| I. Background | |
|
淋巴細(xì)胞活化基因 3 (LAG-3)，又名 CD223，是一種 I 型跨膜蛋白，屬于免疫球蛋白超家族 (IgSF)。LAG-3 蛋白與 CD4 有同源結(jié)構(gòu)，兩者的胞外區(qū)均具有四個(gè) Ig 樣結(jié)構(gòu)域，但 LAG-3 在膜遠(yuǎn)端 Ig 樣結(jié)構(gòu)域內(nèi)還含有一種額外的環(huán)狀結(jié)構(gòu)，使其與MHC II的親和力較CD4高100倍。LAG-3 在活化的 T 細(xì)胞、B 細(xì)胞、漿細(xì)胞樣樹突狀細(xì)胞 (DC) 和 NK 細(xì)胞上表達(dá)。LAG3 可結(jié)合 MHC II類 (MHC II)分子外，也可結(jié)合纖維蛋白原樣蛋白 1（FGL-1）、α-突觸核蛋白原纖維 (α-syn) 和凝集素半乳糖凝集素-3 (Gal-3) 以及淋巴結(jié)竇內(nèi)皮細(xì)胞 C 型凝集素 (LSECtin) 。 |
