MR1 presentation of vitamin B-based metabolite ligands.
Melbourne, Australia. In Curr Opin Immunol, Feb 2015
UNASSIGNED: The major histocompatibility complex class I-related molecule MR1 can bind a novel class of antigens, namely a family of related small organic vitamin B metabolites.
Activation and Function of iNKT and MAIT Cells.
Los Angeles, United States. In Adv Immunol, Dec 2014
First, their cognate antigens are presented by nonclassical class I antigen-presenting molecules; CD1d for iNKT cells and MR1 for MAIT cells.
Adoptive T Cell Therapy Targeting CD1 and MR1.
Toronto, Canada. In Front Immunol, Dec 2014
CD1 and MR1 are class I-like monomorphic molecules and their restricted T cells possess unique T cell receptor specificity against entirely different classes of antigens.
Biology of CD1- and MR1-restricted T cells.
Oxford, United Kingdom. In Annu Rev Immunol, 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.
Butyrophilin 3A1 binds phosphorylated antigens and stimulates human γδ T cells.
Basel, Switzerland. In Nat Immunol, 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.
