axons

Are myelin and axons 'talking' to each other — and what are they saying?

MDA-supported research in Charcot-Marie-Tooth disease is focused on figuring out what goes wrong at the molecular level in CMT-affected axons or the myelin sheaths that surround them, rather than on attempting to fix the problem directly or preserving nerve function in spite of it. A central theme emerging from the last decade of research is that myelin and axons require constant signals from...

As recently as the early 1990s, many experts hoped that understanding just a few genes that influenced the development or maintenance of myelin or axons would explain all of Charcot-Marie-Tooth disease. It didn’t turn out to be that simple, however. Today, there are dozens of genes recognized that, when flawed, can cause CMT.
