From: Legionella pneumophila induces human beta Defensin-3 in pulmonary cells
The type II and IVB secretion systems ofL. pneumophilaare not essential for hBD-3 release in A549 cells. A549 cells were infected with (A) L. pneumophila JR32, JR32ΔdotA, and (B) Corby as well as CorbyΔlspDE for 24 h. hBD-3 release was analyzed by ELISA. ELISA data presented are means ± SEM of four separate experiments. *, p < 0.05 compared with uninfected control cells.
