Major histocompatibility complex, class I-related

MR1, major histocompatibility complex class I-related
This gene is thought to play a role in the regulation of myofibrillogenesis. Mutations in this gene have been associated with the movement disorder paroxysmal non-kinesigenic dyskinesia. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2010] (from NCBI)

MAIT cells are depleted early but retain functional cytokine expression in HIV infection.
Kent et al., Melbourne, Australia. In Immunol Cell Biol, 28 Nov 2014
We studied longitudinal blood samples from 31 HIV-infected subjects for MAIT cell numbers, phenotype and function using both standard Vα7.2/CD161 surface markers and an MR1 tetramer.

Human T cells use CD1 and MR1 to recognize lipids and small molecules.
Moody et al., Boston, United States. In Curr Opin Chem Biol, 27 Oct 2014
Newer insights into αβ and γδ T cell activation by CD1 or MR1 proteins greatly expand the biochemical range of T cell antigens to include lipids and non-peptidic small molecules.
T-cell activation by transitory neo-antigens derived from distinct microbial pathways.
McCluskey et al., Melbourne, Australia. In Nature, Jun 2014
However, the genesis of these small organic molecules and their mode of presentation to MAIT cells by the major histocompatibility complex (MHC)-related protein MR1 (ref.
MAITs, MR1 and vitamin B metabolites.
Rossjohn et al., Australia. In Curr Opin Immunol, Feb 2014
Recently the antigenic repertoire of αβT-cells has been expanded with the observation that mucosal-associated invariant T-cells (MAIT cells), an abundant population of innate-like T-cells, can recognise metabolites of vitamin B, when presented by the MHC-related protein, MR1.
Modeling T cell receptor recognition of CD1-lipid and MR1-metabolite complexes.
Weng et al., Worcester, United States. In Bmc Bioinformatics, Dec 2013
BACKGROUND: T cell receptors (TCRs) can recognize diverse lipid and metabolite antigens presented by MHC-like molecules CD1 and MR1, and the molecular basis of many of these interactions has not been determined.
Biology of CD1- and MR1-restricted T cells.
Cerundolo et al., Oxford, United Kingdom. In Annu Rev Immunol, Dec 2013
In this review, we describe the most recent events in the field, with particular emphasis on (a) structural and functional aspects of lipid presentation by CD1 molecules, (b) the development of CD1d-restricted invariant natural killer T (iNKT) cells and transcription factors required for their differentiation, (c) the ability of iNKT cells to modulate innate and adaptive immune responses through their cross talk with lymphoid and myeloid cells, and (d) MR1-restricted and group I (CD1a, CD1b, and CD1c)-restricted T cells.
[MAIT cells in autoimmunity].
Miyake, In Nihon Rinsho Meneki Gakkai Kaishi, Dec 2013
They are restricted by a nonpolymorphic MHC-related molecule-1 (MR1), and cells are selected in the thymus.
Mucosal-associated invariant T-cells: new players in anti-bacterial immunity.
Willberg et al., Oxford, United Kingdom. In Front Immunol, Dec 2013
MR1 has recently been shown to present an unstable pyrimidine intermediate derived from a biosynthetic precursor of riboflavin; riboflavin biosynthesis occurs in many bacteria but not in human beings.

The major histocompatibility complex class I-related antigens A (MICA) are polymorphic.
Butyrophilin 3A1 binds phosphorylated antigens and stimulates human γδ T cells.
De Libero et al., Basel, Switzerland. In Nat Immunol, Sep 2013
Human T cells that express a T cell antigen receptor (TCR) containing γ-chain variable region 9 and δ-chain variable region 2 (Vγ9Vδ2) recognize phosphorylated prenyl metabolites as antigens in the presence of antigen-presenting cells but independently of major histocompatibility complex (MHC), the MHC class I-related molecule MR1 and antigen-presenting CD1 molecules.

Lewinsohn et al., Portland, United States. In Nat Rev Microbiol, 2013
The semi-invariant antigen recognition receptor of MAIT cells detects the non-polymorphic antigen-presenting molecule major histocompatibility complex class I-related protein 1 (MR1), which can bind microorganism-derived riboflavin metabolites.
MR1 presents microbial vitamin B metabolites to MAIT cells.
McCluskey et al., Melbourne, Australia. In Nature, 2012
Mucosal-associated invariant T (MAIT) cells are an abundant population of innate-like T cells in humans that are activated by an antigen(s) bound to the MHC class I-like molecule MR1.
