The majority of anti-nuclear antibodies do not have a proven pathogenic role in systemic lupus erythematosus (SLE). The pathogenicity of native anti-DNA antibodies, suggested by clinical data, is difficult to confirm. It is linked to several factors: isotype and avidity of these antibodies, affinity for DNA, size of immune complexes. DNA, anti-DNA antibodies and cross-reactive anti-DNA idiotypes (16/6) have been isolated from human and NZB mouse glomeruli. Moreover, DNA has a particular affinity for the glomerular membrane due to its cross-reactivity with some constituents of this membrane. Anti-SSA (Ro) antibodies may play a role in some cases of nephropathy in SLE and participate in photosensitization. They are associated with neonatal lupus, with some cases of fetal death in black women and with the atrioventricular heart block. However, factors other than these antibodies are needed to induce such lesions. Anti-U1 RNP antibodies do not protect against kidney involvement in SLE; however, they can decrease suppressive function by penetrating into suppressor T cells. Anti-Sm antibodies may have particular immunoregulation properties. Some antinuclear antibodies may at least in part, be responsible for the lesions in SLE, in conjunction with other still-unknown factors.

UI	MeSH Term	Description	Entries
D008180	Lupus Erythematosus, Systemic	A chronic, relapsing, inflammatory, and often febrile multisystemic disorder of connective tissue, characterized principally by involvement of the skin, joints, kidneys, and serosal membranes. It is of unknown etiology, but is thought to represent a failure of the regulatory mechanisms of the autoimmune system. The disease is marked by a wide range of system dysfunctions, an elevated erythrocyte sedimentation rate, and the formation of LE cells in the blood or bone marrow.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D000941	Antigens	Substances that are recognized by the immune system and induce an immune reaction.	Antigen
D000974	Antibodies, Antinuclear	Autoantibodies directed against various nuclear antigens including DNA, RNA, histones, acidic nuclear proteins, or complexes of these molecular elements. Antinuclear antibodies are found in systemic autoimmune diseases including systemic lupus erythematosus, Sjogren's syndrome, scleroderma, polymyositis, and mixed connective tissue disease.
