Evaluation of a multi-component mucoadhesive buccal patch: cytokine-associated inflammatory responses and tissue remodeling in experimental models
To investigate cytokine-associated inflammatory and fibrotic responses, specifically IL-6, TNF-α, and MMP-2, following treatment with a mucoadhesive buccal patch containing isotretinoin, bromelain, and limonene.
Key Findings:
LPS stimulation induced upregulation of IL-6, TNF-α, and MMP-2; treatment with the formulation reduced expression of these inflammatory markers and COX-2.
Altered IL-2 and TGF-β expression suggested modulation of immune regulatory and fibrosis-associated pathways.
In vivo treatment showed reduced collagen-associated staining, improved tissue architecture, and functional improvements in mouth opening.
Interpretation:
The findings provide preliminary observations on cytokine-associated responses under inflammatory and fibrotic conditions relevant to OSMF.
Limitations:
The in vitro model represented an acute inflammatory epithelial response and did not fully recapitulate the fibrotic pathology of OSMF, indicating a need for more comprehensive models.
Further studies are required to define underlying mechanisms and evaluate translational applicability, particularly in human subjects.
Conclusion:
The study highlights the potential of a mucoadhesive buccal patch in modulating inflammatory and fibrotic responses in OSMF, suggesting a novel therapeutic approach.
