只有某些特定的细胞可以表达MHC I类和II类分子、协同刺激信号分子和各种粘附分子,这就是我们今天这期推送所要介绍的主角——抗原呈递细胞(Antigen-presenting cells, APC)。 ▉ 抗原呈递细胞 抗原呈递细胞(APC)的工作职责就是激活CTL和...
The inherent tolerogenicity of the liver and its role in the regulation of innate and adaptive immunity are mediated by parenchymal and non-parenchymal antigen-presenting cells (APCs), cell-autonomous molecular pathways and locally produced factors. Here, we review the central role of liver APCs ...
2.Dendritic cell ( DC ) is the most powerful professional antigen - presenting cell. 树突状细胞 ( DC ) 是具有最强抗原提呈能力的专职性抗原提呈细胞. 3.Dendritic cells - antigen presenting cell, which has special function in activating T cells and inducing immune reaction. ...
T cells mature after they accept antigens from antigen presenting cells (APC). Lymphocytes are a very important part of the lymphatic system, which could not function without these soldier cells. Immune organs are spread throughout the entire body. Without lymphocytes, the immune system could ...
Antigen presenting cells[南开大学2014研] 相关知识点: 试题来源: 解析 答案:Antigen presenting cells即抗原呈递细胞(APC),抗原提呈细胞是指具有摄取、处理抗原并将抗原信息提呈给T淋巴细胞的一类细胞,又称为辅佐细胞。在机体的免疫识别、免疫应答与免疫调节中起重要作用。 解析:空...

Antigen-presenting cells (APCs) are a heterogeneous group of immune cells that mediate the cellular immune response by processing and presenting antigens for recognition by certain lymphocytes such as T cells. Classical APCs include dendritic cells, macrophages, Langerhans cells and B cells. ...
Provided herein is the discovery of a novel mechanism by which the ability of antigen presenting cells to stimulate T-cell function is inhibited by the formation of immunosuppresive complexes comprising the antigen presenting cell membrane-associated βglycan and cytokine TGF-β. Also provided are me...
