Combining Runmu fengye tang preparation with hydroxysugar glycolic acid eye drops regulates Th17/Treg balance to treat dry eyes via inhibition of JAK2/STAT3 pathway
Abstract
Methods: A scopolamine-induced dry eye rabbit model was administrated with Runmu Fengliang tang (RMFS) and hypromellose 2910, dextran 70 and glycerol eye drops (HGA). Schirmer's I test (SIt), break-up time (BUT) and histopathologic examinations (H&E) were used to assess dry eye symptoms and lacrimal gland damage. Flow cytometry was used to determine the number of apoptotic cells and percentages of Th17 and Treg, while Western blot assay was used to evaluate the expression of proteins related to JAK2/STAT3 pathway.
Results: The combination of RMFS with HGA significantly increased tear secretion (p < 0.001), shortened tear break-up time (p < 0.001), repaired ocular surface damage and reduced apoptosis (p < 0.05) in the scopolamine-induced dry eye model in rabbits, compared with the single-administration group. In addition, it regulated the Th17/Treg-related cytokine balance and inhibited the JAK2/SATA3 pathway.
Conclusion: The combination of RMFS and HGA alleviate dry eye symptoms by inhibiting the JAK2/SATA3 pathway in model rabbits induced by scopolamine and this treatment could be a potential therapeutic strategy for the treatment of dry eye disease. Future studies should focus on clinical data collection to investigate the efficacy and safety of the combination.
