T cells recognize small fragments of microorganisms (antigens) on the surface of other cells using T cell antigen receptors. The mechanism by which these receptors signal into T cells is controversial, but two recent studies provide important new clues.
T细胞利用T细胞抗原受体识别其他细胞表面微生物的小片段（抗原）。这些受体向T细胞发出信号的机制存在争议，但最近的两项研究提供了重要的新线索。
