Antigen processing, or the cytosolic pathway, is an immunological process that prepares antigens for presentation to special cells of the immune system called T lymphocytes. It is considered to be a stage of antigen presentation pathways.
A radioimmunoassay (RIA) is an immunoassay that uses radiolabeled molecules in a stepwise formation of immune complexes.A RIA is a very sensitive in vitro assay technique used to measure concentrations of substances, usually measuring antigen concentrations (for example, hormone levels in blood) by use of antibodies.
Transporter associated with antigen processing 1 (TAP1) is a protein that in humans is encoded by the TAP1 gene. A member of the ATP-binding cassette transporter family, it is also known as ABCB2. [ 5 ] [ 6 ]
The pathway involved in specific cases is dictated by intrinsic and extrinsic factors of allograft and directly influence nature and magnitude of T lymphocytes mediated immune response. Furthermore, variant tissues and organs such as skin or cornea or solid organ transplants can be recognized in different pathways and therefore are rejected in ...
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 can be recognized by a T-cell receptor.
Alloimmunity (sometimes called isoimmunity) is an immune response to nonself antigens from members of the same species, which are called alloantigens or isoantigens.Two major types of alloantigens are blood group antigens [1] and histocompatibility antigens.
Transporter associated with antigen processing (TAP) protein complex belongs to the ATP-binding-cassette transporter family. [1] It delivers cytosolic peptides into the endoplasmic reticulum (ER), where they bind to nascent MHC class I molecules.
Pathway resources and types of pathway analysis using databases like KEGG, Reactome and WikiPathways. [1]Pathway is the term from molecular biology for a curated schematic representation of a well characterized segment of the molecular physiological machinery, such as a metabolic pathway describing an enzymatic process within a cell or tissue or a signaling pathway model representing a ...
