Mitochondrial Import and Accumulation of α-Synuclein Impair Complex I in Human Dopaminergic Neuronal Cultures and Parkinson Disease Brain*

Journal of Biological Chemistry, 2008
α-Synuclein, a protein implicated in the pathogenesis of Parkinson disease (PD), is thought to affect mitochondrial functions, although the mechanisms of its action remain unclear.

Contribution of Addictovigilance data to assess adverse‐events linked to psychoactive substances in children and adolescents

British Journal of Clinical Pharmacology, EarlyView.
Aims We sought to characterize adverse events and deaths associated with the use of psychoactive substances in children and adolescents. Methods Two French Addictovigilance databases were analysed: spontaneous reports and deaths over the period 2016–2021, in subjects aged 10–<18 years. An unsupervised classification was implemented on consumption data (

Parkinson's Disease Assessment from a Wrist-Worn Wearable Sensor in Free-Living Conditions: Deep Ensemble Learning and Visualization [PDF]

arXiv, 2018
Parkinson's Disease (PD) is characterized by disorders in motor function such as freezing of gait, rest tremor, rigidity, and slowed and hyposcaled movements. Medication with dopaminergic medication may alleviate those motor symptoms, however, side-effects may include uncontrolled movements, known as dyskinesia.

Mitochondria and Endoplasmic Reticulum Contact Site as a Regulator of Proteostatic Stress Responses in Neurodegenerative Diseases

BioEssays, EarlyView.
Recent findings indicate that mitochondria‐associated membranes (MAMs), where the endoplasmic reticulum directly contacts the mitochondria, are a novel microdomain essential for cellular homeostasis, including proteostasis. We summarize the disruption of protein homeostasis and MAM alteration in neurodegenerative diseases, then discuss challenges and ...

Cryopreservation practices in clinical and preclinical iPSC‐based cell therapies: Current challenges and future directions

Biotechnology Progress, EarlyView.
Abstract Induced pluripotent stem cells (iPSCs) offer significant therapeutic potential, but cryopreservation challenges, particularly the reliance on cytotoxic Dimethyl Sulfoxide (Me2SO), hinder their clinical application. This review examines current cryopreservation practices in clinical and preclinical iPSC‐based therapies, highlighting the ...

Transcription Factor-Mediated Generation of Dopaminergic Neurons from Human iPSCs—A Comparison of Methods

Cells
Dopaminergic neurons are the predominant brain cells affected in Parkinson’s disease. With the limited availability of live human brain dopaminergic neurons to study pathological mechanisms of Parkinson’s disease, dopaminergic neurons have been generated

Influence of nicotine and alcohol on sleep latency: the reward-attention circuit model [PDF]

arXiv, 2019
We previously developed a neurocomputational model called the reward-attention circuit, which has been used to investigate the separate effects of nicotine and alcohol on attention focus. The model is based on known circuits linking midbrain dopaminergic neurons to the thalamocortical loop and is sufficiently versatile to capture diverse phenomena.

Serotonergic Modulators in Alzheimer's Disease: A Hope in the Hopeless Condition

Chemistry &Biodiversity, EarlyView.
ABSTRACT Alzheimer's disease (AD) is the main cause of dementia worldwide. AD is a progressive brain neurodegenerative disease due to genetic and environmental factors that induce a progressive accumulation of intracellular hyperphosphorylated tau protein and extracellular amyloid protein (Aβ).
