KIR-HLA combinations and susceptibility to tuberculosis
Introduction: Tuberculosis (TB), caused by Mycobacterium Tuberculosis (Mtb), with more than nine million new cases and almost two million deaths in each year is a worldwide important public health problem. Generally, human immune responses prevent Mtb spread, and the infection remains in a latent state. Both, innate and adaptive immune responses are involved against TB. However, the role of the...
متن کاملارتباط برهمکنشهای KIR-HLA با بیماریها
The killer cell immunoglobulin-like receptors (KIR) are a recently discovered family of activating and inhibitory receptors which control natural killer (NK) cell function. KIR exist as a diverse family of receptors that have evolved rapidly by both gene duplication and recombination events. These findings were unexpected for a family of genes involved primarily in the innate immune response. H...
متن کاملHLA-KIR Interactions and Immunity to Viral Infections
Host genetic factors play a central role in determining the clinical phenotype of human diseases. Association between two polymorphic loci in human genome, human leukocyte antigen (HLA) and killer cell immunoglobulin-like receptors (KIRs), and genetically complex infectious disease, particularly those of viral etiology, have been historically elusive. Hence, defining the influence of genetic di...
متن کاملKIR/HLA Interactions and Pathogen Immunity
The innate immune system is the first line of defence in response to pathogen infection. Natural killer (NK) cells perform a vital role in this response with the ability to directly kill infected cells, produce cytokines, and cross-talk with the adaptive immune system. These effector functions are dependent on activation of NK cells which is determined by surface receptor interactions with liga...
متن کاملKIR and HLA haplotype analysis in a family lacking the KIR 2DL1-2DP1 genes.
The killer cell immunoglobulin-like receptor (KIR) gene cluster exhibits extensive allelic and haplotypic diversity that is observed as presence/absence of genes, resulting in expansion and contraction of KIR haplotypes and by allelic variation of individual KIR genes. We report a case of KIR pseudogene 2DP1 and 2DL1 gene absence in members of one family with the children suffering from acute m...
