Inhibition of proinflammatory macrophage responses and lymphocyte proliferation in vitro by ethyl acetate leaf extract from Daphne gnidium.

abstract：:We previously showed that DT-5461a, a lipid A analog, has antitumor activity and relatively low toxicity in animals. To clarify its immunostimulatory effect we have studied the cytokine inducibility of DT-5461a and the mechanism involved in the cytokine expression in macrophages. While the activity is lower than that ...
