Surface expression of costimulatory molecules on KIV, conventional plasmablasts, KSHV+EBV− BCP1 cell line, and EBV+ LCL. Histograms represent the percentage of CD40+, CD70+, CD86+, CD137L+, OX40-L+, BAFF-R+, ICOS-L+, and PD-L1+ cells among KIV, conventional plasmablasts, KSHV+EBV− BCP1 cell line and EBV+ LCL. The number of samples tested for each marker is detailed in the manuscript. ∗P < .05, Mann-Whitney U test.
