Scientists traced the stress alarm that triggers kidney cell explosion

PubMed · 2026-01-20

Researchers found that a stress-signaling protein called ATF4 drives kidney cell death and inflammation after drug exposure, and that blocking it with a new compound or gene-silencing nanoparticles significantly protected kidney function in mice.

1

ATF4 was markedly upregulated in damaged kidney tubule cells in both human and mouse AKI models, and its deletion significantly reduced kidney dysfunction and inflammation.

2

ATF4 drives pyroptosis (inflammatory cell death) by activating the STAT1-GBP2 signaling axis, which then triggers NLRP3 inflammasome assembly.

3

Two therapeutic strategies, the ISR antagonist ERMT1 and engineered nanobiologics silencing ATF4 in tubule cells, both significantly reduced renal injury in preclinical models.
