Myelin lipid metabolism and its role in myelination and myelin maintenance
The Innovation, 2023 Myelin is a specialized cell membrane indispensable for rapid nerve conduction. The high abundance of membrane lipids is one of myelin’s salient features that contribute to its unique role as an insulator that electrically isolates nerve fibers across ...

Current Biology, 2016 Myelin is a key evolutionary acquisition that underlay the development of the large, complex nervous systems of all hinged-jaw vertebrates. By promoting rapid, efficient nerve conduction, myelination also made possible the development of the large body size of these vertebrates.

Recognizing early MRI signs (or their absence) is crucial in diagnosing metachromatic leukodystrophy
Annals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 1999-2009, December 2022., 2022 Abstract Objectives Metachromatic leukodystrophy (MLD) has characteristic white matter (WM) changes on brain MRI, which often trigger biochemical and genetic confirmation of the diagnosis. In early or pre‐symptomatic disease stages, these typical MRI changes might be absent, hampering early diagnosis.

Is Myelin a Mitochondrion? [PDF]
Journal of Cerebral Blood Flow & Metabolism, 2012 It has been hypothesized that myelin acts like a mitochondrion, generating ATP across the membranes of its sheath. By calculating the proton motive force across the myelin membrane based on known values for the pH and membrane potential of the oligodendrocyte, we find that insufficient energy could be harvested from proton flow across the myelin ...

Lanthionine Ketimine Ethyl Ester Accelerates Remyelination in a Mouse Model of Multiple Sclerosis
ASN Neuro, 2022 Although over 20 disease modifying therapies are approved to treat Multiple Sclerosis (MS), these do not increase remyelination of demyelinated axons or mitigate axon damage.

Brain Sciences, 2022 Myelin in humans is composed of about 80% lipids and 20% protein. Initially, myelin protein composition was considered low, but various recent proteome analyses have identified additional myelin proteins.

BMC Pediatrics, 2022 Background Alexander disease (AxD) is classified into AxD type I (infantile) and AxD type II (juvenile and adult form). We aimed to determine the potential genetic cause(s) contributing to the AxD type II manifestations in a 9-year-old male who presented

Proteome Profile of Myelin in the Zebrafish Brain
Frontiers in Cell and Developmental Biology, 2021 The velocity of nerve conduction along vertebrate axons depends on their ensheathment with myelin. Myelin membranes comprise specialized proteins well characterized in mice.

Glia, 2017 AbstractMyelinating cells surround axons to accelerate the propagation of action potentials, to support axonal health, and to refine neural circuits. Myelination is metabolically demanding and, consistent with this notion, mTORC1—a signaling hub coordinating cell metabolism—has been implicated as a key signal for myelination.

A space-fractional cable equation for the propagation of action potentials in myelinated neurons [PDF]
Emerging Science Journal, Vol. 4, No. 3: 148-164, 2020, 2020 Myelinated neurons are characterized by the presence of myelin, a multilaminated wrapping around the axons formed by specialized neuroglial cells. Myelin acts as an electrical insulator and therefore, in myelinated neurons, the action potentials do not propagate within the axons but happen only at the nodes of Ranvier which are gaps in the axonal ...
