Dataset Summary

Title	TXNRD1 drives innate immune response in senescent cells and promotes age-associated inflammation
Description	Sterile inflammation, also known as inflammaging, is a hallmark of tissue ageing. Cellular senescence contributes to tissue aging in part through secretion of proinflammatory factors known as senescence-associated secretory phenotype (SASP). Thioredoxin reductase 1 (TXNRD1) genetic variability is associated with aging and age-associated phenotypes such as late-life survival, activity of daily living, and physical performance at old age. TXNRD1 role in regulating tissue ageing has been attributed to its enzymatic role in regulating cellular redox. Here we show that TXNRD1 drives SASP and inflammaging through the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) innate immune response pathway independently of its enzymatic activity. TXNRD1 localizes to cytoplasmic chromatin fragment and interacts with cGAS in a senescence status dependent manner. TXNRD1 enhances the enzymatic activity of cGAS. TXNRD1 and its interaction with cGAS is necessary for the SASP. TXNRD1 is required for both the tumor-promoting and immune-surveillance functions of senescent cells, which are mediated by SASP in vivo in mouse models. Treatment of aged mice with an TXNRD1 inhibitor that disrupts its interaction with cGAS, but not an inhibitor of its enzymatic activity, downregulated inflammaging in several tissues. In summary, our results report TXNRD1 promotes inflammaging via the innate immune response. They indicate that TXNRD1 and cGAS interaction is a relevant target for selectively suppressing inflammaging.
