CD8A and dengue disease: Data stratified by patient BMI status and disease severity shows similar frequencies of activated and GzmB+ CD8+ T-cells in HW and OW/OB patients, but a trend towards increasingly higher PD-1 expression levels from non-SD HW, non-SD OW/OB, SD HW and SD OW/OB patients at both time points, suggesting that in dengue PD-1 expression in CD8+ T-cells may be exacerbated by high BMI (Fig. 3f, g).
