PTEN checkMAITs type-17 innate-like T cells

PTEN, a tumour suppressor, also regulates T cell activation. A new study reports that PTEN acts as a cell-intrinsic rheostat linking TCR- and IL-23-mediated signalling to regulate development of type-17 innate-like T cells in the thymus. This work may have important implications for treating autoimmune and inflammatory diseases.
