Expanded CNS myelin sheaths formed in situ in the presence of an IgM antigalactocerebroside-producing hybridoma.
When O1 hybridoma cells, which produce an IgM antigalacto-cerebroside, are implanted into the dorsal columns of 4-8 d rat spinal cord, some of the myelin that subsequently develops in the immediate vicinity displays an abnormal periodicity. The spacings that are seen cluster at approximately 19 nm and 31 nm, roughly two and three times the normal 11 nm spacing. In the expanded sheaths, major de...
متن کاملReconstituted Myelin Sheaths Investigated by Neutron Scattering: the Role of Myelin Proteins
Myelin is a multilamellar membrane which, wrapping the nerve axons, increases the efficiency of nervous signal transmission. Indeed, the molecular components of the myelin sheath interact tightly with each other and molecules on the axonal surface to drive myelination, to keep both myelin and the axon intact, and to transduce signals from myelin to the axon and vice versa. Myelin is strongly af...
متن کاملA Radial Component of Central Myelin Sheaths
Gray (see Robertson (9, Fig. 25)) has observed the presence of a radial structure in the myelin sheaths of peripheral nerves, but so far this appears to be the only record of such a component. The purpose of the present article is to describe the occurrence and characteristics of a similar radial component in myelin sheaths from the optic nerves of rats, mice, and toads (Xenopus laevis). These ...

متن کاملBallooning of myelin sheaths in normally aged macaques.
In aged animal brains, a variety of "holes" are formed in the neuropil. One type of hole, here designated as the myelin balloon, is an abnormality of the myelin sheath and is found in a number of diverse sites in the brain. Profiles of myelin balloons display rather smoothly rounded peripheral contours and typically range up to 10 microm in diameter, although exceptionally large examples may be...
