Cutting edge: molecular cloning of a killer cell Ig-like receptor in the mouse and rat.

Inhibitory Killer Cell Immunoglobulin-Like Receptor KIR3DL1 in Combination with HLA-B Bw4iso Protect against Ankylosing Spondylitis

Background: The HLA class I molecules serve as ligands for both T cell receptors and killer cell immunoglobulin-like receptors (KIRs). Objective: We investigated the HLAC and HLA-Bw4 alleles as well as KIRs expression on CD56 positive lymphocytes to evaluate whether these genes and molecules could influence Ankylosing spondylitis (AS) susceptibility, alone or in combination. Methods: We typed 4...

Killer Cell Immunoglobulin-Like Receptors Influence the Innate and Adaptive Immune Responses

Natural killer (NK) cells are a subset of lymphocytes which play a crucial role in early innate immune response against infection and tumor transformation. Furthermore, they secrete interferon-γ (IFN-γ) and tumor necrosis factor (TNF) prompting adaptive immu-nity. NK cells distinguish the unhealthy cells from the healthy ones through an array of cell-surface receptors. Human NK cells use inhibi...

Psoriatic Arthritis and Killer Ig-Like Receptor Combinations in Protection/Susceptibility Conferred by HLA Autoimmune Disease: Hierarchy of Cutting Edge: Heterozygote Advantage in

Molecular Cloning and Mutagenesis of Rat Glucocerebrosidase Gene

Purpose: The aim of this study was cloning the Gba enzyme in pUCBM21 plasmid, and making frame mutation on it and sequencing it. Materials and methods: mRNA was extracted from mouse spleen and glucocerebrosidase cDNA was synthesized and amplified by PCR with specific primers. cDNA was cloned in pUCBM21 and analyzed by restriction enzymes. A fragment of its sequence was deleted using MscI restr...

Cutting edge: selective expression of inhibitory or activating killer cell Ig-like receptors in circulating CD4+ T lymphocytes.

Apart from NK cells, TCRgammadelta and CD8+ T cells, killer cell Ig-like receptor (KIR) expression was described on a minor subset of CD4+ T cells. However, their functions remain to be elucidated in this latter lymphocyte population. We demonstrated that KIR2DL2/L3 (CD158b) and KIR2DS2 (CD158j) transcripts were synthesized by sorted CD4+CD158b/j+ T cells obtained from healthy individuals. In c...
