Abstract
Activation of bone morphogenetic protein (BMP) 4 signaling promotes the survival of retinal ganglion cell (RGC) after acute injury. In this study, we investigated the role of the BMP4 signaling pathway in regulating the degeneration of retinal ganglion cells (RGCs) in a mouse glaucoma model and its potential application in retinal stem cell. Our results demonstrate that BMP4-GPX4 not only reduces oxidative stress and iron accumulation but also promotes neuroprotective factors that support the survival of transplanted RSCs into the host retina. These findings suggest a novel therapeutic approach for glaucoma involving the modulation of the BMP4-GPX4 pathway to protect RGCs and improve visual function through enhanced RSC differentiation.
