B1R inflammation imaging. After 1-day starvation, A549 cells were treated with 100 µg P. aeruginosa lysate for 4 h to induce inflammation. Cells were stained with 100 nM of FITC-conjugated Lys-[D-Phe⁸]des-Arg⁹-BK for 1 h at 37°C and analyzed with optical imaging. Differential interference contrast (DIC) microscope image of (A) normal and (C) inflamed cells. Fluorescence and DIC merged images of (B) normal and (D) inflamed cells.
