Phagocytosis of myelin sheath fragments by dendrites

Experimental Brain Research, 1987
In serial ultrathin sections of the frog spinal cord, profiles of dendritic appearance were identified that contained myelin fragment inclusions and received synaptic contacts. In a number of cases it could be established that the inclusions were derived from adjacent myelin sheaths.

Evolution of myelin sheaths: Both lamprey and hagfish lack myelin

Neuroscience Letters, 1984
Modern views of agnathan phylogeny consider Petromyzoniformes and Myxiniformes to belong to distinct classes that diverged from a common ancestor at a remote period, perhaps in the lower Cambrian, greater than 600 million years ago. Both are more primitive than elasmobranchs, holocephalans and bony fishes.

Function of tetraspan proteins in the myelin sheath

Current Opinion in Neurobiology, 2000
During the past few years, significant advances have been made in elucidating the mechanisms by which point mutations and altered gene dosages in tetraspan genes cause neurological disease. In addition, several new myelin tetraspans have been identified that are involved in adhesion, molecular trafficking, growth regulation, and migration of ...

Calcium control of myelin sheath growth

Nature Neuroscience, 2017
New studies provide compelling evidence that the number and length of myelin sheaths generated by oligodendrocytes in the CNS are controlled by local calcium levels, linking axonal activity to individual myelin sheath formation.

Pathology of the myelin sheath

1995
Abstract Diseases affecting the myelin sheath encompass a wide variety of clinical and experimental conditions. This chapter discusses the essentials of the processes of demyelination and remyelination, and relates these to multiple sclerosis (MS).

Perikaryal Myelin Sheaths

1981
The presence of a myelin sheath around nerve cell bodies in some sensory ganglia was first mentioned by Wagner (1846, quoted by Munzer 1931) and Bidder (1847). However, these authors did not appreciate the exact meaning of their finding. A little later, Leydig (1851) not only described the myelin sheath enveloping the nerve cell bodies in the ...

Concepts in Myelin Sheath Evolution

2001
Abstract What were the evolutionary pressures that led to the recent (in evolutionary terms) invention of the morphologically complex, biochemically unique and functionally essential vertebrate myelin sheath? It is frustrating that a definitive answer to this question may remain elusive.
