Oral inflammatory diseases, such as oral lichen planus, involve dysregulated signaling pathways that contribute to tissue damage and inflammation. The JAK/STAT signaling pathway is particularly relevant in these conditions, making it a potential target for therapeutic intervention. Current treatments primarily focus on symptomatic relief, underscoring the need for novel approaches that can selectively modulate inflammatory responses.
Data Highlights
MOE was found to reduce interferon-stimulated gene expression, including significant reductions in MX1/2, IFIT, OAS family members, STAT1/2, CXCL10, and GBP1. Notably, NF-κB-dependent CXCL8 expression remained unaffected, indicating a selective modulation of the signaling pathways involved.
Key Findings
MOE selectively attenuated interferon-associated signaling without broadly suppressing inflammation.
It reduced JAK2 activity and inhibited STAT1 phosphorylation and nuclear translocation.
MOE significantly decreased CXCL10 expression at both mRNA and protein levels.
Caffeic acid, a component of MOE, was identified as having activity in suppressing CXCL10 production.
MOE's effects occurred independently of reactive oxygen species modulation.
Clinical Implications
Further investigation into MOE and its components may enhance understanding of treatment strategies for conditions like oral lichen planus.
Conclusion
This study establishes MOE as a selective modulator of interferon-driven inflammatory responses in oral epithelial cells.
