Figure 5. EoE-relevant Th2 cytokines promote autophagic flux in oesophageal keratinocytes.
EPC2-hTERT cells were stimulated with 10 ng/ml IL-4, IL-5 and IL-13 in the presence or absence of 1 µg/ml CQ as indicated. (A) After 24 hours, immunoblot determined LC3-II and p62 (densitometry shown at bottom) with β-actin as a loading control. (B) After 72 hours, live cell imaging determined GFP-LC3 puncta with representative cell images (Left, Scale bar, 20 µm) and average GFP-LC3 puncta/cell (Right). *, p<0.05 vs. IL-13 (−) CQ (−); #, p<0.05 vs. IL-13 (+) CQ (−) and IL-13 (−) CQ (+); n=3.
