在咽鼓管内有两种糖结合物,一种是分泌性的(粘蛋白),另一种是膜结合性的。它们是粘膜纤毛传输系统的重要结构成分,在保护咽鼓管上皮、抵御细菌和病毒侵犯方面发挥重要作用。上皮细胞与入侵病原体之间的作用是通过糖结合物的碳水化合物受体中介的。许多研究表明,细菌或病毒通过 There are two types of carbohydrate conjugates in the Eustachian tube, one is secreted (mucins) and the other is membrane-bound. They are important structural components of the mucociliary transport system and play an important role in protecting the eustachian tube epithelium against bacterial and viral encroachments. The role of epithelial cells and invading pathogens is mediated by the carbohydrate receptors of the carbohydrate conjugates. Many studies show that bacteria or viruses pass through
