摘要

AIM: To study the inhibition effect of TAK-242 on the proliferation of rat eye Tenon's capsule fibroblasts via the toll-like receptor 4(TLR4) signaling pathway.METHODS: SD rat Tenon's capsule fibroblasts were extracted and cultured, then the cells were divided into normal control group, lipopolysaccharide(LPS) group(10 g/m L LPS) and TAK-242 group(1 μmol/L TAK-242, and 10 μg/m L LPS after 30 min). The expressions of TLR4, transforming growth factor-β1(TGF-β1) and interleukin-6(IL-6) in each group were detected by Western blot and reverse transcriptase-polymerase chain reaction(RT-PCR). Cell proliferation was detected by cell counting kit-8(CCK-8).RESULTS: Double immunofluorescent labeling in the extracted cells showed negative keratin staining and positive vimentin staining. Western blot showed that the LPS group had the highest expression of TLR4 and TGF-β1(P<0.01). Enzyme linked immunosorbent assay(ELISA) also showed that the secretion of IL-6 was the highest in LPS group(P<0.01). But there was no significant difference in TLR4 and TGF-1, as well as IL-6 expressions between the TAK-242 group and the normal control group(P>0.05). RT-PCR showed that the IL-6 m RNA expression in LPS group was the highest in the three groups(P<0.01). CONCLUSION: TAK-242 inhibits the proliferation of LPSinduced Tenon's capsule fibroblasts and the release of inflammatory factors by regulating the TLR4 signalingpathway, providing a new idea for reducing the scarring of the filter passage after glaucoma filtration surgery.
