B Cell Receptor and CD40 Signaling Are Rewired for Synergistic Induction of the c-Myc Transcription Factor in Germinal Center B Cells

Luo et al. show that CD40 and BCR signaling in GC B cells is rewired to control very different pathways, and both signals are required for optimal induction of c-Myc, suggesting a mechanism of signaling-directed positive selection of GC B cells.
