MHC restriction — MHC restricted antigen recognition, or MHC restriction, refers to the fact that a given T cell will recognize a peptide antigen only when it is bound to a particular MHC molecule. Normally, as T cells are stimulated only in the presence of self… … Wikipedia
MHC restriction — the phenomenon of certain cell–cell interactions in the immune response occurring only between cells haploidentical for a major histocompatibility complex (MHC). Helper T cells are activated by antigen only when the antigen is “seen†in… … Medical dictionary
MHC-Restriktion — Die MHC Restriktion beschreibt, dass Antigene von T Lymphozyten nur dann erkannt werden können, wenn sie zuvor aufbereitet und auf spezifischen körpereigenen Rezeptoren, den vom Haupthistokompatibilitätskomplex (MHC) codierten Klasse I und Klasse … Deutsch Wikipedia
restriction — 1. The process with which foreign DNA that has been introduced into a prokaryotic cell becomes ineffective. 2. A limitation. asymmetric fetal growth r. normal fetal head size as a result of preferential shunting of blood to b … Medical dictionary
Major histocompatibility complex — The major histocompatibility complex (MHC) is a large genomic region or gene family found in most vertebrates that encodes MHC molecules. MHC molecules play an important role in the immune system and autoimmunity. Proteins are continually… … Wikipedia

altered self hypothesis — The hypothesis that the T cell receptor in MHC mediated phenomena recognizes a syngeneic MHC Class I or Class II molecule after modification by a virus or certain chemicals. See MHC restriction … Dictionary of molecular biology
class I antigens — major histocompatibility antigens found on virtually every cell except for human erythrocytes; they are found on molecules consisting of two noncovalently bound chains. One, a 44 kD polymorphic glycoprotein partially embedded in the cell membrane … Medical dictionary
antigen presenting cell — A cell that carries on its surface antigen bound to MCH Class I or Class II molecules, and presents the antigen in this context to T cells. Includes macrophages, endothelium, dendritic cells and Langerhans cells of the skin. See also MHC… … Dictionary of molecular biology
histocompatibility antigen — A set of plasmalemmal glycoproteins that are crucial for T cell recognition of antigens. Particularly the HLA system in humans and the H2 system in mice. There are two classes of histocompatibility antigens: (1) Class I; histocompatibility… … Dictionary of molecular biology
