Abstract

L'invention concerne le développement de lignées cellulaires ayant des voies de glycosylation modifiées qui leur permettent de réaliser une séquence de réactions enzymatiques, qui imitent le traitement de glycoprotéines chez les êtres humains. Des protéines recombinantes exprimées dans ces hôtes synthétisés par génie génétique produisent des glycoprotéines davantage similaires, voire sensiblement identiques, à leurs homologues humains. Les eucaryotes inférieurs, qui produisent ordinairement des N-glycanes à teneur élevée en mannose, comprenant des champignons unicellulaires et multicellulaires, sont modifiés de façon à produire des O-glycanes ou autres structures parmi les voies de glycosylation humaine. Ceci est obtenu à l'aide d'une combinaison de synthèse par génie génétique et/ou sélection de souches qui n'expriment pas certaines enzymes créant les structures complexes indésirables caractéristiques des glycoprotéines fongiques, qui expriment des cellules exogènes sélectionnées soit pour avoir une activité optimale dans les conditions présentes dans les champignons où l'activité est désirée, soit qui sont dirigées vers un organelle où une activité optimale est obtenue, et des combinaisons de ceux-ci dans lesquelles l'eucaryote synthétisé par génie génétique exprime de multiples enzymes exogènes requises afin de produire des glycoprotéines “de type humain”.
