Ademowo, Lisa Staunton, Oliver FitzGerald and Stephen R. Pennington ContentsVI Preface Recently, it has been a great challenge to acquire an in-depth knowledge in regards to the inner workings and interactions between the immune system and environmental factors along with their impact on human health. Environmental factors like growing pollution, changes in lifestyle habits, dietary compo‐ nents, as well as various microorganisms are interfering with components of our immune system driving a normal immune response to hyper- or hypo-reactivity. When the immune system becomes hyper-reactive it targets one’s own healthy cells leading to the destruction of tissues in the body, a process which is known as the onset of autoim‐ mune disease. The common target organs include the thyroid, adrenal, stomach, liver, pan‐ creas, kidneys, skin, joints, muscles and the nervous system. The organ specific autoantibodies often occur together with non-organ specific antibodies such as anti-DNA and anti-nucleoproteins in Systemic Lupus Erythematosus (SLE). Autoimmune disorders are known to affect a substantial number of people worldwide, demonstrating a gender bias and it is the second largest cause of chronic illness. They repre‐ sent the fifth leading cause of death among women in age groups up to 60. The main feature of the human immune system is the fine discrimination between self com‐ ponents from foreign antigens. Immunological tolerance is a state of unresponsiveness in‐ duced by prior exposure to a particular antigen, mostly self antigens. Thus, the body must establish self-tolerance mechanisms in order to avoid reactivity towards self components. One theory explains that breaking of self-tolerance is when some microorganisms (such as bacteria or viruses) or xenobiotics trigger the changes in immune regulation which results in autoimmune disorders. Recognition of the molecular pattern of a pathogen, which is distin‐ guishable from the host molecules is important for protective immune response and when mistaken, could often lead to autoimmunity. This process strongly depends on the individu‐ al genetics background in a person. Certain individuals are genetically susceptible to devel‐ oping autoimmune diseases. There are a number of genes that may plausibly be involved in the development of autoimmunity. It is known that genetics predisposition is associated with three main sets of genes, including immunoglobulins, T-cell receptors and major histo‐ compatibility complex (MHC), but are not restricted to them. The development of autoim‐ munity is also strongly influenced by inherited disease-associated single nucleotide polymorphisms rather than deletion or rearrangements. Cytokine, cytokine receptors and TLR-associated genes have recently attracted great interest as candidate genes for autoim‐ mune diseases. Over the past decade there has been great interest in testing candidate gene polymorphisms for evidence of their association with various autoimmune diseases. The ge‐ netic hallmarks of autoimmunity are undoubted, however particular genes and triggering intracellular signaling pathway remains elusive. Genes of cytokine and immune cell recep‐ tors regulating function of immune system are expressed under control of intracellular sig‐ naling pathway such as TLR signaling pathway, Fc receptors, receptors and ligands of immunological synapses, vitamin D receptors and other immune related genes. Two opposite hypothesis are currently under investigation. One of them (hygiene hypothe‐ sis) discusses whether the reduced exposure to certain infections, as a result of improved hygiene and living conditions, may be responsible for the increased incidence in autoim‐ mune conditions. The other hypothesis is that autoimmune diseases might be a conse‐ quence of post-infections conditions. Despite this contradiction, infection agents and their antigens obviously play a pivotal role in the development of autoimmunity through inter‐ action with the immune system. Arguments that support the role of infection in specific autoimmune diseases come from clinical, epidemiological and laboratory studies. New da‐ ta demonstrates that the gut flora compositions can also influence the development of au‐ toimmune diseases. For example, the use of probiotics containing lactobacilli decreases the incidence of diabetes in NOD mice. At the same time, a range of differing factors such as dietary supplements, hormones, alcohol consumption, vitamins and drugs, cigarette smok‐ ing, etc. implicated in autoimmune disease onset. Dietary antigens also stimulate antigen receptors and aberrant immune response can progress to autoimmunity. According to the afore discussed, it seems obvious that neither genetic predisposition nor environmental factors alone are sufficient to cause the disease. The triggering factors and intracellular signaling pathway crosstalk are currently under extensive investigation with high hopes for revealing the autoimmunity clue. In conclusion, autoimmune diseases develop in genetically predisposed organisms as a re‐ sult of a specific triggering agent (infectious or noninfectious), causing dysfunction in the immune system activity with subsequently developed abnormal autoimmune mechanism affecting its own cells and tissues of the organism. This book attempts to seize the new opportunities for moving research forward, leading to a new approach for the prevention and treatment of autoimmune diseases. The first section of this book is focused on genes, gene expression and signaling pathways involved in autoim‐ mune pathogenesis. The second one attempts to present current data for interaction of mi‐ crobiota with human immune system, which are implicated in the development of autoimmune disease. We hope the book will be useful for anyone wanting to expand their knowledge of the oc‐ currence and mechanisms of autoimmunity.
