倍半萜内酯(Sesquiterpene lactones,SL)是用于治疗炎症性疾病和其他疾病的传统医学中的多种药用植物的活性成分。 在这项研究中,我们评估了是否budlein A调节先天性和适应性免疫细胞,如中性粒细胞和淋巴细胞的激活。 我们的研究小组已经研究了几种植物物种,并分离、鉴定了几种化合物,并评估了它们的医学潜力。Budlein A是从Buddlejiformis和A. robusta(菊科),并显示出抗炎和抗伤害感受活性。在了解植物源性物质如何调节先天性和适应性免疫细胞的激活方面取得的进展导致了人类疾病新疗法的开发。 Budlein A抑制MPO活性、IL-6、CXCL 8、IL-10和IL-12产生并诱导中性粒细胞凋亡。与此相反,Budlein A抑制淋巴细胞增殖和IL-2、IL-10、TGF-β和IFN-γ的产生,但不导致细胞死亡。 总的来说,我们的研究结果表明,花蕾素A显示出不同的免疫细胞的免疫调节作用。
Sesquiterpene lactones (SLs) are the active constituents of a variety of medicinal plants used in traditional medicine for the treatment of inflammatory diseases and other ailments. In this study, we evaluated whether budlein A modulates the activation of innate and adaptive immune cells such as neutrophils and lymphocytes. Our research group has investigated several plant species and several compounds have been isolated, identified, and their medical potential evaluated. Budlein A is a SL isolated from the species Aldama buddlejiformis and A. robusta (Asteraceae) and shows anti-inflammatory and anti-nociceptive activities. Advances in understanding how plant-derived substances modulate the activation of innate and adaptive immune cells have led to the development of new therapies for human diseases. Budlein A inhibited MPO activity, IL-6, CXCL8, IL-10, and IL-12 production and induces neutrophil apoptosis. In contrast, budlein A inhibited lymphocyte proliferation and IL-2, IL-10, TGF-β, and IFN-γ production, but it did not lead to cell death. Collectively, our results indicate that budlein A shows distinct immunomodulatory effects on immune cells.
