PD-L1 blocking fails to alter the regulatory molecules in splenic B-cell during infection. a Overlay of representative histograms show PD-L1 expression in splenic CD19⁺ B cells. Representative dot plots show the expression of CD5 (b), IFN-γ, IL-10 and TGF-β (c) in splenic CD19⁺ B cells. Bar graphs indicate the results from one of two independent experiments with ≥ 5 mice in each group. *P < 0.05, **P < 0.01
