树突状细胞(DC)是迄今所知的功能最强的抗原提呈细胞,是固有免疫和适应性免疫的桥梁和纽带,主要参与细胞免疫和T细胞依赖的体液免疫反应,在免疫反应中处于中心位置。多糖作为一种生物免疫应答调节剂,对DC功能的影响近年来有所报道,主要包括多糖对DC表面分子的表达、细胞因子的分泌、吞噬功能、抗肿瘤免疫、多糖受体以及信号转导途径等方面的调节作用。 Dendritic cells (DCs) are by far the most potent antigen-presenting cells and are the bridge and link between innate and adaptive immunity. They are mainly involved in cellular immunity and T cell-dependent humoral immune response. In the immune response In the center. Polysaccharides as a biological immune response regulator, on the DC function has been reported in recent years, including polysaccharide on the surface of DC molecules expression, secretion of cytokines, phagocytosis, anti-tumor immunity, polysaccharide receptors and signal transduction Ways and other aspects of the regulatory role.
