Editor's Summary

Dying Cells Protect the Neighborhood
In addition to releasing a number of factors that induce the production of proinflammatory cytokines, dying cells can promote wound healing and tissue homeostasis by inducing the proliferation of surrounding cells in a process known as compensatory proliferation. Nishina et al. found that in dying hepatocytes reactive oxygen species triggered the production of the cytokine interleukin-11 (IL-11), which induced the proliferation of surrounding cells by activating the transcription factor STAT3. Consistent with these in vitro findings, IL-11 signaling protected hepatocytes in a mouse model of acetaminophen-induced liver injury, and mice deficient in a component of the IL-11 receptor had exacerbated disease. Together, these findings suggest that IL-11 stimulates compensatory proliferation in response to oxidative stress.
