The present invention relates to the adoptive therapy using notably CAR-T cells. Here
the inventors used a lentiviral vector approach to silence RINF expression in a shRNA dependent manner and evaluate the consequences of RINF silencing on human CAR-T cells proliferation ex vivo and their functionality and capacity to eradicate tumor cells in vivo. More, the proposed methodology to improve CAR-T cells persistence and efficacy by disrupting RINF/CXXC5 is not restricted to patients suffering from hematological or solid cancers (anti-CD19, anti-EGFR, anti-BCMA…) but could be also used to improve the efficacy of ACT in non-cancer diseases by such as lupus (1), cardiac fibrosis (2) or aging related-disorders (3).
Thus, the present invention relates to an immune cell characterized in that it is defective for RINF.
