Our aim was to directly demonstrate the presence of positive feedback in the ATP-induced release of IL-6 into the supernatant of human skeletal muscle cultures. The total release (production) of IL-6 was reduced for higher volumes of supernatant, when the secreted IL-6 molecules are more diluted, and enhanced when the supernatant volume was lower. In addition, secretion was impaired both by tocilizumab, a blocker of human IL-6 receptors, and by the soluble form of the receptor. The secretion in response to ATP was also inhibited by treatment with the endocytosis inhibitor dynasore, and by disruption of the acidic gradient of the endocytic compartment using different methods (chloroquine, NH4Cl or monensin). IL-6 secretion was also impaired by NED-19, a specific inhibitor of the two pore channels receptor mediating Ca2+ release from the endolysosomal compartment. IL-6 and ATP increased IL-6 mRNA levels, an effect blocked by tocilizumab. Altogether, our results demonstrate that ATP-secreted IL-6 activates a positive loop based on IL-6 receptors, endocytosis, two pore channels and IL-6 transcription. Given the importance of muscle IL-6 as a systemic regulator and as an inflammatory mediator, our study can help to understand muscle pathophysiology.</div></div>","PeriodicalId":12004,"journal":{"name":"European journal of pharmacology","volume":null,"pages":null},"PeriodicalIF":4.2,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142418529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A rheumatoid arthritis model was established by the intradermal injection of CFA into the paws of rats. Mechanical withdrawal threshold (MWT), thermal withdrawal latency (TWL), ankle swelling and paw edema were used to evaluate the effects of DXL-A-24. Bone erosion and bone mineral density (BMD) were observed using micro-computed tomography. Receptor blocking test, western blotting, and enzyme-linked immunosorbent assay were performed to explore the mechanisms. Administration of DXL-A-24 (1, 0.5, 0.25 mg/kg, i.g.) dose-dependently increased the MWT and TWL, while alleviating ankle and paw swelling in CFA rats. The effects were blocked by peripheral α7 nicotinic or M4 muscarinic receptor antagonists. DXL-A-24 improved bone erosion and BMD, as well as downregulated the overexpression of Cav3.2, pJAK2, pSTAT3, pIκBα, pNF-κB p65, c-Fos and TNF-α proteins that were induced by CFA. In conclusion, this study shows, for the first time, that DXL-A-24 improves bone erosion and BMD and exhibits obvious anti-arthritic effects in CFA rats. The mechanism may be related to activating the peripheral α7 nicotinic and M4 muscarinic receptors, reducing Cav3.2 expression, and suppressing JAK2/STAT3 and IκBα/NF-κB p65 inflammatory signaling pathways, ultimately inhibiting inflammation-related proteins TNF-α and c-Fos.</div></div>","PeriodicalId":12004,"journal":{"name":"European journal of pharmacology","volume":null,"pages":null},"PeriodicalIF":4.2,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142406282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In some individuals, clinically used polymyxins can cause acute hypersensitivity reactions through mast cell activation, with a recent study attributing this effect to activation of the MAS-related G protein-coupled receptor X2 (MRGPRX2). In the present study, HEK293 cells expressing human MRGPRX2 and the human mast cell line LAD2 were used to characterize the activity of the broader family of polymyxins. Octapeptin C4, polymyxin B and colistin produced concentration-dependent calcium mobilization, degranulation, and CCL-2 (MCP-1) release in LAD2 mast cells, with the former being highly potent. CRISPR-Cas9 knockdown of MRGPRX2 in LAD2 cells and a MRGPRX2 inverse agonist caused a significant reduction in calcium mobilization, degranulation, and CCL-2 release, demonstrating dependency on MRGPRX2 expression. In contrast, polymyxin nonapeptides were far less potent calcium mobilisers and failed to induce functional degranulation in LAD2 cells. Our results confirm that activation of mast cells induced by polymyxin-related antibiotics is MRGPRX2-dependent and reveal that octapeptin C4 might be more liable, whilst nonapeptides are less liable, to trigger immediate hypersensitivity reactions clinically. The mechanism underpinning the difference in MRGPRX2 activation between polymyxin-related antibiotics is important to better understand as it may help design new, safer polymyxins and guide the optimal clinical use of existing polymyxin drugs.</div></div>","PeriodicalId":12004,"journal":{"name":"European journal of pharmacology","volume":null,"pages":null},"PeriodicalIF":4.2,"publicationDate":"2024-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142399797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
