粘膜表面参与防御致病微生物的机理,近来受到极大注意。许多致炎症因素是经过鼻咽、呼吸道、泌尿生殖系和胃肠道的粘膜进入人体。这些入口处的粘膜具有免疫性能的淋巴组织,对粘膜免疫系统起重要作用。鼻咽粘膜、扁桃体和腺样体,富有免疫性能组织。由于它们在解剖上的“守门”位置,这些组织与外界环境有比较密切与经常的接触,成为吸入或明下抗原首先接触的部位。此外,扁桃体淋巴样组织对免疫系统的发育亦有一定关系。本
The mechanism by which mucosal surfaces participate in the defense of pathogenic microorganisms has drawn great attention recently. Many inflammatory factors pass through the nasopharynx, respiratory tract, genitourinary tract, and gastrointestinal mucosa into the body. The mucosa at these entrances has lymphoid tissue with immune properties and plays an important role in the mucosal immune system. Nasopharyngeal mucosa, tonsils and adenoids, rich in immune performance of tissues. Because of their anatomical “gatekeeper” position, these tissues have relatively close and constant contact with the external environment and become the first place where the antigen is inhaled or exposed. In addition, tonsil lymphoid tissue has a relationship with the development of the immune system. this
