Correlations between CD100^hi on CD19⁺ cells and PD-1 and PD-L1 on T cells.

(A) Correlations between frequencies of CD100hi on CD19+ cells and frequencies of PD-1 on CD4+ T cells and on CD8+ T cells. (B) Correlations between frequencies of CD100hi on CD19+ cells and frequencies of PD-L1 on CD4+ T cells and on CD8+ T cells. Correlations were determined by Spearman’s rank correlation. * = p<0.05 when comparing conditions. Each symbol corresponds to an individual.
