Study Reveals Novel Brain Recovery Mechanism After Traumatic Brain Injury
Washington, 13 Mar (ONA) --- A team of researchers from the Medical University of South Carolina, led by Dr. Onder Albayram, has uncovered a groundbreaking protective response in the brain following traumatic brain injury (TBI).
Published in PNAS Nexus, their findings suggest a natural brain repair mechanism that could pave the way for drug treatments to enhance brain recovery post-concussion and prevent long-term brain diseases.
Dr. Albayram emphasized the potency of the brain's inherent recovery mechanisms and the potential for treatments that facilitate self-healing processes.
Repetitive mild TBIs, prevalent among athletes and military personnel, can lead to severe long-term consequences, including chronic traumatic encephalopathy and neurodegenerative diseases like Alzheimer's.
The study reveals a crucial role played by the protein p17 in initiating the brain's healing process, known as mitophagy, after repeated concussions.
Removing p17 in mouse brain cells led to the development of secondary diseases post-injury, underscoring its protective function. Moreover, administering an analog drug to trigger mitophagy significantly improved brain disease in mice.
Observations in postmortem human brains further supported the significance of p17, suggesting its potential as a target for future treatments.
Dr. Albayram envisions harnessing the brain's natural recovery abilities akin to how vaccines boost the body's immune response, offering hope for improved treatments not only for TBIs but also for broader brain diseases.
