SELL and malaria: We compared frequencies of B cell subsets expressing markers of activation and co-stimulation (IgG, IgM, b220, CD40, CD150, CD80, and CD86), inhibition (PD1, CD95, and TACI) and migration (CD62L, CXCR3, CCR3, and CD71) between malaria-exposed and non-exposed individuals (Table 3; Table S2 in Supplementary Material) and between different categories of exposure and non-exposed (Figure 3).
