The kinetics of Staphylococcal enterotoxin B-(SEB) induced peripheral tolerance has been investigated. Ten days after SEB injection, thymectomized BALB/cByJ mice showed suppressed spleen cell proliferative responses to SEB. After 2 mo the SEB-specific response was partly recovered. Four months later the response of spleen cells of SEB-primed mice was comparable to those of control mice. The proportion of CD4+, V beta 8+ T cells was diminished in the tolerized mice and was not restored even after the response was recovered. Purified CD4+, V beta 8+ T cells from SEB-primed mice after 4 mo responded similarly to SEB as control CD4+, V beta 8+ T cells. These expressed a similar profile of surface markers compared with that of unprimed control cells, except a homing receptor was slightly lower. An experiment that addressed the possibility that non-anergic T cells expand over time and are in fact responsible for the recovery of the proliferative response showed that such events unlikely occur in vivo. Therefore, the data indicate that T cell anergy is reversible in vivo. It is also suggested that the challenge with superantigen results in neither clonal expansion nor specific CD4+, V beta 8+ T cell memory.
