Guinea pig spleen cells cultured together with peritoneal exudate lymphocytes (PEL) were found to generate large numbers of antibody-forming cells (AFC) in vitro in response to hapten-protein antigens. Neither cell type cultured alone yielded appreciable responses. Strain 13 or F1 (Strain 2 X Strain 13) lymphocytes, but not those from strain 2 animals, are able to respond to the genetically controlled antigen, DNP-guinea pig albumin (DNP-GPA). Antisera directed against responder (strain 13) parent Ia antigens selectively blocked the generation of AFC by F1 (strain 2 X strain 13) spleen-PEL mixtures in response to DNP-GPA. Both allogeneic (strain 2) and syngeneic macrophages functioned equally well in presentation of DNP-GPA to strain 13 lymphocytes.
