Weak Immune System? Declining Protein May Be to Blame
Research indicates that a decline in platelet factor 4, a naturally occurring protein, contributes to immune system aging by causing blood stem cells to multiply excessively and become prone to mutations linked to age-related diseases. Studies in mice and human stem cells suggest that restoring platelet factor 4 could rejuvenate aging blood and immune cells, offering potential therapeutic avenues for age-related immune decline.
