For example, tumor cells release EVs containing programmed death‐ligand 1 (PD‐L1, expressed on cancer cells) on their surface, and these EVs inhibit the function of CD8 T cells by binding to programmed death‐1 (PD‐1, expressed on immune cells) on T cells and promote the immune escape of tumor cells.52 The gene discussed is CD274; the disease is neoplasm.
