MENK administration inhibited virus replication in mice challenged with influenza virus. A HA titers and B Relative virus mRNA. The viral titers of supernatants of homogenized lung were determined by HA test and virus level in the lungs of mice was quantified by qPCR on day 4 p.i. C The localization and expression of influenza virus NP protein in lung tissue. D Panel represents quantified data of influenza virus NP protein expression. The data represent the mean ± SD of three independent experiments (each performed with n = 6 mice). Scale bar: 100 μm. ★p < 0.05, ★★p < 0.01, ★★★p < 0.001 versus the PR8 group
