    PIP 3 treatment of cells and integration in the plasma membrane are essential for phagocytic induction of nonmotile P. aeruginosa . (A) Murine WT BMDCs were assayed for relative phagocytosis of PA14 motAB motCD (MOI of 10) without or after treatment of bacteria (gray bar) or cells (white bar) with 12 μM PIP 3 . The data were normalized to phagocytosis of PA14 motAB motCD without PIP 3 treatment and are represented as fold increase in phagocytosis. (B) Phagocytic uptake of P. aeruginosa PA14 motAB motCD (MOI of 10) by murine WT BMDCs in the absence or presence of 12 μM inositol 1,3,4,5-tetrakisphosphate (IP 4 ). Phagocytic uptake was normalized as a percentage of the mean phagocytosis of motAB motCD bacteria in untreated cells. (C) The killing rate of PA14 WT and motAB motCD bacteria by BMDCs treated with PIP 3 was assayed by a gentamicin protection assay. Following a 45-min incubation of bacteria with BMDCs (MOI of 10), gentamicin was added, and at the indicated time points following gentamicin addition (20, 40, and 60 min), cells were lysed to assess remaining CFU counts. The number of CFU recovered was plotted relative to recovery at 20 min after gentamicin addition. All data were analyzed using one-way ANOVA with Tukey's post hoc analyses (A) or using an unpaired t test with Welch's correction (B) and are representative of at least two independent biological experiments ( n ≥8). ***, P ≤ 0.0005; *, P ≤ 0.05; ns, not significant, for results compared to those without PIP 3 treatment.
