Autoimmunity is one of the most highly investigated areas of immunologic research. The principle of immune system discrimination between self and foreign molecules is fundamental to the survival of the species, and the failure to establish or maintain this discrimination can lead to a wide spectrum of diseases. As a consequence of intensive studies, much has been learned with regard to the normal functioning of the immune system and the editing processes by which self-tolerance is established. Moreover, many theories and experimental models have been developed to explore the mechanisms of autoimmune disease pathogenesis. This book is the first volume of the new series 'Current Directions in Autoimmunity', which aims to consolidate current knowledge of autoimmunity focusing on both basic and clinical aspects. Given that these diseases have a strong genetic basis, it seems appropriate that the first volume addresses this topic. It reviews the most recent findings on genes affecting autoimmunity and genome-wide studies defining the multiple loci predisposing to prominent autoimmune diseases, such as lupus, arthritis, diabetes and multiple sclerosis. For each of these entities, studies in experimental models as well as humans are covered. The authoritative and timely material will be of interest to investigators in the fields of immunology and genetics, to clinicians with interest in rheumatology, endocrinology and neurology, and to those working to devise gene-specific therapies for a variety of inflammatory conditions.

This title provides an extremely helpful analysis of genes that may be associated with autoimmunity, and answers questions such as how these genes can be identified, and how the functions of the gene products can be elucidated. Incorporating data on disease-associated chromosomal loci that has been accumulated from inbred mice, the title: descibes how some susceptibility loci may be common to many diseases, whereas others are relatively disease specific discusses the importance of developing criteria for establishing the significance of these different categories of disease-associated loci.

Autoimmune disorders are known to affect a substantial number of people worldwide, demonstrating a gender bias and are the second largest cause of chronic illness. Recently, the attention has been focused on lifestyle changes as a major factor in the rise of autoimmune disease frequency. The two sections of this book are focused on the new opportunities for moving research forward, leading to a new approach to prevention and treatment of autoimmune diseases. A better understanding of the mechanisms of gene expression and triggering signaling pathways, which is involved in autoimmune pathogenesis simultaneously with current data for the interaction of microbiota with human immune system, will help to better understand the immune imbalance implicated in autoimmunity.

The Epigenetics of Autoimmunity covers a topic directly related to translational epigenetics. Via epigenetic mechanisms, a number of internal and external environmental risk factors, including smoking, nutrition, viral infection and the exposure to chemicals, could exert their influence on the pathogenesis of autoimmune diseases. Such factors could impact the epigenetic mechanisms, which, in turn, build relationship with the regulation of gene expression, and eventually triggering immunologic events that result in instability of immune system. Since epigenetic aberrations are known to play a key role in a long list of human diseases, the translational significance of autoimmunity epigenetics is very high. To bridge the gap between environmental and genetic factors, over the past few years, great progress has been made in identifying detailed epigenetic mechanisms for autoimmune diseases. Furthermore, with rapid advances in technological development, high-throughput screening approaches and other novel technologies support the systematic investigations and facilitate the epigenetic identification. This book covers autoimmunity epigenetics from a disease-oriented perspective and several chapters are presented that provide advances in wide-spread disorders or diseases such as systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), multiple sclerosis (MS), type 1 diabetes (T1DM), systemic sclerosis (SSc), primary Sjögren's syndrome (pSS) and autoimmune thyroid diseases (AITDs). These emerging epigenetic studies provide new insights into autoimmune diseases, raising great expectations among researchers and clinicians. This seminal book on this topic comprehensively covers the most recent advances in this exciting and rapidly developing new science. They might reveal not only new clinical biomarkers for diagnosis and disease progression, but also novel targets for potential epigenetic therapeutic treatment. Provides the accurate and cutting-edge information on autoimmunity epigenetics Wide coverage appeals to those interested in fundamental epigenetics and inheritance to those with more clinical interests Critical reviews of the mean of deriving and analysing autoimmunity epigenetics information as well as its translational potential Up-to-date coverage of emerging topics in autoimmunity epigenetics

The main aim of this volume is to provide an updated overview of the genetic basis of a group of complex disorders that are considered rare individually, but show a relatively high prevalence on the whole in developed countries: the rare autoimmune diseases. These are chronic disorders that involve long and expensive treatments with considerable side effects that may dramatically reduce the quality of life of affected people. Therefore, shedding light into their pathologic mechanisms is a major concern given their growing social and economic awareness and impact. General sections include different chapters on single entities as systemic lupus and sclerosis, Behçet’s disease, Sjogren’s syndrome and polymiositis, and sections devoted to autoimmune vasculitis, hepatic autoimmune conditions, as well as those affecting the nervous system, and a concluding chapter in which the shared predisposition amongst all diseases is discussed. All the chapters are given a homogeneous scheme in which the authors explain the clinical singularities of every disease and report the recent breakthrough discoveries related to them, giving a critical interpretation and suggesting future perspectives. All contributors are renowned researchers with high expertise in each disease. Due to the exponential increase in our understanding of the genetic causes of these complex diseases, a major advance in biomedical discovery is taking place. However, most of the achievements in this field are very recent and there is a lack of bibliography gathering them together. This book is thus filling a gap and will prove a useful companion to clinicians in the first place (internists, rheumatologists, clinical immunologists, and hematologists) but also to basic and applied researchers.

This book will address the growing roles of epigenetics in disease pathogenesis, and review the contribution of epigenetic modifications to disease onset and progression. The roles that epigenetics plays in facilitating effects of the environment on allergy and immunologic diseases will be reviewed. The book is divided into three parts – the first is an introduction to epigenetics and the methods that have been developed to study epigenetics, the second addresses epigenetics in allergic diseases and the third part will cover epigenetics in autoimmune diseases. With the rapid expansion of knowledge of how genes are regulated and how this regulation affects disease phenotypes, this book will be attractive to experienced researchers as well as those just launching an epigenetics research program. It will also be of interest to allergist, immunologists, rheumatologists and dermatologist who are engaged in clinical practice as a resource for understanding the basis for personalized and precision medicine. For example, the role that epigenetics plays in the pathogenesis in various allergic and autoimmune disorders and how this determines disease phenotypes will be covered extensively in this book. This book will thus help fill the gap in available resources on epigenetics in allergy and autoimmune diseases.

The Molecular Aspects of Autoimmunity contains a selection of the papers presented at the first of a series of biannual meetings on molecular aspects of autoimmunity held in L'Esterel, Quebec, Canada, October 30-November 2, 1988. The book contains 20 chapters and begins with a study of the expression of the Ly-1 gene and V gene families in autoantibodies. This is followed by separate chapters on the structural characteristics of human IgM autoantibodies; human IgV gene segments for autoantibodies; and the genetic basis of anti-DNA immune responses. Subsequent chapters cover topics such as the epibodies from the immune response to the acetylcholine receptor (AChR); the specificities and idiotypes of anti-histone H1 autoantibodies; T cell tolerance; and T cell antigen receptor (TCR) gene biology and the genomic composition and expressed repertoire of these genes in several autoimmune and normal mouse strains. Also discussed are MHC Class II associations with autoimmune disorders such as type 1 diabetes, rheumatoid arthritis, and thyroid disease.

BACKGROUND: Autoimmune diseases require the involvement and activation of immune cells and occur when the body builds up an immune response against its own tissues. This process takes place due to the inability to distinguish self-antigen from foreign antigen. Systemic autoimmunity represents an important cause of morbidity and mortality in humans. The mechanisms triggering autoimmune responses are complex and involve a network of genetic factors. Genome wide association study (GWAS) is a powerful method, used to identify genetic risk factors in numerous diseases, such as systemic autoimmune diseases. The goal of GWAS is to identify these genetic risk factors in order to make predictions about who is at risk and investigate the biological process of disease susceptibility. There are several valuable mouse models to investigate the underlying mechanisms causing systemic autoimmune diseases in which mercury induced autoimmunity (HgIA) is a well- established and relevant model. HgIA in mice includes development of autoantibodies, immune complex glomerulonephritis, lymphocyte proliferation, hypergammaglobulinemia and polyclonal B cell activation. In humans, mercury exposure accumulates with considerable concentrations in kidney, liver, and brain. Toxicokinetics of Hg has been studied extensively but the key for inter-individual variation in humans are largely unclear. Differences in accumulation of renal Hg between inbred mouse strains suggest a genetic inter-strain variation regulating retention or/and excretion of Hg. OBJECTIVES: To find loci and candidate genes associated with phenotypes involved in the development of autoimmunity and find candidate genes involved in the regulation of renal Hg excretion. METHODS: MHC II (H-2s) mice were paired (A.SW x B10.S) to obtain F2 offspring exposed to 2.0 or 4.0 mg Hg in drinking water for 6 weeks. Mercury induced autoimmune phenotypes were studied with immunofluorescence (anti-nucleolar antibodies (ANoA)), ELISA anti-DNP/anti-ssDNA (polyclonal B cell activation), anti-chromatin antibodies (ACA) (4.0 mg Hg), and serum IgG1 concentrations. Mercury accumulation in kidney was performed previously and data was included as phenotype. F2 mice exposed to 2.0 mg Hg were genotyped with microsatellites for genome-wide scan with Ion Pair Reverse Phase High Performance Liquid Chromatography (IP RP HPLC). F2 mice exposed to 4.0 mg Hg were genotyped with single nucleotide polymorphisms for genomewide scan with SNP&SEQ technology platform. Quantitative trait loci (QTL) was established with R/QTL. Denaturing HPLC, next generation sequencing, conserved region analysis and genetic mouse strain comparison were used for haplotyping and fine mapping on QTLs associated with Hg concentration in kidney, development of ANoA and serum IgG1 hypergammaglobulinemia. Candidate genes (Pprc1, Bank1 and Nfkb1) verified by additional QTL were further investigated by real time polymerase chain reaction. Genes involved in the intracellular signaling together with candidate genes were included for gene expression analysis. RESULTS: F2 mice exposed to 2.0 mg Hg had low or no development of autoantibodies and showed no significant difference in polyclonal B cell activation in the B10.S and F2 strains. F2 mice exposed to 4.0 mg Hg developed autoantibodies and significantly increased IgG1 concentration and polyclonal B cell activation (anti-DNP). QTL analysis showed a logarithm of odds ratio (LOD) score between 2.9 – 4.36 on all serological phenotypes exposed to 4.0 mg Hg, and a LOD score of 5.78 on renal Hg concentration. Haplotyping and fine mapping associated the development of ANoA with Bank1 (B-cell scaffold protein with ankyrin repeats 1) and Nfkb1 (nuclear factor kappa B subunit 1). The serum IgG1 concentration was associated with a locus on chromosome 3, in which Rxfp4 (Relaxin Family Peptide/INSL5 Receptor 4) is a potential candidate gene. The renal Hg concentration was associated with Pprc1 (Peroxisome Proliferator-Activated Receptor Gamma, Co-activator-Related). Gene expression analysis revealed that the more susceptible A.SW strain expresses significantly higher levels of Nfkb1, Il6 and Tnf than the less susceptible B10.S strain. The A.SW strain expresses significantly lower levels of Pprc1 and cascade proteins than the B10.S strain. Development of ACA was associated with chromosomes 3, 6, 7 and 16 (LOD 3.1, 3.2, 3.4 and 6.8 respectively). Polyclonal B cell activation was associated with chromosome 2 with a LOD score of 2.9. CONCLUSIONS: By implementing a GWAS on HgIA in mice, several QTLs were discovered to be associated with the development of autoantibodies, polyclonal B cell activation and hypergammaglobulinemia. This thesis plausibly supports Bank1 and Nfkb1 as key regulators for ANoA development and HgIA seems to be initiated by B cells rather than T cells. GWAS on renal mercury excretion plausibly supports Pprc1 as key regulator and it seems that this gene has a protective role against Hg.
