近年来,随着免疫学的发展,消化道的免疫与消化道疾病的关系日渐为人们所重视,本文就此作一综述。消化道的免疫系统一、消化道非特异性免疫消化道非特异性免疫包括:从口腔到直肠全消化道的粘膜屏障、各种分解酶、胆盐、肝屏障、胃肠道的蠕动及天然的细菌丛。消化道粘膜上皮细胞分泌的粘蛋白能防止微生物病原体附着在粘膜表面并通过唾液、肠液的冲洗,有效地清除病毒、细菌。粘蛋白且可与肠
In recent years, with the development of immunology, the relationship between the digestive tract immunity and gastrointestinal diseases has been paid more and more attention by people. This article reviews this issue. Immune system of the digestive tract First, non-specific immune digestive tract non-specific immune Immune tract including: from the mouth to the rectum of the digestive tract mucosal barrier, a variety of enzymes, bile salts, liver barrier, gastrointestinal motility and natural bacteria Cong Mucin secretion secreted mucosal epithelial mucus can prevent microbial pathogens attached to the mucosal surface and through the saliva, intestinal fluid washing, effectively remove viruses and bacteria. Mucin and can be with the intestine
