WebThe reactivation of T cells after blocking PD-L1/PD-1 interactions requires T cell CD28 signaling (47, 48). Therefore, the lack of effect of 43H12 blockade of trans interactions between CD80 on T cells and PD-L1 on MC38 tumor cells that lack of CD80 could be explained by the absence of CD28 interaction with CD80 on tumor cells. WebApr 13, 2024 · Following introduction of a CAR structure, the PD-1 gene of CAR-T cells is knocked out using CRISPR/Cas9, so that the CAR-T cell does not express PD-1, resulting in improved tumor killing efficiency of AJMUC due to the release of inhibition in the signaling pathway PD-1/PD-L1 in the tumor microenvironment. sharon jeffrey
