The blood–retina barrier in health and disease

open access: yesThe FEBS Journal, 2021
The blood–retina barrier (BRB) is the term used to define the properties of the retinal capillaries and the retinal pigment epithelium (RPE), which separate the systemic circulation from the retina. More specifically, the inner blood–retina barrier (iBRB)

Retina Metabolism and Metabolism in the Pigmented Epithelium: A Busy Intersection.

open access: yesAnnual Review of Vision Science, 2021
The outer retina is nourished from the choroid, a capillary bed just inside the sclera. O2, glucose, and other nutrients diffuse out of the choroid and then filter through a monolayer of retinal pigment epithelium (RPE) cells to fuel the retina.

Identification of early pericyte loss and vascular amyloidosis in Alzheimer’s disease retina

open access: yesActa Neuropathologica, 2020
Pericyte loss and deficient vascular platelet-derived growth factor receptor-β (PDGFRβ) signaling are prominent features of the blood–brain barrier breakdown described in Alzheimer’s disease (AD) that can predict cognitive decline yet have never been ...
