W3/25单克隆抗体与大鼠CD4发生反应。CD4是免疫球蛋白超家族的55 kDa I型膜糖蛋白,作为细胞表面受体蛋白,它充当抗原呈递细胞(APC)显示的II类MHC分子的共受体(与TCR)。CD4由大多数胸腺细胞、辅助T细胞、NK-T细胞亚群表达,由树突状细胞和巨噬细胞弱表达。CD4在T细胞的发育中起着重要作用,是成熟T细胞最佳功能所必需的。克隆W3/25被用作“辅助性T细胞标记物”。克隆W3/25是一种不完全的单克隆抗体,但已被证明在体外中和CD4。几项体外研究还表明,W3/25单克隆抗体通过下调淋巴细胞表面的CD4分子来抑制CD4+T细胞活化。W3/25单抗还在MLR实验中抑制抗原诱导的T细胞增殖和IL2的产生。在预防性和实验性治疗性体内研究中,该抗体已被广泛用于调节实验性变态反应性脑脊髓炎(EAE)、佐剂性关节炎等疾病相关和机制参数。
