The other is that the virus itself directly attacks neural cells and destabilizes the myelin sheath around them or damages axons to cause GBS.

A moderate stretch to an axon, Smith recently found, causes the sodium channels to malfunction.
There are two categories of CMT: those caused by the loss of axons in the peripheral nerves (CMT2) and those characterized by a malfunction in the Schwann cells that make up the myelin sheath, the protective coating that surrounds the nerve fibers and allows them to conduct nerve signals at high speeds (CMT1).
Viral DNA that jumped into our ancestors» genes millions of years ago may contribute to the chewed up axons (blue cylinders) that cause multiple sclerosis.
MS is a debilitating neurological disease caused by the destruction of oligodendrocytes, cells that build the myelin sheaths that surround the signal transmitting axons of neurons.
«In this case, the loss of axons is not caused by disease,» DiAntonio said.
Our goal is to use a new imaging system to monitor damage caused by AD to the brain region that contains the insulated axons (analogous to cables) connecting the neuron cell bodies (analogous to the central processing unit of a computer).
This disruption causes a change in the way light interacts with the tissue, such that the axon bundles exhibit less birefringence and also lower reflectance (back scatter).
