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.
