树突状细胞(DCS)是重要的抗原递呈细胞,其参与免疫应答的机制十分复杂,首先要形成“三力子复合体”,加上 DCs表达的其他刺激因子和粘附分子等信号的传递才能完成。DCs尚有一些其他功能,如表达IgE受体或作为感觉受体等,具有其他非职业性APC有明显不同 Dendritic cells (DCSs) are important antigen-presenting cells and their mechanism of participation in immune response is very complex. First of all, it is necessary to form “triple force subtype” and add other stimuli and adhesion molecules expressed by DCs Delivery can be done. DCs still have a number of other functions, such as the expression of IgE receptors or as sensory receptors, etc., which are significantly different from other non-occupational APCs
