Novel Association of Killer Cell Immunoglobulin-like Receptor Genes with EBV-infectious Diseases in Children

Killer cell immunoglobulin-like receptors （KIRs） which are mainly expressed on natural killer （NK） cells are implicated in many virus infections. However, it is unclear whether or not KIRs are associated with susceptibility to Epstein-Barr virus （EBV） infection related diseases. Therefore, the purpose of our study was to investigate possible correlation between polymorphisms of KIR genes and infectious mononucleosis （IM）/EBV-associated hemophagocytic Iymphohistiocytosis （EBV-HLH）. The polymorphisms of KIR genes were detected by polymerase chain reaction with sequence-specific primers （PCR-SSP）. The results would contribute to clarify the association of KIRs with EBV induced diseases, and provide new insights into the role of NK cells and innate immune response against viral infections and/or subsequent progression.

Interleukin-35: A key player managing pre-diabetes and chronic inflammatory type 1 autoimmune diabetes

Interleukin-35(IL-35)is a novel protein comprising IL-12αand IL-27βchains.The IL12A and EBI3 genes are responsible for its production.The study of IL-35 has experienced a substantial increase in interest in recent years,as demonstrated by many research papers.Recent clinical studies have shown that individuals who do not have a C-peptide have notably reduced amounts of IL-35 in their blood serum.This is accompanied by a drop in the percentage of IL-35+Treg cells,regulatory B cells,and CD8+FOXP3+cells that produce IL-35.This article em-phasizes the potential significance of IL-35 expression in governing the immune response and its involvement in chronic inflammatory autoimmune diabetes in pancreatic inflammation.It demonstrates IL-35's ability to regulate cytokine proportions,modulate B cells,and protect against autoimmune diabetes.However,further investigation is necessary to ascertain the precise mechanism of IL-35,and meticulous planning is essential for clinical studies.

An Overview of Genome-Wide Association Studies in Alzheimer＇s Disease

Genome-wide association studies（GWASs）have revealed a plethora of putative susceptibility genes for Alzheimer＇s disease（AD）. With the sole exception of the APOE gene, these AD susceptibility genes have not been unequivocally validated in independent studies. No single novel functional risk genetic variant has been identified. In this review, we evaluate recent GWASs of AD, and discuss their significance, limitations, and challenges in the investigation of the genetic spectrum of AD.

Application of systems biology to the study of chronic kidney disease

Chronic kidney disease （CKD） is a major public health problem that affects about 10% of the general population. Current approaches to characterize the category and progression of CKD are normally based on renal histopathological results and clinical parameters. However, this information is not sufficient to predict CKD progression risk reliably or to guide preventive interventions. Nowadays, the appearance of systems biology has brought forward the concepts of ＂-omics＂ technologies, including genomics, transcriptomics, proteomics, and metabolomics. Systems biology, together with molecular analysis approaches such as microarray analysis, genome-wide association studies （GWAS）, and serial analysis of gene expression （SAGE）, has provided the framework for a comprehensive analysis of renal disease and serves as a starting point for generating novel molecular diagnostic tools for use in nephrology. In particular, analysis of urinary mRNA and protein levels is rapidly evolving as a non-invasive approach for CKD monitoring. All these systems biological molecular approaches are required for application of the concept of ＂personalized medicine＂ to progressive CKD, which will result in tailoring therapy for each patient, in contrast to the ＂one-size-fits-all＂ therapies currently in use.
