项目摘要
In murine digestive tract, glycolipids were differentially distributed in the different regions, i.e. the globo-series glycolipids including Forssman antigens in the mesenchymal regions and the ganglio-series glycolipids in the epithelial regions. Under germ-free condition, Gg_4Cer was the dominant glycolipid in the epithelia of duodenum, jejunum and ileum, but IV^2Fuα-Gg_4Cer became the major one after transfer of mice to the conventional breeding condition. However, the gastric and colonic epithelia contained GM1, fucosyl GMl, Gg_4cer and IV^2Fucα-Gg_4Cer, whose amounts were not affected by the breeding conditions. The gene responsible for fucosylation of Gg_4Cer in the digestive tract was characterized to be Fut-2 by targeted deletion of Fut-1 and Fut-2 genes. Also, although fucosylated glycolipids were completely eliminated from the stomach, caecum and colon of Fut-2-null mice, they were detected in the small intestine, indicating the alterative utilization of Fut-1 gene in the small intestine.Since Gg_4Cer is known to be the receptor of Lactobacillus, antibodies against L. johnsonii and L .intestinalis were generated to determine the binding ability of glycolipids and the number of bacteria in the different region of digestive tract. The antibodies reacted with teichoic acid in the cell wall of bacteria and with Gg_4Cer in the digestive tract, indicating the possible involvement of bacterial infection in the onset and progress of human disease with anti-Gg_4Cer antibodies, such as Beret disease, and that careful application of antibodies is required for the binding analysis of bacteria with Gg_4Cer.
在鼠消化道中,糖脂分布在不同区域,即在间充质区域中的诱捕者抗原,以及上皮区域中的Globo系列糖脂。在无菌条件下,gg_4cer是十二指肠,空肠和回肠上皮中的主要糖脂,但是iv^2fuα-gg_4cer在将小鼠转移到常规育种条件下后成为主要的糖脂。然而,胃上皮包含GM1,Fucosyl GML,GG_4Cer和IV^2fucα-GG_4Cer,其数量不受育种条件的影响。负责消化系统中GG_4Cer的岩藻糖基化的基因被定为FUT-1和FUT-2基因的靶向缺失为FUT-2。同样,尽管ft-2-null小鼠的stallch,Caecum和结肠完全消除了诱导的糖脂,但在小肠中检测到它们,表明在小肠中使用fut-1基因的替代化利用是gg_4cer的。糖脂的能力和消化道不同区域中细菌的数量。与细菌细胞壁和gg_4cer在消化道中的细胞壁中反应的抗体,表明细菌感染可能参与人类疾病的发作和进展中,抗gg_4cer抗体,例如贝雷症抗体,例如贝雷症抗体,以及对抗体进行抗体的应用,以将抗体应用于Bacteria的结合分析中。
