Accumulation of 8,9-unsaturated sterols drives oligodendrocyte formation and remyelination
Many small molecules that stimulate oligodendrocyte formation act not through their canonical pathways but by inhibiting enzymes within the cholesterol biosynthesis pathway and thereby inducing the accumulation of 8,9-unsaturated sterols.

Structure of an integral membrane sterol reductase from Methylomicrobium alcaliphilum
Solving the X-ray crystal structure of a Δ14-sterol reductase and homologue of human C14SR and DHCR7, two enzymes that reduce specific carbon–carbon double bonds in the cholesterol biosynthetic pathway, may provide insight into how specific mutations in DHCR7 and lamin B receptor lead to human diseases.
