摘要:
The present invention provides a regulatory T (Treg) cell expressing an antigen chimeric receptor (CAR) comprising a) at least one antigen binding domain, b) a transmembrane domain, and c) a cytoplasmic signaling domain comprising at least one primary cytoplasmic signaling domain and at least the co-stimulatory signaling domain of CD137, wherein said antigen binding domain specifically binds an antigen that is expressed on the surface of a target cell or a tag of a tagged polypeptide that binds to an antigen expressed on the surface of a target cell or a soluble antigen. Compositions comprising said Treg cells, and methods of enrichment and analysis of activated Tregs that express said CAR are also disclosed.
