Senescent endothelial cells: a potential target for diabetic retinopathy

Area of Science:

• Ophthalmology
• Endocrinology
• Cell Biology

Background:

• Diabetic retinopathy (DR) is a significant complication of diabetes, leading to vision loss.
• Current treatments for DR, mainly antiangiogenic therapies targeting vascular endothelial growth factor, have limitations due to DR's complex pathogenesis.
• Emerging evidence implicates premature endothelial cell (EC) senescence in hyperglycemia as a key factor in DR development.

Purpose of the Study:

• To review the inducers and mechanisms of EC senescence in diabetic retinopathy pathogenesis.
• To summarize current research on senotherapeutics and strategies targeting senescent ECs (SECs) for DR treatment.
• To highlight key factors in EC senescence stages for developing innovative DR treatments.

Main Methods:

• Literature review focusing on endothelial cell senescence in diabetic retinopathy.
• Analysis of emerging studies on senotherapeutics and targeting senescent endothelial cells.
• Identification of key factors involved in different stages of endothelial cell senescence.

Main Results:

• Premature EC senescence in hyperglycemia plays multifaceted roles in DR pathogenesis.
• Targeting SECs presents a promising therapeutic avenue for DR, complementing existing strategies.
• Understanding EC senescence mechanisms is crucial for advancing DR treatment.

Conclusions:

• Senotherapeutics targeting SECs represent a novel and promising approach for diabetic retinopathy.
• Further research into the specific roles of EC senescence at different disease stages is critical.
• Innovative strategies targeting EC senescence could overcome limitations of current antiangiogenic therapies for DR.
