Abstract:
Aim To study the effect of Tongxinluo on the polarization of macrophages to type M2 and M1, and on Notch signaling pathway.Methods THP-1 was respectively induced by PMA and IL-4 or LPS to M2 and M1 type polarized macrophages, and treated by Tongxinluo.The expressions of marker molecules IL-10, TNF-α, IL-6 and protein of Notch signaling pathway were detected.Results The level of IL-10 increased in M2 group and there was no statistical difference on the level of IL-6 and TNF-α;the level of IL-10 decreased and IL-6, TNF-α increased in M1 group;the level of IL-10 increased and IL-6,TNF-α decreased in TXL group.There was no statistical difference in the expression of active Notch-1, DLL4 and Hes-1 between control group and M2 group;the expression of active Notch-1, DLL4 and HES-1 increased significantly in M1 group;the expression of active Notch-1, DLL4 and HES-1 decreased significantly in TXL group;there was no significant difference in the expression of Notch-1 protein in each group.Conclusion The polarization of macrophages to M1 type can be inhibited by Tongxinluo, and its mechanism may be related to the inhibition of activation of Notch-1 signaling pathway.
