FTX increased M1 polarized KCs. a The primary KCs were ensured by immunofluorescence assay labeled F4/80. b The expression of FTX was measured using qRT-PCR. c The expression of iNOS, CD206 and Arg-1 mRNAs in KCs were measured by qRT-PCR. d The production of TNF-α and IL-10 in cell culture supernatant were detected using ELISA assay. **p < 0.01, ^##p < 0.01 and ^#p < 0.05
