Future studies on the topic will be aimed at discovering the relationship between the stage of disease and antibody levels to the bacterial mimic in individual patients, which can assist in the development of a rapid test which will aim to detect antibodies to the bacterial ubiquitin and provide insight into a persons predisposition to an autoimmune disease. HSP are known to be able to influence both innate and adaptive immune response and induce the expression of interleukins under a variety of experimental conditions. Lipoproteins from Borrelia burgdorferi applied in liposomes and presented to dendritic cells induce CD8+ T-lymphocytes in vitro.

Detection of mycoplasmal infections in blood of patients with rheumatoid arthritis. MAM is a zinc-dependent antigen that binds to MHC class II molecules. Immunol Lett 2008; 116: 86-94. Therefore, the findings suggest that an initial reaction to the unique part of theB. fragilisversion of ubiquitin can trigger the production of antibodies to the part of the molecule that is the same as the human version. Your immune system is made up of organs and cells meant to protect your body from bacteria, parasites, viruses and cancer cells. Heat shock proteins induce T cell regulation of chronic inflammation. EFFECTS Mcrobes Immune Sys 2000; 93-107. NO is also expressed by cells when exposed to IFN-?.

Is there any relationship between streptococcal infection and multiple sclerosis?. Mycoplasma arthritidis superantigen (MAM)-induced macrophage nitric oxide release is MHC class II restricted, interferon gamma dependent, and toll-like receptor 4 independent. A better understanding of how the virus infection contributes to autoimmune diseases in some people could lead to therapies that interrupt or reverse the process.

Serum reactivity against OspA is also found in RA patients18. But other illnesses can cause the same symptoms. Nonstructural protein 1 (NS1) is a glycoprotein that encodes a 352-amino-acid polypeptide and has a molecular weight of 46-55 kDa depending on its glycosylation . Some bacterial LPS (lipopolysaccharides) apparently bear molecular similarity to the human gangliosides GM1, GM1b, GD1a, and GalNAc-GD1a of the motor axolemma and are said to be the target epitopes for antibodies occurring in the GB subtype acute motor axonal neuropathy. In vitro studies have suggested that HSP70 is actively released in response to heat shock and induces the production of IL-10 in fibroblast-like synoviocytes by TLR4 signalling99.
