title: Regulation of IgM expression by adjuvant activated splenic suppressor T cells.
abstract: Adjuvant-activated Lyt-2 positive suppressor T cells (Ts) are able to inhibit the expression of IgM plaque-forming cells (PFC) during a primary in vitro response to sheep red blood cells. Under the same experimental conditions these suppressor T cells do not affect a secondary IgM PFC response against SRBC. Activated Ts cells were also found to suppress the spontaneous IgM secretion of cultured B cells as well as the IgM production of B cells stimulated by lipopolysaccharide or by supernatant from a T-helper-cell clone.
