Killer cell immunoglobulin-like receptor (KIR) genes encode for activating and inhibitory surface receptors, which are correlated with the regulation of Natural Killer (NK) cell cytotoxic activity. Reduced NK cell cytotoxic activity has been consistently reported in Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME) patients, and KIR haplotypes and allelic polymorphism remain to be inv...
Although the KIR gene content polymorphism has been studied worldwide, only a few isolated or Amerindian populations have been analyzed. This extremely diverse gene family codifies receptors that are expressed mainly in NK cells and bind HLA class I molecules. KIR-HLA combinations have been associated to several diseases and population studies are important to comprehend their evolution and the...
BACKGROUND KIR genes coding for natural killer cell immunoglobulin-like receptors, KIR, influence the effector and regulatory function of NK cells as well as some subpopulations of T lymphocytes (e.g. CD4+CD28-KIR+) depending on presence of ligands (particularly HLA-C molecules). KIR-KIR ligand interaction may lead to the development of autoimmune disorders, including rheumatoid arthritis (RA)....
Mammary glands are physiologically active in female mammals only during nursing. Immediately after weaning, most lactation-related genes are downregulated and milk production ceases. In our previous study, we have detected an inwardly rectifying potassium channel (Kir) 2.1-like current in mammary secretory (MS) cells freshly isolated from lactating mice. This current is highly sensitive to exte...
1. In the vertebrate retina, the inwardly rectifying K+ (KIR) channels of the Müller (glial) cells are pathways for the redistribution of excess extracellular K+. Due to this role in K+ homeostasis, the activity of Müller cell KIR channels is likely to have significant functional consequences for the retina. In this study we asked whether intracellular ATP regulates the function of KIR channels...
BACKGROUND Allogeneic hematopoietic cell transplantation (HCT) can be curative for many hematologic diseases. However, complications such as graft-versus-host disease (GVHD) and relapse of primary malignancy remain significant and are the leading causes of morbidity and mortality. Effects of killer Ig-like receptors (KIR)-influenced NK cells on HCT outcomes have been extensively pursued over th...
The function of inwardly rectifying K+ (Kir) channels is highly diverse and therefore is tightly regulated by various environmental factors. In their article in this issue of Neuron, Rapedius et al. recognize a conserved structural mechanism for Kir channels gating by both pH and PIP2. In light of these findings and accumulated knowledge, PIP2 is suggested to have a common coregulatory role in ...
OBJECTIVE The genes for killer-cell immunoglobulin-like receptors (KIRs) have been cloned and their functions and expression in patients with rheumatoid arthritis (RA) have been partially clarified. However, the correlation between their expression and disease activity has not been analyzed in patients with RA. Thus, we measured KIR expression on lymphocytes in patients with RA, and assessed th...
Killer Ig-like receptors (KIRs) are implicated in protection from multiple pathogens including HIV, human papillomavirus, and malaria. Nonhuman primates such as rhesus and cynomolgus macaques are important models for the study of human pathogens; however, KIR genetics in nonhuman primates are poorly defined. Understanding KIR allelic diversity and genomic organization are essential prerequisite...
