针对人整联蛋白α6β4亚基的第二代单克隆抗体已经制备。MAb 450-9D、10 D和11 A1在β4分子上的不同位点反应,MAb 450- 30 A1和33 D在α6亚基上的相同位点反应。已经开发了使用这些单克隆抗体组合的双决定簇(双位点)放射免疫测定。β4的两种测定法可区分完整β4分子和从C末端截短的β4分子(c型),而另一种测定法可测量α6亚基的存在。来自双位点测定的数据支持以下结论:(1)结肠肿瘤和正常结肠粘膜表达大量α6β4,尽管仅检测到β4的c型;(2)没有证据表明α6β4在结肠中表达;然而,某些肺肿瘤中可能存在这种复合物。即使β4亚基的胞质结构域不存在,α6和β4的胞外结构域也可以彼此缔合。针对β4分子特异性结构域的单克隆抗体可能在抗肿瘤治疗中有一定的应用价值。
Second generation monoclonal antibodies to the α6β4 subunits of human integrins have been prepared. MAbs 450-9D, 10D, and 11A1 react at different sites on the β4 molecule and MAbs 450-30A1 and 33D react at the same site on the α6 subunit. Double determinant (two-site) radioimmunoassays using combinations of these MAbs have been developed. Two assays for β4 distinguish between the whole β4 molecule and the β4 molecule truncated from the C-terminus (form c) while another assay measures the presence of α6 subunits. Data from the two-site assays support the following conclusions: (1) Colon tumors and normal colon mucosa express large amounts of α6β4 although only form c of the β4 was detected; (2) There is no evidence for α6β4 expression in colon; however, some of this complex may be present in certain lung tumors. The extracellular domains of α6 and β4 can associate with each other even if the cytoplasmic domain of the β4 subunit is not present. MAbs to specific domains of the β4 molecule may be useful in an...
