WebPediatric Research - Signaling functions of the CD40 Receptor - CD40 Ligand (gp39) pair♦ 39 WebIgE synthesis by B cells requires two signals. The first signal is delivered by the cytokines IL-4 or IL-13, which target the Cϵ gene for switch recombination. The second signal is delivered by interaction of the B cell surface antigen CD40 with its ligand (CD40L) expressed on activated T cells. This activates deletional switch recombination.
