The aim of this study was to analyze Killer Ig-Like Receptor (KIR) gene polymorphisms in Roma people from Republic of Macedonia. The studied sample consists of 103 healthy unrelated individuals, aged 20-45 years. All individuals are of Roma origin, residents of different geographical regions (Gostivar, Skopje, and Kochani). The population genetics analysis package, Arlequin, was used for analysis of the data. We found that all 16 KIR genes were observed in the Roma individuals and framework genes (KIR3DL3, KIR3DP1, KIR- 2DL4, and KIR3DL2) were present in all individuals. The frequencies of other KIR genes were: KIR2DP1 (1), KIR2DL1 (0.961), KIR2DL2 (0.544), KIR2DL3 (0.874), KIR2DL5 (0.311), KIR3DL1 (0.990), KIR- 2DS1 (0.330), KIR2DS2 (0.553), KIR2DS3 (0.359), KIR2DS4 (0.981), KIR2DS5 (0.291), and KIR3DS1 (0.379). The results of tested linkage disequilibrium (LD) among KIR genes demonstrated that KIR genes present a wide range of linkage disequilibrium. The obtained results for KIR genes and genotype frequencies in Macedonian Roma individuals can be used for anthropological comparisons.

Introduction: Accurate genotyping of Killer cell Immunoglobulin-like Receptor (KIR) genes plays a pivotal role in enhancing our understanding of innate immune responses, disease correlations, and the advancement of personalized medicine. However, due to the high variability of the KIR region and high level of sequence similarity among different KIR genes, the generic genotyping workflows are unable to accurately infer copy numbers and complete genotypes of individual KIR genes from next-generation sequencing data. Thus, specialized genotyping tools are needed to genotype this complex region.

Background: Cytomegalovirus (CMV) is a common clinical infection especially after organ transplantation and threaten the survival of recipients. Natural killer (NK) cells play an important role in the process of CMV infection. In this study, we want to explore that if the different of killer immunoglobulin-like receptors (KIRs) of NK cells could affect CMV infection.

Flonicamid is a selective insecticide effective against piercing-sucking insects. Although its molecular target has been identified in other species, the specific effects and detailed mechanism of action in Kuwayama remain poorly understood. In this study, we determined that the LC of flonicamid for adults was 16.
