Quarters were infused with 25 µg ovalbumin at time 0 and milk samples taken at indicated times. Median values (Q1, Q3) are shown. Concentrations varied significantly (Friedman test) as a function of hpi for C5a, CXCL8, IL-1β, IL-6, IFN-γ, IL-17A (p

Article Title: Comparison of innate immune agonists for induction of tracheal antimicrobial peptide gene expression in tracheal epithelial cells of cattle

doi: 10.1186/s13567-014-0105-8

Figure Lengend Snippet: Effects of CpG oligodinucleotide, interleukin-17A and interferon-α on tracheal antimicrobial peptide gene expression. Dose- and time-dependent effects were measured for CpG oligodinucleotide (A,B) , a TLR9 agonist; interleukin-17A (C,D) ; and interferon-α (E,F) . For the dose–response studies (A,C,E) , confluent bTEC were stimulated in triplicate with various concentrations of agonist for 16 h. For the time-course studies (B,D,F) , confluent bTEC were stimulated in triplicate for 4, 8, 16 or 24 h with the doses of agonist shown. Gene expression of TAP relative to that of GAPDH was measured using real-time RT-qPCR. Lipopolysaccharide (LPS, 0.1 μg/mL) was used in all assays as a positive control and standard. *, significantly different from unstimulated cells ( P

Figure Lengend Snippet: Comparison of the effects of IL-17A, Pam3CSK4 and LPS on tracheal antimicrobial peptide gene expression. Confluent cultures of tracheal epithelial cells from 4 different calves were non-stimulated (NS) or stimulated with 1 μg/mL Pam3CSK4, 316 ng/mL IL-17A, or 0.1 μg/mL LPS for 8 h (A) and 16 h (B) in triplicate. Gene expression was assessed using real-time RT-qPCR. Pam3CSK4 induced significantly higher tracheal antimicrobial peptide gene expression than IL-17A and LPS at both 8 and 16 h ( P

Figure Lengend Snippet: Effect of stimulation with single agonists compared to combined agonists. Cultured bovine tracheal epithelial cells were stimulated for 16 h in triplicate with various combinations of 1 μg/mL Pam3CSK4, 316 ng/mL IL-17A, or 0.1 μg/mL LPS. Tracheal antimicrobial peptide gene expression was measured as above. The effects of combined agonists were greater than that of interleukin-17A (IL-17A) alone, but minimally or not different than that of lipopolysaccharide (LPS) or Pam3CSK4 alone. The data shown (panels A, B and C) represent 3 studies conducted on different days using cells from different calves.
