IL17A and viral infectious disease: To confirm the inhibitory effect of Ad-IL-17AR:Fc, we demonstrated that the myocardial IL-17A protein was reduced significantly in Ad-IL-17AR:Fc- compared with Ad-null-treated mice on day 90 post viral infection (Fig. 1C and D); however, Ad-IL-17AR:Fc did not alter the IL-17A receptor expression in the heart (Fig. 1E and F).
