Autoimmune uveitis induced by molecular mimicry of peptides from rotavirus, bovine casein and retinal S-antigen.
Antigenic mimicry of infectious agents and autoantigens is a proposed pathomechanism for autoimmune diseases. Here, we describe antigenic mimicry of a peptide from rotavirus, a nutritional protein from bovine milk (alphas2-casein) and a peptide thereof as well as a highly pathogenic peptide from retinal S-antigen (PDSAg), a major autoantigen in experimental autoimmune uveitis in Lewis rats. Imm...
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 کاملAutoimmune uveitis and antigenic mimicry of environmental antigens.
Autoimmunity directed against antigens of immune privileged sites, which are hidden from the immune system by blood-organ-barriers, is difficult to explain: it would require already activated cells to enter the tissue where the respective autoantigens are sequestered. Autoimmune uveitis, a sight-threatening inflammatory disease of the eye, is such an example. To induce disease autoreactive T ce...
متن کاملChronic anterior uveitis following bacille Calmette-Guérin vaccination: molecular mimicry in action?
A 13-year-old girl developed bilateral chronic anterior uveitis following bacille Calmette-Guérin (BCG) vaccination. HLA testing was negative for B27 but positive for DRB1 *0404, a variant of DR4 often associated with rheumatoid arthritis. The authors propose her HLA repertoire allowed for a BCG-induced abnormal autoimmune response by the mechanism of molecular mimicry.
