WebThe immune checkpoint receptor PD-1 and its ligand, PD-L1, have emerged as key regulators of anti-tumor immunity in humans. Recently, we reported an ultra-high-affinity PD-1 mutant, termed high-affinity consensus (HAC) PD-1, which shows superior therapeutic efficacy in mice compared with antibodies. Web25 de ago. de 2024 · On the other hand, genes with high EC 50 such as Ccl4 show a substantial sensitivity to PD-1 even in high-affinity T cells, and their PD-1 sensitivity is further increased in low-affinity T cells. ...
