The expression and action of Fas/Fas ligand (FasL) in multiple sclerosis has been postulated as a major pathway leading to inflammatory demyelination. To formally test this hypothesis, C57BL/6-lpr and -gld mice, which due to gene mutation express Fas and FasL in an inactive form, were immunized with myelin oligodendrocyte glycoprotein peptide(35-55). Whereas in wild-type C57BL/6 mice, experimental autoimmune encephalomyelitis (EAE), was chronic/relapsing, EAE in lpr and gld mice was characterized by a lower incidence of disease and a monophasic course. This contrasts with C57BL/6 perforin knockout mice, which showed the most severe form of EAE of all mouse strains tested, the course being chronic relapsing. The difference noted cannot be attributed to an involvement of FasL in oligodendrocyte damage since oligodendrocytes are insensitive to FasL-mediated cytotoxicity in vitro, and since in the acute phase of EAE gld mice also show CD4+ T cell infiltrates with associated demyelination in brain and spinal cord. Unlike oligodendrocytes, astrocytes were killed by FasL in vitro. It remains to be established whether this latter finding explains the different disease course of lpr and gld mice compared to wild-type and perforin knockout mice.

D009836 Oligodendroglia A class of large neuroglial (macroglial) cells in the central nervous system. Oligodendroglia may be called interfascicular, perivascular, or perineuronal (not the same as SATELLITE CELLS, PERINEURONAL of GANGLIA) according to their location. They form the insulating MYELIN SHEATH of axons in the central nervous system.

D002908 Chronic Disease Diseases which have one or more of the following characteristics: they are permanent, leave residual disability, are caused by nonreversible pathological alteration, require special training of the patient for rehabilitation, or may be expected to require a long period of supervision, observation, or care (Dictionary of Health Services Management, 2d ed). For epidemiological studies chronic disease often includes HEART DISEASES; STROKE; CANCER; and diabetes (DIABETES MELLITUS, TYPE 2).

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.

D052899 Pore Forming Cytotoxic Proteins Proteins secreted from an organism which form membrane-spanning pores in target cells to destroy them. This is in contrast to PORINS and MEMBRANE TRANSPORT PROTEINS that function within the synthesizing organism and COMPLEMENT immune proteins. These pore forming cytotoxic proteins are a form of primitive cellular defense which are also found in human LYMPHOCYTES.
D053222 Fas Ligand Protein A transmembrane protein belonging to the tumor necrosis factor superfamily that was originally discovered on cells of the lymphoid-myeloid lineage, including activated T-LYMPHOCYTES and NATURAL KILLER CELLS. It plays an important role in immune homeostasis and cell-mediated toxicity by binding to the FAS RECEPTOR and triggering APOPTOSIS.
