The evolution of natural killer cell receptors.
Utrecht, Netherlands. In Immunogenetics, Jan 2016
Here, we review the expansion of NKR receptor families in different mammal species, and we discuss several hypotheses that possibly underlie the diversification of the NK cell receptor complex, including the evolution of viral decoys, peptide sensitivity, and selective MHC-downregulation.
Antigen-specific NK cell memory in rhesus macaques.
Boston, United States. In Nat Immunol, Sep 2015
We found that splenic and hepatic NK cells from SHIV(SF162P3)-infected and SIV(mac251)-infected macaques specifically lysed Gag- and Env-pulsed dendritic cells in an NKG2-dependent fashion, in contrast to NK cells from uninfected macaques.
Co-evolution of NK receptors and HLA ligands in humans is driven by reproduction.
Cambridge, United Kingdom. In Immunol Rev, Sep 2015
Invading placental trophoblast cells express human leukocyte antigen class I ligands (HLA-E, HLA-G, and HLA-C) for receptors on maternal uterine natural killer (NK) and myelomonocytic cells, CD94/NKG2, leukocyte immunoglobulin-like receptor (LILR), and killer immunoglobulin receptor (KIR).
NK cells: tuned by peptide?
Columbus, United States. In Immunol Rev, Sep 2015
Similarly, the conservation of the NKG2 family of receptors parallels the conservation of MHC-E, the ligand for CD94:NKG2A/C/E.
