Fig 1. MP-induced M2 skewing of SHIP-/- BM progenitors requires IL-4 and basophils but not IL-3.

A) Western blots of MФs derived from BM for 6 days with M-CSF ± IL-3 (10 ng/mL) or MP (5%). B) Arginase activity of MФs from SHIP-/- BM derived for 6 days with 10 ng/mL M-CSF ± IL-3 (10 ng/mL) or MP (5%) with 2.5 μg/mL of either an irrelevant or IL-4-neutralizing Ab. Data (mean ± SD) are representative of 3 independent experiments performed in triplicate. * p < 0.05 compared to all other conditions. C) Western blot of SHIP-/- MФs from (B) probed for Ym1, using SHC as a loading control. Dashed lines indicate where irrelevant lanes have been cropped out. All lanes are part of the same time-exposed film on the same gel. D) Western blot of SHIP-/- basophil-depleted (DX5-) or basophils (DX5+) + DX5- BM derived with M-CSF ± MP (5%). E) Arginase activity of SHIP-/- MФs derived from BM for 6 days with M-CSF ± MP (5%) or IL-3 (10 ng/mL) ± neutralizing Ab to IL-3 (2.5 μg/mL) or IL-4 (2.5 μg/mL). F) Western blot of cells corresponding to panel (E). *** p < 0.001 compared to relevant control.
