The Γδ T-Cell Population Changes with Age
A recent mouse study shows that aging dramatically reshapes the peripheral γδ T‑cell compartment, expanding innate‑like subsets that produce higher levels of IL‑17. The age‑associated shift coincides with a marked loss of the transcription factor Foxo1 within these cells. Researchers identified type I interferons as an extrinsic signal that down‑regulates Foxo1, enhancing the rapid response capacity of IL‑17‑producing γδ T cells. These findings parallel similar Foxo1 dynamics observed in α/β T cells, suggesting a common regulatory pathway driving immunosenescence.
