Low CD40 surface expression on circulating IgM+λ+CD38high cells during KSHV-MCD flare. MFI is normalized on isotype MFI (MFI = CD40 MFI-isotype MFI) and expressed for KIV, conventional plasmablasts, and B and T cells. Median values and IQRs are represented for each plot. ∗∗∗∗P < .0001, Mann-Whitney U test.
