Molecular 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
EditoriAL EditoriAL Over the course of evolution, microorganisms have developed innovative survival strategies to thrive in their hosts. 1 The human body is home to many species of bacteria, viruses, fungi, and other invertebrate parasites. Some of these organisms that live and thrive in humans are com-mensals and are harmless. They may be also beneficial to the host as they provide certain nut...
متن کاملHIV and Molecular Mimicry
For more than three decades, molecular mimicry has been considered a contributing factor in viral pathogenesis. The phenomenon comes about when viral antigens share epitopes with host cell proteins. Because tolerance is thought never to be complete, the mimicking microbe can induce anti-self antibodies, a state of autoimmunity, with resulting immunopathogenesis. This mode of attack seems preemi...
متن کاملMolecular Mimicry and T Cell–mediated Autoimmune Disease
B oth T cell tolerance and productive T cell responses require the interaction of the TCR with specific MHC–peptide ligands, triggering a cascade of signals that ultimately can lead to either proliferation or cell death (1– 3). These two opposing processes, which can occur during both peripheral T cell activation and/or positive/negative selection of T cells in the thymus, seem to be tuned by t...
متن کاملMolecular mimicry, inflammatory bowel disease, and the vaccine safety debate
Preventive immunization has provided one of the major advances in population health during the past century. However, a surprising cultural phenomenon is the emergence of concerns about immunization safety, in part due to prominently controversial biomedical studies. One ongoing theoretical safety concern is the possibility of human molecular mimicry by measles, mumps, rubella (MMR) antigens. T...
