The Kiwifruit Information Resource (KIR) is dedicated to maintain and integrate comprehensive datasets on genomics, functional genomics and transcriptomics of kiwifruit (Actinidiaceae). KIR serves as a central access point for existing/new genomic and genetic data. KIR also provides researchers with a variety of visualization and analysis tools. Current developments include the updated genome s...

Inwardly rectifying K(+) (Kir) channels allow K(+) to move more easily into rather than out of the cell. They have diverse physiological functions depending on their type and their location. There are seven Kir channel subfamilies that can be classified into four functional groups: classical Kir channels (Kir2.x) are constitutively active, G protein-gated Kir channels (Kir3.x) are regulated by ...

Interactions between killer cell immunoglobulin-like receptors (KIRs) and human leukocyte antigen (HLA) class I ligands regulate the development and response of human natural killer (NK) cells. Natural selection drove an allele-level group A KIR haplotype and the HLA-C1 ligand to unusually high frequency in the Japanese, who provide a particularly informative population for investigating the me...

Ly49 lectin-like receptors and killer cell Ig-like receptors (KIR) are structurally unrelated cell surface glycoproteins that evolved independently to function as diverse NK cell receptors for MHC class I molecules. Comparison of primates and various domesticated animals has shown that species have either a diverse Ly49 or KIR gene family, but not both. In four pinniped species of wild marine c...

It has been established that hematopoietic chimerism after double umbilical cord blood transplantation (dUCBT) can predict disease relapse and detect potential engraftment failure. The use of a precise method to evaluate residual host hematopoiesis is imperative because it has been reported that the risk of relapse is higher in patients with mixed chimerism. Up to now, real-time quantitative po...

The aim of this study was to explore the genetic polymorphism, genotype, and haplotype characteristics of the KIR locus in the Xinjiang Han population in order to establish a foundation for future analysis of the relationship between KIR genes and disease. KIR genes were detected by sequence-specific primer-polymerase chain reaction in 184 randomly selected, healthy individuals from the Han pop...

We analyzed killer cell immunoglobulin-like receptor (KIR) gene polymorphisms and genotype and haplotype characteristics in the Uygur population, a non-nomadic ethnic group found in Xinjiang, China, to provide a basis for studies on relationships between KIRs and diseases in this group. Sequence-specific primer PCR was used to detect the KIR gene in 84 Uygur individuals. A standard genotype and...

BACKGROUND The variability in the association of host innate immune response to Hepatitis C virus (HCV) infection requires ruling out the possible role of host KIR and HLA genotypes in HCV-related disorders: therefore, we therefore explored the relationships between KIR/HLA genotypes and chronic HCV infection (CHC) as they relate to the risk of HCV-related hepatocarcinoma (HCC) or lymphoprolife...

The etiology of common idiopathic epileptic syndromes is genetically determined, but the complex pattern of inheritance suggests an epistatic interaction of several susceptibility genes. Mutations in over 70 genes now define biological pathways leading to rare monogenic forms of epilepsy in humans and animals. Recognizing the molecular basis of an ion-channel disease has provided new opportunit...
