用一组小鼠抗H-1、H-2、Le a、Le b、X、Y和前体血型决定簇的单抗对33名正常人唾液糖蛋白进行了分析。19 33人共表达Le b和Y决定簇(分泌物),6 33人共表达Le a和X决定簇(非分泌物)。红细胞类型分别为Le(a−b+)和Le(a+b−)。在其他七种唾液中,只有一种特异性表达,即Le a、Le b、X或Y,并且在一个样本中没有检测到这些决定因素。只有一份唾液样本表达了H-1特异性,没有一份样本表达了H-2或1型前体决定簇。分泌物中H-1和H-2结构的缺失以及由此导致的双岩藻糖基化的Le b和Y结构的表达可能是唾液腺分泌物的组织特异性特征。Le b与Y和Le a与X-的严格共表达支持了唾液腺中只有一种2-O-岩藻糖基半乳糖转移酶存在的结论,该酶既能使1型岩藻糖基化,又能使2型岩藻糖化。考虑到以前的工作表明参与形成这种结构的3-O-岩藻糖基N-乙酰氨基葡萄糖转移酶是一种普遍存在的酶,许多个体既不表达X-也不表达Y-特异性,这一发现是出乎意料的。在研究恶性肿瘤和其他疾病的血型表达变化时,应考虑组织中血型表型的个体化表达。
Salivary glycoproteins from 33 normal individuals were analyzed with a panel of mouse monoclonal antibodies to H-1, H-2, Le a, Le b, X, Y and precursor blood group determinants. Samples from 19 33 individuals co-expressed Le b and Y-determinants (secretors) and 6 33 co-expressed Le a and X-determinants (non-secretors). Erythrocytes of these individuals were typed Le (a− b+) and Le (a+ b−), respectively. In seven other salivas, only one specificity, either Le a, Le b, X or Y, was expressed and in one sample none of these determinants could be detected. Only one saliva sample expressed H-1 specificity and none expressed H-2 or type 1 precursor determinants. The absence of H-1 and H-2 structures in secretors and the resulting expression of difucosylated Le b and Y-structures is probably a tissue-specific trait of salivary gland secretions. The strict co-expression of Le b with Y and Le a with X-supports the conclusion that only one 2-O-fucosyl-galactose transferase, which can fucosylate both type 1 and type 2 chains, exists in salivary glands. The finding that a number of individuals expressed neither X-nor Y-specificities was unexpected in view of previous work showing that the 3-O-fucosyl N-acetylglucosamine transferase involved in forming this structure is a ubiquitous enzyme. The individualistic expression of blood group phenotypes in tissues should be considered when the altered expression of blood groups in malignancy and other diseases is studied.
