Dendritic cells have been isolated from human tonsillar tissue and shown to act as accessory cells in a mitogenic response. The dendritic cells will induced receptors for the active metabolite of vitamin D3, 1,25(OH)2D3, in the responder E+ T cells. The dendritic cells themselves constitutively express receptors for the metabolite, and this distinguishes them from other non-T cells in lymphomedullary tissue. Expression of the 1,25(OH)2D3 receptor may be a dendritic cell property that facilitates their accessory cell role within the tissue microenvironment.
树突状细胞已从人扁桃体组织中分离出来,并被证明在促有丝分裂反应中作为辅助细胞发挥作用。树突状细胞会在反应性E + T细胞中诱导维生素D3的活性代谢物1,25(OH)2D3的受体。树突状细胞本身组成性地表达该代谢物的受体,这使其与淋巴髓组织中的其他非T细胞区分开来。1,25(OH)2D3受体的表达可能是树突状细胞的一种特性,有助于它们在组织微环境中发挥辅助细胞的作用。
