Chronic immune activation from persistent malaria infections can induce immunophenotypic changes associated with T cell exhaustion. However, associations between T and B cells during chronic exposure remain undefined. We analyzed peripheral blood mononuclear cells from malaria-exposed pregnant women from Papua New Guinea and Spanish malaria-naïve individuals using flow cytometry to profile T cell exhaustion markers phenotypically. T cell lineage (CD3, CD4, CD8), inhibitory (PD1, TIM3, LAG3, CTLA4, 2B4) and senescence (CD28-) markers were assessed...
