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.

In this Q&A, Cell Press Community Review Scientific Editor Leia Judge talks to Dr. Clint Allen and Dr. Sandro Santagata about their new papers "Phenotypic plasticity and reduced tissue retention of exhausted tumor-infiltrating T cells following neoadjuvant immunotherapy in head and neck cancer" and "Lymphocyte networks are dynamic cellular communities in the immunoregulatory landscape of lung adenocarcinoma" and their experiences with publishing through Cell Press Community Review.

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.

Discrete tissue niches are emerging as essential prerequisites enabling cell communication and function in both homeostasis and disease. In a recent Cell paper, Di Pilato et al. identify a unique dendritic cell-cytotoxic T cell crosstalk within the perivascular space that facilitates T cell survival and proliferation and drives anti-tumor activity.

The mechanisms through which tumor antigen-specific T cells are elicited in natural or chemotherapy-induced immunosurveillance have been elusive. In this issue of Cancer Cell , two papers by Broz and colleagues and Ruffell and colleagues delineate an important role for a specific dendritic cell subset characterized by CD103 expression, dependence on transcription factors Batf3 and Irf8, and interleukin-12 production.

While the human NOTCH1 gene initially was cloned as part of a translocation breakpoint in T cell acute lymphoblastic leukemia (T-ALL) tumors, this translocation is present in only a small percentage of T-ALL patients. A recent paper by demonstrates that novel types of activating mutations in the NOTCH1 gene occur in more than half of all T-ALL cases, implicating NOTCH1 as a major player in the etiology of T-ALL.
