Hypothesis

The study investigates the relationship between TGF-β1 and IL-6 in human trabecular meshwork cells and the signaling pathways involved in IL-6 expression due to mechanical stress.

Conclusion

TGF-β1 regulates IL-6 expression in trabecular meshwork cells, suggesting an autocrine loop between IL-6 and TGF-β1.

Supporting Evidence

  • TGF-β1 treatment significantly increased IL-6 levels in trabecular meshwork cells.
  • Blocking the p38 MAPK pathway reduced IL-6 expression induced by TGF-β1.
  • Mechanical stress also increased IL-6 expression, which was inhibited by TGF-β1 pathway blockers.

Takeaway

This study shows that a protein called TGF-β1 helps control another protein called IL-6 in eye cells, which is important for eye pressure regulation.

Methodology

The study used ELISA to quantify IL-6 and PCR to evaluate IL-6 mRNA levels in human trabecular meshwork cells under mechanical stress.

Participant Demographics

Human trabecular meshwork cells from cadaver eyes aged 30-60.
