WebNov 5, 2024 · CMG1A46 is a 151 KD IgG-like "1:(1+1)" tri-specific antibody constructed on Chimagen's TRIAD platform. It simultaneously targets CD3 on T cell and two different biomarkers - CD20 and CD19 (abundancy of which proven to be intact post CD20-targeted treatment) - on tumor cells, recruiting T cells to kill tumor cells expressing CD19 and/or … Web那么,pd-l1×cd3发挥作用的机制是怎样的呢? 研究人员发现pd-l1×cd3在rag1敲除的荷瘤小鼠(t、b细胞缺陷)中不起作用。此外,在用抗体清除免疫正常小鼠体内的cd8+ t细胞后,治疗作用也消失了,这说明pd-l1×cd3的治疗作用依赖于cd8+ t细胞介导的抗肿瘤免疫反应。
