[Molecular mimicry in the etiology of autoimmune diseases].
There are currently more than 80 different autoimmune diseases, affecting approximately 100 million people worldwide. The etiology of most autoimmune diseases is unknown. The highest incidence of these diseases is in the developed countries and they are more common in women than in men. Among the most often listed factors responsible for the onset of autoimmunity are genetic predisposition and...
متن کاملMolecular mimicry in autoimmune disease.
The origins of autoimmune disease are multifactorial. Environmental factors and a genetic predisposition result in tissue injury caused by autoreactive T cells or antibodies. Usually a single organ or individual cell type is aVected in the absence of gross abnormalities of the immune system. Autoimmune diseases tend to have long, asymptomatic prodromal periods and the initiating events leading ...
متن کاملMolecular mimicry in the autoimmune pathogenesis of rheumatic heart disease.
Molecular mimicry is a hallmark of the pathogenesis of rheumatic fever where the streptococcal group A carbohydrate epitope, N-acetyl glucosamine, and the a-helical coiled-coil streptococcal M protein structurally mimic cardiac myosin in the human disease, rheumatic carditis, and in animal models immunized with streptococcal M protein and cardiac myosin. Recent studies have unraveled the potent...
متن کاملPotential Role of Bacterial Infection in Autoimmune Diseases: A New Aspect of Molecular Mimicry
Molecular mimicry is an attractive mechanism for triggering autoimmunity. In this review, we explore the potential role of evolutionary conserved bacterial proteins in the production of autoantibodies with focus on granulomatosis with polyangiitis (GPA) and rheumatoid arthritis (RA). Seven autoantigens characterized in GPA and RA were BLASTed against a bacterial protein database. Of the seven a...
متن کاملMolecular mimicry and immune-mediated diseases.
Molecular mimicry has been proposed as a pathogenetic mechanism for autoimmune disease, as well as a probe useful in uncovering its etiologic agents. The hypothesis is based in part on the abundant epidemiological, clinical, and experimental evidence of an association of infectious agents with autoimmune disease and observed cross-reactivity of immune reagents with host 'self' antigens and micr...
