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...

Identification of senescent, TREM2-expressing microglia in aging and Alzheimer's disease model mouse brain

Identification of senescent, TREM2-expressing microglia in aging and Alzheimer's disease model mouse brain

Alzheimer’s disease (AD) is an age-related chronic neurodegenerative disorder, whose pathological mechanism involves multiple factors, including brain inflammation. Microglia, particularly those expressing the AD risk gene TREM2, are believed to play a crucial role in the development of AD, but their exact contribution has not been fully elucidated...

Targeting pathological cells with senolytic drugs reduces seizures in neurodevelopmental mTOR-related epilepsy

This is a research report on focal cortical dysplasia (FCD) type II. The authors aim to investigate the cellular senescence phenomenon present in FCD II and whether targeting these senescent cells can alleviate seizures. Background: FCD II is a common cortical malformation causing childhood epilepsy and developmental delay. It is caused by somatic ...

Assessing the contribution of the chemical exposome to neurodegenerative disease

Assessing the contribution of the chemical exposome to neurodegenerative disease

Assessing the Risks of Chemical Exposures for Neurodegenerative Diseases Introduction In recent years, many environmental chemicals, from solvents to pesticides, have been implicated in the development and progression of neurodegenerative diseases. However, a systematic approach akin to genome-wide association studies, which have identified dozens ...

Single-cell long-read sequencing-based mapping reveals specialized splicing patterns in developing and adult mouse and human brain

Single-cell sequencing technology reveals unique splicing patterns in developing and adult mouse and human brains In the nervous system, the splicing patterns of messenger RNA (mRNA) play a critical role in establishing cellular identity and regulating cellular functions. However, a comprehensive atlas depicting the mRNA splicing patterns across br...

Cortical gene expression architecture links healthy neurodevelopment to the imaging, transcriptomics and genetics of autism and schizophrenia

Linking Healthy Neurodevelopment with Imaging, Transcriptomic, and Genetic Associations in Autism Spectrum Disorder and Schizophrenia: A Study of Cortical Gene Expression Patterns Background: How does the complex anatomy and functional organization of the human brain develop from the expression of more than 20,000 genes? And how does this process g...
