American Academy of Neurology sums up scientific highlights from 57th annual meeting

...owed that when immune cells destroy the insulating myelin around neurons, a molecule called 7-ketocholesterol is released. This molecule may stimulate other immune cells to attack the neuron. Understanding this important step may help design therapies to block it. [S12.004] Meanwhile, researchers from the U...

Why good cells go bad in progression of MS

...at during MS, renegade T-effector cells damage the myelin coating that covers nerve cells, causing the disease's symptoms. While another subset of white blood cells called T-regulatory cells normally control the activation of T-effector cells, investigators found that the chemical messenger interleukin-12 o...

...focus of research in the past century has been the myelin that insulates nerve fibers, and the cell that manufactures myelin, known as the oligodendrocyte," said Lennon. The Mayo Clinic group's work reveals that the protein targeted by the NMO antibody is not a component of myelin, or of oligodendrocytes. A...
