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. ...
Antigen presenting cells: Cells that capture antigens by endo- orphagocytosis, process them into small peptides, display them at theirsurfacethrough MHC molecules and provide co-stimulation signals that act synergistically to activate antigen-specificT cells.Antigen presenting cellsinclude B cells, macro...

The meaning of ANTIGEN-PRESENTING CELL is any of various cells (such as a dendritic cell, macrophage, or B cell) that take up and process an antigen into a peptide fragment which when displayed at the cell surface in combination with a molecule of the ma
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...

Priming of T cells is a key event in vaccination, since it bears a decisive influence on the type and magnitude of the immune response. T-cell priming after mucosal immunization via the nasal route was studied by investigating the distribution of antigen-loaded antigen presenting cells (APCs) ...
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 ...
