Increased Numbers of CD4+ T‐Cells in the Hypocretin/Orexin Region of Narcolepsy Type 1

Annals of Neurology, EarlyView.
Narcolepsy type 1 (NT1) is presumed to be an autoimmune disorder caused by hypothalamic loss of hypocretin (Hcrt; orexin). In postmortem NT1 brains, we observed an 11‐fold increase of CD4+ T‐cells in the Hcrt region compared with control hypothalami, without a corresponding rise in CD8+ T‐cells.

Predominance of Ferroptotic Cell Death Mechanisms in Substantia Nigra Neurodegeneration in Parkinson's Disease

Annals of Neurology, EarlyView.
Objective The extent of neuronal loss in Parkinson's disease (PD) and the pathogenic processes underlying neuronal dysfunction and loss remain poorly understood. Here, we analyzed the expression of key molecules representing different cell death signaling pathways and their association with Lewy pathology, dopaminergic (DA) neuron loss and stage of PD ...

Human Induced Pluripotent Stem Cells Improve Stroke Outcome and Reduce Secondary Degeneration in the Recipient Brain

Cell Transplantation, 2012
Human induced pluripotent stem cells (hiPSCs) are a most appealing source for cell replacement therapy in acute brain lesions. We evaluated the potential of hiPSC therapy in stroke by transplanting hiPSC-derived neural progenitor cells (NPCs) into the ...

Gait Abnormalities in Parkinson’s Disease Are Associated with Extracellular Free-Water Characteristics in the Substantia Nigra

Journal of Parkinson’s Disease, 2022
Background: Gait impairments are common in Parkinson’s disease (PD). The pathological mechanisms are complex and not thoroughly elucidated, thus quantitative and objective parameters that closely relate to gait characteristics are critically needed to ...

Nanomaterial‐Mediated Near‐Infrared Photothermal Neuromodulation for Neurologic Disorders

Advanced NanoBiomed Research, EarlyView.
This review summarizes how near‐infrared light activates photothermal nanomaterials to enable noninvasive neuromodulation with high spatiotemporal precision. It elucidates the underlying mechanisms, explores targeted therapeutic applications for neurological disorders, discusses integration with optogenetics and biosensors, and addresses future ...

Dopaminergic neurodegeneration in the substantia nigra is associated with olfactory dysfunction in mice models of Parkinson’s disease

Cell Death Discovery, 2023
Olfactory dysfunction represents a prodromal stage in Parkinson’s disease (PD). However, the mechanisms underlying hyposmia are not specified yet.

Moving beyond neurophobia to cultivate the neuroquisitive learner

Anatomical Sciences Education, EarlyView.
Abstract “Neurophobia,” a pervasive fear of the neurological sciences, poses a significant barrier in medical education, affecting learners and physicians worldwide. Its consequences are far‐reaching, contributing to a limited neurology workforce and diminished confidence among non‐specialists in managing neurological conditions.

Substantia nigra ultrastructural pathology in schizophrenia [PDF]

Schizophrenia Research, 2018
Schizophrenia is a severe mental illness affecting approximately 1% of the population worldwide. Despite its prevalence, the cause remains unknown, and treatment is not effective in all patients. Dopamine is thought to play a role in schizophrenia pathology, yet the substantia nigra (SN), the origin of dopaminergic pathways, has not been studied ...
