Subventricular Zone Microstructure in Pediatric-Onset Multiple Sclerosis.
Ann Neurol
January 2025
Neuroimaging Research Unit, Division of Neuroscience, IRCCS San Raffaele Scientific Institute, Milan, Italy.
Objective: The aim of this study was to explore the microstructural dynamics of the subventricular zone (SVZ) with aging and their associations with clinical disability and brain structural damage in pediatric-onset multiple sclerosis (MS) patients.
Methods: One-hundred and forty-one pediatric-onset MS patients (67 pediatric and 74 adults with pediatric-onset) and 233 healthy controls (HC) underwent neurological and 3.0 T MRI assessment.
Dysregulation of the Kynurenine Pathway in Relapsing Remitting Multiple Sclerosis and Its Correlations With Progressive Neurodegeneration.

Macquarie Medical School, Faculty of Medicine, Health and Human Sciences, Macquarie University, Sydney.
Background And Objectives: Despite the absence of acute lesion activity in multiple sclerosis (MS), chronic neurodegeneration continues to progress, and a potential underlying mechanism could be the kynurenine pathway (KP). Prolonged activation of the KP from chronic inflammation is known to exacerbate the progression of neurodegenerative diseases through the production of neurotoxic metabolites. Among the 8 KP metabolites, six of them, namely kynurenine (KYN), 3-hydroxylkynurenine (3HK), anthranilic acid (AA), kynurenic acid (KYNA), and quinolinic acid (QUIN), have been associated with neurodegeneration.

The choroid plexus (ChP) is a vital brain structure that produces cerebrospinal fluid (CSF) and forms a selective barrier between the blood and CSF, essential for brain homeostasis. Composed of secretory epithelial cells, connective stroma, and a fenestrated vascular network, the ChP supports nutrient transport, immune surveillance, and the clearance of toxic by-products. Despite its significance in maintaining cerebral function, the mechanisms underlying its development and maturation remain poorly understood.

Department of Neurology, University of Ulsan College of Medicine, Asan Medical Center, Seoul, Republic of Korea. Electronic address:
Background: The glymphatic system, essential for brain waste clearance, has been implicated in neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS). Emerging imaging markers, such as the analysis along the perivascular space (ALPS) index and choroid plexus volume (CPV), may provide insights into glymphatic function, but their relevance to ALS remains unclear.
Objective: To assess glymphatic dysfunction in ALS patients using the ALPS index and CPV.
