Umbelliprenin induced both anti-inflammatory and regulatory cytokines in C57/BL6 mice
Authors
Abstract:
Objective(s): Umbelliprenin is a prenyloxy-coumarin with pharmacologically polyvalent activity. Several studies have shown its anti-inflammatory, anti-tumor, antioxidant, and antigenotoxic activity, and other functions. However, the exact mechanism of action of this compound on the immune response has not yet been shown. Here, we investigated umbelliprenin effects on the predominance of Th1 and Th2 responses in normal C57/BL6 mice. Materials and Methods: Umbelliprenin (2.5 mg/200 µl IP) were administered to six C57/BL6 mice every other day for 8 days. Paraffin and PBS-injected mice were enrolled as solvent and control groups, respectively (n=6 mice/group). IL-10, IFN-γ, and IL-4 levels were determined in sera and also in splenocytes culture supernatants in the presence of Con A (3 µg/ml) after 72 hr. H&E staining of paraffin embedded blocks was performed for lung and liver tissues of mice. Results: Umbelliprenin could significantly increase the secretion of IFN-γ and IL-4 in sera and IL-10 in splenocytes cultures. Comparison of IFN-γ /IL-4 in the sera and splenocytes culture supernatants showed lower ratios in umbelliprenin treated mice than in solvent and untreated groups. Conclusion: The in vivo study showed that umbelliprenin could induce anti-inflammatory responses via the predominance of Th2 cells and some regulatory responses in C57/BL6 mice.

Anti-inflammatory Effect of Ethanolic Extract of Euphorbia myrsinites in Lipopolysaccharide-induced Septic Shock in Mice
Background and purpose: Many herbs including Euphorbia have immunomodulatory properties. The aim of this study was to evaluate the immunomodulatory effects of the ethanolic extract of E.myrsinites. Materials and methods: In this experimental study, 40 Swiss albino male mice were randomly divided into 4 groups. Group A included healthy mice, group B was induced by lipopolysaccharide (LPS), grou...

The anti-inflammatory cytokines are a series of immunoregulatory molecules that control the proinflammatory cytokine response. Cytokines act in concert with specific cytokine inhibitors and soluble cytokine receptors to regulate the human immune response. Their physiologic role in inflammation and pathologic role in systemic inflammatory states are increasingly recognized. Major anti-inflammato...

Background: Thiamine (VitB1) is a vitamin with various important physiological functions and postulated therapeutic effects. Its use as an analgesic in neuropathic pain has been undergoing in clinical settings. However, there has been little experimental investigation on this effect. In this study, anti-nociceptive and anti-inflammatory effects of thiamine were investigated in mice. Methods: T...

Background: The levels of IL-13, IL-4, IL-1B, TNF-α and IL-10 alter in the colon of people with ulcerative colitis. previous studies, it was found that shilajit (asphaltum) was effective in the improvement of ulcerative colitis.we guessed that the shilajit has been able to improve the ulcerative colitis by affecting the amount of cytokines. Objective: The aim of the present study was to investi...
