Uncovering how occludin protein maintains blood-brain and blood-retinal barriers
The blood-brain and blood-retinal barriers are protective systems that prevent harmful substances from entering the brain and eyes. These barriers are created by cells that are joined tightly together by proteins. Dysfunctional barriers can cause a range of diseases, including stroke, brain tumors and blinding eye diseases such as diabetic retinopathy.
