Nasal Mucosa‐Derived Extracellular Vesicles as a Systemic Antiaging Intervention

open access: yesAdvanced Science, EarlyView.
This study shows that nasal mucosa‐derived extracellular vesicles (nmEVs) exert systemic anti‐ageing effects in mice by restoring circadian rhythm, suppressing cellular senescence, and improving cognitive function. In aged human bone marrow mesenchymal stem cells, nmEVs reverse senescence‐associated phenotypes and reactivate core clock gene expression.

Dopaminergic neurons promote hippocampal reactivation and spatial memory persistence

open access: yesNature Neuroscience, 2014
We found that optogenetic burst stimulation of hippocampal dopaminergic fibers from midbrain neurons in mice exploring novel environments enhanced the reactivation of pyramidal cell assemblies during subsequent sleep/rest.

Parabiosis, Assembloids, Organoids (PAO)

open access: yesAdvanced Science, EarlyView.
This review evaluates parabiosis, organoids, and assembloids as complementary disease models spanning systemic, organ, and multi‐organ levels. It highlights their construction strategies, applications, and current limitations, while emphasizing their integration with frontier technologies such as artificial intelligence, organ‐on‐a‐chip, CRISPR, and ...

Parkinson’s disease: animal models and dopaminergic cell vulnerability

open access: yesFrontiers in Neuroanatomy, 2014
Parkinson’s disease (PD) is a neurodegenerative disorder that affects about 1.5% of the global population over 65 years of age. A hallmark feature of PD is the degeneration of the dopamine (DA) neurons in the substantia nigra pars compacta (SNc) and the ...

Olfactory‐to‐Entorhinal Network Dysrhythmias Drive Parkinson's Cognitive Impairment Through Frequency‐Specific Oscillatory Decoupling

open access: yesAdvanced Science, EarlyView.
Wang et al reveal that in the olfactory system, the selective impairment of gamma‐driven Barcode features underlying early olfactory deficits, while the selective impairment of theta‐driven Barcode features underlying later cognitive deficits, further establishing cross‐network gamma oscillations in the early stage as a biomarker of later cognitive ...

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

open access: yesCells
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

Microglial Fkbp5 Impairs Post‐Stroke Vascular Integrity and Regeneration by Promoting Yap1‐Mediated Glycolysis and Oxidative Phosphorylation

open access: yesAdvanced Science, EarlyView.
A post‐stroke perivascular niche of microglia characterized by low expression of M2 markers and elevated glycolysis, oxidative phosphorylation (OXPHOS), and phagocytic activity is identified, which is termed stroke‐activated vascular‐associated microglia (stroke‐VAM).
