Parkinson's disease (PD) is a neurodegenerative disorder involving motor symptoms caused by loss of dopaminergic neurons in the substantia nigra region brain. Epidemiological evidence suggests that anthocyanin (ANC) intake associated with low risk PD. Previously, we reported extracts enriched ANC and proanthocyanidins (PAC) suppressed neuron death elicited PD-related toxin rotenone primary midbrain culture model. Here, characterized botanical mixed profile polyphenols, as well set purified polyphenolic standards, terms their ability to mitigate cell cultures exposed another toxicant, paraquat (PQ), examined underlying neuroprotective mechanisms. Extracts prepared from blueberries, black currants, grape seeds, skin, mulberries, plums, several ANC, were found rescue PQ-treated cultures. Comparison subset ANC-rich for neurotoxicity PQ versus revealed hibiscus or plum extract was only PQ, respectively. Several compounds protect against increased activity antioxidant transcription factor Nrf2 cultured astrocytes, PQ-induced attenuated Nrf2-expressing In other studies, hibiscus, purple basil (but not plums) rescued defects O2 consumption neuronal cells treated rotenone. Collectively, these findings suggest certain combinations PAC, stilbenes, polyphenols could potentially slow neurodegeneration brains individuals activating cellular mechanisms and/or alleviating mitochondrial dysfunction.

Neurodegenerative disorders (NDs) including Alzheimer's disease, Parkinson's amyotrophic lateral sclerosis, Huntington's and multiple sclerosis have various disease-specific causal factors pathological features. A very common characteristic of NDs is oxidative stress (OS), which takes place due to the elevated generation reactive oxygen species during progression NDs. Furthermore, condition an increased level protein aggregates can further lead chronic inflammation because microglial activation. Carotenoids (CTs) are naturally occurring pigments that play a significant role in averting brain disorders.

Polyphenols (PPs) are a large group of phytochemicals containing phenolic rings with two or more hydroxyl groups. They possess powerful antioxidant properties, multiple therapeutic effects, and possible health benefits in vivo vitro, as well reported clinical studies. Considering their free-radical scavenging anti-inflammatory these substances can be used to treat different kinds conditions associated metabolic disorders. Many symptoms syndrome (MtS), including obesity, dyslipidemia, atherosclerosis, elevated blood sugar, accelerating aging, liver intoxication, hypertension, cancer neurodegenerative disorders, substantially relieved by dietary PPs. The present study explores the bioprotective properties underlying mechanisms A detailed understanding natural compounds will open up new opportunities for producing unique PP-rich medicinal plans, ultimately affirming benefits.

Neurodegenerative diseases are known for their wide range of harmful conditions related to progressive cell damage, nervous system connections and neuronal death. These pathologies promote the loss essential motor cognitive functions, such as mobility, learning sensation. Neurodegeneration affects millions people worldwide, no integral cure has been created yet. Here, bioactive compounds have proven exert numerous beneficial effects due remarkable bioactivity, so they could be considered great options development new neuroprotective strategies. Phenolic bioactives reported found in edible part plants; however, over last years, a large amount research focused on phenolic richness that plant by-products possess, which sometimes even exceeds content pulp. Thus, possible application an emergent technique also optimal strategy revalorize these agricultural residues (those originated from processing). This review aims summarize main triggers neurodegeneration, revise state art extracts role avoiding neurodegeneration discuss how effects. For this purpose, diverse search studies conducted, gathering number papers where were used strong sources properties. Finally, although lack investigation is quite greatly limits use compounds, phenolics remain attractive into multifactorial anti-neurodegenerative nutraceuticals.

Abstract Plant‐derived exosomes (PEs) possess an array of therapeutic properties, including antitumor, antiviral, and anti‐inflammatory capabilities. They are also implicated in defensive responses to pathogenic attacks. Spinal cord injuries (SCIs) regeneration represents a global medical challenge, with appropriate research concentration on three pivotal domains: neural promotion, inflammation inhibition, innovation application regenerative scaffolds. Unfortunately, the utilization PE SCI therapy remains unexplored. Herein, we isolated from traditional Chinese medicinal herb, Lycium barbarum L. discovered their inflammatory inhibition neuronal differentiation promotion Compared derived ectomesenchymal stem cells (EMSCs), demonstrated substantial enhancement differentiation. We encapsulated isoliquiritigenin (ISL)‐loaded plant‐derived (ISL@PE) within 3D‐printed bionic scaffold. The intricate construct modulated response following SCI, facilitating restoration damaged axons culminating ameliorated neurological function. This pioneering investigation proposes novel potential route for insoluble drug delivery via plant exosomes, as well repair. institutional animal care use committee number is UJS‐IACUC‐2020121602.

Glutathione (GSH) is the most abundant intrinsic antioxidant in central nervous system, and its substrate cysteine readily becomes oxidized dimeric cystine. Since neurons lack a cystine transport neuronal GSH synthesis depends on uptake via cystine/glutamate exchange transporter (xCT), synthesis, release in/from surrounding astrocytes. Transcription factor nuclear erythroid 2-related 2 (Nrf2), detoxifying master transcription factor, expressed mainly astrocytes activates gene expression of various phase II drug-metabolizing enzymes or antioxidants including GSH-related molecules metallothionein by binding to response element (ARE) these genes. Accumulating evidence has shown involvement dysfunction antioxidative related pathogenesis Parkinson's disease (PD) parkinsonian models. Furthermore, we found several agents targeting that protect nigrostriatal dopaminergic loss PD In this article, neuroprotective effects supplementation enhancement pathology are reviewed, along with introducing new experimental findings, especially xCT-GSH synthetic system Nrf2-ARE pathway

A central feature of a variety related neurological disorders, including amyotrophic lateral sclerosis (ALS), is the deposition misfolded protein aggregates in key regions human brain. Hence, targeting aggregation-prone SOD1 with small molecules can be used to design strategies inhibit its aggregation. Based on molecular docking and dynamics (MD) simulation, this study suggested that plant flavonoids act as potent anti-amyloidogenic polyphenol against Initial screening identified Rosmarinic acid Salvianolic promising drug leads effectively pathogenic behaviour. Our results showed reduces β-sheet content increases structural stability, hydrophobicity, flexibility, significantly lost hydrogen bonds mutant compared other compounds. Besides, we revealed changes free energy landscape (FEL) WT-SOD1 states (unbound/bound) differentiate We deduced above-mentioned deviation behaviour D124 V mutant.
