    Depiction of CD47/SIRPα signaling pathway. CD47 is overexpressed on the surface of cancer cells, acting as a “don’t eat me” signal. SIRPα is a receptor on the surface of macrophages and dendritic cells. When CD47 binds to SIRPα, it sends an inhibitory signal to the myeloid cells. This interaction inhibits the phagocytic activity of the myeloid cells, preventing them from engulfing and destroying cancer cells, thus allowing the cancer cells to evade the immune system.

    Prerequisites for macropage activation. In a normal situation, CD47 binds to SIRPα, acting as the “don’t eat me” signal, and no “eat me” signal is present. Therefore, there is no or poor macrophage activation (A) . When only CD47 is blocked, the “don’t eat me” signal is inhibited. However, no “eat me” signal is activated, resulting in only limited macrophage activation (B) . When the CD47 “don’t eat me” signal is present, and only the Fc-receptor “eat me” signal is activated, there is still only limited macrophage activation (C) . When both CD47 is blocked and the Fc-receptor “eat me” signal is activated, full macrophage activation occurs (D) .

    Depiction of CD47/SIRPα signaling pathway. CD47 is overexpressed on the surface of cancer cells, acting as a “don’t eat me” signal. SIRPα is a receptor on the surface of macrophages and dendritic cells. When CD47 binds to SIRPα, it sends an inhibitory signal to the myeloid cells. This interaction inhibits the phagocytic activity of the myeloid cells, preventing them from engulfing and destroying cancer cells, thus allowing the cancer cells to evade the immune system.
