Synaptic Neoteny of Human Cortical Neurons Requires Species-Specific Balancing of SRGAP2-SYNGAP1

I. Research Background: Neoteny in Human Brain Development and Neurodevelopmental Disorders One of the remarkable features of human brain development is the slow developmental pace of cortical neurons. Compared to other mammals, especially non-human primates, the developmental process of human cortical neurons can last for several years. This neote...

A Bimodal Taxonomy of Adult Human Brain Sulcal Morphology Related to Timing of Fetal Sulcation and Trans-Sulcal Gene Expression Gradients

A Bimodal Taxonomy of Adult Human Brain Sulcal Morphology Related to Timing of Fetal Sulcation and Trans-Sulcal Gene Expression Gradients

Research Background and Objectives This study focuses on the complex morphological features of the adult cerebral cortex sulci, specifically the classification of linear and complex morphologies of brain sulci and their developmental mechanisms. The sulci are groove structures on the surface of the cerebral cortex, corresponding to different geneti...

Gut-Induced Alpha-Synuclein and Tau Propagation Initiate Parkinson’s and Alzheimer’s Disease Co-Pathology and Behavior Impairments

Gastrointestinal-Induced Spread of α-Synuclein and Tau Proteins Triggers Comorbid Pathology and Behavioral Impairments in Parkinson’s and Alzheimer’s Diseases Background Parkinson’s Disease (PD) and Alzheimer’s Disease (AD) are two common neurodegenerative disorders, caused by the aggregation of α-synuclein (a-syn) and Tau protein in the brain, res...

Ferroptosis Triggered by Spliceosomal GTPase EFTUD2 Deficiency Leads to Purkinje Cell Degeneration

Depletion of EFTUD2 Triggers Ferroptosis-Induced Degeneration of Cerebellar Purkinje Cells Background and Motivation The cerebellum plays a crucial role in motor coordination and higher cognitive functions, with the health of cerebellar Purkinje cells (PCs) being essential for maintaining cerebellar function. Gene regulation based on alternative sp...

Disruption of Nuclear Speckle Integrity Dysregulates RNA Splicing in C9orf72-FTD/ALS

Disruption of Nucleolar Integrity and Dysregulation of RNA Splicing in C9orf72-FTD/ALS Background and Research Motivation The hexanucleotide repeat expansion (GGGGCC)n in the C9orf72 gene is the most common genetic cause of frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS). Studies have shown that these repeat sequences not only...

The Role of Motor Cortex in Striatal Motor Dynamics and Execution of Skilled and Unskilled Actions

Exploring the Crucial Role of the Motor Cortex in Basal Ganglia and Dynamic Motor Control Research Background and Motivation The role of the motor cortex (Motor Cortex, M1) in motor generation and regulation has long been a significant topic in neuroscience. The interaction between M1 and the striatum in selecting and executing goal-directed action...

Structural Basis of Psychedelic LSD Recognition at Dopamine D1 Receptor

Structural Basis of LSD Recognition in Dopamine D1 Receptors Research Background and Problem Statement LSD (lysergic acid diethylamide) is a well-known hallucinogen that primarily exerts profound cognitive and perceptual effects by acting on various neurotransmitter receptors, including serotonin (5-HT) receptors and dopamine receptors. The 5-HT2A ...

Endothelial Metabolic Control of Insulin Sensitivity Through Resident Macrophages

Endothelial Cells Influence Insulin Sensitivity Through Metabolic Regulation of Resident Macrophages In recent years, metabolic diseases, especially insulin resistance and diabetes, have become significant global health issues. Muscle tissue, being one of the main organs for glucose metabolism in the human body, has its insulin sensitivity closely ...

Metabolic Regulation of the Glioblastoma Stem Cell Epitranscriptome by Malate Dehydrogenase 2

Paper Report: The Role of MDH2 in Epitranscriptomic Metabolic Regulation of Glioblastoma Stem Cells Introduction and Background Glioblastoma (GBM) is the most common and lethal primary brain malignant tumor in adults. GBM cells utilize a metabolic pathway known as the Warburg effect, which involves increased glucose uptake through aerobic glycolysi...

Hexokinase 2 Senses Fructose in Tumor-Associated Macrophages to Promote Colorectal Cancer Growth

Hexokinase 2 Senses Fructose in Tumor-Associated Macrophages to Promote Colorectal Cancer Growth

Fructose Promotes Colorectal Cancer Growth by Modulating Tumor-Associated Macrophage Polarization Introduction In recent years, fructose intake has dramatically increased worldwide and is closely associated with obesity and metabolic syndrome, both of which are recognized risk factors for cancer development. Although previous studies have shown tha...
