flag A Johns Hopkins study finds BVRA protects brain cells by boosting antioxidant defenses independently of bilirubin, offering new hope for treating Alzheimer’s and Parkinson’s.

flag A Johns Hopkins study reveals that the enzyme BVRA protects brain cells from oxidative stress independently of its role in bilirubin production. flag It shields neurons by directly regulating NRF2, a key protein controlling antioxidant defenses, and maintaining mitochondrial health and immune function. flag In mice lacking BVRA, NRF2 failed to activate, weakening protection against damage linked to Alzheimer’s and Parkinson’s. flag Surprisingly, BVRA variants unable to produce bilirubin still offered protection, confirming a separate, crucial role. flag The findings, published in PNAS, suggest new therapeutic pathways for neurodegenerative diseases, though human applications remain years away.
