The transient expression of CD61 and its unconventional pairing with CD103 at the immune synapse enhances T cell receptor signaling, improves anti-tumor cytotoxicity and mitigates tumor growth. Clinically, CD61+ tumor infiltrating lymphocytes (TILs) exhibit enhanced effector functions and show limited cellular exhaustion.

Ganesan, A. P. et al. Tissue-resident memory features are linked to the magnitude of cytotoxic T cell responses in human lung cancer. Nat. Immunol. 18, 940–950 (2017). This paper reports lung tumors with enriched tissue-resident memory T cell transcriptomes, including those that express CD103, which are predictive of better survival outcome.
Malik, B. T. et al. Resident memory T cells in the skin mediate durable immunity to melanoma. Sci. Immunol. 2, eaam6346 (2017). This paper shows that melanoma antigen-specific tissue resident memory T cells require CD103 expression to establish tissue-residency in skin, and for protection against melanoma rechallenge.
