CD47 and neoplasm: Along with signals such as CRT, whichrecruit cells that exhibit phagocytic activity, tumor cells can displaymolecules that are antagonistic to "eat-me" signals (CD47 molecules) on theirsurface, resulting in the suppression of calreticulin-mediated phagocytosis.The interaction between CD47 and the SIRPα receptor on dendritic cells isa signal that inhibit phagocytosis [112].
