Researchers here report on a way to reverse some of the age-related dysfunction observed in the hematopoietic stem cell population resident in bone marrow. These cells are responsible for generating red blood cells and immune cells. Some fraction of the age-related decline in immune function derives from issues in the hematopoietic cell populations originating with hematopoietic stem cells. It seems that hematopoietic stem cells have a distinct iron metabolism, and iron accumulation produces dysregulation in these cells. Reducing the presence of iron in hematopoietic stem cells reverses some of these changes. In the bigger picture, iron is connected to aging, and global reductions…
