Anti-Allergic Effects of Quercetin and Quercetin Liposomes in RBL-2H3Cells

BACKGROUND: Quercetin is a kind of flavonoid with important bioactivities, such as hypoglycemic, antioxidant, anti-inflammatory, and anti-allergic properties. Although it is unstable, it is worth exploring how to better exert its anti-allergic effect. OBJECTIVE: The current study aimed to elucidate the anti-allergic effect of quercetin liposomes on RBL-2H3 cells in vitro. METHODS: , IL-4, IL-8, and MCP-1. RESULTS: The results showed that quercetin liposomes could significantly restrain the release of β-hexosaminidase and histamine, calcium influx, and the expression of inflammatory factors, whose effect is stronger than quercetin. CONCLUSION: Collectively, our research suggests that the quercetin liposome can be used as a potential allergy antagonist.
