呼吸道局部的免疫是消除进入呼吸道有害物质及微生物病原的主要环节。就目前看法,它不仅反应了机体全身的免疫状态,还具有相对的独立性。因此,研究呼吸道局部的免疫机制对于有效地预防和治疗呼吸道感染十分重要,本文重点介绍呼吸道局部的免疫功能。与全身性免疫机制一样,支气管肺部的免疫机制亦分为特异性和非特导性二种(表1)。
Local respiratory tract immunity is to eliminate the main part of the respiratory tract into harmful substances and microbial pathogens. The current view, it not only reflects the body’s immune status, but also has the relative independence. Therefore, studying the local immune mechanism of the respiratory tract is very important for the effective prevention and treatment of respiratory infections. This article focuses on the local immune function of the respiratory tract. As with systemic immune mechanisms, the immune mechanisms of the bronchial lungs are also classified into two types, specific and non-specific (Table 1).
