| risk factors for idiopathic cerebellar ataxia of late onset. | in an attempt to identify risk factors for the development of idiopathic cerebellar ataxia (idca) we performed a case-control study of 59 idca patients. hypertension and medicine intake were less frequent in idca than in neurological controls. multiple logistic regression yielded an odds ratio (or) for hypertension of 0.13 (95% confidence interval: 0.00-1.02, p=0.0527) and medicine intake of 0.10 (95% confidence interval: 0.00-0.72, p=0.0157). in contrast, we did not identify an association of i ... | 1998 | 9849801 |
| varicella-zoster virus glycoprotein ge: endocytosis and trafficking of the fc receptor. | varicella-zoster virus (vzv) encodes a functional cell membrane fc receptor called glycoprotein ge. vzv ge resembles other mammalian cell membrane receptors, such as the mammalian fc receptor. in further analyses by transient transfection, the cellular trafficking of vzv ge was compared to other cell surface receptors. vzv ge was shown to undergo endocytosis from the cell membrane when visualized by laser scanning confocal microscopy. the endocytosis and trafficking pathway of vzv ge followed cl ... | 1998 | 9852964 |
| intracellular transport of varicella-zoster glycoproteins. | previous observations have established that varicella-zoster virus (vzv) is enveloped in the trans-golgi network (tgn) in cultures infected with vzv and that the glycoprotein ge is targeted to the tgn by a signal sequence (ayrv) and an acidic tgn signal patch in its cytosolic domain. neither sequence is present in other vzv glycoproteins. like ge, gi was targeted to the tgn when it was expressed in transfected cells, suggesting that gi also contains tgn targeting information (colocalized with ge ... | 1998 | 9852965 |
| regulated nuclear localization of the varicella-zoster virus major regulatory protein, ie62. | the major transcriptional regulatory protein encoded by varicella-zoster virus (vzv), ie62, accumulates within the nucleus of transfected and vzv-infected cells. data are presented to show that nuclear localization of ie62 is dependent upon charged amino acids mapping to residues 677-685 of the 1310 residue protein. furthermore, coexpression of vzv open-reading frame (orf) 66 with ie62 results in the accumulation of cytoplasmic forms of ie62, suggesting that the orf 66 protein can override the i ... | 1998 | 9852967 |
| the varicella-zoster virus (vzv) open-reading frame 29 protein acts as a modulator of a late vzv gene promoter. | transient expression assays have shown that the varicella-zoster virus (vzv) open-reading frame (orf) 29 gene product can act as a modulator of vzv gene expression. the orf 29 protein alone does not appear to have any effect on transcription; however, in its presence, changes in the level of reporter gene activity mediated by the vzv immediate early (ie) 62 major transactivator are seen. increased expression was observed in human fibroblasts, mewo cells, hela cells, and t cells. in contrast, the ... | 1998 | 9852970 |
| evidence of latent varicella-zoster virus in rat dorsal root ganglia. | latent varicella-zoster virus (vzv) was studied in ganglia of rats that had been inoculated subcutaneously with either a high-passaged wild-type, a low-passaged wild-type, or the vaccine strain of virus using in situ hybridization. nine of 11 rats injected with virus and no control rats developed serum vzv antibodies as demonstrated by fluorescent antibody membrane antigen. polymerase chain reaction 2 weeks following inoculation did not detect viremia in the rats. vzv was detected by in situ hyb ... | 1998 | 9852973 |
| cytokine production in varicella-zoster virus-stimulated cultures of human blood lymphocytes. | estimates of responder cell frequency (rcf) based on limiting dilution analyses are laborious, and alternative means to quantitate cell-mediated immunity to immunogens are desirable. it was shown that levels of interleukin (il)-2 in the supernatant of varicella-zoster virus-stimulated blood lymphocytes from immune adults peaked at 48 h of culture and correlated partially with estimates of rcf (r = .74, p = .003). levels of gamma-interferon, il-4, and il-10 increased through the first 4 days of c ... | 1998 | 9852984 |
| a dose-response study of a live attenuated varicella-zoster virus (oka strain) vaccine administered to adults 55 years of age and older. | decreased cell-mediated immune (cmi) response to varicella-zoster virus (vzv) is correlated with an increased risk of reactivation of latent virus from dorsal root sites, leading to herpes zoster. the cell-mediated and humoral immunogenicity of three concentrations (3200, 8500, and 41,650 pfu/dose) of a live attenuated vzv vaccine (oka strain; vzv/oka) was compared with a control pneumococcal polysaccharide vaccine in 200 healthy adults who were > or = 55 years old. six weeks after vaccination, ... | 1998 | 9852985 |
| use of a live attenuated varicella vaccine to boost varicella-specific immune responses in seropositive people 55 years of age and older: duration of booster effect. | varicella-zoster virus (vzv)-specific t cell immunity was measured in 130 persons > or = 55 years of age 6 years after they received a live attenuated vzv vaccine. circulating t cells, which proliferated in vitro in response to vzv antigen, were enumerated (vzv responder cell frequency assay). six years after the booster vaccination, the vzv-responding cell frequency (1/61,000 circulating cells) was still significantly (p < .05) improved over the baseline measurements (1/70,000) and appears to h ... | 1998 | 9852987 |
| comparison of primary sensitization of naive human t cells to varicella-zoster virus peptides by dendritic cells in vitro with responses elicited in vivo by varicella vaccination. | dendritic cells (dc) are potent apc during primary and secondary immune responses. the first objective of this study was to determine whether human dc mediate in vitro sensitization of naive cd4+ t cells to epitopes of the immediate early 62 (ie62) protein of varicella zoster virus (vzv). the induction of cd4+ t cell proliferative responses to eight synthetic peptides representing amino acid sequences of the vzv ie62 protein was assessed using t cells and dc from vzv-susceptible donors. the seco ... | 1999 | 9886433 |
| gray-white, spherical deposition on retinal vessel associated with acute retinal necrosis and diabetic retinopathy in htlv-i carriers. | tiny, gray-white, spherical deposits were found on the retinal vessels and vitreoretinal interface of the fovea in a 55-year-old woman with acute retinal necrosis due to varicella-zoster virus, and in a 47-year-old man with preproliferative diabetic retinopathy. both patients developed massive vitreous opacities due to uveal inflammation or hemorrhages that rendered the fundus difficult to visualize. a therapeutic vitrectomy revealed gray-white, tiny spherical deposits, about blood-vessel-diamet ... | 1998 | 9886741 |
| detection of serum antibodies against cytomegalovirus, varicella zoster virus and human herpesvirus 6 in patients with recurrent aphthous stomatitis. | there has recently been renewed interest in the possible role of viruses in recurrent aphthous stomatitis (ras). in this study, sera from 22 patients with ras, 24 patients with oral lichen planus (olp) and 15 healthy controls were screened for igg and igm class antibodies to human cytomegalovirus (hcmv), varicella zoster virus (vzv) and human herpesvirus 6 (hhv-6). commercially available elisa and immunofluorescence kits were employed. there were no significant differences in the prevalence of i ... | 1999 | 9890451 |
