BioXcell热销产品--BE0273 InVivoMab anti-mouse PD-1 (CD279)
产品描述:
BioXcell InVivoMab anti-mouse PD-1 29F.1A12单克隆抗体与小鼠PD-1(也称为CD279)反应。PD-1是一种50-55kDa的细胞表面受体,由Pdcd1基因编码,属于Ig超家族的CD28家族。PD-1在CD4和CD8胸腺细胞以及活化的T和B淋巴细胞和髓细胞上瞬时表达,在成功消除抗原后PD-1的表达下降。此外,在B细胞前阶段,Pdcd1 mRNA在发育中的B淋巴细胞中表达。PD-1的结构包括ITIM(基于免疫受体酪氨酸的抑制基序),这表明PD-1负调控TCR信号。PD-1通过结合B7家族的成员PD-L1和PD-L2发出信号。在配体结合后,PD-1信号传导抑制T细胞活化,导致增殖减少,细胞因子产生和T细胞死亡。此外,PD-1敲除动物表现出扩张型心肌病、脾肿大和外周耐受丧失,在小鼠的外周耐受性和预防自身免疫性疾病中发挥关键作用。诱导的PD-L1表达常见于许多肿瘤,包括鳞状细胞癌、结肠癌和乳腺癌。PD-L1过度表达会导致肿瘤细胞对CD8T细胞介导的裂解的抗性增加。在黑素瘤的小鼠模型中,可以通过用阻断PD-L1与其受体PD-1之间相互作用的抗体治疗来暂时抑制肿瘤生长。由于这些原因,目前正在探索抗PD-1介导的免疫疗法作为癌症治疗。与RMP1-14和J43抗体一样,29F.1A12抗体在体内阻断PD-1与其配体的结合。
