Schwann Cell Synthesized Cholesterol Orchestrates Peripheral Nerve Regeneration via Structural and IGF1‐Dependent Signaling Mechanisms

Advanced Science, EarlyView.
This study reveals that Schwann cell FDFT1‐mediated cholesterol synthesis is essential for peripheral nerve regeneration via dual roles: as a structural component for myelin and as a metabolic signal that upregulates IGF1. IGF1 promotes axonal growth through paracrine action and enhances Schwann cell differentiation/ myelination via an intrinsic IGF1R ...

Multimodal Enhancement of Remyelination by Exercise with a Pivotal Role for Oligodendroglial PGC1α

Cell Reports, 2018
Summary: Remyelination is a multistep regenerative process that results in the reformation of myelin sheaths around demyelinated axons and is a critical therapeutic target.

STING deficiency promotes motor recovery in mice following brachial plexus root avulsion

Animal Models and Experimental Medicine, EarlyView.
STING deficiency can increase the body weight, promote motor recovery, decrease MN death, inhibit pyroptosis and neuroinflammation, increase remyelination, and reduce the atrophy of the biceps brachii in mice with BPRA. Abstract Background Brachial plexus root avulsion (BPRA), a well‐known form of peripheral nerve injury, results in motor function loss

Depletion of Microglia Increases Cortical Oligodendrocyte Density During Remyelination. [PDF]

Glia
Cuprizone demyelination induces transient reactive states in deep cortical microglia (MG) through early recovery. Depleting MG in recovery increases the number of deep cortical mature/pre‐myelinating oligodendrocytes. Deep cortical reactive MG reduce oligodendrocyte density after demyelination.

From Diagnosis to Disease Staging: Multisite Validation of Cerebrospinal Fluid Molecular Tests in Multiple Sclerosis

Annals of Neurology, EarlyView.
Objective The growing demand for personalized treatment in multiple sclerosis (MS) highlights the need for more precise biomarkers that can outperform magnetic resonance imaging and clinical assessment in patient stratification. Advances in multiplex proteomic technologies suggest that cerebrospinal fluid (CSF) analysis at MS onset may not only improve

Circulating platelets modulate oligodendrocyte progenitor cell differentiation during remyelination

eLife
Revealing unknown cues that regulate oligodendrocyte progenitor cell (OPC) function in remyelination is important to optimise the development of regenerative therapies for multiple sclerosis (MS). Platelets are present in chronic non-remyelinated lesions

Endogenous Repair in Vanishing White Matter

Annals of Neurology, EarlyView.
Objective Vanishing white matter is a leukodystrophy with remarkable regional variation in disease severity. The cerebral and cerebellar white matter chronically degenerates, while stress‐induced episodes of rapid neurological deterioration coincide with the appearance of acute focal lesions in the deep gray structures and brainstem.

Topographical Variation of Iron‐Rimmed Lesions in the Multiple Sclerosis Brain and Spinal Cord: A Neuropathological Study

Annals of Neurology, EarlyView.
Paramagnetic‐rim lesions are a novel diagnostic marker in multiple sclerosis (MS) and are associated with poor prognosis due to their link with chronic inflammation and disease progression. Analyzing 46 postmortem MS cases, researchers found no iron rims in 67 white matter and 85 grey matter spinal cord lesions, despite most being active.

Myelitis‐Predominant Aggressive Phenotype: Unveiling Unique Patterns of Late‐Onset Neuromyelitis Optica Spectrum Disorders

Annals of Neurology, EarlyView.
Objective The objective of this study was to compare clinical features and prognosis of late‐onset neuromyelitis optica spectrum disorder (LO‐NMOSD, onset age ≥60 years) with adult‐onset NMOSD (AO‐NMOSD, onset age 18–59 years), and to provide insights for individualized management in elderly patients.
