Primary Institution: Duke University
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.
