Research Article: Role of Circulating Exosomal miRNA- in Early Diabetic Retinopathy

Date Published: 2023-07-04

Abstract:
By , the global population with diabetes is estimated to reach million. With increasing number of adults with diabetes and longer life expectancies, the diabetic retinopathy (DR) population is rising worldwide. From to , the rate of global visual impairment and blindness due to diabetic retinopathy increased by % and %, respectively. Currently, DR is one of the leading causes of preventable blindness among adults. It is the fifth leading cause of moderate and severe vision impairment (MSVI) and blindness., The disease severity and economic burden make early diagnosis and intervention necessary. However, to date, no accurate biomarkers can predict DR occurrence, and the pathophysiology of DR is highly complex, with inflammation and oxidative stress playing significant roles. NF?B, a key transcription factor regulating many inflammatory genes, plays an important role in the progression of DR. The expression of NF?B is significantly upregulated in diabetes. Excessive NF?B activity disrupts the integrity of the inner blood-retinal barrier (iBRB) by reducing the expression of tight junction proteins. Moreover, it exacerbates various cellular inflammatory responses within the retina, leading to cellular dysfunction.,
