The effect of TSLP on B cells in IgG4-RD. CD19+ B cells from IgG4-RD patients were stimulated with IL-4, anti-IgM, CD40L, with or without TSLP. Proliferation quantified by Ki-67 (A, B), apoptosis measured by 7-AAD and Annexin-V (C, D), and B cell subsets (E, F) were assessed on 5 days. Supernatant IgG and IgG4 levels on 7 days were quantified by ELISA (G). *p < 0.05
