Abstract
The disclosure relates generally to ligand-based chimeric antigen receptor (CAR) cells. More specifically, the CAR cells express B-cell activating factor (BAFF) protein for recognition by a receptor of BAFF on the surface of a cell. CAR cells can include cytotoxic T lymphocytes, natural killer (NK) cells or natural killer T (NKT) cells that express a chimeric receptor that recognizes a receptor of BAFF. The disclosure further relates to methods of treating a variety of conditions, such as cancers and autoimmune diseases, using the disclosed CAR cells.
