TGs retained in the intestine or lymphatics can be mobilized by the gut peptide glucagon-like peptide 2 (GLP-2) and other stimuli. Our previous published data demonstrated that GLP-2 enhances lymph flow by acting distal to the enterocyte, specifically by enhancing lacteal contractility, in an enteric nervous system–dependent fashion. The objective of the present study was to further explore various intermediates in the signaling pathway whereby GLP-2 enhances mesenteric lymph flow. In this study we focused on the roles of vascular endothelial growth factor receptor 3 (VEGFR3) and myosin light chain 2 (MLC2), known to play important roles in lymphangiogenesis and lymphatic contractility, respectively.</div></div><div><h3>Methods</h3><div>A rat lymph fistula model was utilized in this study. An intraduodenal lipid bolus was applied to the rats 5 hours before the following intraperitoneal (i.p.) administrations: 1) saline (placebo), 2) GLP-2, 3) GLP-2 + MAZ-51 (a VEGFR3 inhibitor), 4) GLP-2 + SAR131675 (a second VEGFR3 inhibitor), 5) GLP-2 + ML-7 (a MLCK inhibitor). Lymph flow and TG output were assessed for 60 minutes after the i.p. administrations. In another set of animals, post-i.p. administration, tissue samples were collected to quantify VEGFR3 and MLC2 activation (via phosphorylation).</div></div><div><h3>Results</h3><div>We showed that GLP-2 treatment acutely activated VEGFR3 and MLC2, and that inhibition of VEGFR3 (via MAZ-51/SAR131675) and MLC2 (via ML-7) abolished GLP-2-induced lymph flow and TG output. Furthermore, VEGFR3 inhibition blocked MLC2 activation.</div></div><div><h3>Conclusion</h3><div>Our data suggest that the activation of VEGFR3 and MLC2 play critical roles in GLP-2’s enhancement of chylomicron secretion and that VEGFR3 activation is an important intermediary step in GLP-2’s activation of MLC2.</div></div>","PeriodicalId":73130,"journal":{"name":"Gastro hep advances","volume":"4 4","pages":"Article 100605"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143777457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
