Figure 4. Maintenance of virus-specific Abs to influenza virus requires TACI.

Figure 4

(A) Sera from WT and TACI–/– mice were assayed for PR8-specific IgM and IgG by ELISA. Blood samples were collected from naive mice (n = 3 mice) and on days 8, 18, 33, and 60 p.i. (n = 3–12 mice per time point). (B) PR8-specific IgM, IgG, and IgA Ab titers in BAL were measured at days 8 and 32–34 p.i. (C) Total IgG and IgA in BAL from WT and TACI–/– mice (n = 8–11 mice/group) were determined (days 32–34 p.i.). Data with mean ± SEM are representative of at least 2 independent experiments. *P < 0.05, **P < 0.01, ***P < 0.001.
