Protein discovered that may be linked to brain aging and memory

Scientists may have identified a key element in the brain aging process, a complex phenomenon that affects memory and cognitive functions as we age.

According to a study published in the journal "Nature Aging", the FTL1 protein may play an important role in this process.

The study analyzed changes in the brains of mice during aging, focusing on the mechanisms that influence the slowing of mental activity and memory impairment.

The researchers found that increased levels of the FTL1 protein were associated with poorer memory performance and reduced neural connections in the hippocampus, the part of the brain responsible for learning and memory.

Experiments showed that increasing this protein in young mice brought signs similar to brain aging, while its decrease in older mice was associated with improved cognitive functions and a more "younger" state of the brain.

The study's lead author, Dr. Saul Villeda from the University of California, San Francisco, said the results open up new possibilities for understanding and perhaps alleviating the effects of aging.

"We are seeing more opportunities to alleviate the most severe consequences of aging. It is a hopeful time to be working in the biology of aging," he said.
