}PURPOSE
Diabetic retinopathy (DR) is a major cause of blindness globally. Investigating the underlying mechanisms of DR would be aided by a suitable mouse model that developed key features seen in the human disease, and did so without carrying genetic modifications. This study was undertaken to produce such a model.
METHODS
Our panel of Collaborative Cross strains was screened for DR-like features after induction of diabetes by intravenous injection with alloxan or streptozotocin. Both flat…

In the setting of hyperglycemia, AION led to greater acute, postischemic microglial activation and elevation of VEGF levels, which likely contributed to greater retinal swelling acutely and worse retinal thinning and loss of retinal ganglion cells chronically.
Basigin can be a therapeutic target to restore the retinal vascular barrier function in the mouse model of diabetic retinopathy

It is demonstrated that basigin, a transmembrane molecule expressed in neural barrier-forming endothelial cells, is the molecule essential for vascular barrier impairment which is shared by various triggers including VEGF, TNFα and IL-1β.

Mouse models of diabetic Atherosclerosis show characteristic pathologies of DR that correlate with atherosclerosis, and the increased magnitude of these changes and responses to 4PBA in the peripheral retina suggest that future studies should be aimed at assessing regional differences in mechanisms of ER stress-related pathways in these mouse models.

Analysis of diabetic retinopathy-like changes revealed that these parameters were tightly correlated with the initial degree of vascular leakage; low levels reflected slow and limited retinal microvascular changes in mild cases and high levels reflected more rapid and extensive changes in moderate cases.

Findings indicate that diabetes and galactosemia lead to accelerated death in situ of both retinal pericytes and endothelial cells; the event is specific for vascular cells; it precedes histological evidence of retinopathy; and it can be induced by isolated hyperhexosemia.
