Figure Lengend Snippet: Abrogation of signaling downstream of the BCRs and of CXCR4 and CXCR5 receptors. Displayed are immunoblots from CLL cells from 1 representative patient of 9 patients, that were either unstimulated or stimulated for 10 minutes with anti-IgM (αIgM,

Article Snippet: To determine the efficacy of the inhibitor to antagonize BCR-derived prosurvival signals after BCR triggering with anti-IgM, CLL samples (107 cells/mL) were preincubated in complete RPMI medium with or without PCI-32765 for 30 minutes at 37°C, and then stimulated by the addition of 10 μg/mL anti-IgM (polyclonal goat F(ab′)2 fragments to human IgM; MP Biomedicals).
