The purpose of the present study was to potential molecular mechanisms of SS.
METHODS: Immunohistochemical and immunofluorescence techniques reveal the targets and therapeutic approaches of SS.
RESULTS: We found through molecular biology techniques such as immunoblotting and immunoprecipitation that USP5 is a novel regulator of NLRP3 involvement in the pathological process of SS. USP5 was significantly downregulated in submandibular gland tissue of SS. Meanwhile, it was found that USP5 is a negative regulator of NLRP3 via ubiquitination NLRP3. In addition, SalvianolicacidB (SaB), a natural USP5 agonist, can alleviate ss by regulating the USP5/NLRP3 signaling pathway.
CONCLUSIONS: Therefore, this study provides a new mechanism for SS and also provides new therapeutic targets for treating SS.
