Figure 5. Expression of IFN-α1 mRNA in TA-, TT-infected and control fish.

IFN-α1 mRNA expression in TA (A) and TT (B) infected, non-stressed and stressed fish is shown. IFNα-1 expression in uninfected fish after stress exposure is also shown (C). Stress down-regulates expression of IFN-α1 in infected fish and also in uninfected controls. P values are indicated, one-sided T-test (+SEM; n = 5 to 6 fish per group).
