Case Report: Treatment of delayed tremor episodes in a patient with DPPX antibody encephalitis.

Introduction: Autoimmune encephalitis is a neurological disease caused by abnormal autoimmune mechanisms, characterized by a range of symptoms such as psychiatric and behavioral abnormalities, cognitive impairment, memory decline, and seizures. It is primarily identified by the presence of autoantibodies against neuronal surface antigens in the cerebrospinal fluid. This disease is relatively rare in clinical settings, and its diagnosis remains challenging, with fewer than a hundred cases reported to date.

Stem cell extracellular vesicles: a new dawn for anti-inflammatory treatment of neurodegenerative diseases.

Mesenchymal stem cell-derived extracellular vesicles, as carriers for intercellular communication, are rich in bioactive substances such as proteins and nucleic acids, and show unique potential in the treatment of neurodegenerative diseases. Their vesicular structure, with a diameter of 30-150 nm, can penetrate the blood-brain barrier and modulate the activity of microglia and astrocytes by delivering functional molecules. This process inhibits the release of pro-inflammatory factors and enhances the expression of anti-inflammatory mediators, thereby alleviating neuroinflammation in the pathological process of neurodegenerative diseases.

Decreases in Hormone Levels Modulate Neurovascular Coupling but Not Reduced Insular Functional Connectivity in Menstrual-Related Migraine.

Menstrual-related migraine (MRM) is a neurovascular disorder associated with decreased sex hormone levels. The menstrual cycle influences both cerebrovascular function and functional brain connectivity, with accumulating evidence linking migraine to altered connectivity, particularly in the insula. However, the neuropathological mechanisms underlying MRM during the menstrual cycle remain poorly understood.

Thymic characteristics in patients with autoimmune diseases: a multicentre radiological observational study.

Background: Autoimmune diseases comprise a spectrum of illnesses stemming from a common etiology: the loss of self-tolerance. The organ crucial for the establishment and maintenance of central and peripheral tolerance, namely the thymus, has rarely been explored across these diseases.

Methods: In a multicentre radiological case-control study, we characterized the thymus in 16 prevalent autoimmune diseases using chest computed tomography (CT) images from patients and age- and sex-1:1 matched healthy controls.

Aberrations in peripheral B lymphocytes and B lymphocyte subsets levels in Parkinson disease: a systematic review.

Objective: The association of B lymphocytes and B lymphocyte subsets and Parkinson's disease (PD) is increasingly acknowledged. However, there is inconsistence in the alterations of B lymphocytes or B lymphocyte subsets in peripheral blood of PD patients. To comprehensively understand its changes in PD patients,it is necessary to conduct a systematic review on this subject.

A novel intelligent grade classification architecture for Patent Foramen Ovale by Contrast Transthoracic Echocardiography based on deep learning.

Patent foramen ovale (PFO) is one of the main causes of ischemic stroke. Due to the complex characteristics of contrast transthoracic echocardiography (cTTE), PFO classification is time-consuming and laborious in clinical practice. For this reason, a variety of PFO diagnostic models have been presented based on machine learning in recent years.

Potential targets of microglia in the treatment of neurodegenerative diseases: Mechanism and therapeutic implications.

For diverse neurodegenerative disorders, microglial cells are activated. Furthermore, dysfunctional and hyperactivated microglia initiate mitochondrial autophagy, oxidative stress, and pathological protein accumulation, ending with neuroinflammation that exacerbates damage to dopaminergic neurons and contributes significantly to the pathology of neurodegenerative disorder. Microglial over-activation is closely associated with the secretion of pro-inflammatory cytokines, the phagocytosis of injured neurons, and the modulation of neurotoxic environments.

Pyroptosis the Emerging Link Between Gut Microbiota and Multiple Sclerosis.

This review elucidates the pivotal role of pyroptosis, triggered by gut microbiota, in the development of multiple sclerosis (MS), emphasizing its significance within the gut-brain axis. Our comprehensive analysis of recent literature reveals how dysbiosis in the gut microbiota of MS patients-characterized by reduced microbial diversity and shifts in bacterial populations-profoundly impacts immune regulation and the integrity of the central nervous system (CNS). Pyroptosis, an inflammatory form of programmed cell death, significantly exacerbates MS by promoting the release of inflammatory cytokines and causing substantial damage to CNS tissues.

Exogenous α-Synuclein Induces Oxidative Damage to Dopaminergic Neurons Through p-NMDAR2B/Nur77.

Alpha-synuclein (α-syn) is a major pathological marker of Parkinson's disease (PD), and its abnormal expression and aggregation lead to dopaminergic neuron degeneration, in which oxidative stress plays an important role. However, the exact molecular mechanism by which α-syn causes PD remains unclear. In this study, exogenous α-syn, also known as α-syn preformed fibrils (α-syn PFFs), was used to construct in vivo and in vitro models of PD.

Neuronal regulated cell death in aging-related neurodegenerative diseases: key pathways and therapeutic potentials.

Regulated cell death (such as apoptosis, necroptosis, pyroptosis, autophagy, cuproptosis, ferroptosis, disulfidptosis) involves complex signaling pathways and molecular effectors, and has been proven to be an important regulatory mechanism for regulating neuronal aging and death. However, excessive activation of regulated cell death may lead to the progression of aging-related diseases. This review summarizes recent advances in the understanding of seven forms of regulated cell death in age-related diseases.

A joint entity Relation Extraction method for document level Traditional Chinese Medicine texts.

Chinese medicine is a unique and complex medical system with complete and rich scientific theories. The textual data of Traditional Chinese Medicine (TCM) contains a large amount of relevant knowledge in the field of TCM, which can serve as guidance for accurate disease diagnosis as well as efficient disease prevention and treatment. Existing TCM texts are disorganized and lack a uniform standard.

Nur77 increases mitophagy and decreases aggregation of α-synuclein by modulating the p-c-Abl/p-PHB2 Y121 in α-synuclein PFF SH-SY5Y cells and mice.

Parkinson's disease (PD) is characterized by the progressive death of dopamine (DA) neurons and the pathological accumulation of α-synuclein (α-syn) fibrils. In our previous study, simulated PHB2 phosphorylation was utilized to clarify the regulatory role of c-Abl in PHB2-mediated mitophagy in PD models. In this investigation, we employed an independently patented PHB2Y121 phosphorylated antibody in the PD model to further verify that the c-Abl inhibitor STI571 can impede PHB2Y121 phosphorylation, decrease the formation of α-Syn polymers, and improve autophagic levels.

The key roles of reactive oxygen species in microglial inflammatory activation: Regulation by endogenous antioxidant system and exogenous sulfur-containing compounds.

Aberrant innate immunity in the brain has been implicated in the pathogenesis of several central nervous system (CNS) disorders, including Alzheimer's disease, Huntington's disease, Parkinson's disease, stroke, amyotrophic lateral sclerosis, and depression. Except for extraparenchymal CNS-associated macrophages, which predominantly afford protection against peripheral invading pathogens, it has been reported that microglia, a population of macrophage-like cells governing CNS immune defense in nearly all neurological diseases, are the main CNS resident immune cells. Although microglia have been recognized as the most important source of reactive oxygen species (ROS) in the CNS, ROS also may underlie microglial functions, especially M1 polarization, by modulating redox-sensitive signaling pathways.

The purpose of this study was to investigate whether idebenone could improve behavioral disorders, especially motor, learning, and memory disorders, in mouse PD models and to explore its molecular mechanism.

Autophagy-Dependent Ferroptosis-Related Signature is Closely Associated with the Prognosis and Tumor Immune Escape of Patients with Glioma.

Background: Ferroptosis is an autophagy-dependent form of cell death, sometimes called "ferritinophagy". Its related pathway has been proven to regulate the programmed death of glioma stem cells.
