ER stress effects on germinal center B- and plasma-cell markers. Gene expression of plasma cell markers Blimp1, CD138, and BCL6 were evaluated by real-time qPCR. LCLs were treated with TG and SAL for 1 hour (A), 3 hours (B), or 6 hours (C) before gene expression of plasma cell markers was evaluated by real-time qPCR. (D) LCLs were treated with TG and SAL as described and plasma cell markers were evaluated at 72 hours after drug treatment by real-time qPCR.
