Endothelial cell senescence contributes to pathological retinal angiogenesis

Abstract

Background

Pathological retinal neovascularization is marked by microvascular lesions manifested initially as endothelial cell dysfunction and metabolic disturbances. However, the regulatory mechanism guiding retinal vascular endothelial cell function remian controversial.

Main body

Previous studies have demonstarted that high glucose or oxidative stress can induce premature senescence in endothelial cells, triggering inflammatory responses within the vascular system and promoting the secretion of pro-inflammatory factors, ultimately leading to pathological angiogenesis. Endothelial cell senescence has thus become a key target for anti-angiogenic therapies.

Conclusion

This review delves into current research on the mechanisms driving senescence-induced retinal angiogenesis and highlights potential target protein pathways, aiming to provide insights for future investigations.
