Effects of saikosaponin-d on the functions and morphology of macrophages
International Journal of Immunopharmacology
|January 1, 1991
Abstract:
The effects of saikosaponin-d, isolated from Bupleurum Radix, on phagocytosis and spreading of mouse peritoneal macrophages were investigated. Macrophages from saikosaponin-d-treated mice showed a significant increase in spreading activity followed by an increase in phagocytic activity. An intense distribution of microfilaments and microtubules was also observed in these macrophages by immunofluorescence microscopy.
Insights
Saikosaponin-d from Bupleurum Radix enhances macrophage activity. Treatment with this compound significantly boosts macrophage spreading and phagocytosis, indicating potential immunomodulatory effects.
