RecombiMAb anti-mouse PD-1 (CD279)(29F.1A12™-CP004單克隆抗體)介紹

29F.1A12™-CP004單克隆抗體是原始29F.1A12™克隆號的重組嵌合型抗體。可變結構域序列與原始29F.1A12™克隆號相同,但是恒定區(qū)序列已經(jīng)從大鼠IgG2a變?yōu)樾∈驣gG1。29F.1A12™-CP004抗體像原始大鼠IgG2a抗體一樣無Fc突變。

29F.1A12™-CP004單克隆抗體與小鼠PD-1(程序性死亡-1蛋白,也稱為CD279)反應。PD-1是一種50-55 kDa的細胞表面受體,由Pdcd1基因編碼,屬于免疫球蛋白超家族的CD28家族。PD-1在CD4和CD8胸腺細胞以及活化的T和B淋巴細胞和骨髓細胞上瞬時表達。成功清除抗原后,PD-1表達下降。此外,Pdcd1 mRNA在前B細胞階段發(fā)育中的B淋巴細胞中表達。PD-1的結構包括一個ITIM(免疫受體酪氨酸抑制基序),表明PD-1負調(diào)節(jié)TCR信號。PD-1通過結合它的兩個配體PD-L1和PD-L2發(fā)出信號,這兩個配體都是B7家族的成員。配體結合后,PD-1信號抑制T細胞活化,導致增殖、細胞因子產(chǎn)生和T細胞死亡減少。此外,已知PD-1在小鼠的外周耐受性和預防自身免疫性疾病中起關鍵作用,因為PD-1敲除動物表現(xiàn)出擴張性心肌病、脾腫大和外周耐受性喪失。誘導的PD-L1表達常見于許多腫瘤,包括鱗狀細胞癌、結腸腺癌和乳腺腺癌。PD-L1過度表達導致腫瘤細胞對CD8 T細胞介導的裂解的抗性增加。在黑色素瘤的小鼠模型中,通過用阻斷PD-L1和它的受體PD-1之間的相互作用,腫瘤生長可以暫時被抑制。目前PD-1是癌癥免疫療法的熱門靶點之一。
