Sjögren's disease (SjD) is a long-term autoimmune disease that primarily affects the body's exocrine glands, particularly the lacrimal and salivary glands. Common symptoms include dry mouth, dry eyes and often seriously affects other organ systems, such as the lungs, kidneys, and nervous system.
In immunology, autoimmunity is the system of immune responses of an organism against its own healthy cells, tissues and other normal body constituents. Any disease resulting from this type of immune response is termed an "autoimmune disease". Prominent examples include celiac disease, diabetes mellitus type 1, Henoch–Schönlein purpura, systemic lupus erythematosus, Sjögren syndrome, eosinophilic granulomatosis with polyangiitis, Hashimoto's thyroiditis, Graves' disease, idiopathic thrombocytopenic purpura, Addison's disease, rheumatoid arthritis, ankylosing spondylitis, polymyositis, dermatomyositis, and multiple sclerosis. Autoimmune diseases are very often treated with steroids.
Antinuclear antibodies are autoantibodies that bind to contents of the cell nucleus. In normal individuals, the immune system produces antibodies to foreign proteins (antigens) but not to human proteins (autoantigens). In some cases, antibodies to human antigens are produced; these are known as autoantibodies.
Rheumatoid factor (RF) is the autoantibody that was first found in rheumatoid arthritis. It is defined as an antibody against the Fc portion of IgG and different RFs can recognize different parts of the IgG-Fc. RF and IgG join to form immune complexes that contribute to the disease process such as chronic inflammation and joint destruction at the synovium and cartilage.
FOXP3, also known as scurfin, is a protein involved in immune system responses. A member of the FOX protein family, FOXP3 appears to function as a master regulator of the regulatory pathway in the development and function of regulatory T cells. Regulatory T cells generally turn the immune response down. In cancer, an excess of regulatory T cell activity can prevent the immune system from destroying cancer cells. In autoimmune disease, a deficiency of regulatory T cell activity can allow other autoimmune cells to attack the body's own tissues.
Connective tissue disease, also known as connective tissue disorder, or collagen vascular diseases, refers to any disorder that affect the connective tissue. The body's structures are held together by connective tissues, consisting of two distinct proteins: elastin and collagen. Tendons, ligaments, skin, cartilage, bone, and blood vessels are all made of collagen. Skin and ligaments contain elastin. The proteins and the body's surrounding tissues may suffer damage when these connective tissues become inflamed.
Yehuda Shoenfeld is an Israeli physician and autoimmunity researcher.
In immunology, an adjuvant is a substance that increases or modulates the immune response to a vaccine. The word "adjuvant" comes from the Latin word adiuvare, meaning to help or aid. "An immunologic adjuvant is defined as any substance that acts to accelerate, prolong, or enhance antigen-specific immune responses when used in combination with specific vaccine antigens."
HLA-DR17 (DR17) is an HLA-DR serotype that recognizes the DRB1*0301 and *0304 gene products. DR17 is found at high frequency in Western Europe. DR17 is part of the broader antigen group HLA-DR3 and is very similar to the group HLA-DR18.
Deoxyribonuclease gamma is an enzyme that in humans is encoded by the DNASE1L3 gene. This gene's is located on chromosome 3's "p arm", i.e., short arm, between region 1, band 4, sub-band 3 and region 2, band 1, sub-band 1
Protective autoimmunity is a condition in which cells of the adaptive immune system contribute to maintenance of the functional integrity of a tissue, or facilitate its repair following an insult. The term ‘protective autoimmunity’ was coined by Prof. Michal Schwartz of the Weizmann Institute of Science (Israel), whose pioneering studies were the first to demonstrate that autoimmune T lymphocytes can have a beneficial role in repair, following an injury to the central nervous system (CNS). Most of the studies on the phenomenon of protective autoimmunity were conducted in experimental settings of various CNS pathologies and thus reside within the scientific discipline of neuroimmunology.
An autoimmune disease is a condition that results from an anomalous response of the adaptive immune system, wherein it mistakenly targets and attacks healthy, functioning parts of the body as if they were foreign organisms. It is estimated that there are more than 80 recognized autoimmune diseases, with recent scientific evidence suggesting the existence of potentially more than 100 distinct conditions. Nearly any body part can be involved.
Autoimmune polyendocrine syndrome type 1 (APS-1), is a subtype of autoimmune polyendocrine syndrome. It causes the dysfunction of multiple endocrine glands due to autoimmunity. It is a genetic disorder, inherited in autosomal recessive fashion due to a defect in the AIRE gene , which is located on chromosome 21 and normally confers immune tolerance.
Anti-SSA autoantibodies are a type of anti-nuclear autoantibodies that are associated with many autoimmune diseases, such as systemic lupus erythematosus (SLE), SS/SLE overlap syndrome, subacute cutaneous lupus erythematosus (SCLE), neonatal lupus and primary biliary cirrhosis. They are often present in Sjögren's syndrome (SS). Additionally, Anti-Ro/SSA can be found in other autoimmune diseases such as systemic sclerosis (SSc), polymyositis/dermatomyositis (PM/DM), rheumatoid arthritis (RA), and mixed connective tissue disease (MCTD), and are also associated with heart arrhythmia.
Neuropsychiatric systemic lupus erythematosus or NPSLE refers to the neurological and psychiatric manifestations of systemic lupus erythematosus. SLE is a disease in which the immune system attacks the body's own cells and tissues. It can affect various organs or systems of the body. It is estimated that over half of people with SLE have neuropsychiatric involvement.
Autoimmunity refers to a pathological immune response of the body's immune system against itself. Autoimmune disease is widely recognized to be significantly more common in women than in men, and often presents differently between the sexes. The reasons for these disparities are still under investigation, but may in part involve the presence of an additional X chromosome in women, as well as the higher presence of female sex hormones such as estrogen. The risk, incidence, and character of autoimmune disease in women may also be associated with female-specific physiological changes, such as hormonal shifts during menses, pregnancy, and menopause.
The Children's Medical Safety Research Institute (CMSRI) was a United States based anti-vaccination group which funded a number of pseudoscientific studies, notably by Christopher Shaw of the University of British Columbia, and his collaborator Lucija Tomljenovic, and by Christopher Exley of Keele University, which purport to link aluminium in vaccines to autism. The studies have been rejected by the World Health Organization and some have been retracted. A claimed "vaccinated vs. unvaccinated" cohort study has also been debunked.
Interleukin 40 (IL-40), also known with other name C17orf99, is a protein belonging to a group of cytokines called interleukins. It is encoded by a gene that does not belong to any cytokine superfamily. This cytokine is produced primarily by human expression tissues such as bone marrow and fetal liver, and its expression can be also induced in peripheral B cells after activation. IL-40 is involved in immunoglobulin A (IgA) production, and plays an important role in humoral immune responses and B cell homeostasis and development.
