Targeting solid tumours by chimeric antigen receptor (CAR) T cells require strategies that improve trafficking and effector function of these cells in the immunologically hostile cancer microenvironment. Here, authors show that CAR T cells engineered with incorporation of the CD28 transmembrane domain to the 4-1BB costimulatory domain and a membrane-bound form of IL-12 can achieve efficient anti-tumour activity and promote systemic disease targeting via regional T cell delivery in multi-metastatic disease models.
