Rab27a/Slp2-a complex is involved in Schwann cell myelination

, 2016
Myelination of Schwann cells in the peripheral nervous system is an intricate process involving myelin protein trafficking. Recently, the role and mechanism of the endosomal/lysosomal system in myelin formation were emphasized.

Evaluating the Influence of Injury‐Induced Microstructural Variations on the Efficacy of a Diffusion MRI‐Derived Axon Diameter Surrogate

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To investigate the utility of a recently demonstrated diffusion MRI derived axon diameter surrogate measure (∆D⟂) under pathologic conditions induced by a spinal cord injury model. Methods Contusion injuries were performed on the thoracic–lumbar spinal cord of adult male rats.

The Role of Dystroglycan in Central Nervous System Myelination

, 2015
Dystroglycan, a membrane receptor linking the extracellular matrix to the inner cell cytoskeleton, is predicted to regulate the formation of myelin sheath in the Central Nervous System (CNS).

SNR‐Efficient Inhomogeneous Magnetization Transfer (ihMT) for Clinical Applications at 7 T

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Inhomogeneous MT (ihMT) is an MRI modality sensitive to Myelin, the lipid‐rich membrane surrounding the axons. A novel ihMT saturation strategy and its associated B1+$$ {\mathrm{B}}_1^{+} $$ correction at UHF are proposed. The aim is to generate a strong ihMT effect within a clinically compatible scan time while complying with SAR ...

Administration of Schwann Cell‐Like Cells Differentiated From Tonsil‐Derived Mesenchymal Stem Cells Promotes Peripheral Nerve Regeneration by Inducing Macrophage Polarization in a Chronic Constriction Injury Model

Muscle &Nerve, EarlyView.
TMSC‐SCs were mixed with fibrin adhesive and administered into the sciatic nerve of CCI rats, and nerve conduction studies and histopathological observations confirmed the regeneration of the peripheral nerve and gastrocnemius muscle. In addition, the expression of M1 and M2 macrophage markers was observed after the administration of TMSC‐SCs. ABSTRACT

Depletion of microglial compensation in glial network: Disease‐associated response dynamics in the revised amyloid hypothesis

Neuroprotection, EarlyView.
The critical transition from amyloid pathology to irreversible neuronal loss in Alzheimer's disease hinges on the microglial response. This review aims to systematize the patterns of how microglia react within the glial context. Abstract Microglia mount coordinated, stage‐dependent compensatory programs in response to early amyloid β (Aβ) accumulation ...

Predicting brain age in children aged 2–6 years with autism spectrum disorders using routine T1‐ and T2‐weighted magnetic resonance imaging

Pediatric Investigation, EarlyView.
The routine magnetic resonance imaging‐based model accurately predicted brain age in children aged 2–6. Children with autism spectrum disorder (ASD) exhibited maturational delays at ages 3–5, shifting toward accelerated aging by age 5–6. This exploratory result highlights the dynamic, age‐related developmental heterogeneity in ASD.

Effects of Tributyltin Chloride on Human Neuronal Differentiation and Mice Brain Development

Environmental Toxicology, EarlyView.
ABSTRACT According to the developmental origins of health and disease hypothesis, perinatal exposure to an environmental toxicant during the development of the nervous system could cause a permanent cellular modification that may promote the appearance of neurodegenerative diseases at an older age.

Integrated Methylome–Transcriptome Analysis Reveals Epigenomic Remodeling and Rho GTPase–Linked Immune–Epithelial Crosstalk in Atopic Dermatitis

Allergy, EarlyView.
Integrated methylome–transcriptome–microbiome analysis of AD skin identified thousands of DMRs. Rho GTPase signaling and actin–junctional programs emerged as central hubs integrating immune, epithelial, and microbial interactions in the pathogenesis of atopic dermatitis.

Iron Physiology and Its Impact on Atopic Diseases: An EAACI Taskforce Report

Allergy, EarlyView.
ABSTRACT Iron is essential for oxygen transport, energy metabolism, and immune regulation. Yet iron deficiency is the most common micronutrient disorder across all age groups, affecting nearly one quarter of the global population. Iron deficiency triggers nutritional immunity, a host defense mechanism that withholds and redistributes iron, contributing
