Figure 5From: Differential modulation of cytokine, chemokine and Toll like receptor expression in chickens infected with classical and variant infectious bursal disease virusRelative gene expression at mRNA level, of innate cytokines mRNA in IBDV-infected bursa. At PIDs 3, 5 and 7, bursal mononuclear cells were isolated from cIBDV- or vIBDV-infected and virus-free control chickens and examined for (A) IFN-α and (B) IFN-β gene expression by qRT-PCR. Results are shown as transcription of the target gene relative to housekeeping gene 28S. The data are expressed as fold change expression in infected chickens over virus-free control. The values represent the mean ± SEM of 4 pools of 3 bursa each at designated PID. #Statistically significant differences between control and vIBDV- or cIBDV-infected groups (p < 0.05). *Statistically significant differences between vIBDV- and cIBDV-infected groups (p < 0.05).Back to article page
