The relative contribution of virus vis-a\u0300-vis the immune system in the pathogenesis of DA-induced white matter disease remains unclear, as is also true in MS. To clarify the pathogenesis of DA-induced demyelination, we used Cre\/<jats:italic>lox<\/jats:italic>P technology to generate a transgenic mouse that has tamoxifen (Tm)-inducible expression of a subgenomic segment of DA RNA in oligodendrocytes and Schwann cells. Tm-treated young transgenic mice developed progressive weakness leading to death, with abnormalities of oligodendrocytes and Schwann cells and demyelination, but without inflammation, demonstrating that DA virus can play a direct pathogenic role in demyelination. Tm treatment of mice at a later age resulted in milder disease, with evidence of peripheral nerve remyelination and focal fur depigmentation; surviving weak mice had persistent expression of the recombined transgene in the CNS, suggesting that the DA subgenomic segment can cause cellular dysfunction but not death, possibly similar to the situation seen during DA virus persistence. These studies demonstrate that DA RNA or a DA protein(s) is toxic to myelin-synthesizing cells. This Cre\/<jats:italic>lox<\/jats:italic>P transgenic system allows for spatially and temporally controlled expression of the viral transgene and is valuable for clarifying nonimmune (and immune) mechanisms of demyelination induced by TMEV as well as other viruses.<\/jats:p>","DOI":"10.1128\/jvi.02432-07","type":"journal-article","created":{"date-parts":[[2008,4,10]],"date-time":"2008-04-10T00:54:00Z","timestamp":1207788840000},"page":"5879-5886","update-policy":"http:\/\/dx.doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":6,"title":["A Subgenomic Segment of Theiler's Murine Encephalomyelitis Virus RNA Causes Demyelination"],"prefix":"10.1128","volume":"82","author":[{"given":"Gleb","family":"Baida","sequence":"first","affiliation":[{"name":"Department of Neurology"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brian","family":"Popko","sequence":"additional","affiliation":[{"name":"Department of Neurology"},{"name":"The Jack Miller Center for Peripheral Neuropathy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert L.","family":"Wollmann","sequence":"additional","affiliation":[{"name":"Department of Pathology"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Spyridon","family":"Stavrou","sequence":"additional","affiliation":[{"name":"Committee of Microbiology, University of Chicago Pritzker School of Medicine, Chicago, Illinois 60637"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wensheng","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Neurology"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria","family":"Tretiakova","sequence":"additional","affiliation":[{"name":"Department of Pathology"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas N.","family":"Krausz","sequence":"additional","affiliation":[{"name":"Department of Pathology"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Raymond P.","family":"Roos","sequence":"additional","affiliation":[{"name":"Department of Neurology"},{"name":"The Jack Miller Center for Peripheral Neuropathy"},{"name":"Committee of Microbiology, University of Chicago Pritzker School of Medicine, Chicago, Illinois 60637"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"235","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1038\/nm0995-927"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1002\/gene.10154"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.virol.2006.09.009"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0092-8674(01)00372-5"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1097-2765(00)80464-5"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1128\/JVI.78.20.11097-11107.2004"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.virusres.2004.07.009"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.91.5.1796"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1128\/jvi.65.6.3395-3399.1991"},{"key":"e_1_3_2_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1044-7431(03)00029-0"},{"key":"e_1_3_2_12_2","doi-asserted-by":"publisher","DOI":"10.1093\/intimm\/dxh125"},{"key":"e_1_3_2_13_2","doi-asserted-by":"publisher","DOI":"10.1128\/JVI.76.15.7799-7811.2002"},{"key":"e_1_3_2_14_2","doi-asserted-by":"publisher","DOI":"10.1080\/13550280290049697"},{"key":"e_1_3_2_15_2","doi-asserted-by":"publisher","DOI":"10.3109\/13550289709015793"},{"key":"e_1_3_2_16_2","doi-asserted-by":"publisher","DOI":"10.1038\/ng1827"},{"key":"e_1_3_2_17_2","doi-asserted-by":"publisher","DOI":"10.1016\/0378-1119(91)90434-D"},{"key":"e_1_3_2_18_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.7146898"},{"key":"e_1_3_2_19_2","doi-asserted-by":"publisher","DOI":"10.1093\/emboj\/20.23.6899"},{"key":"e_1_3_2_20_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.0605375103"},{"key":"e_1_3_2_21_2","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.neuro.29.051605.113014"},{"key":"e_1_3_2_22_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0025-6196(12)60865-9"},{"key":"e_1_3_2_23_2","doi-asserted-by":"publisher","DOI":"10.1002\/ana.410130409"},{"key":"e_1_3_2_24_2","doi-asserted-by":"crossref","first-page":"5699","DOI":"10.4049\/jimmunol.157.12.5699","volume":"157","year":"1996","unstructured":"Rodriguez, M., K.
