Fig. 5From: Polypropylene nanoplastic exposure leads to lung inflammation through p38-mediated NF-κB pathway due to mitochondrial damagea Representative images with 2.5 μg/ml of JC-1 dye for 30 min. Red (568 nm) staining was in J-aggregate form, whereas green (488 nm) staining was in monomer form. b Mitochondrial depolarization is indicated by a decrease in the red/green fluorescence intensity ratio. c ATP assay was measured in cell lysates of PP-exposed A549 cells. Data are means ± SD (n = 3 per group). #P ≤ 0.05; ###P ≤ 0.001 vs. VC. Scale bar 20 μmBack to article page
