Polymyxin B induces exocytosis of alveolar type II cells.

<p>Initial lyso tracker green fluorescence of alveolar type II cells 30 min after staining, comparing cells incubated with Polymyxin B (PxB) to controls (DMEM). The fluorescence in cells exposed to PxB decreases in a time-dependent manner, whereas it remains stable in controls. Bars are mean+SD, n = 14–16. *: p<0.01 vs. DMEM.
