Fig. 3. A quantitative polymerase chain reaction approach was used to assess the expression of specific cytokines (IFN-γ, IL-22, IL-17, and IL-23) and anti-microbial peptides (iNOS, Reg3β, S100A8) in the indicated samples. Data are means ± SD.
IL, interleukin; APP, Actinobacillus pleuropneumonniae; IFN, interferon; iNOS, inducible nitric oxide synthase.
