Preliminary experimental studies have confirmed that RZL can not only downregulate the serum Th1/Th2 and IL-17 levels and regulate the balance of Th17/Treg cells in SS model mice but also increase the water intake and submandibular gland index of SS mice and improve the submandibular gland lymphocyte infiltration and other pathological changes of model mice [7–10]. This evidence concerns the gene IL17A and synovial sarcoma.
