Fibroblast-derived neuropilin 1 alleviates renal fibrosis progression.

ABSTRACT: Chronic kidney disease (CKD) is a major global health challenge affecting over 10% of the adult population. A hallmark of CKD progression is the transdifferentiation of kidney fibroblasts into extracellular matrix-producing myofibroblasts, a key mechanism involved in the decline of kidney function and the development of kidney failure. Fibroblasts maintain the structural integrity of the kidney and support epithelial survival, repair, and regeneration after acute kidney injury. Maladaptive repair is a failure to resolve fibroblast activation, which ultimately progresses to chronic injury and CKD. In this study, we showed that the membrane-bound coreceptor neuropilin 1 (NRP1) was essential to maintain fibroblast function and prevent their transdifferentiation into myofibroblasts. We used th
