非免疫和免疫因素对鼻和鼻窦感染的预防均重要。非免疫屏障由如下几方面组成:(a)粘膜纤毛排运系统;(b)抗微生物因子(溶菌酶,乳铁蛋白,过氧化物,蛋白酶,干扰素等);(c)吞噬细胞(嗜中性白细胞,巨噬细胞)。防御系统的免疫和非免疫部分,通常协同发挥作用。例如,当特异性抗体存在,白细胞吞噬微生物能力增加。体液免疫系统是鼻腔免疫屏障不可分割的组成部分,已有大量文献详叙。本文可从鼻腔白细胞亚群的研究结果,探讨免疫系统与感冒和鼻窦炎的关系。【人类鼻腔呼吸道粘膜中的淋巴白细胞亚群】与浆细胞、免疫球蛋白、抗体相比,鼻腔 Prevention of nasal and sinus infections is important for both non-immune and immune factors. The non-immune barrier is composed of: (a) mucociliary drainage system; (b) antimicrobial factors (lysozyme, lactoferrin, peroxide, protease, interferon, etc.); Neutrophils, Macrophages). The immune and non-immune components of defense systems often work together. For example, leukocytes phagocytose microorganisms with increased capacity in the presence of specific antibodies. The humoral immune system is an integral part of the nasal immune barrier and has been extensively documented. This article from the nasal leukocyte subsets of the research results to explore the immune system and the relationship between cold and sinusitis.
