Abstract: IFN-gamma-driven responses to malaria have been shown to modulate the development and function of T follicular helper (TFH) cells and memory B cells (MBCs), with conflicting evidence in their involvement in the induction of antibody responses required to achieve clinical immunity and their association with disease outcomes. Using high-dimensional single cell mass cytometry, we identified distinct populations of TH1-polarized CD4+ T cells and MBCs expressing the TH1-defining transcription factor T-bet, associated with either increased or reduced risk of Plasmodium vivax malaria, demonstrating that inflammatory responses to malaria are not universally detrimental for infection. Furthermore, we found that whereas class-switched but not IgM+ MBCs were associated with reduced risk of symptomatic malaria, populations of TH1 cells with a stem central memory phenotype, TH17 cells and T regulatory cells were associated with protection from asymptomatic infection, suggesting that activation of cell mediated immunity might be also required to control persistent P. vivax infection of low parasite burden.
