Adoptive transfer of allotype-specific suppressor cells inhibits thymus- independent immunoglobulin production in syngeneic athymic mice
EB Jacobson
(SJL X BALB)F1 suppressed mice have, in their lymphoid tissues, a
population of suppressor T cells directed specifically against a paternal
gamma G2a allotype (Ig-1b). Spleen or lymph node cells from these mice were
injected into syngeneic nude mice and the effect on thymus-independent
synthesis of Ig-1b in the athymic recipients was determined. After the
injection of suppressor cells, Ig-1b disappeared from the serum of the
recipients in a time course similar to that seen in normal mice. These
results indicate that suppression occurs in the absence of thymus-derived
helper cells, and they suggest that Ig-1b- producing B cells are the target
of allotype-suppressor cells.
