Study on the Inhibitory Effects of Ephedra Aconite Asarum Decoction on LPS-Induced Dendritic Cells

الملخص EN

Dendritic cells (DCs) can secrete cytokines stimulated by lipopolysaccharide (LPS), which leads to not just acute inflammatory responses but also Th1 polarization.

Furtherly, chronic inflammation or autoimmune diseases could be triggered.

As a classic Traditional Chinese Medicine formula, Ephedra Aconite Asarum Decoction with the main ingredients of ephedrine and hypaconitine can show effect on anti-inflammation and immunoregulation.

But it remains unclear whether Ephedra Aconite Asarum Decoction controls DCs.

In this study, we investigated the effects of Ephedra Aconite Asarum Decoction on LPS-induced bone marrow-derived DCs (BMDCs) in vitro.

We found that Ephedra Aconite Asarum Decoction lowered surface costimulators on DCs and reduced the expression of Th1 type cytokines.

Yet it is slightly beneficial for shifting to Th2.

Our work reveals that the Ephedra Aconite Asarum Decoction can regulate Th1 inflammation through intervening DCs.
