  • Publication number: 20200283727
    Abstract: Provided herein are methods of expanding B cells, and in particularly B10 cells capable of producing IL-10, ex vivo. The methods include incubation of harvested B cells in the presence of IL-21. Compositions comprising the ex vivo expanded B cells and methods of using the expanded B cell-containing compositions to treat diseases or conditions are also provided. Methods of assessing B10 cell function in a subject are also provided.
    Type: Application
