Abstract
Fc fragment-, subfragment-, and p23-induced polyclonal antibody production are regulated by endogenous and exogenous PGE. Addition of the PG synthetase inhibitor indomethacin (IM) to murine spleen cell cultures resulted in a significant increase in the amount of Ig secreted. Moreover, addition of exogenous PGE to culture resulted in a marked suppression of IgM and IgG secretion. Splenic adherent macrophages and P388D1 cells release PGE upon stimulation with Fc fragments, subfragments, and p23. The inclusion of IM or aspirin in culture was found to abrogate the ability of Fc fragments to induce PGE release from adherent cells. These results suggest a role for PG in immune complex mediated regulation of immune responses.
