FoxO1 regulates the transcription of genes involved in diabetes, cancer and ageing. In this issue of , Olefsky and colleagues report that FoxO1 also causes inflammation by regulating the pro-inflammatory Tlr4 signalling pathway in macrophages. Insulin-mediated activation of Akt inactivates FoxO1 and thereby limits the inflammatory response.
FoxO1 调节与糖尿病、癌症和衰老相关基因的转录。在本期的 中，Olefsky 及其同事报道 FoxO1 还通过调节巨噬细胞中的促炎 Tlr4 信号通路引起炎症。胰岛素介导的 Akt 激活使 FoxO1 失活，从而限制了炎症反应。
