[the geographical spread of enterovirus uveitis in the ussr].enteroviral uveitis is accompanied by intensive and long-term production of specific neutralizing antibodies. the antibody titer to the causative virus echo 19/k (siberia, krasnoyarsk, 1980-1981) was 1:1000-1:65,000 in 80% of children 5 to 6 1/2 years after the illness. in retrospective examinations of blood sera from children with the history of uveitis using a neutralization test with ophthalmotropic strains of echo 19 and echo 11 viruses, the echo-virus etiology of this disease was first esta ...19902256316
interferon-sensitive coxsackievirus variants in nature.variants of a clinical isolate of coxsackie b-4 virus that differ in interferon (ifn) sensitivity were selected from virus stock both before and after passage in mice. ifn sensitivity was a stable property on subsequent plaque selection. the ifn-sensitive variant was less virulent than its ifn-insensitive counterpart, whether from the original virus stock or from mouse passaged virus. none of these variants was diabetogenic in mice. these studies demonstrate that coxsackievirus variants of diffe ...19852409191
t lymphocyte responses to coxsackie b4 and mumps virus. ii. immunoregulation by hla-dr3 and -dr4 associated restriction elements.a major part of the t lymphocyte response to mumps and coxsackie b4 virus appears to be restricted by hla-dr associated restriction elements. this was further corroborated in inhibition experiments using monoclonal antibodies reactive with different hla class ii molecules. only antibodies reactive with dr molecules significantly inhibited the response. the frequencies of dr restricted antigen-reactive t lymphocytes (artl) to mumps and coxsackie b4 virus were then investigated, using a limiting d ...19852413585
characterization of an echovirus type 30 variant isolated from patients with aseptic meningitis.an outbreak of echovirus type 30 infection associated with aseptic meningitis occurred among newborn babies in a hospital neonatal room at fukui city in 1983. the isolated virus was identified as an antigenic variant of echovirus type 30 by cross-neutralization tests with antisera against the prototype bastianni strain and the present isolate. western blot analysis demonstrated that the antigenic determinants responsible for virus neutralization, some of which were type specific and others strai ...19862425228
humoral immunity against viral antigens in type 1 diabetes: altered iga-class immune response against coxsackie b4 virus.a group of 210 pediatric type 1 diabetic patients with long duration of illness and their matched controls (age range 2-19 years) were analysed for coxsackie b4 antibodies in igg-, igm- and iga-antibody classes by enzyme-linked immunosorbent assay (elisa). about 60% of both patients and controls were seropositive. however, patients had higher prevalence and mean levels of iga-class antibodies compared to controls. no such difference was found in igg- or igm-antibody classes. the elevation of iga ...19862426921
antigen-specific suppressor t cells prevent cardiac injury in balb/c mice infected with a nonmyocarditic variant of coxsackievirus group b, type 3.two variants of coxsackievirus group b, type 3 (cvb3o and cvb3m) infect balb/c cardiac tissue equally, but only one variant (cvb3m) induces myocarditis. various studies indicate that disease resistance in cvb3o-infected mice results from generation of suppressor cells. low-dose cyclophosphamide (50 mg/kg body weight) treatment enhances inflammation in both cvb3m and cvb3o-infected animals, which clearly demonstrates that cvb3o has the capacity to induce disease, but inhibitory factors must exist ...19862432792
coxsackievirus b-3-induced myocarditis. virus and actinomycin d treatment of myocytes induces novel antigens recognized by cytolytic t lymphocytes.balb/c mice inoculated with 6 x 10(4) plaque-forming units of a myocarditic variant of coxsackievirus, group b, type 3 (cvb3m) developed three distinct ctl populations recognizing putative virion (virus specific ctl, vctl), normally expressed heart (autoreactive ctl, actl), and aberrant metabolic (mctl) ag. induction of the mctl-specific ag on cardiocytes correlated with the ability of the myocarditic viruses and actinomycin d to interfere with cellular metabolism as measured by 3h-uridine and 3 ...19882459248
intracellular detection of sense and antisense enteroviral rna by in situ hybridization.we prepared sense (s) and anti-sense (as) 3h-labelled single-stranded rna probes by polymerase-directed in vitro transcription of a coxsackievirus b3-derived cdna fragment cloned in the pgem2 plasmid vector. the probes detected, by in situ hybridization, both s and as forms of viral rna in the cytoplasm of coxsackievirus-infected tissue culture cells. more s (genomic and messenger) rna was present than as (negative and replicative intermediate) rna. we confirmed and quantitated this observation ...19882464608
murine cell-mediated immune response recognizes an enterovirus group-specific antigen(s).splenocytes taken from mice inoculated with coxsackievirus b3 (cvb3) (nancy) developed an in vitro proliferative response against cvb3 antigen. this response could not be detected earlier than 8 days postinoculation but could be detected up to 28 days after exposure to cb3. cvb3-sensitized splenocytes responded not only to the cvb3 antigen but to other enteroviruses as well. this response was found to be enterovirus specific in that no response was detected to a non-enteroviral picornavirus, enc ...19892476566
