We have previously identified and characterized a monoclonal antibody (McAb 302) with potent passive protective activity in mice infected with Plasmodium yoelii, a murine malarial parasite which depends on antibodies for resolution. To further study the appearance and regulation of this antibody during infection, we prepared syngeneic monoclonal antibodies specific for idiotopes present on McAb 302. Three hybridomas were established which synthesized antibodies that bound only to the homologous idiotype but which did not recognize isotypic specificities. All three of these antibodies were found to recognize distinct 302 idiotopes and two of these were shown to be specific for determinants associated with the antibody combining site of McAb 302. One of these monoclonal anti-idiotypic antibodies was used to develop an enzyme-linked immunosorbent assay for the 302 idiotype. When serum samples taken at different times from mice undergoing a primary infection with P. yoelii were tested in this assay, the 302 idiotype could not be detected even though the host was mounting a significant humoral response to the 230-kDa antigen recognized by McAb 302. These studies suggest that the idiotype of the protective McAb 302 is not a predominant one involved in the resolution of a P. yoelii infection and that only some idiotypes of antibodies directed to relevant plasmodial antigens possess significant biological activity. Therefore, protective immunization with plasmodial antigens may require the elicitation of selected idiotypes. Attempts to alter the course of P. yoelii infection by preimmunization with monoclonal or polyclonal anti-idiotypic reagents were unsuccessful.
