Amgen study finds bone marrow immune cells can enter aging brain
AMGN•A study involving Amgen researchers found that bone marrow-derived immune cells can enter the aging brain and contribute to its resident immune cell population.
1. Study findings
Researchers traced bone marrow-derived immune cells entering the aging brain using mutations acquired during life. The findings challenge the view that the brain’s immune system is largely self-contained and may offer insights into disease beyond inherited genetics.
