在狗,以前的主要组织相容性复合体(MHC)I类基因的分析表明,一个单一的多态性位点,狗白细胞抗原(DLA)-88。虽然已报告了51个等位基因,但尚未对患病率进行估计。我们假设,在一个品种,DLA-88的多样性将受到限制,一个或多个显性等位基因可以被识别。因此,我们确定了47只金毛猎犬和39只拳击手的等位基因使用情况。在每个群体中,发现10个等位基因,4个是共享的。鉴定出7个新等位基因。DLA-88*05101和 *50801在金毛猎犬中占主导地位,而大多数拳击手携带 *03401。在这些品种中,DLA-88多态性是有限的,并且在很大程度上不重叠。高流行率等位基因的发现满足了研究犬CD 8 + T细胞应答的重要先决条件。
In the dog, previous analyses of major histocompatibility complex (MHC) class I genes suggest a single polymorphic locus, Dog Leukocyte Antigen (DLA)-88. While 51 alleles have been reported, estimates of prevalence have not been made. We hypothesized that, within a breed, DLA-88 diversity would be restricted, and one or more dominant alleles could be identified. Accordingly, we determined allele usage in 47 Golden Retrievers and 39 Boxers. In each population, 10 alleles were found; 4 were shared. Seven novel alleles were identified. DLA-88*05101 and *50801 predominated in Golden Retrievers, while most Boxers carried *03401. In these breeds DLA-88 polymorphisms are limited and largely non-overlapping. The finding of highly prevalent alleles fulfills an important prerequisite for studying canine CD8+ T-cell responses.
