Scientists discover a protein that protects the brain from Alzheimer’s damage
Researchers at Sanford Burnham Prebys have identified a protein called SORLA that may help protect the brain from Alzheimer's-related tau tangles. This discovery suggests a potential new therapeutic pathway to prevent the cognitive decline associated with neurodegenerative diseases.
Why it matters
Alzheimer's remains a leading cause of dementia, and identifying new protective proteins could lead to breakthrough treatments for millions of patients.
Alzheimer's disease and several other neurodegenerative disorders are linked to a damaging change in tau, a protein that normally helps support the internal structure of nerve cells. Under healthy conditions, tau stabilizes microtubules, the filament-like structures that help maintain neuronal shape and function. In disease, however, tau can twist into toxic tangles that interfere with the brain circuits it would normally help preserve.
Researchers at Sanford Burnham Prebys reported on July 17, 2026, in Science Advances that another protein may help protect the brain from this damage. Their findings raise the possibility that future therapies could strengthen this natural defense and reduce the harmful effects of tau-related disease.
Tau is normally found throughout the brain and nervous system, where it helps maintain the structure of neurons and the networks they form.
