[The effects of recombinant human beta-defensin-3 on expression of interleukin-17A and interleukin-22 in BEAS-2B cell].

Objective: To research the effects of recombinant human beta-defensin-3 (hBD-3) on expression of interleukin-17A (IL-17A) and interleukin-22 (IL-22) in BEAS-2B cell.

Methods: The BEAS-2B cells were stimulated with different concentrations of hBD-3 for 6 hours and 24 hours, respectively. Toll-like receptor 2 (TLR2), IL-17A and IL-22 mRNA expression levels were determined by real-time PCR, and the expression levels of IL-17A and IL-22 protein were examined by enzyme linked immune-sorbent assay.
