Researchers found that youthful proteins can make old brains act young again
Scientists have identified a specific blood protein called PF4 that can reverse age-related cognitive decline by rejuvenating the immune system and enhancing neural connections in the brain.
Platelet factor 4 is a protein found in young blood that effectively restores cognitive function in aging mice. Recent studies published in 2023 demonstrate that boosting this protein levels the playing field between young and old brains by reducing inflammation and improving synaptic plasticity.
