Synthetic promoters to induce immune-effectors into the tumor microenvironment

Abstract

Greenshpan et al. explore the use of synthetic promoters based on IFNgamma, TNF alpha and hypoxia responsive elements to control gene expression. The authors describe this technology in the context of chimeric antigen expression (CAR) and propose that this method can circumvent off-target toxic effects via specific expression of the CAR in the tumor microenvironment.
