Naringenin, a Food Bioactive Compound, Reduces Oncostatin M Through Blockade of PI3K/Akt/NF-κB Signal Pathway in Neutrophil-like Differentiated HL-60 Cells.

Oncostatin M (OSM) plays a crucial role in diverse inflammatory reactions. Although the food bioactive compound naringenin (NAR) exerts various useful effects, including antitussive, anti-inflammatory, hepatoprotective, renoprotective, antiarthritic, antitumor, antioxidant, neuroprotective, antidepressant, antinociceptive, antiatherosclerotic, and antidiabetic effects, the modulatory mechanism of NAR on OSM expression in neutrophils has not been specifically reported. In the current work, we studied whether NAR modulates OSM release in neutrophil-like differentiated (d)HL-60 cells.

Tribuli Fructus alleviates 1-methyl-4-phenyl 1,2,3,6-tetrahydropyridine (MPTP)-induced Parkinson's disease by suppressing neuroinflammation via JNK signaling.

Parkinson's disease (PD) is a neurodegenerative disease characterized by the loss of dopaminergic neurons. In particular, neuroinflammation associated with phosphorylation of c-Jun N-terminal kinase (JNK) is likely to cause the death of dopaminergic neurons. Therefore, protecting dopaminergic neurons through anti-neuroinflammation is a promising therapeutic strategy for PD.

The analgesic effect of acupuncture in neuropathic pain: regulatory mechanisms of DNA methylation in the brain.

Recent research has demonstrated that chronic pain, resulting from peripheral nerve injury, leads to various symptoms, including not only allodynia and hyperalgesia but also anxiety, depression, and cognitive impairment. These symptoms are believed to arise due to alterations in gene expression and neural function, mediated by epigenetic changes in chromatin structure. Emerging evidence suggests that acupuncture can modulate DNA methylation within the central nervous system, contributing to pain relief and the mitigation of comorbidities.

Peripheral Rho-associated protein kinase activation mediates acupuncture analgesia.

Background: Acupuncture has been proven effective for various types of pain, and peripheral molecular signals around acupuncture-treated areas have been suggested to contribute to the analgesic effects of acupuncture. However, the underlying mechanism from these peripheral molecular signals to central ones remains unclear. The purpose of this study was to investigate whether peripheral Rho-associated protein kinase (ROCK) activation induced by acupuncture treatment mediates acupuncture analgesia, and also to investigate the relationship between ROCK activation and extracellular signal-regulated kinase (ERK), which has previously been proven to mediate acupuncture analgesia and other related molecular changes during acupuncture.

Gut Microbiota Regulation by Acupuncture and Moxibustion: A Systematic Review and Meta-Analysis.

There have been numerous studies investigating the impact of acupuncture and/or moxibustion on the gut microbiota, but the results have been inconclusive. Therefore, we conducted a systematic review and meta-analysis that included both preclinical and clinical studies to assess the current evidence regarding the effects of acupuncture on gut microbiota changes. We collected relevant studies from EMBASE and PubMed, collected outcomes including diversity and relative abundance measures of the gut microbiome, and the summarized effect estimates were calculated using the ratio of means (ROM) with 95% confidence intervals.

Acupuncture ameliorates atopic dermatitis by modulating gut barrier function in a gut microbiota-dependent manner in mice.

Objective: Atopic dermatitis (AD) is a chronic inflammatory skin disease that may be linked to changes in the gut microbiome. Acupuncture has been proven to be effective in reducing AD symptoms without serious adverse events, but its underlying mechanism is not completely understood. The purpose of this study was to investigate whether the potential effect of acupuncture on AD is gut microbiota-dependent.

Central Role of Hypothalamic Circuits for Acupuncture's Anti-Parkinsonian Effects.

Despite clinical data stretching over millennia, the neurobiological basis of the effectiveness of acupuncture in treating diseases of the central nervous system has remained elusive. Here, using an established model of acupuncture treatment in Parkinson's disease (PD) model mice, we show that peripheral acupuncture stimulation activates hypothalamic melanin-concentrating hormone (MCH) neurons via nerve conduction. We further identify two separate neural pathways originating from anatomically and electrophysiologically distinct MCH neuronal subpopulations, projecting to the substantia nigra and hippocampus, respectively.

Peripheral mast cells derive the effects of acupuncture in Parkinson's disease.

This research investigates the peripheral mechanisms of acupuncture in treating Parkinson's disease (PD), a progressive neurodegenerative disorder marked by motor impairments. While the central mechanisms of acupuncture have been extensively studied, our focus lies in the peripheral mechanisms at the acupoints, the sites of acupuncture signal initiation. Employing a PD model, we analyzed the local responses to acupuncture stimulation at these points.
