Figure 2

Influenza virus induces BAFF expression and mucosal IgA responses in the lung. Mice were infected with influenza virus and sacrificed on day 1, day 7 and day 14 after infection. (A) The relative mRNA levels of keratinocyte-derived chemokine (KC) in the lung, (B) the total leukocyte counts, (C) BAFF protein levels and (D) influenza-specific secretory IgA (S-IgA) levels in bronchoalveolar lavage (BAL) fluid are shown (n = 3–5 mice/group). CTRL, controls; #, not detected; *P < 0.05; **P < 0.01.
