CD47 expression is critical for CAR T-cell survival in vivo

Abstract excerpt

BACKGROUND: CD47 is an attractive immunotherapeutic target because it is highly expressed on multiple solid tumors. However, CD47 is also expressed on T cells. Limited studies have evaluated CD47-chimeric antigen receptor (CAR) T cells, and the role of CD47 in CAR T-cell function remains largely unknown. METHODS: Here, we describe the development of CD47-CAR T cells derived from a high affinity signal regulatory...
