Weakening Immune System? Key Protein May Be the Reason
Research indicates that a decline in the protein platelet factor 4 contributes to immune system aging by causing blood stem cells to multiply excessively and become prone to mutations linked to age-related diseases. Restoring this protein in studies involving older mice and human stem cells rejuvenated aging blood and immune cells, suggesting a potential therapeutic target for age-related immune decline. These findings, published in *Blood*, offer a promising avenue for interventions aimed at maintaining a healthy immune system in older adults.
