Cancer cells can evade clearance by macrophages through overexpression of antiphagocytic surface proteins including CD47 [30], programmed cell death ligand 1 (PD-L1) [31], the beta-2 microglobulin subunit of the major histocompatibility class I complex (B2M) [32], and CD24 [7]. The gene discussed is CD274; the disease is cancer.
