Fig. 4From: The influence of hay steaming on clinical signs and airway immune response in severe asthmatic horsesRelative mRNA expression of cytokines in bronchoalveolar lavage fluid (BALF), before and after the initiation of each challenge: a interleukin (IL)-1β; b IL-18; c IL-6R; d IL-23. sEA, severe equine asthma; CTL, control; d-2, 2 days before challenge; d + 5, 5 days after challenge. Significant overall interactions (P < 0.05) were found between between ‘disease status’ (sEA, CTL) and ‘time’ (d-2, d + 5); the p-values correspond to the subsequent Tukey-Kramer’s post-hoc testsBack to article page
