Neurodegenerative disorders (NDs) are a cluster of progressive, severe, and disabling that affect millions people worldwide on the surge. These characterized by gradual loss selectively vulnerable group neurons. Due to complex pathophysiological mechanisms behind neurodegeneration despite enormous efforts understanding occurrence progression NDs, there is still lack an effective treatment for such diseases. Therefore, development new therapeutic strategy NDs unmet clinical need. Various natural compounds extracted from medicinal plants or fruits have shown promising activities in treating different types targeting multiple signaling pathways. Among entities, flavonoids incited rise public scientific interest recent years because their purported health-promoting effects. Dietary supplementation has been mitigate severity as Parkinson's disease (PD), Alzheimer's (AD), dementia antioxidant Naringenin citrus flavonoid known possess numerous biological like antioxidant, anti-proliferative, anti-inflammatory activities. naringenin emerged potential agent exerts preventive curative effects several neurological disorders.

The elderly population is growing worldwide, with important health and socioeconomic implications. Clinical experimental studies on aging have uncovered numerous changes in the brain, such as decreased neurogenesis, increased synaptic defects, greater metabolic stress, enhanced inflammation. These are associated cognitive decline neurobehavioral deficits. Although not a disease, it significant risk factor for functional worsening, affective impairment, disease exaggeration, dementia, general susceptibility. Conversely, life events related to mental stress trauma can also lead accelerated age-associated disorders dementia. Here, we review human mice rats, those modeling neurodegenerative diseases, that helped elucidate (1) dynamics mechanisms underlying biological pathological of main projecting systems brain (glutamatergic, cholinergic, dopaminergic) (2) effect defective glutamatergic, dopaminergic projection disabilities disorders, Alzheimer’s Parkinson’s diseases. Detailed knowledge age-related diseases be an element development effective ways treatment. In this context, briefly analyze which adverse glutaminergic could targeted by therapeutic strategies developed result our better understanding these damaging mechanisms.

Major depressive disorder is a debilitating affecting millions of people each year. Brain-derived neurotrophic factor (BDNF) and inflammation are two prominent biologic risk factors in the pathogenesis depression that have received considerable attention. Many clinical animal studies highlighted associations between low levels BDNF or high inflammatory markers development behavioral symptoms depression. However, less known about potential interaction inflammation, particularly within central nervous system. Emerging evidence suggests there bidirectional regulation these with important implications for anti-depressant response. Elevated mediators been shown to reduce expression BDNF, may play an negative regulatory role on brain. Understanding this more fully context neuropsychiatric disease both developing fuller understanding biological identifying novel therapeutic opportunities. Here we review particular focus pathogenic their interaction.

Mitochondria are associated with various cellular activities critical to homeostasis, particularly in the nervous system. The plastic architecture of mitochondrial network and its dynamic structure play crucial roles ensuring that varying energetic demands rapidly met maintain neuronal axonal energy homeostasis. Recent evidence associates aging neurodegeneration anomalous metabolism as age‐dependent alterations now believed occur prior neurodegeneration. brain has a high demand, which makes it sensitive dysfunction. Distinct events causing oxidative stress or disruption homeostasis can trigger neuropathology. This review explores bioenergetic hypothesis for neurodegenerative pathomechanisms, discussing factors leading age‐related hypometabolism contribution cognitive decline. research on healthy system cells, response stress, how is affected by pathology, well current contributions novel therapeutic approaches will be highlighted.

It has been reported that disordered Cu metabolism is associated with several neurodegenerative diseases, including Alzheimer's disease (AD) and Parkinson's (PD). However, the underlying mechanism still unclear. In this study, 4-week-old male mice were exposed to by free-drinking water for three months. Then, effects of on cognitive functions in tested Morris maze tests, potential mechanisms investigated ELISA, immunochemistry, TUNEL, Western blot tests. was found exacerbates learning memory impairment, leads Cu-overload brain urine mice. The results showed induces neuronal degeneration oxidative damage, promotes expression apoptosis-related protein Bax, cuproptosis-related proteins FDX1 DLAT proteotoxic stress marker HSP70, decreases Fe-S cluster proteins. addition, affects pre-synaptic post-synaptic regulatory through inhibiting PSD-95 SYP. also suppresses phosphorylation levels CREB BDNF TrkB mouse hippocampus. conclusion, might mediate cuproptosis, damage synaptic plasticity inhibit CREB/BDNF pathway cause dysfunction

Abstract Despite an ever-growing prevalence and increasing economic burden of Alzheimer’s disease (AD) Parkinson’s (PD), recent advances in drug development have only resulted minimally effective treatment. In AD, along with amyloid tau phosphorylation, there is associated increase inflammation/glial activation, a decrease synaptic function, astrocyte state insulin resistance. PD, α-synuclein accumulation, inflammation, dysfunction, dopaminergic neuronal loss, some data to suggest Therapeutic strategies for neurodegenerative disorders commonly targeted individual pathological processes. An treatment might require either utilization multiple drugs which target the processes underlie or use single agent could influence Insulin incretins are compounds effects on Preclinical studies demonstrated that GLP-1 receptor agonists reduce neuroinflammation, deposition, improve memory formation. Incretin mimetics may act through restoration signaling pathways, inducing further neuroprotective effects. Currently, phase 2 3 trials underway AD PD populations.

Neurodegenerative diseases (NDDs) are a class of neurological disorders marked by the progressive loss neurons that afflict millions people worldwide. These illnesses affect brain connection, impairing memory, cognition, behavior, sensory perception, and motor function. Alzheimer's, Parkinson's, Huntington's examples common NDDs, which frequently include buildup misfolded proteins. Cognitive-behavioral impairments early markers neurodevelopmental disorders, emphasizing importance detection intervention. Neurotrophins such as brain-derived neurotrophic factor (BDNF) critical for neuron survival synaptic plasticity, is required learning memory. NDDs have been associated with decreased BDNF levels. Physical exercise, non-pharmacological intervention, benefits health increasing levels, lowering cognitive deficits, slowing degradation. Exercise advantages increased well-being, reduced depression, improved skills, neuroprotection amyloid accumulation, oxidative stress, neuroinflammation. This study examines effects physical exercise on cognitive-behavioral deficits levels in limbic system impacted neurodegeneration. The findings highlight necessity including into NDD treatment to improve structure, function, total As research advances, becoming increasingly acknowledged an important technique treating decline neurodegenerative disorders.

The past few years have witnessed an increasing understanding structure function TrkB, including its transmembrane domain (TMD). interacts with membrane cholesterol, which bidirectionally regulates signaling. Additionally, has recently been recognized as binding target antidepressant drugs. A variety different antidepressants, typical rapid-acting well psychedelic compounds, act allosteric potentiators BDNF signaling through TrkB. This suggests that common compounds.
