Autophagy and inflammation in the corneas of corneal injury (CI) mice. (A) Representative high magnification TEM pictures showing autophagosomes with double membrane structure were formed in CI models. Scale bar: 500 and 100 nm. (B) Western blotting showing expressions of the autophagy marker proteins p62, Beclin-1, and LC3B. (C) Western blotting showing the expression of the AMPK-mTOR-ULK1 autophagy flux pathway proteins pAMPK, AMPK, pULK1, ULK1, pmTOR and mTOR. (D) Relative band densities of p62, Beclin-1, LC3BII/I, and the ratios of pAMPK/AMPK, pULK1/ULK1, and pmTOR/mTOR. (E) Quantitative PCR results for mRNA levels of the inflammatory cytokines TNF-α, IL-1β, IL-6, and CXCL-2. Data are shown as mean ± SD. *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001.
