Outline of Final Research Achievements |
TMEV-IDD, a demyelinating disease of the central nervous system caused by Theiler murine encephalomyelitis virus, (TMEV) infection, is a model of multiple sclerosis (MS) in humans. By comparing TMEV-bound and TMEV-unbound cells, we found that ganglioside and sialic acid-bound N-glycans were less abundant in TMEV-unbound cells. In addition, we found a new candidate protein for the TMEV receptor and the involvement of sialic acid modification in TMEV binding.

Academic Significance and Societal Importance of the Research Achievements |
TMEV感染による脱髄疾患の発症機序の解明や病態の制御は、MSの理解や治療法について新たな知見を与えるものと期待される。したがってTMEVの感染受容体の同定は重要である。近年、TMEV感染による心筋炎モデルや、てんかん発作モデルが報告されており、本研究において見出した受容体候補タンパク質のさらなる解析により、これら疾患の理解や病態制御に新たな知見が得られることが期待される。
