CD8A and neoplasm: This antibody‐activated cytotoxic T‐cell immune response is responsible for long‐term tumor eradication, at least in mouse models.[21] Also, tertiary lymphoid structures inside the tumor microenvironment are believed to foster B‐cell‐dependent antitumor immunity, perhaps via the formation of ICs and cross‐priming of tumor‐specific CD8+ T cells.[46]
