Conclusions: The data suggest that activation of B cells from SLE patients require CD40/CD40L interaction to increase PD-L1 expression, which is, however, reduced compared to HD. Diminished PD-L1 expression upon B cell stimulation is consistent with impaired inhibition of T cells in SLE (figure 1). REFERENCES: [1] Nishimura H, et al.
