We examined the effects of the developmental milieu on the capacity of B cells to undergo immune response gene-controlled, T cell-dependent polyclonal proliferation. Although I-Aq poly(Glu60 Ala30 Tyr10)n (GAT)- nonresponder T cells developing in a responder environment become phenotypic GAT-responders, I-Aq B cells remain unresponsive to GAT, even after maturation in a GAT-responder animal. Conversely, (B10.A x B10.Q)F1 ([GAT responder x GAT nonresponder]F1) T cells developing in a B10.Q GAT nonresponder host fail to respond to GAT, but F1 B cells from the same F1 leads to parent chimeras make excellent proliferative responses in the presence of GAT and responder T cells. Thus, by this assay, B cell immune response gene function is genetically determined and is not affected by the developmental milieu.
