Impaired C5/C5a production in PI3Kδ-/- mice. At 2–4 h following OVA/anti-OVA (IC) and anti-OVA (Ab) challenge in PI3Kγ-/- or PI3Kδ-/- mice or their WT controls, lungs were lavaged and assayed for cellular C5 mRNA expression by real-time RT-PCR (A and B), and C5a-mediated C5aR-triggered chemotactic activity of BALF was determined by Transwell migration assays of neutrophils (PMN isolated from bone marrow of C57BL/6 and C5aR-/- B6 mice) (C). Results are shown as the means ± S.E. (n = four to seven mice for each group). Significant differences were determined by Student's t test (*, p < 0.05; **, p < 0.001). AU, arbitrary units; n.d., not determined.
