Cancer T Cells Get Under the Skin
T cells bearing the T cell receptor reside in large numbers within the epidermis of the skin. The growing evidence that T cells contribute to dermal integrity is supported by the study by Girardi et al., who show these lymphocytes can protect against cutaneous malignancy. Thus, in the absence of T cells, mice coped poorly with experimentally induced forms of skin carcinoma. Induction of malignancy correlated with the increased amounts of the protein Rae-1, which contributed to the killing of carcinoma cells by a T cell line in vitro. Binding studies revealed that Rae-1 interacts with the NKG2d receptor on T cells, which suggests that this ligand may be a functional homolog of tumor-related MICA/B proteins in humans. Pardoll provides a Perspective on the article.
