The Myelin Sheath: Shape, Size ... leaving axons and even the entire neuron vulnerable to degeneration. Thus, patients with demyelinating diseases suffer from various neurological symptoms.

A marathon taxes more than just muscles—it pushes the brain to its metabolic limits. New research shows that during extreme ...

The research is published in the journal Science. Most nerve fibers in vertebrates are encased in sheaths made largely of myelin, a protein that protects the fibers and greatly enhances the ...

A new study has identified the protein hnRNP A1 as a key player in the production and maintenance of myelin, the fatty sheath that insulates nerve fibers in the brain.

Multiple sclerosis, a neuroinflammatory disease that affects nearly 3 million people worldwide, causes a loss of myelin, the fatty sheath that ... this process causes neuron damage.

Neuron Function Synapses Neural synapses are junctions between ... As the voltage increases along the axon, additional sodium channels open, propagating the signal. The myelin sheath made of protein ...

‘Scientists have discovered the crucial role of the hnRNP A1 molecule in maintaining #myelin sheath integrity. Could this be a new avenue for understanding #schizophrenia? #Neuroscience # ...

Myelin is a fatty substance produced by oligodendrocytes (cells of the central nervous system) that forms a sheath, like a kind of "insulator." It "protects" the extensions of neurons (axons ...

The APOE4 variant causes cholesterol buildup in the cells that make protective fatty sheaths for neurons ... while genes associated with myelin production were downregulated. “What we saw from the ...

A long fibre (axon) which is insulated by a fatty (myelin) sheath. They are long so they can carry messages up and down the body. Tiny branches (dendrons) which branch further as dendrites at each ...
