Cancer Pathway Found to Weaken Brain and Eye Barriers

Researchers have uncovered a surprising connection between a cancer-related signaling pathway and the blood-brain and blood-retina barriers. The study shows that the tumor-suppressing protein p53 weakens the Norrin/Frizzled4 pathway, which is crucial for maintaining these protective barriers.

Eye Clues to Schizophrenia Risk Found in Retinal Thickness

The retina, as part of the central nervous system, may reflect early signs of brain disorders like schizophrenia. A large-scale genetic study found that people with higher genetic risk for schizophrenia tend to have thinner retinas, even in the absence of symptoms.

Changes in the Retina Can Be Linked to Parts of the Brain of Healthy Subjects at Risk of Alzheimer’s

In cognitively healthy people with a genetic risk for Alzheimer's, retinal changes have been associated with alterations in the entorhinal cortex, hippocampus, and lingual gyrus. Researchers say retinal changes can be used to track changes in brain structures associated with Alzheimer's in those with genetic risk factors.
