The PD-1 pathway, consisting of the co-inhibitory receptor PD-1 on T cells and its ligand (PD-L1) on antigen-presenting cells (APCs), is a major mechanism of tumor immune evasion. PD-1 and PD-L1 blockade antibodies have produced remarkable clinical activities against a subset of cancers. Many cell types, including both hematopoietic cells and nonhematopoietic cells (eg, endothelial cells), may participate in the process of antigen presentation with varying levels of efficiency. 26,27 Professional APCs are hematopoietic cells that have a specialized role in processing and presenting antigens and do so with an effectiveness that is above the threshold required to promote an Antigens & the Immune System.

Antigen presenting cells

From: Immunology Guidebook, 2004 An antigen-presenting cell (APC) is an immune cell that detects, engulfs, and informs the adaptive immune response about an infection. When a pathogen is detected, these APCs will phagocytose the pathogen and digest it to form many different fragments of the antigen. antigen-presenting cell A cell, such as a macrophage, a B cell or a dendritic cell, that presents processed antigenic peptides and MHC class II molecules to the T cell receptor on CD4 T cells.

MHC class I and class II molecules are similar in function: they deliver short peptides to the cell surface allowing these peptides to be recognised by CD8+ (cytotoxic) and CD4+ (helper) T cells, respectively. The innate immune activation was transient and resulted in priming of H10-specific CD4 + T cells exclusively in the vaccine-draining LNs. Antigen-presenting cells (APCs) include dendritic cells, macrophages, and B-lymphocytes. APCs express both MHC-I and MHC-II molecules and serve two major functions during adaptive immunity: they capture and process antigens for presentation to T-lymphocytes, and they produce signals required for the proliferation and differentiation of lymphocytes. Le cellule APC (cellule che presentano l'antigene, dall'inglese Antigen-Presenting Cell) sono una classe di cellule del sistema immunitario in grado di esporre antigeni sulla propria superficie di membrana attraverso l'MHC di classe II. An antigen-presenting cell (APC) can be defined as any cell that expresses MHC or related molecules (e.g., CD1) that bind antigenic components such as peptides, and can be recognized by one class of T cell or another.

APCs process antigens and present them to T-cells. An antigen-presenting cell (APC) is an immune cell that detects, engulfs, and informs the adaptive immune response about an infection. When a pathogen is detected, these APCs will phagocytose the pathogen and digest it to form many different fragments of the antigen. Antigen-presenting cells (APCs) are a large group of various cells that trigger the cellular immune response by processing an antigen and exposing it in a form recognizable by T cells in the process known as antigen presentation.

Antigen Presenting Cells (APCs) are cells that capture antigens from within the body, and present them to naive T-cells. Many immune system cells can present antigens, but the most common types are macrophages and dendritic cells, which are two types of terminally differentiated leukocytes that arise from monocytes. Antigen-presenting cells (APCs) include dendritic cells, macrophages, and B-lymphocytes. An antigen-presenting cell (APC) can be defined as any cell that expresses MHC or related molecules (e.g., CD1) that bind antigenic components such as peptides, and can be recognized by one class of T cell or another. Antigen-presenting cell definition 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 major histocompatibility complex is recognized by and serves to activate cells of the immune system (such as helper T cells or cytotoxic T cells To facilitate the therapeutic application of antigen-presenting cells (APCs), we have developed a cell-based artificial APC (aAPC) system by engineering K562 cells with lentiviruses to direct the stable expression and secretion of a variety of co-stimulatory molecules and cytokines.

In order to define an antigen-presenting cell, it's helpful to first define an antigen. An antigen is anything that starts, or generates, an immune response. They're Professional antigen presenting cells (APCs) are immune cells that specialize in presenting an antigen to a T-cell. The main types of professional APCs are dendritic cells (DC), macrophages, and B cells.

An antigen-presenting cell (APC) or accessory cell is a cell that displays antigen complexed with major histocompatibility complexes (MHCs) on their surfaces; this process is known as antigen presentation.

Kular, Peptidyl An antigen-presenting cell (APC) is an immune cell that detects, engulfs, and informs the adaptive immune response about an infection.
