This task is made more difficult when the blood cells are misshapen, as they are in patients with sickle cell disease, which...
by University of California, Irvine Credit: CC0 Public Domain Combating Alzheimer’s and other neurodegenerative diseases by inserting healthy new immune cells into the brain has taken a leap toward reality. Neuroscientists at the University of California, Irvine and the University of Pennsylvania have found a way to safely thwart the brain’s resistance to them, vaulting...
