Chronic Evoked Seizures in Young Pre-symptomatic APP/PS1 Mice Induce Serotonin Changes and Accelerate Onset of Alzheimer’s Disease-Related Neuropathology

APP/PS1 Mouse Study Reveals Link Between Chronic Induced Epilepsy and Alzheimer’s Disease Background Alzheimer’s Disease (AD) is the most common type of dementia globally, affecting over 55 million people. The typical pathological feature of AD is the deposition of amyloid-β (Aβ) in the brain. Although Aβ deposition and the mechanisms it triggers p...

Central C3a Receptor Modulates LPS-Induced Depressive-like Behaviors

The Regulatory Mechanism of Central Complement C3a Receptor on LPS-Induced Depressive-Like Behavior Introduction With the increasing number of depression patients globally, major depressive disorder (MDD) has become one of the leading causes of disability worldwide. The symptoms, treatment effects, and biological correlations of depression exhibit ...

Atypical Connectome Topography and Signal Flow in Temporal Lobe Epilepsy

Atypical Connectome Topography and Signal Flow in Temporal Lobe Epilepsy

Epilepsy is one of the most common neurological disorders, with temporal lobe epilepsy (TLE) being the most prevalent form of drug-resistant epilepsy in adults. Numerous studies have indicated that TLE involves not only pathological changes in the medial temporal lobe but also affects widespread brain structures and functions. In this scientific re...

Decoding the Influence of Central LEAP2 on Food Intake and Its Effect on Accumbal Dopamine Release

Analysis of the Effect of Central LEAP-2 on Food Intake and Its Impact on Nucleus Accumbens Dopamine Release Background Introduction Gut-brain peptides such as ghrelin and their receptors have been established as important factors in regulating hunger and reward processing. However, the liver-expressed antimicrobial peptide 2 (Leap2), an inverse ag...

Control of goal-directed and inflexible actions by dorsal striatal melanocortin systems, in coordination with the central nucleus of the amygdala

This academic paper, authored by researchers Elizabeth C. Heaton, Esther H. Seo, Laura M. Butkovich, Sophie T. Yount, and Shannon L. Gourley, primarily explores the role of the melanocortin system in the dorsal striatum in controlling goal-directed behavior and inflexible behavior, particularly in inhibiting habitual behavior in the dorsolateral st...

Genome-Wide Repeat Landscapes in Cancer and Cell-Free DNA

A Panoramic View of Whole Genome Repetitive Sequences in Cancer and Circulating Free DNA Research Background and Significance Throughout the development of cancer and other diseases, genetic changes in repetitive sequences within the genome are a significant characteristic. However, standard sequencing methods struggle to effectively characterize t...

Multimodal MRI Reveals Brainstem Connections That Sustain Wakefulness in Human Consciousness

Multimodal MRI Reveals Brainstem Connections That Sustain Wakefulness in Human Consciousness

Major Breakthrough in Brain Science: Multimodal MRI Reveals Brainstem Connectivity Maintaining Human Consciousness and Wakefulness Background Introduction Consciousness comprises two fundamental components: wakefulness and awareness. Despite significant progress in understanding the cortical networks related to consciousness over the past two decad...

Nociceptor Spontaneous Activity is Responsible for Fragmenting Non-Rapid Eye Movement Sleep in Mouse Models of Neuropathic Pain

Research Background and Motivation Neuropathic pain is a complex and common clinical issue, accompanied by persistent spontaneous pain. Patients often report symptoms such as spontaneous pain, electric shock sensations, and burning pain. The physiological mechanisms behind this type of pain are complex, and reliable research models or biomarkers ar...

Neuronal population activity in the olivocerebellum encodes the frequency of essential tremor in mice and patients

Encoding of Cerebellar-Olivary Neuronal Ensemble Activity for Tremor Frequency in Mice and Patients with Essential Tremor Research Background Essential Tremor (ET) is a common movement disorder characterized primarily by action tremor, affecting about 20% of the elderly population. The frequency and intensity of tremor are core features of ET. Howe...

Attenuation of Fibroblast Activation and Fibrosis by Adropin in Systemic Sclerosis

Reducing Fibroblast Activation and Fibrosis in Systemic Sclerosis through Adropin Fibrotic diseases of the skin and other organs have become significant socioeconomic challenges in modern society, and current treatment options are limited. This background for this study seeks to address the problem of fibrosis in Systemic Sclerosis (SSc), with the ...
