The cytotoxic T-lymphocyte antigen (CTLA) 4 was also required for the injection of anti-CTLA-4 antibodies into tumor-bearing mice leading to blockade of tumor growth [ 35 – 37 ]. WebbIt's principal ligand is MHC class II, to which it binds with higher affinity than CD4. LAG3 was cloned over 20 years ago as a CD4 homologue, but its function in the immune checkpoint was only defined in 2005 when it turned out to have a role in enhancing the function of Treg cells (regulatory cells). The molecular pathways that mediate LAG-3 ...

WebbTreg ablation in Foxp3iDTR mice, or by antibody-mediated Treg-selective blockade of IL-2 signaling, strongly reduces the lymphoma burden. We identify lymphoma B-cells as a major source of IL-2, and show that the effects of Treg depletion are reversed by the simultaneous depletion of Foxp3-negative CD4+ T-cells, but not CD8+ T-cells or natural … Webb24 sep. 2024 · 最近，MHCII反式激活因子（CIITA）被确定为LAG-3配体的关键调节因子。 CIITA不仅诱导MHCII表达，还诱导MHCII辅助分子表达，包括CD74和H2-DM。 MHCII的辅助分子有助于肽MHCII复合物（pMHCII）的形成和细胞表面分类，在传统的抗原呈递途径中表现出稳定的结构构象。 LAG-3区分pMHCII的构象并选择性地与稳定的pMHCII结合。 …
