Necroptosis–senescence crosstalk in tubulointerstitial fibrosis: the mtDNA–cGAS–STING–PFKFB3 axis as a metabolic bridge
Background Chronic kidney disease progresses irreversibly toward tubulointerstitial fibrosis. Although renin-angiotensin system inhibitors and sodium-glucose cotransporter 2 inhibitors slow progression, they cannot block or reverse fibrosis. Recent work shows that necroptosis and cellular senescence in tubular epithelial cells are not independent events; they form a dynamically evolving continuum through the mitochondrial DNA-cyclic GMP-AMP synthase-stimulator of interferon genes-interferon regulatory factor 3-6-ph …
