FCGR2A and cancer: The mechanisms of monocyte mediated shaving/trogocytosis are not well established but appear to involve a receptor-mediated endocytotic process where the plasma membranes of the monocyte and cancer cell fuse at the site of FcγR-Ab binding, and the opzonizing Ab and its target are removed from the cancer cell, along with parts of the cancer cell's plasma membrane [27], [29], [58].
