Ethanolic extract of Pereskia aculeata induces Anti-Inflammatory Responses through P38/MK2/TTP-mediated signaling pathway.
Pakistan journal of pharmaceutical sciences(2023)
摘要
Pereskia aculeata Miller, a member of the Cactaceae family, is a plant with pharmacological potential due to its containing compounds with various biological activities, which include anti-inflammatory, anti-cancer and analgesic activities. In this study, we evaluated the anti-inflammatory effects of an ethanolic extract of P. aculeata Miller (EEPA) and the signalling pathways by which it exerts these effects. In vitro, EEPA inhibited the secretion of inflammatory factors NO, IL-6 and PGE in ipopolysaccharide-stimulated RAW264.7 macrophages (P<0.05). Treatment of RAW264.7 cells with EEPA also significantly decreased the levels of P-P38 and P-MK2, while upregulating the expression of TTP (P<0.05). In vivo anti-inflammatory activity assays revealed that EEPA reduced the degree of foot and joint swelling, the splenic index and the serum concentrations of TNF-α and IL-6 in in adjuvant-induced arthritis rats (P<0.05). Similarly, EEPA treatment of mice inhibited the acetic acid-induced exudation of Evans blue dye from peritoneal capillaries and significantly prolonged heat-stimulated pain response time (P<0.05). Taken together, these results suggest that EEPA exerts anti-inflammatory effects in vitro and in vivo. Thus, this study provides experimental and technical support for the development of a novel anti-inflammatory treatment based on P. aculeata Miller.
