prevalence of herpesviridae and hepatitis b virus dna in the liver of patients with non-a, non-b fulminant hepatic failure. | members of the herpes virus family and hepatitis b virus (hbv) have been implicated as etiologic agents in non-a, non-b (nanb) fulminant hepatic failure (fhf), but the frequency of infection with these agents has not been established using appropriate controls. to examine this issue, we studied 50 nanb fhf patients and 104 liver transplant recipients from north america and europe. hepatic dna was analyzed by polymerase chain reaction (pcr) for evidence of epstein-barr virus (ebv), cytomegaloviru ... | 1996 | 8938162 |
a tyrosine-based motif and a casein kinase ii phosphorylation site regulate the intracellular trafficking of the varicella-zoster virus glycoprotein i, a protein localized in the trans-golgi network. | we have studied the intracellular trafficking of the envelope glycoprotein i (gpi) of the varicella-zoster virus, a human herpes virus whose assembly is believed to occur in the trans-golgi network (tgn) and/or in endocytic compartments. when expressed in hela cells in the absence of additional virally encoded factors, this type-i membrane protein localizes to the tgn and cycles between this compartment and the cell surface. the expression of gpi promotes the recruitment of the ap-1 golgi-specif ... | 1996 | 8947032 |
[retinal manifestations of aids]. | cytomegalovirus (cmv) retinitis is the most common retinal opportunistic infection in aids patients and is the main cause of blindness. it is generally associated with a cd4+ lymphocyte count below 50/microl. cmv retinitis is often asymptomatic (54% of the cases), frequent ophtalmoscopic screening is very important. two virostatic drugs (cymevan and foscavir) have been approved for the treatment of cmv retinitis. both are effective in preventing the progression of the lesion within 3 weeks of in ... | 1996 | 8949282 |

cloning and sequence analysis of a marek's disease virus origin binding protein (obp) reveals strict conservation of structural motifs among obps of divergent alphaherpesviruses. | marek's disease virus (mdv) is a highly cell-associated avian herpesvirus. in its natural host, mdv induces marek's disease (md), a lethal condition characterized by malignant lymphoma of t cells. although symptoms of md may be prevented by vaccination, no practical pharmacological method of control has been widely accepted. viral replication represents a point at which pharmacological control of herpesvirus infection may be most successful. however, this requires detailed knowledge of viral rep ... | 1996 | 8972568 |
varicella-zoster virus fc receptor ge glycoprotein: serine/threonine and tyrosine phosphorylation of monomeric and dimeric forms. | varicella-zoster virus (vzv) glycoprotein ge is the predominant viral cell surface molecule; it behaves as an fc receptor for immunoglobulin g, but its central function may be more closely related to viral egress and cell-to-cell spread. to further analyze the receptor properties of vzv ge, the ge gene (also called open reading frame 68) was expressed by a baculovirus vector in insect cells. the recombinant baculovirus ge product had a molecular mass of 64 kda, smaller than the previously docume ... | 1997 | 8985329 |

chaperone functions common to nonhomologous epstein-barr virus gl and varicella-zoster virus gl proteins. | herpesviruses encode the complex-forming, essential glycoproteins gh and gl. maturation and transport of gh are dependent on coexpression of its chaperone, gl. the gl proteins of alpha herpesviruses and gamma herpesviruses do not have a significant percentage of amino acid sequence homology. yet, as we report herein, the diverse gl glycoproteins of epstein-barr virus (ebv) and varicella-zoster virus (vzv) were functionally interchangeable, although membrane expression and maturation of gh were s ... | 1997 | 8995697 |
comparison of specific immunities to varicella-zoster virus following post-exposure prophylaxis of varicella by oral acyclovir observed in a family. | an otherwise healthy 3-year-old girl developed severe varicella complicated by aseptic meningitis and received intravenous acyclovir (acv) therapy. her two siblings who were susceptible to varicella-zoster virus (vzv) and closely exposed to vzv in the family received oral acv (45 or 54 mg/kg per day in four divided doses for 7 days) starting 8 days after onset of the index case for post-exposure prophylaxis of varicella. they showed only five or seven papules over the body without fever 12 days ... | 1996 | 9002312 |
replacement of the herpes simplex virus type 1 vmw175 dna binding domain with its varicella-zoster virus counterpart results in a protein with novel regulatory properties that can support virus growth. | the alphaherpesviruses encode major immediate early transactivator proteins that are essential for the expression of later classes of viral genes. we have previously shown that the extensive sequence similarity between the herpes simplex virus type 1 (hsv-1) and varicella-zoster virus (vzv) members of the family (proteins vmw175 and vzv140k) extends to function, since a virus which expresses vzv140k in place of vmw175 is able to grow, albeit at reduced efficiency. we have also shown that the dna ... | 1997 | 9010302 |
