic lesions yielded herpesvirus sequences identical to that found in Asian elephants with endothelial disease. This finding suggests that the Asian elephant deaths were caused by cross-species infection with a herpesvirus that is naturally latent in, but normally not lethal to, African elephants. A reciprocal relationship may exist for the African elephant disease.  (+info)

Microsatellite instability, Epstein-Barr virus, mutation of type II transforming growth factor beta receptor and BAX in gastric carcinomas in Hong Kong Chinese. (2/2429)

Microsatellite instability (MI), the phenotypic manifestation of mismatch repair failure, is found in a proportion of gastric carcinomas. Little is known of the links between MI and Epstein-Barr virus (EBV) status and clinicopathological elements. Examination of genes mutated through the MI mechanism could also be expected to reveal important information on the carcinogenic pathway. Seventy-nine gastric carcinomas (61 EBV negative, 18 EBV positive) from local Hong Kong Chinese population, an intermediate-incidence area, were examined. Eight microsatellite loci, inclusive of the A10 tract of type II transforming growth factor beta receptor (TbetaR-II), were used to evaluate the MI status. MI in the BAX and insulin-like growth factor II receptor (IGF-IIR) genes were also examined. High-level MI (>40% unstable loci) was detected in ten cases (12.7%) and low-level MI (1-40% unstable loci) in three (3.8%). High-level MI was detected in two EBV-associated cases (11%) and the incidence was similar for the EBV-negative cases (13%). The high-level MIs were significantly associated with intestinal-type tumours (P = 0.03) and a more prominent lymphoid infiltrate (P = 0.04). Similar associations were noted in the EBV-positive carcinomas. The high-level MIs were more commonly located in the antrum, whereas the EBV-associated carcinomas were mostly located in body. Thirteen cardia cases were negative for both high-level MI and EBV. All patients aged below 55 were MI negative (P = 0.049). Of the high-level MIs, 80% had mutation in TbetaR-II, 40% in BAX and 0% in IGF-IIR. Of low-level MIs, 33% also had TbetaR-II mutation. These mutations were absent in the MI-negative cases. Of three lymphoepithelioma-like carcinomas, two cases were EBV positive and MI negative, one case was EBV negative but with high-level MI. In conclusion, high-level MIs were present regardless of the EBV status, and were found in a particular clinicopathological subset of gastric carcinoma patient. Inactivation of important growth regulatory genes observed in these carcinomas confirms the importance of MI in carcinogenesis.  (+info)

Lymphomatoid granulomatosis following autologous stem cell transplantation. (3/2429)

Lymphomatoid granulomatosis (LYG) is a rare angio-destructive lymphoproliferative disorder (LPD) of uncertain etiology, with prominent pulmonary involvement. Recent studies indicate that LYG is an Epstein-Barr virus (EBV)-associated B cell LPD with large numbers of background reactive T lymphocytes (T cell-rich B cell lymphoma). Although the disease frequently, but not exclusively, occurs in various immunodeficiency states, it has not been reported in association with the transient immunosuppression following autologous bone marrow/peripheral stem cell transplantation (ABM/PSCT). We describe a patient who developed lymphomatoid granulomatosis of the lung approximately 2 weeks after high-dose chemotherapy and autologous peripheral stem cell transplantation for multiple myeloma. Although molecular studies showed no evidence of EBV genome in the biopsy material, the serologic profile with high IgM titers was suggestive of primary EBV infection. Complete radiologic remission occurred following reconstitution of the patient's immune response after a 2-week course of ganciclovir treatment. Despite the apparently low frequency of LPD (both LYG and EBV-associated post-transplant lymphoma) in the ABMT setting, we believe that it should be considered in the differential diagnosis of patients whose clinical course following ABMT is complicated by fevers, in the absence of an identifiable infectious process.  (+info)

Phenotypic and functional characterization of CD8(+) T cell clones specific for a mouse cytomegalovirus epitope. (4/2429)

A series of CD8(+) T cell clones, specific for the IE1 epitope YPHFMPTNL, of the immediate-early protein 1 of the murine cytomegalovirus (MCMV) were generated in order to determine their protective activity against this infection and correlate their phenotypic markers with antiviral activity. We found that the adoptive transfer of three of these anti-MCMV CD8(+) T cell clones into irradiated naive mice resulted in protection against challenge, while another CD8(+) T cell clone, of the same specificity, failed to confer protection. The clones that conferred protection against lethal challenge reduced greatly viral replication in the lung and other organs of the mice. Using one of the protective anti-MCMV CD8(+) T cell clones we found that in order to be fully protective the cells had to be transferred to recipient mice no later than 1 day after MCMV challenge. The adoptive transfer of these CD8(+) T cell clones also protected CD4(+) T-cell-depleted mice. Phenotypic characterization of the anti-MCMV clones revealed that the nonprotective clone expressed very low levels of CD8 molecules and produced only small amounts of TNF-alpha upon antigenic stimulation. Most importantly, our current study demonstrates that this MHC class I-restricted IE1 epitope of MCMV is efficiently presented to CD8(+) T cell clones in vivo and further strengthens the possibility of the potential use of CD8(+) T cell clones as immunotherapeutic tools against cytomegalovirus-induced disease.  (+info)

Human herpesviruses in chronic fatigue syndrome. (5/2429)

We have conducted a double-blind study to assess the possible involvement of the human herpesviruses (HHVs) HHV6, HHV7, Epstein-Barr virus (EBV), and cytomegalovirus in chronic fatigue syndrome (CFS) patients compared to age-, race-, and gender-matched controls. The CFS patient population was composed of rigorously screened civilian and Persian Gulf War veterans meeting the Centers for Disease Control and Prevention's CFS case definition criteria. Healthy control civilian and veteran populations had no evidence of CFS or any other exclusionary medical or psychiatric condition. Patient peripheral blood mononuclear cells were analyzed by PCR for the presence of these HHVs. Using two-tailed Fisher's exact test analyses, we were unable to ascertain any statistically significant differences between the CFS patient and control populations in terms of the detection of one or more of these viruses. This observation was upheld when the CFS populations were further stratified with regard to the presence or absence of major axis I psychopathology and patient self-reported gradual versus acute onset of disease. In tandem, we performed serological analyses of serum anti-EBV and anti-HHV6 antibody titers and found no significant differences between the CFS and control patients.  (+info)

Persistently high Epstein-Barr virus (EBV) loads in peripheral blood lymphocytes from patients with chronic active EBV infection. (6/2429)

Chronic active Epstein-Barr virus infection (CAEBV) is a severe illness with unusual EBV activation that persists for years, and its pathogenesis is largely unknown. After the creation of an accurate and reproducible polymerase chain reaction system to quantify EBV DNA, virus loads in peripheral blood lymphocytes (PBL) were determined in 54 children: 15 with CAEBV, 16 with infectious mononucleosis (IM), and 23 healthy children. Children with CAEBV and those with IM had high virus loads. Lower loads were detected in 47% of seropositive healthy donors. There were two distinct differences between children with CAEBV and those with IM: The former had greater viral replication (10(3)-10(7) copies/2.5x10(5) PBL) than those with IM, and viral replication declined in children with IM whereas active replication persisted for years in subjects with CAEBV. Persisting high virus loads are a possible diagnostic criterion for CAEBV. EBV loads may enable classification and prognosis of EBV infections.  (+info)

High seroprevalence of antibodies to human herpesvirus-8 in Egyptian children: evidence of nonsexual transmission. (7/2429)

BACKGROUND: In western countries, human herpesvirus-8 (HHV-8) appears to be transmitted mainly by sexual contact. To evaluate the role of other transmission routes, especially in developing countries, we estimated the seroprevalence of HHV-8 in Egyptian children, who, if seropositive, would have acquired the virus through a nonsexual route. METHODS: Sera from 196 children (<1-12 years of age), 20 adolescents (13-20 years of age), and 30 young adults (21-25 years of age) attending a vaccination program in Alexandria, Egypt, were studied. Immunofluorescence assays were used to detect antibodies against HHV-8 lytic-phase antigens (anti-lytic) and latent-phase antigens (anti-latent). Antibodies against Epstein-Barr virus viral cap antigen, cytomegalovirus, and HHV-6 were detected by enzyme-linked immunosorbent assays. Seroprevalence of these herpesviruses was calculated after stratifying the subjects by age. RESULTS: Anti-lytic and anti-latent HHV-8 antibodies were detected in 44.7% and 8.5% of the study participants, respectively. The prevalence of anti-lytic antibodies tended to increase with age, exceeding 50% in children older than 6 years; once children reached the age of 10 years, the prevalence tended to stabilize. The seroprevalence of other herpesviruses tended to be higher than that of HHV-8, ranging from approximately 83% to more than 97% in the 9- to 12-year age group. One- to 3-year-old children had higher titers of antilytic HHV-8 antibodies than children in the other age groups. Anti-latent antibodies were more frequently detected in individuals with high anti-lytic antibody titers. CONCLUSIONS: HHV-8 antibodies are highly prevalent in Egyptian children, suggesting that, in developing countries, HHV-8 infection may be acquired early in life through routes other than sexual transmission. The lower seroprevalence of HHV-8 relative to that of the other herpesviruses suggests that HHV-8 is less transmissible than other common herpesviruses.  (+info)

Immunological control of a murine gammaherpesvirus independent of CD8+ T cells. (8/2429)

Adult thymectomized C57 BL/6J mice were depleted of T cell subsets by MAb treatment either prior to, or after, respiratory challenge with murine gammaherpesvirus-68. Protection against acute infection was maintained when either the CD4+ or the CD8+ T cell population was greatly diminished, whereas the concurrent removal of both T cell subsets proved invariably fatal. The same depletions had little effect on mice with established infection. The results indicate firstly that both CD4+ and CD8+ T cells play a significant part in dealing with the acute infection, and secondly that virus-specific antibody contributes to controlling persistent infection with this gammaherpesvirus.  (+info)

A study finds that atopic patients may present with atypical herpesvirus infections that may be misdiagnosed as drug allergy or autoimmune disease.
Researchers identified a set of protein complexes that are recruited to viral genes and stimulate both initial infection and reactivation of herpes virus
Many acute viral infections can be controlled by vaccination; however, vaccinating against persistent infections remains problematic. Herpesviruses are a classic example. Here, we discuss their immune control, particularly that of gamma-herpesviruses, relating the animal model provided by murid herpesvirus-4 (MuHV-4) to human infections. The following points emerge: (i) CD8+ T-cell evasion by herpesviruses confers a prominent role in host defence on CD4+ T cells. CD4+ T cells inhibit MuHV-4 lytic gene expression via gamma-interferon (IFN-γ). By reducing the lytic secretion of immune evasion proteins, they may also help CD8+ T cells to control virus-driven lymphoproliferation in mixed lytic/latent lesions. Similarly, CD4+ T cells specific for Epstein-Barr virus lytic antigens could improve the impact of adoptively transferred, latent antigen-specific CD8+ T cells. (ii) In general, viral immune evasion necessitates multiple host effectors for optimal control. Thus, subunit vaccines, which tend to prime
Human herpesviruses are characterized by distinct states of infection. analyzed expression of EBV latent genes and investigated their contribution to the unique histologic phenotype of HLP. Coexpression of lytic and transforming viral proteins was detected simultaneously within individual HLP keratinocytes. LMP1 has now been shown to be uniformly expressed in the affected tissue and it is associated and colocalizes with tumor necrosis factor receptor-associated factor (TRAF) signaling molecules. Effects induced by activated TRAF signaling that were detected in HLP included activation of NF-κB and c-Jun terminal kinase 1 (JNK1) and upregulated expression of epidermal growth factor receptor (EGFR) CD40 A20 and TRAFs. This study identifies a novel state of EBV infection with concurrent expression of replicative and transforming proteins. It is probable that both replicative and latent proteins contribute to HLP development and induce many of the histologic features of HLP such as acanthosis and ...
Antibody is an important antiviral defence. However, it is considered to do little against human gamma-herpesviruses, which establish predominantly latent infections regulated by T cells. One limitation on analysing these infections has been that latency is already well-established at clinical presentation; early infection may still be accessible to antibody. Here, using murid herpesvirus-4 (MuHV-4), we tested the impact of adoptively transferred antibody on early gamma-herpesvirus infection. Immune sera and neutralizing and non-neutralizing monoclonal antibodies (mAbs) all reduced acute lytic MuHV-4 replication. The reductions, even by neutralizing mAbs, were largely or completely dependent on host IgG Fc receptors. Therefore, passive antibody can blunt acute gamma-herpesvirus lytic infection, and does this principally by IgG Fc-dependent functions rather than by neutralization ...
en] Herpesviruses consistently transmit from immunocompetent carriers, implying that their neutralization is hard to achieve. Murid Herpesvirus-4 (MuHV-4) exploits host IgG Fc receptors to bypass blocks to cell binding, and pH-dependent protein conformation changes to unveil its fusion machinery only after endocytosis. Nevertheless neutralization remains possible by targeting the virion glycoprotein H (gH) / gL heterodimer, and the neutralizing antibody responses of MuHV-4 carriers are improved by boosting with recombinant gH/gL. We analysed here how gH/gL-directed neutralization works. The MuHV-4 gH/gL binds to heparan sulfate. However most gH/gL-specific neutralizing antibodies did not block this interaction. Nor did they act directly on fusion. Instead they blocked virion endocytosis and transport to the late endosomes where membrane fusion normally occurs. The poor endocytosis of gH/gL-neutralized virions was recapitulated precisely by virions genetically lacking gL. Therefore driving virion ...

HPV- and herpes virus infections: epidemiological, pathogenetic and clinical immunological aspects, principles of diagnosis and therapy
There are eight herpesviruses (HHV 1-8) that are endemic within the human population. Whilst primary infection can often result in mild or asymptomatic illness, herpesviruses are the principal causative agents associated with a number of severe and potentially life-threatening diseases. A common feature shared by all herpesviruses is their ability to establish a life-long latent infection within their host, which can periodically undergo episodes of viral reactivation leading to recurrent disease and transmission. Antivirals (acyclovir, valacyclovir, and famciclovir) are effective at limiting viral spread, but do not inhibit viral reactivation from latency and carry health risks with prolonged use. Understanding the molecular mechanisms that regulated the balance between lytic (active) and latent (silent) states of infection remains an important area of research that may provide novel avenues in the development of new or alternative antiviral therapies.. The post-translational modification (PTM) ...
In vertebrates, successful host defense against viral infections relies heavily on the early production of IFN-α/β, which promotes an antiviral state in adjacent noninfected cells as well as the activation of antiviral cytotoxic lymphocytes (1). IL-12 and TNF-α are also critical cytokines involved in antiviral defense. IL-12 stimulates the proliferation of T cells as well as the production of IFN-γ by both NK and T cells, whereas TNF-α takes part in the activation of cellular immunity and in the induction of apoptosis of infected cells. Plasmacytoid dendritic cells (pDCs)3 have been shown to be specialized in the production of high levels of IFN-α/β and TNF-α in response to a wide variety of viruses in both humans and mice (2).. The molecular mechanisms promoting the production of cytokines by pDCs in response to most viral infections are independent of productive viral replication within the pDC itself and rely on the detection of viral genomes from engulfed viral particles or apoptotic ...

Control of gammaherpesvirus infections requires a complex, well orchestrated immune response regulated by positive and negative co-signaling molecules. While the impact of co-stimulatory molecules has been addressed in various studies, the role of co-inhibitory receptors has not been tested. The ITIM-bearing CEACAM1 is an inhibitory receptor expressed by a variety of immune cells, including B, T and NK cells. Using Ceacam1(-/-) mice, we analyzed the in vivo function of CEACAM1 during acute and latent murine gammaherpesvirus 68 (MHV-68) infection. During acute lytic replication, we observed lower virus titers in the lungs of Ceacam1(-/-) mice than in WT mice. In contrast, during latency amplification, Ceacam1(-/-) mice displayed increased splenomegaly and a higher latent viral load in the spleen. Analysis of the immune response revealed increased virus-specific antibody levels in Ceacam1(-/-) mice, while the magnitude of the T cell-mediated antiviral immune response was reduced. These findings ...
Currently the hu-BLT mouse model has been used mostly to study HIV-1 and a limited number of other viruses (9, 11⇓⇓-14). Little is known whether this model can be used to study KSHV infection, for which there is no good small-animal model to study its infection and disease pathogenesis. We demonstrated in this study that the hu-BLT mice can be infected via several known natural routes of infection, such as via oral and vaginal mucosal routes. We also found that a large number of human B cells and macrophages, which are known natural human host cells, were infected. Our finding represents an important step forward toward developing a robust small-animal model for KSHV infection and disease pathogenesis.. It has been shown that KSHV DNA could be detected in rhesus macaques inoculated with KSHV-infected PEL cells, but it replicated to very low levels, and viral mRNA was not detectable (15). In addition, Chang et al. (16) recently reported that KSHV can establish persistent infection in ...
Murine gammaherpesvirus 68 (MHV-68) aka murid herpesvirus 68 is an isolate of Murid herpesvirus 4 which is a virus in the genus Rhadinovirus. It is a member of the subfamily Gammaherpesvirinae in the family of Herpesviridae. MHV-68 serves as a model for study of human gammaherpesviruses which cause significant human disease including B-cell lymphoma and Kaposis sarcoma. The WUMS strain of MHV-68 was fully sequenced and annotated in 1997, and the necessity of most of its genes in viral replication was characterized by random transposon mutagenesis study . Alpha-, beta-, and gammaherpesviruses display a heterodimer composed of glycoprotein H (gH) and glycoprotein L (gL) on their envelopes. This receptor is involved in the cell-to-cell transmission of the virus. Glycoprotein H has two conformations. Glycoprotein L is a chaperone protein which assures that gH takes on the correct conformation. When herpesviruses lack gL, gH misfolds. When alpha- or betaherpesviruses lack gL, they are noninfectious. ...

KSHV vGPCR, a lytic cycle associated protein, induces several signaling pathways leading to the activation of various transcription factors and consequently the expression of cellular and viral genes. Though the role of vGPCR in KSHV tumorigenicity has been well studied, its function related to the viral life cycle is poorly understood. Reduction in vGPCR by RNA interference also resulted in the reduction in KSHV lytic switch ORF50 gene and protein expression. Induction of vGPCR by doxycycline in BC3.14 cells also resulted in more KSHV production. When this was explored, induction of the ORF50 promoter by vGPCR expression was observed. Further examination of the molecular mechanisms by which vGPCR regulates the ORF50 promoter, using various ORF50 promoter constructs, revealed that induction of ORF50 promoter by vGPCR did not involve AP1 but was dependent on Sp1 and Sp3 transcription factors. vGPCR signaling led to an increase in Sp1 and Sp3 DNA binding activity and a decrease in histone ...

Herpesviruses are large, spherical, enveloped viral particles with linear double-stranded DNA genome. Herpesvirus virion consists of an icosahedral capsid containing viral DNA, surrounded by a protein layer called tegument, and enclosed by an envelope consisting of a lipid bilayer with various glycoproteins. Herpesviruses persist lifelong in their hosts after primary infection by establishing a latent infection interrupted recurrently by reactivations. The Herpesviridae family is divided into three subfamilies; α-herpesviruses, β-herpesviruses, and γ-herpesviruses based on the genome organization, sequence homology, and biological properties. There are eight human herpes viruses: Herpes simplex virus type 1 and 2 (HSV-1, −2) andVaricella-zoster virus (VZV), which belong to the α-herpesvirus subfamily; Human cytomegalovirus (HCMV), and Human herpesvirus type 6 and 7 ...
Herpesviruses characteristically transmit infection from immune hosts. Although their success in escaping neutralization by pre-formed antibody is indisputable, the underlying molecular mechanisms remain largely unknown. Glycoprotein B (gB) is the most conserved component of the herpesvirus entry machinery and its N terminus (gB-NT) is a common neutralization target. We used murid herpesvirus-4 to determine how gB-NT contributes to the virus-antibody interaction. Deleting gB-NT had no obvious impact on virus replication, but paradoxically increased virion neutralization by immune sera. This reflected greater antibody access to neutralization epitopes on gH/gL, with which gB was associated. gB-NT itself was variably protected against antibody by O-linked glycans; on virions from epithelial cells it was protected almost completely. gB-NT therefore provides a protective and largely protected cover for a vulnerable part of gH/gL. The conservation of predicted glycosylation sites in other mammalian ...
Kaposis sarcoma (KS) is a vascular tumor predominantly found in the immunosuppressed. Epidemiologic studies suggest that an infective agent is the etiologic culprit. Kaposis sarcoma-associated herpesvirus (KSHV), or human herpesvirus-8 (HHV-8), is a gamma human herpesvirus present in all epidemiol …
Herpes B virus is an alpha herpesvirus that is particularly enzootic (endemic in animals) in the rhesus (Macaca mulatta) and cynomolgus (Macaca fascicularis) members of the macaque genus, Macaca (as seen in the image below). Among the nonhuman-primate herpesviruses, only herpes B virus is clearly able to cause disease in humans.
Gammaherpesviruses encode proteins with homology to the cellular purine metabolic enzyme formyl-glycinamide-phosphoribosyl-amidotransferase (FGARAT), but the role of these viral FGARATs (vFGARATs) in the pathogenesis of a natural host has not been investigated. We report a novel role for the ORF75A vFGARAT of murine gammaherpesvirus 68 (MHV68) in infectious virion production and colonization of mice. MHV68 mutants with premature stop codons in orf75A exhibited a log reduction in acute replication in the lungs after intranasal infection, which preceded a defect in colonization of multiple host reservoirs including the mediastinal lymph nodes, peripheral blood mononuclear cells, and the spleen. Intraperitoneal infection rescued splenic latency, but not reactivation. The 75A.stop virus also exhibited defective replication in primary fibroblast and macrophage cells. Viruses produced in the absence of ORF75A were characterized by an increase in the ratio of particles to PFU. In the next round of ...

Kaposis sarcoma-associated herpesvirus vOX2 protein: inhibits neutrophil function and can contribute to immune dysfunction and could have anti-inflammatory therapeutic potential
Dendritic cells (DC) are a heterogeneous family of innate immune cells with crucial functions in host defense against invading pathogens, including viruses. Immature myeloid DC such as Langerhans cells (LC) and dermal DC are strategically located in the skin and mucosae, where they are among the first cell types to encounter viruses during entry. Contact with pathogens is followed by their maturation and migration to the secondary lymphoid organs, where they stimulate naïve T and B cells to proliferate and differentiate into CD8+ or CD4+ T lymphocytes, and into antibody-producing plasma cells. Plasmacytoid DC, by contrast, are mostly found in blood, where they exert potent anti-viral functions by producing vast amounts of interferon-α and -β. Both types of DC play pivotal roles in herpesvirus infections. Horizontal transmission of all herpesviruses occurs primarily by contact with host mucosae, where virions are bound to encounter resident myeloid DC. While this interaction

HHV-8 is sometimes called KS-associated herpes virus (KSHV).. HHV-8 is relatively common among men who have sex with men (MSM) and is generally uncommon in otherwise-healthy heterosexual men and women in high-income countries. HHV-8 is very likely spread by sexual contact. However, exactly which sexual behaviours spread HHV-8 is controversial and not clear.. HHV-8 is found in the saliva of infected people. Presumably such viruses are produced by HHV-8-infected B-cells found in the tonsils or nearby lymph nodes and tissues in the mouth and throat, or perhaps even in the cells lining the throat. These findings suggest that oral sex and other exposures to saliva (wet kissing, oral-anal contact) might be ways that HHV-8 is spread. However, researchers have not conducted the large, expensive and labour-intensive studies necessary to prove this.. In this issue of TreatmentUpdate, we discuss complications arising from HHV-8 infection.. - Sean R. Hosein. ...
Our previous studies have shown that MHV-68 Rta is sufficient to reactivate MHV-68 and drive the lytic cycle to completion in latently infected B cells (26). In this study, the function of Rta during productive infection of permissive 293T and BHK-21 cells was examined. We constructed two mutants of MHV-68 Rta, Rd1 and Rd2, with 112 (Rd1) and 243 (Rd2) aa deleted from the C terminus, where the putative trans-activation domain is located. Rd1 and Rd2 were unable to activate the MHV-68 ORF57 promoter and functioned as dominant-negative mutants to inhibit trans-activation of wild-type Rta. Cotransfection of the Rd1 or Rd2 expression plasmid with MHV-68 virion DNA suppressed the synthesis of viral proteins and the production of infectious virions. Furthermore, viral lytic replication was inhibited in cells constitutively expressing Rd2. Therefore, these results provide strong evidence supporting the pivotal role of Rta during productive infection of permissive cells by MHV-68 in addition to viral ...
Protection against viruses is provided by the host innate, adaptive and cellular intrinsic immunities. Cellular intrinsic immunity, or intrinsic defence, against herpesviruses is in part enacted by components that constitute nuclear substructures known as ND10. ND10 (also called PML nuclear bodies after its major organising component) are dynamic nuclear domains that contain various cellular proteins, including PML itself, Sp100, hDaxx and ATRX. In the early stages of infection, herpesvirus genomes and sites of immediate early transcription become associated with ND10 and their components. Representative herpesviruses such as an alphaherpesvirus HSV-1 and a betaherpesvirus HCMV encode for strong transcriptional activators, namely the Immediate Early protein ICP0 and the tegument protein pp71, respectively. These proteins are known to counteract cellular intrinsic defence mechanisms. In the context of HSV-1 and HCMV infections, the major ND10 component PML has been identified as an important ...

Researchers at the University of Pennsylvania School of Medicine have shed new light on how Kaposis Sarcoma-associated Herpes Virus (KSHV) subverts normal cell machinery to cause cancer. A KSHV protein called latency-associated nuclear antigen, LANA for short, helps the virus hide out from the immune system in infected cells. When LANA takes the place of other proteins that control cell growth, it can cause uncontrolled cell replication.
October 2nd 1999. WHAT IS A VIRUS AND HOW IS IT STRUCTURED?. Viruses are the smallest of the parasites living within cells (intracellular). Viruses do not replicate by dividing their component parts and then splitting into two (binary fission) as bacteria do. They have no energy generating system and do not possess many of the enzymes necessary for making nucleic acid. Furthermore, they do not have the means to translate genetic information into protein. Viruses can therefore only replicate by using the material and machinery provided by their host cell.. The simplest viruses consist of just nucleic acid and protein. The larger viruses have a more complex structure and consist of carbohydrate and lipid material as well.. A virus only ever has one type of nucleic acid; either RNA or DNA, but never both. It is here that the genetic information of the virus is contained.. The nucleic acid, or genome of a virus is large enough to code for between 5 to 100 proteins. These are structural proteins and ...
The ability to establish lifelong latency after primary infection is a common denominator of large DNA viruses of the Herpesviridae family. Herpes viruses are endemic to humans worldwide and contribute to the meta-genome of 70-100% of the worlds population. The significance of herpes viruses as pathogens has been increasingly recognized during the past few decades, with the escalation in the number of patients undergoing immunosuppressive therapy after organ or bone marrow transplantation, and the rising incidence of AIDS. The ability of these viruses to ensure their survival by controlling cellular and immunological functions [1] has focused attention on their potential role in the development of vascular [2] and autoimmune syndromes [3], cancers [4], and as possible co-factors for acquisition of HIV [5]. In addition, these viruses have co-evolved with, and shaped, the immune systems of their hosts. The secrets of immunology can only be unlocked efficiently by using well-adapted pathogens like ...
Herpetic cytomegalovirus (CMV) infection before birth increases the odds that a newborn will go on to develop pediatric acute lymphoblastic leukemia.
Kaposi sarcoma (KS), a potentially fatal cancer especially in immunodeficient individuals, is caused by human herpes virus-8 (HHV-8), a carcinogenic agent declared by the World Health Organization. Human genetic variability may account for the variability in the clinical outcome of HHV-8 infection. Dr. Jackson aims to discover novel genetic alterations underlying childhood KS and to understand how specific gene defects drive KS in conjunction with HHV-8. This work will identify molecular pathways of impaired antiviral immunity or tumor suppression, consequently broadening our understanding of virus-driven cancers. The genetic study of KS in childhood may provide new insights into the pathogenesis of KS, and aid in developing potential future therapeutics. It will also benefit children at risk of KS in regions of the world where the prevalence of HHV-8 is high.. ...
