IMMUNOLOGY:
T Before NK

H. Robson MacDonald

Natural killer T (NKT) cells are a small subset of T lymphocytes that express both activating T cell receptors and inhibitory NK cell receptors. In a Perspective, MacDonald discusses intriguing new findings published here (Benlagha et al.) and elsewhere, that identify an early NKT cell precursor in the thymus that expresses the T cell receptor but not NK cell receptors, yet can give rise to NKT cells that express both.
