More recently, it has been suggested a mechanism called “trogocytosis”, where fragments of the plasma membrane carrying antigen–antibody complexes, together with other parts of cell membrane (CD49d, CD56, CD138, CD54, and CD44) are transferred by monocytes and granulocytes, in the absence of evident phagocytosis of tumor cells [44]. This evidence concerns the gene SDC1 and neoplasm.
