Fig. 4From: Forsythiaside A improves Influenza A virus infection through TLR7 signaling pathway in the lungs of miceInfluenza FM1 viral load in lung tissue. A Shows the viral titer in the lung tissue of WT mice and TLR7−/− mice (n = 3). B Shows the FM1 mRNA expression level of influenza virus in the lung tissue of WT mice and TLR7.−/− mice (n = 3). *P < 0.05, **P < 0.01, ***P < 0.001, NS = not significant, P > 0.05Back to article page
