Antigen receptor-mediated B cell death is blocked by signaling via
B cells may thus be protected from death by interaction with T cells during antibody responses to T cell-dependent (TD) antigens Moreover, the type 1 T cell-independent (TI-1) antigen LPS is capable of blocking sig-mediated death of a B cell line (18) and may activate B cells even in the absence of T cells
