Figure Lengend Snippet: CSF3 enhances the immune response to ALV-J via the NFκB signaling pathway. (A) Western blot analysis of p52, p100, phosphorylated p65 (p-p65), IκBα, and phosphorylated IκBα (p-IκBα) protein following CSF3 overexpression in DF-1 cells. (B) Quantification of protein levels in (A) based on relative grayscale values. (C) Western blot analysis of p52, p100, phosphorylated p65 (p-p65), IκBα, and phosphorylated IκBα (p-IκBα) protein following CSF3 knockdown in DF-1 cells. (D) Quantification of protein levels in (C) based on relative grayscale values. (D, E) RT-qPCR analysis of TNF-α, IL-1β , and IL-6 mRNA expression following CSF3 overexpression (D) or knockdown (E) in DF-1 cells. (F, G) ELISA measurement of TNF-α, IL-1β, and IL-6 protein levels following CSF3 overexpression (F) or knockdown (G) in DF-1 cells. (H, I) RT-qPCR analysis of TNF-α, IL-1β , and IL-6 mRNA expression following CSF3 overexpression (H) or knockdown (I) in CEF cells. (J, K) ELISA measurement of TNF-α, IL-1β, and IL-6 protein levels following CSF3 overexpression (J) or knockdown (K) in CEF cells. (L) Western blot analysis of STAT3, phosphorylated STAT3 (p-STAT3), env, β-actin, IκBα, p-IκBα, p-p65, p52, and p100 after STAT3 phosphorylation inhibition in CSF3-overexpressing DF-1 cells. (M) Quantification of protein levels in (L) based on relative grayscale values. Statistical significance was determined using a two-tailed unpaired Student’s t-test ( p < 0.05). * p < 0.05, **p < 0.01, *** p < 0.001.
