Rothlin 和 Ghosh 预览了 Murray 和 El Kasmi 实验室的工作,该工作确定了一种新机制,通过该机制,衰老细胞可以逃避巨噬细胞的清除,并阻止巨噬细胞清除凋亡尸体。慢性衰老可引发病理性炎症。在本期中,Schloesser 等人。 (2022. J. Cell Biol. https://doi.org/10.1083/jcb.202207097) 证明衰老细胞利用“别吃我”信号来抑制巨噬细胞吞噬它们的能力,并另外阻止巨噬细胞清除邻近的尸体,揭示了衰老可能引发炎症的新机制。
Rothlin and Ghosh preview work from the Murray and El Kasmi labs that identifies a new mechanism by which senescent cells evade their removal by macrophages and block macrophages from eliminating apoptotic corpses. Chronic senescence can trigger pathological inflammation. In this issue, Schloesser et al. (2022. J. Cell Biol. https://doi.org/10.1083/jcb.202207097) demonstrate that senescent cells employ “don’t eat me” signals that inhibit the ability of macrophages to engulf them and additionally prevent macrophages from removing neighboring corpses, revealing a new mechanism by which senescence may contribute to triggering inflammation.
