The CD58-CD2 axis regulates T cell-mediated cancer immunity, but little is known about the regulation of CD58. In two recent papers pubished in Cancer Cell , Miao et al. and Ho et al. define a mechanism of CD58 regulation by CMTM6 and show an unexpected yin-yang link between PD-L1 and CD58.

Cytotoxic T lymphocytes recognize and kill cancer cells when the latter present antigenic epitopes complexed with MHC class I molecules on their surface. In a recent Science paper, Mangalhara et al. show that alterations of the mitochondrial electron flow upregulate multiple factors involved in antigen presentation via a succinate-dependent epigenetic mechanism.

Two papers published in this edition of Cancer Cell (Zheng et al., 2022 and Veatch et al., 2022) provide an elegant illustration of how single-cell sequencing can be used to define a molecular phenotype which identifies tumor-specific T cells.
