Article Abstract
The pathological microenvironment following peripheral nerve injury (PNI) comprises a dynamic interplay of cellular and molecular events that critically influence neuronal regeneration and functional recovery. Recent advances in nanotechnology have demonstrated the transformative potential of nanomaterials (NMs) in nerve repair, capitalizing on their unique physicochemical properties to engineer a pro-regenerative milieu that facilitates axonal regrowth. This review systematically explores the biological mechanisms by which NMs modulate and remodel the injury niche, thereby enhancing peripheral nerve regeneration (PNR). Specifically, this review highlights five key microenvironmental regulators, including rebuilding remyelinating Schwann cells, balancing the immune microenvironment, forming blood vessels, constructing extracellular matrix, and regulating cytokines and hormones. By analyzing these NMs-mediated therapeutic strategies, we provide novel mechanistic insights and discuss translational opportunities for next-generation nanomedicine in PNR therapy.

Oligodendrocytes, the myelinating cells of the central nervous system (CNS), are essential for the formation of myelin sheaths and pivotal for maintaining axonal integrity and conduction. Disruption of these cells and the myelin sheaths they produce is a hallmark of demyelinating conditions like multiple sclerosis or those resulting from certain drug side effects, leading to profound neurological impairments. In this study, we created a human brain organoid comprising neurons, astrocytes, and myelinating oligodendrocytes.

Unilateral facial palsy, a common type of facial paralysis, profoundly impacts individuals' daily functionality and quality of life. The current clinical diagnosis of facial paralysis primarily relies on the subjective judgment of doctors, and the development of automated detection methods is challenged by the lack of publicly available facial paralysis datasets and the inability to analyze different facial nerve branches. To address these problems, we propose a new benchmark named UPFG-SG for Unilateral Peripheral Facial Paralysis Severity Grading.

Background: Peripheral nerve injury commonly results in pain and long-term disability for patients. Recovery after in-continuity stretch or crush injury remains inherently unpredictable. However, surgical intervention yields the most favorable outcomes when performed shortly after injury.

Objective: To analyze the filum terminale (FT) of children with tethered cord syndrome (TCS) and aborted fetuses without neurological disorders in order to investigate the expression of significantly differentially expressed proteins in the FT under both pathological and physiological conditions.
Methods: According to the inclusion and exclusion criteria, 35 FT samples were selected, and the samples were subjected to immunohistochemistry and H&E staining. The data were analyzed using one-way analysis of variance, and P < 0.

Purpose: To characterize corneal immune cell morphodynamics and nerve features, and define the in vivo immune landscape in older adults with human immunodeficiency virus (HIV) receiving antiretroviral therapy (ART), relative to healthy age-matched adults.
Methods: In this cross-sectional study, 16 HIV-positive individuals receiving ART and 15 age-matched controls underwent ocular surface examinations and functional in vivo confocal microscopy (Fun-IVCM). Time-lapsed videos were created to analyze corneal immune cells (T cells, dendritic cells [DCs], macrophages).
