  • Publication number: 20220411751
    Abstract: Provided herein are methods for obtaining populations of reprogrammed MO-homeostatic tolerogenic microglial cells. The methods include providing an initial population of monocytes, e.g., peripheral blood monocytes (PBMC), from a subject, and reprogramming the cells by maintaining the PBMC in culture ex vivo in the presence of a sufficient amount of transforming growth factor-beta (TGF?) and interferon-gamma (IFN?) for a time and under conditions sufficient for the cells to become M0-homeostatic tolerogenic microglia. Also provided are methods of use of these cells, e.g., for the treatment of neurodegenerative diseases associated with inflammation, e.g., Alzheimer's Disease (AD); Multiple Sclerosis (MS), e.g.
