Autocrine PD-1-blocking nanobodies enhance the antitumor efficacy of TCR-like CAR-T cells by attenuating t cell exhaustion
In the SKOV3-A2 solid tumor xenograft model, WT1-CAR-Nb T cells mediated superior tumor growth control and significantly prolonged overall survival, which was closely correlated with enhanced intratumoral T cell infiltration and persistent in vivo expansion of engineered T cells.
