Fas是一种细胞表面分子 [1 ] ,可与其特异性配体 Fas-L igand(Fas L )结合 ,诱导细胞凋亡的发生。许多肿瘤细胞可表达 Fas L ,明显减弱 Fas阳性细胞毒性淋巴细胞的攻击能力 ,是肿瘤细胞逃避机体免疫攻击的新机制 ,在肿瘤的发生和发展中起重要作用。本文拟研究 Fas、Fas L 在视?
Fas is a cell surface molecule [1] that binds to its specific ligand Fas-Ligand (Fas L) and induces apoptosis. Many tumor cells can express Fas L and significantly weaken the attack ability of Fas-positive cytotoxic lymphocytes. It is a new mechanism of tumor cells escaping immune attack and plays an important role in tumorigenesis and development. This article is to study Fas, Fas L in the visual?
