In the vertebrate nervous system, the myelin sheath allows for rapid and efficient conduction of action potentials along axons. Despite the essential function of myelin, many questions remain unanswered about the mechanisms that govern the development of myelinated axons. The fundamental properties of myelin are widely shared among vertebrates, and the zebrafish has emerged as a powerful system to study myelination in vivo. This review will highlight recent advances from genetic screens in zebrafish, including the discovery of the role of kif1b in mRNA localization in myelinating oligodendrocytes.

Background: Prognostic biomarkers at multiple sclerosis (MS) onset to predict disease severity may help guide initial therapy selection for people with MS. Over 20 disease-modifying treatments (DMTs) of varying levels of risk and efficacy now exist. The ability to predict MS severity would help to identify those patients at higher risk where a highly effective, but potentially risky, therapy would be optimal.

Communication sound processing in mouse AC is lateralized. Both left and right AC are highly specialised and differ in auditory stimulus representation, functional connectivity and field topography. Previous studies have highlighted intracortical functional circuits that explain hemispheric stimulus preference.

In the central nervous system (CNS), myelinated axons vary over 100-fold in diameter, with conduction speed scaling linearly with increasing diameter. Axon diameter and myelination are closely interlinked, with axon diameter exerting a strong influence on myelination.

Chronic nerve compression disorders, such as carpal tunnel syndrome, are common and can significantly impair daily activities due to motor and sensory dysfunctions. Currently, no systemic pharmacotherapy exists for preventing or treating disease progression. This study aims to investigate whether Neurotropin®, an established analgesic, has therapeutic effects.

Introduction: Multiple Sclerosis (MS) is a complex auto-inflammatory disease affecting the brain and spinal cord, which results in axonal de-myelination and symptoms including fatigue, pain, and difficulties with vision and mobility. The involvement of the immune system in the pathology of MS is well established, particularly the adaptive T cell response, and there has been a particular focus on the IL-17-producing subset of Th17 cells and their role in driving disease. However, the importance of innate immune cells has not been so well characterised.
