Experimental allergic encephalomyelitis (EAE) is a T(h)1-type cell-mediated autoimmune disease induced by immunization with myelin proteins and mediated by CD4(+) T cells. Although susceptibility to EAE is dependent largely on MHC background, the B10.S strain is resistant to induction of EAE despite sharing the I-A(s) MHC locus with the susceptible SJL strain. Furthermore, NOD mice which spontaneously develop diabetes are susceptible to EAE induction with myelin oligodendrocyte glycoprotein (MOG) 35-55, whereas a MHC congenic strain, III, which also expresses I-A(g7) MHC haplotype does not develop diabetes and is also resistant to EAE induction. We induced EAE in these four strains of mice with MOG peptides 92-106 (for I-A(s) strains) and 35-55 (for I-A(g7) strains) in complete Freund's adjuvant. In the susceptible strains (SJL and NOD) in vitro, there are high levels of IFN-gamma production, whereas the resistant strains (B10.S or III) secreted primarily IL-4/IL-10 and transforming growth factor (TGF)-beta, and had decreased levels of IFN-gamma. When brains from susceptible and resistant mice were examined by immunohistochemical methods for cytokine expression, the brains from resistant mice showed fewer infiltrates which predominantly expressed IL-4 and IL-10 and/or TGF-beta. Brains from NOD and SJL with EAE showed mainly IL-2 and IFN-gamma positive cells. Thus, resistance to MOG induced EAE in B10.S and III mouse strains is related to non-MHC genes and is associated with an altered balance of pro- and anti-inflammatory cytokines both in lymphoid tissue and in the brain following immunization with myelin antigens.

UI MeSH Term Description Entries
D007371 Interferon-gamma The major interferon produced by mitogenically or antigenically stimulated LYMPHOCYTES. It is structurally different from TYPE I INTERFERON and its major activity is immunoregulation. It has been implicated in the expression of CLASS II HISTOCOMPATIBILITY ANTIGENS in cells that do not normally produce them, leading to AUTOIMMUNE DISEASES.

D007962 Leukocytes White blood cells. These include granular leukocytes (BASOPHILS; EOSINOPHILS; and NEUTROPHILS) as well as non-granular leukocytes (LYMPHOCYTES and MONOCYTES).

D008233 Lymphotoxin-alpha A tumor necrosis factor family member that is released by activated LYMPHOCYTES. Soluble lymphotoxin is specific for TUMOR NECROSIS FACTOR RECEPTOR TYPE I; TUMOR NECROSIS FACTOR RECEPTOR TYPE II; and TUMOR NECROSIS FACTOR RECEPTOR SUPERFAMILY, MEMBER 14. Lymphotoxin-alpha can form a membrane-bound heterodimer with LYMPHOTOXIN-BETA that has specificity for the LYMPHOTOXIN BETA RECEPTOR.

D004681 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.
