iRGD synergizes with PD-1 knockout immunotherapy by enhancing lymphocyte infiltration in gastric cancer

Abstract

The therapeutic efficacy of adoptive T cell transfer is limited by their ability to infiltrate solid tumours. Here, the authors show that loading the tumor penetrating cyclic peptide iRGD on the cell surface of T cells enhances their ability to penetrate the tumour, resulting in enhanced efficacy in a mouse model of gastric cancer.
