Amgen Study Finds Bone Marrow Immune Cells Can Enter Aging Brain
- A study involving Amgen researchers, published in Nature, found bone marrow-derived immune cells can enter the aging brain.
- These cells contribute to the brain’s resident immune cell population, challenging the view that its immune system is largely self-contained.
- Researchers traced the cells using mutations acquired during life, highlighting potential insights into disease beyond inherited genetics.
