摘要目的 黏膜免疫可以诱导有效的黏膜和系统免疫反应,从而保护黏膜表面,是防止病原体在黏膜表面克隆并入侵的关键.但黏膜接种疫苗吸收效率低,黏膜免疫效果往往不理想,因此需要添加有效的黏膜免疫佐剂和载体系统来提高疫苗的效果.壳聚糖是一种被广泛应用的天然聚合物,无毒,具有生物粘附性和免疫调节作用,在黏膜免疫中作为佐剂和载体得到大量应用.

abstractsMucosal immunity can effectively induce both mucosal and systemic immune responses to protect mucosa against pathogens. In general, vaccines alone are not sufficiently taken up after mucosal administration and result in poor immune responses. Therefore, adjuvant/delivery systems are required to enhance the immune response. Chitosan is a natural polymer which exerts advantages as a adjuvant or vaccine carrier due to its bio-adhesive properties and immune-modulating activity. This review article focuses on mucosal immunization and chitosan as the mucosal vaccine adjuvant and carrier.
