Spinal cord injury (SCI)-induced neuroinflammation and oxidative stress (OS) are crucial events causing neurological dysfunction. Aconitate decarboxylase 1 (ACOD1) its metabolite itaconate (Ita) inhibit inflammation OS by promoting alkylation of Keap1 to induce Nrf2 expression; however, it is unclear whether there another pathway regulating their effects in inflammation-activated microglia after SCI. Adult male C57BL/6 ACOD1-/- mice wild-type (WT) littermates were subjected a moderate thoracic spinal contusion. The degree the injured assessed using qPCR, western blot, flow cytometry, immunofluorescence, trans-well assay. We then employed immunoprecipitation-western chromatin immunoprecipitation (ChIP)-PCR, dual-luciferase assay, immunofluorescence-confocal imaging examine molecular mechanisms ACOD1. Finally, locomotor function was evaluated with Basso Mouse Scale footprint Both vitro vivo, transcriptional blockage ACOD1 exhibited more severe levels OS, which expression p62/Keap1/Nrf2 down-regulated. Furthermore, silencing exacerbated dysfunction SCI mice. Administration exogenous Ita or 4-octyl reduced p62 phosphorylation. Besides, capable interacting phosphorylated enhance activation, turn further promoted transcription Here, we identified an unreported ACOD1-p62-Nrf2-ACOD1 feedback loop exerting anti-inflammatory anti-OS inflammatory microglia, demonstrated neuroprotective role SCI, different from that endogenous Ita. present study extends functions uncovers marked property differences between attenuated injury. ACOD1, not itaconate, interacted p-p62 facilitate nuclear translocation. microglia.

Resveratrol (3,4',5-trihy- droxystilbene), a natural phytoalexin polyphenol, exhibits anti-oxidant, anti-inflammatory, and anti-carcinogenic properties. This is well-absorbed rapidly extensively metabolized in the body. Inflammation an adaptive response, which could be triggered by various danger signals, such as invasion microorganisms or tissue injury. In this review, anti-inflammatory activity mechanism of resveratrol modulates inflammatory response are examined. Multiple experimental studies that illustrate regulatory mechanisms immunomodulatory function both vivo vitro. The data acquired from those discussed.

Natural products derived from plants, as well their bioactive compounds, have been extensively studied in recent years for therapeutic potential a variety of neurodegenerative diseases (NDs), including Alzheimer’s (AD), Huntington’s (HD), and Parkinson’s (PD) disease. These are characterized by progressive dysfunction loss neuronal structure function. There has little progress designing efficient treatments, despite impressive breakthroughs our understanding NDs. In the prevention therapy NDs, use natural may provide great opportunities; however, many clinical issues emerged regarding use, primarily based on lack scientific support or proof effectiveness patient safety. Since neurodegeneration is associated with myriad pathological processes, targeting multi-mechanisms action neuroprotection approaches that include preventing cell death restoring function damaged neurons should be employed. treatment AD PD, neuroprotective agents.

Nitric oxide (NO) plays several key roles in the functionality of an organism, and it is usually released numerous organs tissues. There are mainly three isoforms enzyme that produce NO starting from metabolism arginine, namely endothelial nitric synthase (eNOS), inducible (iNOS), neuronal (nNOS). The expression activity these depends on activation/deactivation different signaling pathways at intracellular level following physiological pathological stimuli. Compounds natural origin such as polyphenols, which obtainable through diet, have been widely studied recent years vivo vitro investigations for their ability to induce or inhibit release, depending tissue. In this review, we aim disclose scientific evidence relating main dietary polyphenols modulation involved and/or NOS isoforms.

Alzheimer's disease (AD) is a complex neurodegenerative disorder characterized by progressive cognitive decline, memory loss, and behavioral changes. It poses significant global health challenge. AD associated with the accumulation of amyloid-β (Aβ) plaques neurofibrillary tangles (NFTs) in brain, along chronic inflammation, dysfunctional neurons, synapse loss. While prevalence continues to rise, current FDA-approved drugs offer only limited effectiveness. Emerging evidence suggests that obesity, insulin resistance (IR), type 2 diabetes mellitus (T2DM) are also implicated pathogenesis, epidemiological studies animal models confirming impact IR on Aβ accumulation, high-fat diets exacerbating accumulation. Since neuroinflammation activated involves nuclear factor kappa-light-chain-enhancer B cell (NF-κB) pathway, inhibition NF-κB NLRP3 inflammasome activation potential therapeutic strategies AD. Bioactive compounds, including polyphenols (resveratrol, epigallocatechin-3-gallate, curcumin, quercetin), omega-3 polyunsaturated fatty acids, show promising results clinical trials for reducing levels, improving cognition modulating signaling pathways This review explores interplay between IR, pathology, emphasizing dietary compounds their role oxidative stress, as viable prevention treatment. By integrating findings, observational studies, trials, this aims provide comprehensive understating how metabolic dysfunctions bioactive influence progression.
