Highly phosphomannosylated enzyme replacement therapy for GM2 gangliosidosis

Abstract

This lysosome-directed recombinant human enzyme drug derived from methylotrophic yeast has the high therapeutic potential to improve the motor dysfunction and quality of life of the lysosomal storage diseases (LSDs) patients with neurological manifestations. We emphasize the importance of neural cell surface M6P receptor as a delivery target of neural cell-directed enzyme replacement therapy (NCDERT) for neurodegenerative metabolic diseases.
