Generation of hypoxia-sensing chimeric antigen receptor T cells

STAR Protoc. 2021 Aug 6;2(3):100723. doi: 10.1016/j.xpro.2021.100723. eCollection 2021 Sep 17.

Abstract

Exploiting hypoxia in solid malignancies to restrict expression of chimeric antigen receptors (CARs) on engineered T cells to the tumor microenvironment overcomes the risk of on-target off-tumor toxicity and minimizes tonic signaling, which promotes CAR T cell exhaustion. This protocol summarizes the synthetic biology underlying the development of a stringent oxygen-sensitive CAR for in vitro and in vivo preclinical characterization. For complete details on the use and execution of this protocol, please refer to Kosti et al. (2021).
