The invention relates to mRNA therapy for the treatment of Fabry disease. mRNAs for use in the invention, when administered in vivo, encode human the α-galactosidase A (GLA), isoforms thereof, functional fragments thereof, and fusion proteins comprising GLA. mRNAs of the invention are preferably encapsulated in lipid nanoparticles (LNPs) to effect efficient delivery to cells and/or tissues in subjects, when administered thereto. mRNA therapies of the invention increase and/or restore deficient levels of GLA expression and/or activity in subjects. mRNA therapies of the invention further decrease levels of toxic metabolites associated with deficient GLA activity in subjects, namely Gb3 and lyso-Gb3.
本发明涉及治疗法布里病的mRNA疗法。用于本发明的mRNA在体内给药时,编码人的α-半乳糖苷酶A(GLA)、其同工型、其功能片段和包含GLA的融合蛋白。本发明的mRNA优选封装在脂质纳米颗粒(LNPs)中,以便在给药时有效地传递到受试者的细胞和/或组织中。本发明的mRNA疗法可提高和/或恢复受试者体内不足的GLA表达和/或活性水平。本发明的mRNA疗法可进一步降低与受试者体内GLA活性不足有关的毒性代谢物,即Gb3和溶菌酶Gb3的水平。
