Feedback suppression of the primary humoral immune response to sheep erythrocytes (SRBC) in vitro was induced with cell-free supernate material derived from antigen-(SRBC) activated B (sIg+) cells. This soluble products bears Ig determinants and binds to the eliciting antigen (SRBC). The activity of this antibody in suppressing anti-SRBC plaque-forming cell responses is restricted to spleen cell cultures containing B cells sharing VH genes with the B cells producing the suppressive antibody. The anti-hapten (trinitrophenyl) response to derivatized SRBC is not affected by antigen-primed B cells or their products. These data are compatible with suppression being mediated by anti-antigen antibody, either (a) via blockade of different SRBC epitopes recognized by a limited set of B cell clones in each mouse strain, (b) via triggering of an anti-idiotypic response, either antibody or suppressor T cell in nature, restricted to activity in cultures containing B cells sharing VH structures with the original antibody, or (c) via interference by preformed antibody with T cell help directed at idiotype bearing B cells.

CLAIMS
- The anti-hapten response to derivatized SRBC is not affected, and the findings are compatible with suppression by anti-antigen antibody through epitope blockade, anti-idiotypic effects, or interference with T cell help to idiotype-bearing B cells.박진우 (dztg5apj7m) extractionB (s683577b42) reviewKiller Whale (322360f1c1) reviewAK (4715169a40) review
- The suppressive activity carries Ig determinants, binds the eliciting SRBC antigen, and is restricted to cultures containing B cells that share VH genes with the B cells producing the suppressive antibody.박진우 (dztg5apj7m) extractionB (s683577b42) reviewKiller Whale (322360f1c1) reviewAK (4715169a40) review
