IGF-I Promotes Peripheral Nervous System Myelination

Peripheral nervous system plasmalogens regulate Schwann cell differentiation and myelination.

Rhizomelic chondrodysplasia punctata (RCDP) is a developmental disorder characterized by hypotonia, cataracts, abnormal ossification, impaired motor development, and intellectual disability. The underlying etiology of RCDP is a deficiency in the biosynthesis of ether phospholipids, of which plasmalogens are the most abundant form in nervous tissue and myelin; however, the role of plasmalogens i...

MicroRNA-23a promotes myelination in the central nervous system.

Demyelinating disorders including leukodystrophies are devastating conditions that are still in need of better understanding, and both oligodendrocyte differentiation and myelin synthesis pathways are potential avenues for developing treatment. Overexpression of lamin B1 leads to leukodystrophy characterized by demyelination of the central nervous system, and microRNA-23 (miR-23) was found to s...

“BACE1 dependent function of Neuregulin1 in peripheral nervous system myelination”

Profilin 1 is required for peripheral nervous system myelination.

Myelination allows rapid saltatory propagation of action potentials along the axon and is an essential prerequisite for the normal functioning of the nervous system. During peripheral nervous system (PNS) development, myelin-forming Schwann cells (SCs) generate radial lamellipodia to sort and ensheath axons. This process requires controlled cytoskeletal remodeling, and we show that SC lamellipo...

Sequence of central nervous system myelination in human infancy. I. An autopsy study of myelination.

This study establishes the sequence of myelination in a population of autopsied infants from birth through the second postnatal year. Myelination was assessed in 62 precisely defined central nervous system (CNS) sites of 162 infants with diverse diseases who were autopsied from 1972 to 1984 at Children's Hospital, Boston. The degree of myelination was graded on an ordinal scale of 0-4 using the...
