Abstract excerpt
We have previously demonstrated that 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) suppressed the induction of the costimulatory molecule CD86 (B7-2) on B220+ and Mac-1+ spleen cells following the injection of allogeneic P815 tumor cells. In this study, TCDD exposure was shown to suppress CD54 and major histocompatibility complex (MHC) class II expression on B220+, Mac-1+, and CD11c+ splenic antigen presenting cells...
