IFNG and malaria: Consistent with the Th1-skewed cytokine response that febrile malaria induces, we found that Th1-cytokine-containing supernatants of iRBC-stimulated PBMCs plus BCR crosslinking induced T-bet expression in naïve B cells, a response that was abrogated by neutralizing IFN-γ or blocking the IFN-γ receptor.
