Evidence for impaired T cell DNA methylation in systemic lupus erythematosus and rheumatoid arthritis.

چکیده
Procainamide and hydralazine inhibit T cell DNA methylation and induce autoreactivity in cloned CD4+ T cells. These drugs also induce an autoimmune syndrome, suggesting a possible relationship between DNA hypomethylation, T cell autoreactivity, and certain autoimmune diseases. To test this relationship, DNA methylation was studied in T cells from patients with rheumatoid arthritis and patients with systemic lupus erythematosus, and was found to be impaired. These results support a relationship between DNA hypomethylation and some forms of autoimmune disease.

Effects of Major Epigenetic Factors on Systemic Lupus Erythematosus
The pathogenesis of systemic lupus erythematosus (SLE) is influenced by both genetic factors and epigenetic modifications; the latter is a result of exposure to various environmental factors. Epigenetic modifications affect gene expression and alter cellular functions without modifying the genomic sequences. CpG-DNA methylation, histone modifications, and miRNAs are the main epigenetic factors ...
متن کاملAnticardiolipin Antibodies in Juvenile Rheumatoid Arthritis and Systemic Lupus Erythematosus
Background: Antiphospholipid antibody syndrome (APS) can either occur as a primary syndrome or associated with other autoimmune diseases such as systemic lupus erythematosus (SLE). Anticardiolipin antibody (aCL) of IgG and/or IgM isotype in blood, measured by a standardized ELISA is the most acceptable laboratory criteria. APS IgG isotype, particularly IgG2 subclass is more strongly associated ...

Evidence for retroviral infection in general and human immunodeficiency virus (HIV) infection in particular was sought in freshly isolated peripheral blood T cells, B cells, and monocyte-macrophages from patients with rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) and also in T cell and B cell lines established from the same source. Similar cells isolated from rheumatoid synov...
متن کاملDNA methylation governs the dynamic regulation of inflammation by apoptotic cells during efferocytosis
Efficient clearance of apoptotic cells (AC) is pivotal in preventing autoimmunity and is a potent immunosuppressive stimulus. However, activation of cells prior to apoptosis abolishes their immunoregulatory properties. Here we show using the antigen-induced model of arthritis that the degree of DNA methylation within AC confers their immunomodulatory plasticity. DNA isolated from resting and ac...
