Fig 4. Influenza virus induces release of redoxins.

Western blot analysis following non-reducing (12% for PRDXs and 15% for TXN1) SDS-PAGE of A549 supernatants and cell lysates. A549 cells were infected with PR8 virus (+) or mock-infected (-) for 24 h as described in the Methods. Cell lysates were also analyzed after blocking with 40 mM NEM. B. IL-6 levels as measured by ELISA. Data are mean ± SE from three independent samples. *P<0.01 vs. non-infected cells by Student’s t-test.
