Multiple sclerosis (MS) is a chronic and debilitating autoimmune disorder of the central nervous system in which the autoimmune T cells destroy myelin, thus causing lesion, damage, and neuronal dysfunction. Experimental autoimmune encephalomyelitis (EAE) is an animal model of MS that is particularly useful for testing new therapeutic approaches against MS. Aspirin (acetyl salicylic acid) is one of the oldest and widely used medicines in the world, and recently it has been shown that low-dose aspirin is capable of suppressing the disease process of EAE in mice. One of the root causes of this autoimmune disease process is the decrease and/or suppression of Foxp3-expressing anti-autoimmune regulatory T cells (Tregs) and associated increase in autoimmune T-helper 1 (Th1) and Th17 cells. Aspirin upregulates Tregs and decreases Th1 and Th17 responses. Accordingly, the suppression of Tregs abrogates the protective effect of aspirin on EAE, indicating that aspirin protects EAE via Tregs. While there are several mechanisms for the maintenance of Tregs under immune insults, aspirin increases the level of interleukin-11 (IL-11), an immunomodulatory cytokine, and IL-11 alone is sufficient to protect Tregs. Being a multifunctional molecule, aspirin stimulates the activation of cAMP-response element-binding (CREB) to promote the recruitment of CREB to the gene promoter and stimulate the transcription of in splenocytes. Therefore, it appears that low-dose aspirin protects EAE via CREB-mediated stimulation of IL-11-Treg pathway and that aspirin may have therapeutic importance in MS.

Experimental animal models for human AUTOIMMUNE DISEASES OF THE NERVOUS SYSTEM. They include GUILLAIN-BARRE SYNDROME (see NEURITIS, AUTOIMMUNE, EXPERIMENTAL); MYASTHENIA GRAVIS (see MYASTHENIA GRAVIS, AUTOIMMUNE, EXPERIMENTAL); and MULTIPLE SCLEROSIS (see ENCEPHALOMYELITIS, AUTOIMMUNE, EXPERIMENTAL).
An experimental animal model for central nervous system demyelinating disease. Inoculation with a white matter emulsion combined with FREUND'S ADJUVANT, myelin basic protein, or purified central myelin triggers a T cell-mediated immune response directed towards central myelin. The pathologic features are similar to MULTIPLE SCLEROSIS, including perivascular and periventricular foci of inflammation and demyelination. Subpial demyelination underlying meningeal infiltrations also occurs, which is also a feature of ENCEPHALOMYELITIS, ACUTE DISSEMINATED. Passive immunization with T-cells from an afflicted animal to a normal animal also induces this condition. (From Immunol Res 1998;17(1-2):217-27; Raine CS, Textbook of Neuropathology, 2nd ed, p604-5)
A group of 7 proteins produced from a single gene by alternate splicing found in central and peripheral nervous system myelin. The major basic protein (MBP) has long been of interest because it is the antigen, that, when injected into an animal, elicits a cellular immune response that produces the CNS autoimmune disease called experimental allergic encephalomyelitis (ENCEPHALOMYELITIS, ALLERGIC). In the peripheral nervous system, myelin basic protein 18.5-kDa is often referred to as the P1 protein. (From Siegel et al., Basic Neurochemistry, 5th ed, p130, 133)
A non-steroidal anti-inflammatory agent that is less effective than equal doses of ASPIRIN in relieving pain and reducing fever. However, individuals who are hypersensitive to ASPIRIN may tolerate sodium salicylate. In general, this salicylate produces the same adverse reactions as ASPIRIN, but there is less occult gastrointestinal bleeding. (From AMA Drug Evaluations Annual, 1992, p120)
