There are many complex mechanisms employed by the immune system to destroy invading organisms, abnormal cells and contain infections in order to maintain health and life. Antigen presenting cells (APC) are some of the cells that form part of these mechanisms.

Microdomains in the membrane landscape shape antigen-presenting cell function Malou Zuidscherwoude, Charlotte M. de Winde, Alessandra Cambi, and Annemiek B. van Spriel 1 Department of Tumor Immunology, Nijmegen Centre for Molecular Life Sciences, Radboud University Medical Centre 1980-08-01 The cells that perform these functions are antigen-presenting cells (APCs). Most nucleated cells express at least some of the major histocompatibility complex (MHC) proteins required to present antigens to T cells, a feature that endows all cells with the potential to become targets of the immune response when damaged or infected. Modulating T Cell Responses via Autophagy: The Intrinsic Influence Controlling the Function of Both Antigen-Presenting Cells and T Cells Seth D. Merkley 1 , Cameron J. Chock 2 , Xuexian O. Yang 2,3 , James Harris 4 and Eliseo F. Castillo 1,3,5 * APCs play a pivotal role in cellular immunity by processing and presenting antigens to specific T cells. 14 Within the immune synapse formed between APCs and T cells, 3 signals are required for antigen-specific T-cell activation. 18 The first signal is provided by antigen peptide–MHC I and peptide–MHC II complexes on the surface of APCs through T-cell receptor to activate CD8 + and CD4 + T 2013-08-01 Donate here: http://www.aklectures.com/donate.phpWebsite video link: http://www.aklectures.com/lecture/antigen-presenting-cells-macrophages-dendritic-cells-a In in vitro experiments, eosinophils can process antigen and express the costimulatory molecules, and after cytokine‐elicited induction of MHC‐II, expression can function as antigen‐presenting cells in stimulating T lymphocyte responses. 2020-02-07 How professional antigen presenting cells present parts of engulfed pathogens on MHC II complexes.

Furthermore, antigen-presenting cells (APCs) derived from the mutant mice revealed an impaired intrinsic APC function, demonstrating the importance of OX40L in both the priming and effector phases of T cell activation.

Antigen presentation is a vital immune process that is essential for T cell immune response triggering. Because T cells recognize only fragmented antigens displayed on cell surfaces, antigen processing must occur before the antigen fragment, now bound to the major histocompatibility complex (MHC), is transported to the surface of the cell, a process known as presentation, where it can be recognized by a T-cell receptor.

The T-cell functions, including cytokine production, expansion, and survival, av C Guenther · 2020 — synapse formation between antigen presenting cells and T-cells. involved in integrin-mediated dendritic cell programming and function.

The impaired T cell priming was also accompanied by a concomitant reduction of both T helper type 1 (Th1) and Th2 cytokines. Furthermore, antigen-presenting cells (APCs) derived from the mutant mice revealed an impaired intrinsic APC function, demonstrating the importance of OX40L in both the priming and effector phases of T cell activation.

Several cytokines are produced in RA synovium, including TNFα, IL-1 and granulocyte macrophage-colony stimulating factor, that can upregulate the ability of DCs to present antigen.

Antigen presentation allows for specificity of adaptive immunity and can contribute to immune responses against both intracellular and extracellular pathogens. 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. Cell.
