For instance, chimeric antigen receptors (CAR) recognising specific antigens on tumour cells have been added in GM-CSF-differentiated patient macrophages (CT-0508 against HER2) or monocytes (CT-0525 against HER2, MT-101 against CD5) to enhance cancer cell phagocytosis [183, 184]. Here, ERBB2 is linked to neoplasm.
