Advanced Science, EarlyView.The αvβ3‐mediated SPRC@MPDA‐RGD targets broken endothelial cells and controllably releases SPRC. CSE is then activated to produce endogenous H2S, which inhibits ferritinophagy. In brief, H2S inhibits autophagy by activating the PI3K/Akt/mTOR pathway, thereby suppressing the ferroptosis process mediated by NCOA4, and ultimately promoting the ...
