WebThe accumulation of these galactolipids causes damage to myelin-forming cells, which impairs the formation of myelin and leads to demyelination in the nervous system. Without myelin, nerves in the brain and other parts of the body cannot transmit signals properly, leading to the signs and symptoms of Krabbe disease. WebWhile the myelin structure formed by oligodendrocytes and Schwann cells has a similar ultrastructure, it is not composed of an identical set of proteins. While central and peripheral myelin share the basic protein myelin, the peripheral nervous system lacks myelin associated glycoprotein or proteolipid protein, but expresses the protein P0 and PMP22.

Web8 mei 2024 · This arrangement is in contrast to oligodendrocytes, the myelinating cell of the central nervous system (CNS), which form myelin sheaths for multiple surrounding axons.
