Li H, Ward SJ. Paclitaxel-Associated Mechanical Sensitivity and Neuroinflammation Are Sex-, Time-, and Site-Specific and Prevented through Cannabigerol Administration in C57Bl/6 Mice. Int J Mol Sci 2024; 25:4277. [PMID: 38673862 PMCID: PMC11050247 DOI: 10.3390/ijms25084277] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2024] [Revised: 04/04/2024] [Accepted: 04/08/2024] [Indexed: 04/28/2024] Open
Abstract
Chemotherapy-induced peripheral neuropathy (CIPN) is one of the most prevalent and dose-limiting complications in chemotherapy patients. One identified mechanism underlying CIPN is neuroinflammation. Most of this research has been conducted in only male or female rodent models, making direct comparisons regarding the role of sex differences in the neuroimmune underpinnings of CIPN limited. Moreover, most measurements have focused on the dorsal root ganglia (DRG) and/or spinal cord, while relatively few studies have been aimed at characterizing neuroinflammation in the brain, for example the periaqueductal grey (PAG). The overall goals of the present study were to determine (1) paclitaxel-associated changes in markers of inflammation in the PAG and DRG in male and female C57Bl6 mice and (2) determine the effect of prophylactic administration of an anti-inflammatory cannabinoid, cannabigerol (CBG). In Experiment 1, male and female mice were treated with paclitaxel (8-32 mg/kg/injection, Days 1, 3, 5, and 7) and mechanical sensitivity was measured using Von Frey filaments on Day 7 (Cohort 1) and Day 14 (Cohort 2). Cohorts were euthanized on Day 8 or 15, respectively, and DRG and PAG were harvested for qPCR analysis of the gene expression of markers of pain and inflammation Aig1, Gfap, Ccl2, Cxcl9, Tlr4, Il6, and Calca. In Experiment 2, male and female mice were treated with vehicle or 10 mg/kg CBG i.p. 30 min prior to each paclitaxel injection. Mechanical sensitivity was measured on Day 14. Mice were euthanized on Day 15, and PAG were harvested for qPCR analysis of the gene expression of Aig1, Gfap, Ccl2, Cxcl9, Tlr4, Il6, and Calca. Paclitaxel produced a transient increase in potency to produce mechanical sensitivity in male versus female mice. Regarding neuroinflammation, more gene expression changes were apparent earlier in the DRG and at a later time point in the PAG. Also, more changes were observed in females in the PAG than males. Overall, sex differences were observed for most markers at both time points and regions. Importantly, in both the DRG and PAG, most increases in markers of neuroinflammation and pain occurred at paclitaxel doses higher than those associated with significant changes in the mechanical threshold. Two analytes that demonstrated the most compelling sexual dimorphism and that changed more in males were Cxcl9 and Ccl2, and Tlr4 in females. Lastly, prophylactic administration of CBG protected the male and female mice from increased mechanical sensitivity and female mice from neuroinflammation in the PAG. Future studies are warranted to explore how these sex differences may shed light on the mechanisms of CIPN and how non-psychoactive cannabinoids such as CBG may engage these targets to prevent or attenuate the effects of paclitaxel and other chemotherapeutic agents on the nervous system.

Tibetan medicine Ruyi Zhenbao Pill ameliorates neuropathic pain by inhibiting the CXCL10-CXCR3 pathway in spinal cord of spinal nerve ligation model. JOURNAL OF ETHNOPHARMACOLOGY 2024; 323:117653. [PMID: 38163561 DOI: 10.1016/j.jep.2023.117653] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/26/2023] [Revised: 12/18/2023] [Accepted: 12/20/2023] [Indexed: 01/03/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ruyi Zhenbao Pill (RYZBP) is a traditional Tibetan medicine that has been used for over 300 years in China to treat neurological diseases, specifically neuropathic pain (NP). However, its characteristics and mechanism of action in treating NP remains unclear. AIM OF THE STUDY Based on animal experiments and transcriptomics to evaluate the characteristics and mechanism of RYZBP in treating NP. METHODS Mice were divided into six groups using random assignment: sham-operation group, spinal nerve ligation (SNL) group, RYZBP low (0.65 g kg-1), medium (1.30 g kg-1), high (2.60 g kg-1) doses groups, and positive drug pregabalin (PGB, 0.05 g kg-1) group. Mice received intragastrical administered for 14 consecutive days. SNL and intrathecal injection models were employed. The analgesic effects were assessed using the Von Frey test, Acetone test, and Hot Plate test. L5 spinal dorsal horns were collected for transcriptomics on day 15. The potential signaling pathways and Hub genes of RYZBP to ameliorate NP were obtained through transcriptomics and network pharmacology. Molecular docking was utilized to evaluate the binding ability of candidate active ingredients with the Hub genes. Finally, western blot (WB) and immunofluorescence (IF) were used to validate the predicted targets. RESULTS RYZBP demonstrated a dose-dependent alleviation of mechanical allodynia, cold and heat stimulus-induced pain in SNL mice. Transcriptomics analysis identified 24 differentially expressed genes, and pathway enrichment analysis revealed that the CXCL10-CXCR3 signal axis may be the primary biological pathway through which RYZBP relieve NP. Molecular docking test indicated that the active ingredient in RYZBP exhibit a strong affinity for the target protein CXCL10. WB and IF tests showed that RYZBP can significantly inhibit CXCL10 and CXCR3 and its downstream molecules expression in the spinal dorsal horn of SNL mice. Additionally, intrathecal injection of rmCXCL10 worsened pain hypersensitivity, while RYZBP was able to suppress the pain hypersensitivity response induced by rmCXCL10 and reduce the expression levels of CXCL10 and CXCR3 and its downstream molecules. CONCLUSION RYZBP had a significant analgesic effect on NP model, and this effect may be related to inhibiting the CXCL10-CXCR3 pathway in the spinal dorsal horn.

[PMID: 37548853 PMCID: PMC10657789 DOI: 10.1007/s12035-023-03537-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Accepted: 07/21/2023] [Indexed: 08/08/2023]
Abstract
The object of our work was to observe whether the Mongolian medicine Eerdun Wurile (EW) improve postoperative cognitive dysfunction (POCD) by affecting the TLR4/NF-κB. Mice (6-8-week-old male C57BL/6 J) were selected to establish an animal model of POCD by combining intracerebroventricular injection of lipopolysaccharide and nephrectomy; EW formulation and EW basic formulation were administered intra-gastrically for 7 consecutive days. The cognitive performance was assessed by Morris water maze test. H&E staining was examined to detect alterations in hippocampal tissue. Immunohistochemical staining was performed to evaluate MyD88, NF-κB, TLR4, iNOS, and IBA-1 expressions; Western blotting and RT-qPCR were performed to evaluate MyD88, NF-κB, and TLR4. The expressions of IL-6, IL-1β, and TNF-α were evaluated by ELISA. Intracerebroventricular injection of lipopolysaccharide combined with nephrectomy induced cognitive dysfunction in mice, stimulated TLR4/NF-κB and microglia, and promoted the secretion of murine TNF-α, IL-1β, and IL-6. EW formulation and EW basic formulation treatment are able to suppress the TLR4/NF-κB pathway activation and microglia, and the serum cytokine secretions related to proinflammation, and restore the cognitive performance. EW formulation and EW basic formulation can improve POCD in mice, and TLR4/NF-κB pathway seems to be one of the important mechanisms in EW's improvement of POCD.

[PMID: 37680717 PMCID: PMC10482050 DOI: 10.3389/fphar.2023.1190920] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2023] [Accepted: 08/07/2023] [Indexed: 09/09/2023] Open
Abstract
Background: Migraine is a common neurovascular disorder with typical throbbing and unilateral headaches, causing a considerable healthcare burden on the global economy. This research aims to prepare chitosan-alginate (CS-AL) nanoparticles (NPs) containing Foshousan oil (FSSO) and investigate its potential therapeutic effects on the treatment of migraine. Methods: FSSO-loaded CS-AL NPs were prepared by using the single emulsion solvent evaporation method. Lipopolysaccharide (LPS)-stimulated BV-2 cells and nitroglycerin (NTG)-induced migraine mice were further used to explore anti-migraine activities and potential mechanisms of this botanical drug. Results: FSSO-loaded CS-AL NPs (212.1 ± 5.2 nm, 45.1 ± 6.2 mV) had a well-defined spherical shape with prolonged drug release and good storage within 4 weeks. FSSO and FSSO-loaded CS-AL NPs (5, 10, and 15 μg/mL) showed anti-inflammatory activities in LPS-treated BV-2 cells via reducing the levels of pro-inflammatory cytokines such as tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), interleukin-6 (IL-6), and nitric oxide (NO), but elevating interleukin-10 (IL-10) expressions. Moreover, FSSO-loaded CS-AL NPs (52 and 104 mg/kg) raised pain thresholds against the hot stimulus and decreased acetic acid-induced writhing frequency and foot-licking duration in NTG-induced migraine mice. Compared with the model group, calcitonin gene-related peptide (CGRP) and NO levels were downregulated, but 5-hydroxytryptamine (5-HT) and endothelin (ET) levels were upregulated along with rebalanced ET/NO ratio, and vasomotor dysfunction was alleviated by promoting cerebral blood flow (CBF) in the FSSO-loaded CS-AL NPs (104 mg/kg) group. Conclusion: FSSO-loaded CS-AL NPs could attenuate migraine via inhibiting neuroinflammation in LPS-stimulated BV-2 cells and regulating vasoactive substances in NTG-induced migraine mice. These findings suggest that the FSS formula may be exploited as new phytotherapy for treating migraine.

Abstract
Migraine is a disabling neurovascular disease with unilateral or bilateral pulsatile headache, which intensively affects human health and quality of life due to high morbidity worldwide. Migraine is commonly accompanied by abnormal pain sensitization, neuroinflammatory response, and vasomotor dysfunction. Owing to the management dilemmas of migraine, there is an urgent need to develop effective and low-cost therapies. In recent years, herbal medicines as a promising strategy with analgesic activity and minor side effect, have been proposed for the prevention and treatment of migraine. Considering the lack of a review integrating experimental studies regarding the herbal treatment of migraine, this review systematically summarizes the important potential applications of herbal medicines in ameliorating migraine via multiple therapeutic targets and pathways, as well as provides a reference for further development of novel antimigraine drugs.

Abstract
The purpose of this research was to explore the effect and mechanism of emodin in interfering with nitroglycerin-induced migraine rats. We carried out behavioral research within 2 h post-nitroglycerin (NTG) injection, and blood samples were collected through the abdominal aorta for measurements of nitric oxide (NO), calcitonin gene-related peptide (CGRP), substance P (SP), tumor necrosis factor (TNF-α) and cyclic guanosine monophosphate (cGMP) levels. Immunohistochemistry was adopted to detect the activation of c-Fos immunoreactive neurons in brain tissues. The number and integrated optical density (IOD) of c-Fos positive cells were measured using Image-Pro Plus. Western blotting was applied to detect the levels of PKG protein in rat brain tissues. The results showed that emodin can alleviate the pain response of migraine rats and significantly reduce the levels of NO, CGRP, SP, TNF-α and cGMP in migraine rats. In addition, emodin can significantly reduce the number of c-Fos positive cells and the IOD value. Moreover, the expression of PKG protein was significantly inhibited by emodin. Therefore, it is inferred that emodin can relieve migraine induced by NTG through the cGMP-PKG pathway, and can be used as a potential botanical medicine for the treatment of migraine.

JOURNAL OF ETHNOPHARMACOLOGY 2021; 274:114020. [PMID: 33716080 DOI: 10.1016/j.jep.2021.114020] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/16/2021] [Revised: 03/04/2021] [Accepted: 03/08/2021] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The Zhenbao pill (ZBP) is composed of 29 traditional Chinese medicines and has been proven to exhibit a valid therapeutic effect in nervous system diseases, such as stroke and hemiplegia sequelae. AIM OF THE STUDY Whether ZBP has a protective effect on vascular endothelial cells remains unknown. In this study, we established hydrogen peroxide (H2O2)-induced oxidative injury in human umbilical vein endothelial cells (HUVECs) as an in vitro model to investigate the pharmacological effects of ZBP. MATERIALS AND METHODS Following the intragastric administration of ZBP (0.25, 0.5, and 1 g/kg for seven days) in rats, drug-containing serum was obtained and cultivated with HUVECs before H2O2 treatment. The viability of HUVECs in the presence of H2O2 was measured by Cell Counting Kit-8 assay, lactate dehydrogenase assay, and flow cytometry. Furthermore, we estimated the effects of ZBP on the production of reactive oxygen species (ROS) and mitochondrial membrane potential (MMP). Autophagic puncta were detected using a fluorescence microscope. Western blotting and real-time polymerase chain reaction were used to detect the expression levels of several genes associated with apoptosis and autophagy. RESULTS Drug-containing serum separated from rats at 1 h after intragastric administration of ZBP (0.5 g/kg) significantly offered a protective effect to HUVECs and reduced cell apoptosis rates. Meanwhile, ZBP-containing serum also repressed ROS production induced by H2O2 exposure and maintained MMP. Further investigation revealed that ZBP-containing serum effectively reduced the accumulation of autophagic puncta. ZBP-mediated inhibition on cell autophagy was found to contribute to ameliorating cell apoptosis. Western blotting also confirmed that ZBP maintained AKT and mTOR phosphorylation and antagonized the imbalance of BCL2/BAX, thereby protecting cells from apoptosis. CONCLUSION Taken together, our data indicate that ZBP inhibits ROS production, mitochondrial damage, cell autophagy, and cell apoptosis. ZBP can offer protection to vascular endothelial cells against oxidative injury through the antagonism of apoptosis and autophagy. Thus, this study enhances the understanding of the therapeutic effects and mechanisms of ZBP in the process of recovery from myocardial and cerebral ischemic stroke.
