Distinct Ultrastructural Phenotypes of Glial and Neuronal Alpha-Synuclein Inclusions in Multiple System Atrophy

Different Ultrastructural Phenotypes of α-Synuclein Inclusions in Glia and Neurons in Brain Regions of Multiple System Atrophy (MSA) Introduction Multiple System Atrophy (MSA) is a severe neurodegenerative disease characterized by abnormal accumulation of α-Synuclein (α-Syn) in specific brain regions, forming pathological inclusions that primarily ...

KATP Channel Mutation Disrupts Hippocampal Network Activity and Nocturnal Gamma Shifts

KATP Channel Mutation Disrupts Hippocampal Network Activity and Nocturnal Gamma Wave Changes Research Background ATP-sensitive potassium (KATP) channels are crucial ion channels that link cellular metabolism with electrical activity. Studies have shown that high activity of KATP channels is closely related to a rare disease—Developmental delay, Epi...

Low-Intensity Ultrasound Ameliorates Brain Organoid Integration and Rescues Microcephaly Deficits

Low-intensity Ultrasound Promotes Brain Organoid Integration and Improves Microcephaly Defects Background of the Study Brain organoids are generated through the differentiation of pluripotent stem cells (PSCs) and exhibit impressive cellular diversity, capable of mimicking functional networks similar to the human brain. These organoid methods hold ...

Genetics Impact Risk of Alzheimer's Disease through Mechanisms Modulating Structural Brain Morphology in Late Life

In recent years, Alzheimer’s disease (AD) has become a significant health problem affecting the elderly population worldwide. Its related neuropathological changes can begin decades before the appearance of clinical symptoms. To explore more comprehensively the relationship between AD risk and brain morphology, a research team conducted a bidirecti...

Neuroanatomical and Prognostic Associations of Depression in Parkinson's Disease

This is a large-scale prospective cohort study on depression in patients with Parkinson’s disease (PD). Researchers have used the vast cohort data from the UK Biobank to investigate the temporal association between depression and the onset of PD, the relationship between depression and brain region structure in PD patients, and the impact of depres...

Unsupervised restoration of a complex learned behavior after large-scale neuronal perturbation

This paper reports on research investigating how zebra finches recover their complex learned behaviors following large-scale neuronal perturbations. The researchers selectively disrupted the activity of the projection neurons in the HVC (hyperpallium ventralis) region critical for song sequence generation in zebra finches using genetic tools, leadi...

The subcommissural organ regulates brain development via secreted peptides

The subcommissural organ regulates brain development via secreted peptides

I. Research Background and Purpose The subcommissural organ (SCO) is a glandular structure located at the entrance of the ventricular system, which is present in humans and other vertebrates, but its function has not been fully elucidated. Previous studies have suggested that the SCO may be involved in the regulation of neural development and the m...

Messenger RNA transport on lysosomal vesicles maintains axonal mitochondrial homeostasis and prevents axonal degeneration

Messenger RNA transport on lysosomal vesicles maintains axonal mitochondrial homeostasis and prevents axonal degeneration

This study utilized induced pluripotent stem cell (iPSC)-derived neurons to investigate the critical role of lysosome-related vesicles in axonal mRNA transport and mitochondrial homeostasis maintenance. By knocking out BORC subunits (borcs5 or borcs7) to block the entry of lysosome-related vesicles into axons, researchers found that this led to a s...

The transcription factor Meis2 promotes the development of projection neurons during mouse embryonic development by binding to and activating projection neuron-specific enhancers with Dlx5

This study investigated the role of the transcription factor Meis2 in regulating the development and differentiation of γ-aminobutyric acid (GABA)ergic neurons during mouse embryonic development. Researchers comprehensively applied techniques such as CRISPR/Cas9 knockdown, single-cell RNA sequencing (scRNA-seq), and lineage tracing, and found that ...
