WebThe myelin sheaths, which are lipid-rich, multilamellar membrane stacks and are produced by oligodendrocytes, are crucial for electric insulation and viability of neurons. The protein and lipid composition of myelin is very peculiar. In fact, the lipid composition of myelin varies significantly from other biological membranes. Webmarmoset—an established animal model for MS (10)—the lipid composition changes, in particular the ratios of charged to uncharged lipids (Table 1). In other studies, both the charged lipid and MBP isomer composition and the balance (relative amounts) between the charged lipid and MBP isomer compo-sition change in MS and EAE tissues (11, 12).
