Pharmacotherapeutic potential of Vitis vinifera(grape) in age-related neurological diseases / Potencial farmacoterapéutico de Vitis vinifera(uva) en enfermedades neurológicas asociadas a la edad

Age-related neurological disorders (ANDs), including neurodegenerative diseases, are complex illnesses with an increasing risk with advancing years. The central nervous system's neuropathological conditions, including oxidative stress, neuroinflammation, and protein misfolding, are what define ANDs. Due to the rise in age-dependent prevalence, efforts have been made to combat ANDs. Vitis viniferahas a long history of usageto treat a variety of illness symptoms. Because multiple ligand sites may be targeted, Vitis viniferacomponents can be employed to treat ANDs. This is demonstrated by the link between the structure and action of these compounds. This review demonstrates that Vitis viniferaand its constituents, including flavonoids, phenolic compounds, stilbenoidsandaromatic acids, are effective at reducing the neurological symptoms and pathological conditions of ANDs. This is done by acting as an antioxidant and anti-inflammatory. The active Vitis vinifera ingredients have therapeutic effects on ANDs, as this review explains.

Las enfermedades neurológicas asociadas a la edad (AND, por su sigla en inglés) incluyendo las enfermedades neurodegenerativas, son enfermedades complejas con un riesgo creciente con la edad. Las condiciones neuropatológicas del sistema nervioso central, que incluyen el estrés oxidativo, la neuro inflamación, y el plegado erróneo de proteínas, son lo que define las AND. Debido al aumento en la prevalencia dependiente de la edad, se han hecho esfuerzos para combatir las AND. Vitis vinifera tiene una larga historia de uso para el tratamiento de síntomas. Puesto que puede hacer objetivo a muchos sitios ligando, los componentes de Vitis viniferase pueden utilizar para tratar AND. Esto se demuestra por el vínculo entre la estructura y la acción de estos compuestos. Esta revisión demuestra que la Vitis viniferay sus constituyentes, incluídos los flavonoides, componentes fenólicos, estilbenoides, y ácidos aromáticos, son efectivos para reducir los síntomas neurológicos y las condiciones patológicas de AND. Esto se produce por su acción como antioxidante y antiinflamatorio. Los ingredientes activos de Vitis vinifera tienen efectos terapéuticos en AND, y esta revisión lo explica.

Mechanism of Traditional Chinese Medicine in Treatment of Neurodegenerative Diseases by Regulating Polarization Balance of Microglia： A Review / 中国实验方剂学杂志

Neuroinflammation is a common pathological feature of neurodegenerative diseases （NDs）. Microglia （MG）， a resident macrophage in the brain with a unique developmental origin， is the core driver of neuroinflammation. It can participate in the occurrence and development of NDs through different polarization states and play a key role in regulating neurogenesis and synapse shaping and maintaining homeostasis. MG can be divided into M1 pro-inflammatory phenotype and M2 anti-inflammatory phenotype according to its function. The inflammatory mediators released by the M1 phenotype can lead to nerve degeneration and myelin sheath damage， while the activation of the M2 phenotype is required to inhibit the inflammatory response and promote tissue repair. With the advantages of multi-pathway， multi-target， and bidirectional regulation， traditional Chinese medicine can regulate the polarization balance of MG and has dual effects on NDs such as Alzheimer's disease， Parkinson's disease， and multiple sclerosis. The active components of traditional Chinese medicine and its compound can inhibit the activation of MG by regulating phosphatidylinositol-3-kinases/protein kinase B（PI3K/Akt）， NOD-like receptor thermal protein domain associated protein 3（NLRP3）， signal transducer and activator of transcription factor1（STAT1）， nuclear transcription factor kappa B（NF-κB）， and other pathways， promote the polarization of M1 phenotype to M2 phenotype， reduce the expression of interleukin（IL）-6， tumor necrosis factor-α（TNF-α）， and other pro-inflammatory factors， and increase the secretion of IL-10， arginase-1（Arg-1）， and other anti-inflammatory factors. It can also reduce β-amyloid deposition and tau protein expression in Alzheimer's disease， alleviate dopaminergic neuronal damage in Parkinson's disease， and relieve demyelination， inflammatory cell infiltration， and related clinical symptoms of multiple sclerosis. The bidirectional regulation of the M1/M2 polarization balance of MG by traditional Chinese medicine is a potential strategy for the treatment of NDs. This paper focused on the targets of the regulation of MG polarization balance by traditional Chinese medicine monomer and its compound in the treatment of NDs， so as to further study and summarize the existing research results and provide ideas and basis for the future treatment of NDs.

Therapeutic potential of NADH: in neurodegenerative diseases characterizde by mitochondrial dysfunction / 临床耳鼻咽喉头颈外科杂志

Nicotinamide adenine dinucleotide（NADH） in its reduced form of is a key coenzyme in redox reactions, essential for maintaining energy homeostasis.NADH and its oxidized counterpart, NAD+, form a redox couple that regulates various biological processes, including calcium homeostasis, synaptic plasticity, anti-apoptosis, and gene expression. The reduction of NAD+/NADH levels is closely linked to mitochondrial dysfunction, which plays a pivotal role in the cascade of various neurodegenerative disorders, including Parkinson's disease and Alzheimer's disease.Auditory neuropathy（AN） is recognized as a clinical biomarker in neurodegenerative disorders. Furthermore, mitochondrial dysfunction has been identified in patients with mutations in genes like OPA1and AIFM1. However, effective treatments for these conditions are still lacking. Increasing evidence suggests that administratering NAD+ or its precursors endogenously may potentially prevent and slow disease progression by enhancing DNA repair and improving mitochondrial function. Therefore, this review concentrates on the metabolic pathways of NAD+/NADH production and their biological functions, and delves into the therapeutic potential and mechanisms of NADH in treating AN.

Decoding the Cellular Trafficking of Prion-like Proteins in Neurodegenerative Diseases / 神经科学通报·英文版

The accumulation and spread of prion-like proteins is a key feature of neurodegenerative diseases (NDs) such as Alzheimer's disease, Parkinson's disease, or Amyotrophic Lateral Sclerosis. In a process known as 'seeding', prion-like proteins such as amyloid beta, microtubule-associated protein tau, α-synuclein, silence superoxide dismutase 1, or transactive response DNA-binding protein 43 kDa, propagate their misfolded conformations by transforming their respective soluble monomers into fibrils. Cellular and molecular evidence of prion-like propagation in NDs, the clinical relevance of their 'seeding' capacities, and their levels of contribution towards disease progression have been intensively studied over recent years. This review unpacks the cyclic prion-like propagation in cells including factors of aggregate internalization, endo-lysosomal leaking, aggregate degradation, and secretion. Debates on the importance of the role of prion-like protein aggregates in NDs, whether causal or consequent, are also discussed. Applications lead to a greater understanding of ND pathogenesis and increased potential for therapeutic strategies.

Choreiform movements and basal ganglia calcification as a presentation of Fahr's disease

Basal ganglia calcifications may be a radiological finding in approximately 20% of the general population. When they are associated with neuropsychiatric and motor symptoms in an idiopathic form, they are known as Fahr's disease. They are termed "Fahr's syndrome" when they are secondary to an identifiable and potentially treatable cause. In this report, we present the clinical case of a 69-year-old woman with the onset of subacute chorea, with no other associated symptoms, in whom extensive basal ganglia calcifications were found on neuroimaging, due to which metabolic disorders were subsequently ruled out. The objective is to contribute to the characterization of the potential motor manifestations which would give rise to clinical suspicion. Due to its low incidence and the little information on this condition in the region, we want to encourage documentation of other cases and the process for ruling out other differential diagnoses, in order to obtain more information on its actual epidemiology and signs and symptoms in Colombia.

Uso de cannabidiol para el control de síntomas refractarios en síndromes convulsivos y enfermedades neurodegenerativas / Use of cannabidiol for the control of refractory symptoms in convulsive syndromes and neurodegenerative diseases

Como parte de las terapias alternativas para el control de síntomas refractarios en enfermedades avanzadas destaca el uso de cannabidiol. Este se ha estudiado en patologías como enfermedad de Alzheimer, Parkinson y trastornos convulsivos. Los síndromes convulsivos están presentes en todos los grupos etarios. Dentro de este, la epilepsia es refractaria hasta en un 40 % de los pacientes, quienes han demostrado disminución en la frecuencia de convulsiones con el uso concomitante de cannabidiol y antiepilépticos convencionales, con efectos secundarios leves, como diarrea y somnolencia. Con el objetivo de determinar el uso del cannabidiol para el control de síntomas neurológicos refractarios en pacientes con síndromes convulsivos y enfermedades neurodegenerativas, se realizó una búsqueda bibliográfica en Pubmed, Scopus y Embase. Se incluyeron metaanálisis, artículos originales, revisiones sistemáticas y bibliográficas, y documentos de la Organización Panamericana de la Salud, publicados entre 2017 y 2022. Los efectos del cannabidiol lo convierten en una alternativa, adicional a la terapéutica convencional, para el control de síntomas en trastornos neurológicos, disminuyendo de forma sostenida el número total de episodios con un perfil de seguridad aceptable. Existe limitada información respecto al uso de cannabidiol en enfermedades neurodegenerativas, por lo que no se ha evidenciado su efectividad

As part of the alternative therapies for the control of refractory symptoms in advanced diseases, the use of cannabidiol stands out. It has been studied in pathologies such as Alzheimer's disease, Parkinson's disease, and convulsive disorders. Convulsive syndromes are present in all age groups. Within this group, epilepsy is refractory in up to 40 % of patients, who have shown a decrease in the frequency of seizures with the concomitant use of cannabidiol and conventional antiepileptics, with mild side effects such as diarrhea and drowsiness. To determine the use of cannabidiol for the control of refractory neurological symptoms in patients with seizure syndromes and neurodegenerative diseases, a literature search was performed in PubMed, Scopus, and Embase. Meta-analyses, original articles, systematic and literature reviews, and documents from the Pan American Health Organization, published between 2017 and 2022, were included. The effects of cannabidiol make it an alternative, in addition to conventional therapeutics, for symptom control in neurological disorders, sustainably decreasing the total number of episodes with an acceptable safety profile. There is limited information regarding the use of cannabidiol in neurodegenerative diseases, the reason its effectiveness has not been demonstrated.

Clinical Features and Mutation Analysis of Gordon Holmes Syndrome Associated with RNF216 Gene Mutation and a Literature Review / 罕见病研究

  Objective  To summarize the clinical characteristics and RNF216 gene mutation of a patient with Gordon Holmes syndrome (GHS), and to improve the understanding of the genetic and clinica characteristics of this disease through literature review.  Methods  We collected the clinical data of the patient with GHS, extracted the DNA from 2 mL peripheral venous blood of the patient and his parents for whole exome gene detection, and then we analyzed the clinical and genetic characteristics of all previously reported patients with RNF216 gene mutation.  Results  The young male patient was short in stature at sixyearsold and was diagnosed growth hormone deficiency.He had no secondary sexual characteristics by the age of 15 and was diagnosed hypogonadal hypogonadism.After the age of 22, he gradually developed abnormal gait and had progressive decline in speech, motor, and cognitive functions.Whole exome sequencing revealed a homozygous, nonsense mutation c.1549C>T (p.R517*) in the RNF216 gene.His parents were consanguineous and were heterozygous carriers of the mutations with phenotypic normality.Combined with literature review and this case report results showed that a total of 21 patients of the disease in the world and among them 15 had pathogenic variants of RNF216 gene mutation.7 of the 15 had truncated mutations, 5 had missense mutations, and 1 synonym mutation, 1 splice mutation, and 1 deletion mutation respectively.RNF216 gene mutation can be seen in neurodegenerative diseases with multiple overlapping symptoms of GHS, Huntington-like disease, and 4H syndrome.The main clinical manifestations are hypogonadotropic hypogonadism and early-onset progressive neurological dysfunction in adolescence or early adulthood.The median age of onset of neurological symptoms is 28 years old, featuring cerebellar ataxia, dysarthria, and cognitive impairment, as well as imaging manifestations of extensive white matter lesions and cerebellar atrophy.  Conclusions  The mutation of RNF216 gene can cause GHS.Genetic testing is helpful to the diagnosis and treatment of rare diseases.

Progress of Research on Relationship of Circadian Rhythm Disorder and Gut Microbiota Involved in Neurodegenerative Diseases / 胃肠病学

With the increase in global life expectancy, the incidence of neurodegenerative diseases is increasing year by year. Studies have confirmed that patients with different types of neurodegenerative diseases have circadian rhythm disorder and gut microbiota dysregulation. The occurrence of neurodegenerative diseases and circadian rhythm disorder are mutually causal, and in this causal relationship, gut microbiota may play an important role. Gut microbiota affects the communication between gut and brain through "microbiota ⁃ gut ⁃ brain axis", and can affect neural development. Gut microbiota dysregulation can increase the risk of neurodegenerative diseases. At the same time, the diurnal fluctuation of gut microbiota themselves is also regulated by the host biological clock. This article reviewed the progress of research on relationship of circadian rhythm disorder and gut microbiota involved in neurodegenerative diseases.

Oxidative stress, the blood-brain barrier and neurodegenerative diseases: The critical beneficial role of dietary antioxidants

In recent years, growing awareness of the role of oxidative stress in brain health has prompted antioxidants, especially dietary antioxidants, to receive growing attention as possible treatments strategies for patients with neurodegenerative diseases (NDs). The most widely studied dietary antioxidants include active substances such as vitamins, carotenoids, flavonoids and polyphenols. Dietary antioxidants are found in usually consumed foods such as fresh fruits, vegetables, nuts and oils and are gaining popularity due to recently growing awareness of their potential for preventive and protective agents against NDs, as well as their abundant natural sources, generally non-toxic nature, and ease of long-term consumption. This review article examines the role of oxidative stress in the development of NDs, explores the 'two-sidedness' of the blood-brain barrier (BBB) as a protective barrier to the nervous system and an impeding barrier to the use of antioxidants as drug medicinal products and/or dietary antioxidants supplements for prevention and therapy and reviews the BBB permeability of common dietary antioxidant suplements and their potential efficacy in the prevention and treatment of NDs. Finally, current challenges and future directions for the prevention and treatment of NDs using dietary antioxidants are discussed, and useful information on the prevention and treatment of NDs is provided.

Nanopolyphenol rejuvenates microglial surveillance of multiple misfolded proteins through metabolic reprogramming

Microglial surveillance plays an essential role in clearing misfolded proteins such as amyloid-beta, tau, and α-synuclein aggregates in neurodegenerative diseases. However, due to the complex structure and ambiguous pathogenic species of the misfolded proteins, a universal approach to remove the misfolded proteins remains unavailable. Here, we found that a polyphenol, α-mangostin, reprogrammed metabolism in the disease-associated microglia through shifting glycolysis to oxidative phosphorylation, which holistically rejuvenated microglial surveillance capacity to enhance microglial phagocytosis and autophagy-mediated degradation of multiple misfolded proteins. Nanoformulation of α-mangostin efficiently delivered α-mangostin to microglia, relieved the reactive status and rejuvenated the misfolded-proteins clearance capacity of microglia, which thus impressively relieved the neuropathological changes in both Alzheimer's disease and Parkinson's disease model mice. These findings provide direct evidences for the concept of rejuvenating microglial surveillance of multiple misfolded proteins through metabolic reprogramming, and demonstrate nanoformulated α-mangostin as a potential and universal therapy against neurodegenerative diseases.

Progress in study on the final executor of necroptosis MLKL and its inhibitors / 中南大学学报(医学版)

Necroptosis is one of the regulated cell death, which involves receptor interacting protein kinase (RIPK) 1/RIPK3/mixed lineage kinase domain like protein (MLKL) signaling pathway. Among them, MLKL is the final execution of necroptosis. The formation of RIPK1/RIPK3/MLKL necrosome induces the phosphorylated MLKL, and the activated MLKL penetrates into the membrane bilayer to form membrane pores, which damages the integrity of the membrane and leads to cell death. In addition to participating in necroptosis, MLKL is also closely related to other cell death, such as NETosis, pyroptosis, and autophagy. Therefore, MLKL is involved in the pathological processes of various diseases related to abnormal cell death pathways (such as cardiovascular diseases, neurodegenerative diseases and cancer), and may be a therapeutic target of multiple diseases. Understanding the role of MLKL in different cell death can lay a foundation for seeking various MLKL-related disease targets, and also guide the development and application of MLKL inhibitors.

Polymeric nanocarriers for nose-to-brain drug delivery in neurodegenerative diseases and neurodevelopmental disorders

Neurodegenerative diseases are progressive conditions that affect the neurons of the central nervous system (CNS) and result in their damage and death. Neurodevelopmental disorders include intellectual disability, autism spectrum disorder, and attention-deficit/hyperactivity disorder and stem from the disruption of essential neurodevelopmental processes. The treatment of neurodegenerative and neurodevelopmental conditions, together affecting ∼120 million people worldwide, is challenged by the blood-brain barrier (BBB) and the blood-cerebrospinal fluid barrier that prevent the crossing of drugs from the systemic circulation into the CNS. The nose-to-brain pathway that bypasses the BBB and increases the brain bioavailability of intranasally administered drugs is promising to improve the treatment of CNS conditions. This pathway is more efficient for nanoparticles than for solutions, hence, the research on intranasal nano-drug delivery systems has grown exponentially over the last decade. Polymeric nanoparticles have become key players in the field owing to the high design and synthetic flexibility. This review describes the challenges faced for the treatment of neurodegenerative and neurodevelopmental conditions, the molecular and cellular features of the nasal mucosa and the contribution of intranasal nano-drug delivery to overcome them. Then, a comprehensive overview of polymeric nanocarriers investigated to increase drug bioavailability in the brain is introduced.

Neuroprotective potential of cannabidiol: Molecular mechanisms and clinical implications / 中西医结合学报

Cannabidiol (CBD), a nonpsychotropic phytocannabinoid that was once largely disregarded, is currently the subject of significant medicinal study. CBD is found in Cannabis sativa, and has a myriad of neuropharmacological impacts on the central nervous system, including the capacity to reduce neuroinflammation, protein misfolding and oxidative stress. On the other hand, it is well established that CBD generates its biological effects without exerting a large amount of intrinsic activity upon cannabinoid receptors. Because of this, CBD does not produce undesirable psychotropic effects that are typical of marijuana derivatives. Nonetheless, CBD displays the exceptional potential to become a supplementary medicine in various neurological diseases. Currently, many clinical trials are being conducted to investigate this possibility. This review focuses on the therapeutic effects of CBD in managing neurological disorders like Alzheimer's disease, Parkinson's disease and epilepsy. Overall, this review aims to build a stronger understanding of CBD and provide guidance for future fundamental scientific and clinical investigations, opening a new therapeutic window for neuroprotection.

Research progress on traditional Chinese medicine in treatment of neurodegenerative diseases by delaying neurovascular unit aging / 中国中药杂志

Neurodegenerative diseases are a collective term for a large group of diseases caused by degenerative changes in nerve cells. Aging is the main risk factor for neurodegenerative diseases. The neurovascular unit(NVU) is the smallest functional unit of the brain, which regulates brain blood flow and maintains brain homeostasis. Accelerated aging of NVU cells directly impairs NVU function and leads to the occurrence of various neurodegenerative diseases. The intrinsic mechanisms of NVU cell aging are complex and involve oxidative stress damage, loss of protein homeostasis, DNA damage, mitochondrial dysfunction, immune inflammatory response, and impaired cellular autophagy. In recent years, studies have found that traditional Chinese medicine(TCM) can inhibit NVU aging through multiple pathways and targets, exerting a brain-protective effect. Therefore, this article aimed to provide a theoretical basis for further research on TCM inhibition of NVU cell aging and references for new drug development and clinical applications by reviewing its mechanisms of anti-aging, such as regulating relevant proteins, improving mitochondrial dysfunction, reducing DNA damage, lowering inflammatory response, antioxidant stress, and modulating cellular autophagy.

Research progress on treatment strategies for related diseases based on Parthanatos / 中国生物制品学杂志

@#Parthanatos is a form of programmed cell death,which is also known as poly(ADP-ribose)polymerase 1(PARP1)-mediated apoptosis-inducing factor(AIF)and macrophage migration inhibitory factor(MIF)-dependent cell death according to its molecular mechanism. Parthanatos is the main cause of a variety of neurodegenerative diseases,such as Parkinson's disease(PD),Alzheimer's disease(AD),motor neuron disease,and is also involved in the pathogenesis of some tumors,such as lung cancer and breast cancer. Therefore,a thorough understanding of the molecular mechanism of Parthanatos is crucial for the therapeutic strategies of related diseases. In recent years,studies have found that effective regulation of the occurrence of Parthanatos by regulating the key proteins PARP1,AIF and MIF is expected to become a therapeutic target for many diseases. Based on the specific molecular mechanism of Parthanatos,this paper reviewed the research progress of therapeutic strategies for related diseases from the aspects of inhibiting and promoting Parthanatos.

Enterovirus infection and its relationship with neurodegenerative diseases

Neurodegenerative diseases (NDs) are increasingly common, especially in populations with higher life expectancies. They are associated mainly with protein metabolism and structure changes, leading to neuronal cell death. Viral infections affect these cellular processes and may be involved in the etiology of several neurological illnesses, particularly NDs. Enteroviruses (EVs) frequently infect the central nervous system (CNS), causing neurological disease. Inflammation, disruption of the host autophagy machinery, and deregulation and accumulation/misfolding of proteins are the main alterations observed after infection by an EV. In this perspective, we discuss the most recent findings on the subject, examining the possible role of EVs in the development of NDs, and shedding light on the putative role played by these viruses in developing NDs.
