Switching on the green light for chimeric antigen receptor T-cell therapy

Abstract

Adoptive cellular therapy involving genetic modification of T cells with chimeric antigen receptor (CAR) transgene offers a promising strategy to broaden the efficacy of this approach for the effective treatment of cancer. Although remarkable antitumor responses have been observed following CAR T-cell therapy in a subset of B-cell malignancies, this has yet to be extended in the context of solid cancers. A number of promising strategies involving reprogramming the tumor microenvironment, increasing the specificity and safety of gene-modified T cells and harnessing the endogenous immune response have been tested in preclinical models that may have a significant impact in patients with solid c..
