Lymphocytic choriomeningitis virus (LCMV)-induced increase in sTNF-R75 levels in serum (a), as well as in production of TNF-α and nitric oxide (NO) by splenic adherent cells in vitro (b), is T cell-dependent. LCMV-infected (inf.) T cell-deficient (nu/nu) mice and wild-type (+/+) mice were killed 8 days post-infection together with uninfected control mice (con.) from both groups. Points represent individual mice, and bars are means ± s.e.m. of groups.
