ABSTRACT
We explore and verify the optimized condition for HEK-Blue IL-17 screening model, and screen the compounds that inhibits IL-17-medited signaling pathway. HEK-Blue IL-17 cells (5×104 cells per well) were seeded into the 96 plates followed by different concentrations of IL-17A or IL-17F alone, or in combination with tested compounds for 16 h. Then, the supernatant medium was incubated with QUANTI-Blue for 1 or 3 h to detect the OD value at λ655nm. The secreted alkaline phosphatase (SEAP) production was an index of IL-17-mediated signaling activation in HEK-Blue IL-17 cells. We found that both IL-17A and IL-17F can significantly activate the IL-17 signaling pathway in HEK-Blue IL-17 cells. The available dosage of IL-17A and IL-17F were 10 and 100 ng·mL-1, respectively. The reaction time of SEAP and QUANTI-Blue was 1 h. In this model, arctigenin and epigallocatechin gallate (EGCG) could inhibit the IL-17A and IL-17F-mediated signaling pathway. This established and optimized screening model of HEK-Blue IL-17 cells was suitable for screening inhibitors of IL-17-mediated signaling pathway.
