Novel nano-SiRNA delivery system loaded with anti-ESR1 siRNA and its application as a cyclosporine drug carrier in dry eye caused by diabetes

Abstract

Dry eye is a relatively common clinical condition caused by abnormal fluid dynamics and tear quality, for which effective pharmacological treatment is lacking. In this study, a new nano-siRNA delivery system loaded with anti-ESR1 siRNA was designed and synthesized, and its effect in the treatment of dry eye was evaluated. The system significantly inhibited the NaCl-induced increase in inflammatory factors, thereby suppressing the inflammatory response. In addition, the system downregulated the expression level of MMP-9 and STRA6. This system could be developed as a drug for the treatment of diabetes-induced dry eye.
