Alzheimer’s disease is the most common cause of dementia. None of the available drugs can cure the disease. Chimeric Antigen Receptor (CAR) macrophages, because of their phagocytic activity, have potential as a cellular treatment for amyloid aggregation. In this study, we generated an anti-amyloid CAR hematopoietic progenitor cell line. By inducing the progenitor cell line to differentiate into macrophages, we show that the anti-amyloid CAR-Macrophage has enhanced specific phagocytic activity towards amyloid in in vitro experiments. In addition, in ex vivo experiments, anti-amyloid CAR significantly reduces the plaque load on brain slice from APP/PS1 mice when compared to a non-targeted CAR. We then transduce the progenitor cell line with GFP-luciferase and found that transduction of GFP-luciferase did not have a significant effect on the phagocytosis of amyloid. By tracking the luciferase activity in brain, we found that these CAR-macrophages can live for more than 10 days after intracranial injection.
