Identifying Correlates of Anti-Parasite Immunity to Malaria in Infants and Adults: A Systems-Based Approach

Isaac Sseswanyana of the Infectious Diseases Research Collaboration in Uganda will investigate natural anti-parasite immunity to malaria to guide the development of improved malaria vaccines and therapeutics. Natural anti-parasite immunity is observed in malaria endemic regions in adults and infants who control parasitemia at low levels without developing symptoms, in the latter group likely due at least in part to the transfer of effective maternal antibodies. They will use existing samples from two longitudinal studies in Uganda to test the hypothesis that the repertoires, biophysical properties, and functional features of Plasmodium falciparum-specific antibodies are determinants of this natural immunity. They will also identify and characterize malaria-specific T cells that correlate with anti-parasite immunity and focus on evaluating cellular or proteomic predictors of durable anti-parasite antibodies.
