Apart from presenting peptides to T cells, class I HLA molecules serve as ligands for killer cell immunoglobulin‐like receptor (KIRs) and regulate the response of natural killer (NK) cells. The role played by HLA and KIR in the acute rejection (AR) following liver transplantation has been controversial. In this retrospective study, we assessed the influence of class I HLA alleles, HLA matching between...
The inhibitory KIR3DL1 and the activating KIR3DS1 segregate as alleles of the same locus. KIR3DL1 is highly diversified at the allele level and KIR3DL1 alleles exhibit varied levels of expression and ligand binding affinity resulting in varied degrees of NK cell inhibition. Previous studies have shown that the KIR3DL1/3DS1 polymorphism associated with viral infection, cancer and transplantation. However,...
KIR and their HLA ligands are encoded by two of the most diverse gene families in the human genome. The function of KIR on the NK cell is highly dependent on the normal expression of class I HLA on the target cell. Previous population studies in southern Chinese have been focused on the KIR framework genes and genotypes but little is known about the compound profiles of KIR/HLA. The present study...
