SAN FRANCISCO: In a new study entitled “Human umbilical cord blood-derived monocytes improve cognitive deficits and reduce ß-amyloid pathology in PSAPP mice” an international team of scientists showed that infusion of human umbilical cord blood cells (HUCBCs) into a mice model of Alzheimer’s disease improves animals’ cognitive performance by clearing amyloid-beta (Aβ) plaques. They discovered that immune cells called monocytes, which are present in HUCBCs infusion are the key players responsible for this improved phenotype. The study will be published…
