Transgenic mice, which express active Fyn tyrosine kinase under the control of a glial fibrillary acidic protein promoter, have been produced. This promoter induces protein expression in the initiation stage of myelination in the peripheral nervous system (PNS) "Phosphorylation of cytohesin-1 by Fyn is required for initiation of myelination and the extent of myelination during development (Yamauchi et al., 2015 [1])". Herein we provide the data regarding myelination-related protein markers and myelin ultrastructure in transgenic mice.

Neurotoxicity is a common and potentially severe adverse effect from conventional and novel cancer therapy. The mechanisms that underlie clinical symptoms of central and peripheral nervous system injury remain incompletely understood. For conventional cytotoxic chemotherapy or radiotherapy, direct toxicities to brain structures and neurovascular damage may result in myelin degradation and impaired neurogenesis, which eventually translates into delayed neurodegeneration accompanied by cognitive symptoms.

Peripheral nerve injury (PNI) is notoriously difficult to repair due to impaired axonal regeneration and dysregulated inflammatory microenvironments. This study demonstrates that crocin facilitates peripheral nerve regeneration by modulating the STAT3/Bcl-2/Beclin-1 signaling axis, enhancing autophagy while suppressing NLRP3 inflammasome-mediated pyroptosis. In a rat model of sciatic nerve crush injury, crocin treatment improved axonal regrowth and ultrastructural remyelination, as evidenced by upregulated expression of β3-Tubulin, neurofilament-200 (NF200), and myelin basic protein (MBP), alongside significantly elevated sciatic functional index (SFI) scores, reduced muscle atrophy, and diminished collagen deposition.

Glial cells are essential regulators of brain homeostasis by orchestrating neuronal function, metabolism and immune responses. However, much less is known about peripheral glial cells, particularly those in the heart. This review explores the development, types and functions of cardiac glial cells, including Schwann cells, satellite glial cells and recently identified cardiac nexus glia, with some reference to their central nervous system counterparts.

Charcot-Marie-Tooth disease (CMT) is an inherited peripheral neuropathy characterized by sensory dysfunction and muscle weakness, manifesting in the most distal limbs first and progressing more proximal. Over a hundred genes are currently linked to CMT with enrichment for activities in myelination, axon transport, and protein synthesis. Mutations in tRNA synthetases cause dominantly inherited forms of CMT and animal models with CMT-linked mutations in these enzymes display defects in neuronal protein synthesis.
