| Research Abstract |
LDM is the only cytochrome P450 enzyme that is involved in cholesterol biosynthesis and is expressed in central and peripheral myelin-forming cells, oligodendroglia and Schwann cell. Immunohistochemical analysis and Western blot analysis combined with laser capture microdissection using anti-LDM antibody revealed that LDM-immunoreactivity (IR) reached its peak at the stage of myelination, postnatal 2-3 weeks. The same kind of analyses indicated that LDM-IR in the white matter increased during the processes of remyelination following demyelination induced in mice by feeding diet containing cuprizone that injures oligodendroglia. To examine the possibility to treat demyelinating disorder by the upregulation of LDM, transgenic mice were raised using PLP gene-promoter, which express high level of LDM specifically in oligodendroglia.
