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...
Related to Antigen-presenting cells:perforin,Dendritic cells an·ti·gen (ăn′tĭ-jən)alsoan·ti·gene(-jēn′) n. A molecule that is capable of binding to an antibody or to an antigen receptor on a T cell, especially one that induces an immune response. An antigen is usually a...
Antigen presenting cells include macrophages and dendritic cells. They are phagocytes that consume pathogens and then process those pathogens to find antigens. The antigens are then combined in an MHC protein complex and presented to T cells. T cells are then activated. What cells become APC?
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. ...

Regulatory T cell differentiation of thymocytes does not require a dedicated antigen-presenting cell but is under T cell-intrinsic developmental control The majority of regulatory T cells ($T_{regs} $) are believed to be of thymic origin. It has been hypothesized that this may result from uniqu...
