When Macrophages Disappear, Skin Blood Vessels Age! Check out our new study @nature.com that uncovers how the loss of capillary-associated macrophages with age blocks vessel repair and blood flow, revealing a new cellular trigger of tissue aging. #Aging #Immunology 👇👇 www.nature.com/articles/s41...
