🚨How do mitochondria sense and respond to metabolic stress from the environment in diabetes? 🤔

In new work out in #ScienceAdvances, we show that innate immune signaling promotes β cell compensation for metabolic stress by engaging mitophagy. 🚨1/n

TRAF6 integrates innate immune signals to regulate glucose homeostasis via Parkin-dependent and Parkin-independent mitophagy

TRAF6 bridges innate immune signaling to mitophagy to promote glucose control during metabolic stress.

-Mitochondrial ROS triggers mitophagy through activating the DNA damage response signaling pathway

Thanks to @biomednews.bsky.social

PP2A-B55α activates TFEB upon mitochondrial damage to support Parkin-dependent mitophagy.
