Immunomodulation Effects of Schizonepeta tenuifolia Briq. on the IgE-Induced Allergic Model of RBL-2H3 Cells

Figure 2

The evolution of proinflammatory cytokines 48 and 72 hrs after treating IgE-induced RBL-2H3 cells with 10, 50, or 100 μg/mL ST shows that the inflammatory cytokines released by RBL-2H3 cells tend to decrease with increasing doses of ST, especially IFN-γ and TNF-α. when compared with controls after 48 hrs of ST treatment; when compared with controls after 72 hrs of ST treatment; and when comparing data between 48 and 72 hrs of treatment.
