The mechanisms involved in the maintenance of staphylococcal enterotoxin B
(SEB)-induced T cell anergy are poorly understood. Here, we demonstrate
that CD4+ T cell anergy induced by SEB treatment is under partial B cell
control. This effect is not mediated by anti-SEB antibodies or any in vitro
B cell-produced suppresser factor. At day 13 after SEB immunization, T
cells from B cell-deficient mice proliferate upon in vitro stimulation with
SEB. These results suggest that SEB- induced T cell anergy is reversible
and that B cells have an important function in anergy maintenance in CD4+ T
cells, both in vivo and in vitro.
