Reversing Aging: Exercise Rejuvenates Brain Cells

Exercise can rejuvenate brain immune cells and reduce aging effects, highlighting the need for tailored exercise programs to support cognitive health.

New research published today (May 15) in the scientific journal Aging Cell provides insights into how exercise may help to prevent or slow cognitive decline during aging.

For the study, investigators assessed the expression of genes in individual cells in the brains of mice. The team found that exercise has a significant impact on gene expression in microglia, the immune cells of the central nervous system that support brain function. Specifically, the group found that exercise reverts the gene expression patterns of aged microglia to patterns seen in young microglia.
