Possible Relationship between the HLA-DRA1 Intron Haplotype of Three Single-Nucleotide Polymorphisms in Intron 1 of the HLA-DRA1 Gene and Autoantibodies in Children at Increased Genetic Risk for Autoimmune Type 1 Diabetes.

Immunohorizons 2022 Aug 18;6(8):614-629. Epub 2022 Aug 18.

Department of Clinical Sciences, Lund University/Clinical Research Centre, Skåne University Hospital, Malmö, Sweden; and.

Recently, a haplotype of three single-nucleotide polymorphisms (tri-SNP) in intron 1 of the HLA-DRA1 gene was found to be strongly associated with type 1 diabetes risk in HLA-DR3/3 individuals. The tri-SNP reportedly function as "expression quantitative trait loci," modulating HLA-DR and -DQ expression. The aim was to investigate HLA-DRA1 tri-SNPs in relation to extended HLA class II haplotypes and human peripheral blood cell HLA-DQ cell-surface median fluorescence intensity (MFI), the first-appearing islet autoantibody, and autoimmunity burden.

Department of Food Science, University of Tennessee, 102 Food Safety and Processing Building 2600 River Dr., Knoxville, TN, 37996, USA.

Globally, heavy metal (HM) contamination is one of the primary causes of environmental pollution leading to decreased quality of life for those affected. In particular, HM contamination in groundwater poses a serious risk to human health and the potential for destabilization of aquatic ecosystems. At present, strategies to remove HM contamination from wastewater are inefficient, costly, laborious, and often the removal poses as much risk to the environment as the initial contamination.

Genetic basis of defects in immune tolerance underlying the development of autoimmunity.

Front Immunol 2022 1;13:972121. Epub 2022 Aug 1.

Center for Translational Immunology, Benaroya Research Institute at Virginia Mason, Seattle, WA, United States.

Genetic variants associated with susceptibility to autoimmune disease have provided important insight into the mechanisms responsible for the loss of immune tolerance and the subsequent development of autoantibodies, tissue damage, and onset of clinical disease. Here, we review how genetic variants shared across multiple autoimmune diseases have contributed to our understanding of global tolerance failure, focusing on variants in the human leukocyte antigen region, PTPN2 and PTPN22, and their role in antigen presentation and T and B cell homeostasis. Variants unique to a specific autoimmune disease such as those in PADI2 and PADI4 that are associated with rheumatoid arthritis are also discussed, addressing their role in disease-specific immunopathology.

Genetic association of apolipoprotein E genotype with EEG alpha rhythm slowing and functional brain network alterations during normal aging.

Front Neurosci 2022 1;16:931173. Epub 2022 Aug 1.

Center for Genetics and Life Science, Sirius University of Science and Technology, Sochi, Russia.

The ε4 allele of the apolipoprotein E (4+) genotype is a major genetic risk factor for Alzheimer's disease (AD), but the mechanisms underlying its influence remain incompletely understood. The study aimed to investigate the possible effect of the genotype on spontaneous electroencephalogram (EEG) alpha characteristics, resting-state functional MRI (fMRI) connectivity (rsFC) in large brain networks and the interrelation of alpha rhythm and rsFC characteristics in non-demented adults during aging. We examined the EEG alpha subband's relative power, individual alpha peak frequency (IAPF), and fMRI rsFC in non-demented volunteers (age range 26-79 years) stratified by the genotype. Read More

Inflammation, microbiome and colorectal cancer disparity in African-Americans: Are there bugs in the genetics?

World J Gastroenterol 2022 Jul;28(25):2782-2801

Department of Oncology, Johns Hopkins University, Baltimore, MD 21231, United States.

Dysregulated interactions between host inflammation and gut microbiota over the course of life increase the risk of colorectal cancer (CRC). While environmental factors and socio-economic realities of race remain predominant contributors to CRC disparities in African-Americans (AAs), this review focuses on the biological mediators of CRC disparity, namely the under-appreciated influence of inherited ancestral genetic regulation on mucosal innate immunity and its interaction with the microbiome. There remains a poor understanding of mechanisms linking immune-related genetic polymorphisms and microbiome diversity that could influence chronic inflammation and exacerbate CRC disparities in AAs.
