Elucidating the cellular and molecular basis of naturally acquired immunity to Plasmodium falciparum infection would assist in developing a rationally based malaria vaccine. Innate, intermediate, and adaptive immune mechanisms are all likely to contribute to immunity. Interferon-gamma (IFN-gamma) has been implicated in both protection against and the pathogenesis of malaria in humans. In addition, considerable heterogeneity exists among rapid IFN-gamma responses to P. falciparum in malaria-naive donors. The question remains whether similar heterogeneity is observed in malaria-exposed individuals and whether high, medium, or low IFN-gamma responsiveness is differentially associated with protective immunity or morbidity.
