During the past era, small molecules derived from various plants have attracted extensive attention for their versatile medicinal benefits. Among these, one organic molecule called mangiferin from certain plant species including mangoes and honey bush tea is widely used in treating inflammation. In this study, a LPS-induced mastitis model in mouse is established to investigate the anti-inflammatory effects and mechanism of mangiferin. The result shows that mangiferin significantly alleviates LPS-induced histopathology, meanwhile, also decreases LPS-induced MPO activity. Furthermore, mangiferin treatment remarkably impeded the expression of pro-inflammatory cytokines TNF-α, IL-1β, and IL-6. In addition, mangiferin was found to inhibit LPS-induced NF-ĸB and NLRP3 inflammasome activation. In conclusion, these results suggested that LPS-induced mastitis can be abated by mangiferin through inhibiting NF-ĸB and NLRP3 signaling pathways.
