In addition, cryptotanshinone (3) was able to promote the production of tumor necrosis factor (TNF)-α, IL-1β, and IL-12 by DCs without inducing the production of IL-10, preferentially promoting the immune response of type 1 helper (Th1) cells, and had the unique dual ability to inhibit the proliferation of lung cancer cells and induce the maturation of DCs [61]. Here, TNF is linked to lung cancer.
