pubmed:abstractText |
Intracranial (i.c.) infection of immunocompetent mice with lymphocytic choriomeningitis virus (LCMV) results in immunopathological lethal meningitis mediated by CD8+ cytotoxic T lymphocytes (CTL). Vaccination of immunocompetent mice elicits a CD8+ CTL response that can protect the mice from lethal meningitis. beta 2 microglobulin-deficient (beta 2m-/-) mice are deficient in CD8+ CTL, exhibit CD4+ CTL, and, after i.c. LCMV infection, undergo a less severe meningitis with decreased mortality and additionally develop a wasting disease. Both wasting disease and mortality in beta 2m-/- mice are mediated by CD4+ T cells. We studied the effects of vaccination and challenge dose on weight loss, mortality and viral clearance after i.c. LCMV infection in beta 2m-/- mice. Unvaccinated beta 2m-/- mice had significant weight loss and mortality at doses of 200 and 10(3) p.f.u. LCMV, while a dose of 10(6) p.f.u. LCMV elicited significant mortality but less weight loss. Vaccination with u.v.-inactivated LCMV in complete Freund's adjuvant or with vaccinia virus expressing the LCMV glycoprotein or nucleoprotein genes protected beta 2m-/- mice from mortality but not weight loss after 200 p.f.u. LCMV challenge. Although protected from mortality, beta 2m-/- mice were unable to clear LCMV from their brains or spleens. Therefore, we show that vaccination can protect against lethal immune-meningitis in the face of persistent infection.
