Production of complex multiantennary N-glycans in Nicotiana benthamiana plants.
In recent years, plants have been developed as an alternative expression system to mammalian hosts for the production of therapeutic proteins. Many modifications to the plant glycosylation machinery have been made to render it more human because of the importance of glycosylation for functionality, serum half-life, and the safety profile of the expressed proteins. These modifications include re...
متن کاملMonoclonal Antibody Purification (Nicotiana benthamiana Plants).
Plant-based expression systems provide an alternative biomanufacturing platform for recombinant proteins (Matoba et al., 2011). In particular, plant virus-based vectors can overexpress proteins within days in the leaf tissue of Nicotiana benthamiana (N. benthamiana). To overcome the issues of genetic instability and limited infectivity of recombinant viruses, Agrobacterium-mediated delivery of ...
متن کاملEngineering of human-type O-glycosylation in Nicotiana benthamiana plants
Therapeutic properties of recombinant proteins are very often affected by the composition and heterogeneity of their glycans. Conventional expression systems for recombinant pharmaceutical proteins typically do not address this problem and produce a mixture of glycoforms that are neither identical to human glycans nor optimized for enhanced efficacy. In terms of glycosylation, plants offer cert...
متن کاملAntimicrobial Activity of Bacteriophage Endolysin Produced in Nicotiana benthamiana Plants.
The increasing spread of antibiotic-resistant pathogens has raised the interest in alternative antimicrobial treatments. In our study, the functionally active gram-negative bacterium bacteriophage CP933 endolysin was produced in Nicotiana benthamiana plants by a combination of transient expression and vacuole targeting strategies, and its antimicrobial activity was investigated. Expression of t...
متن کاملThe production of human glucocerebrosidase in glyco‐engineered Nicotiana benthamiana plants
For the production of therapeutic proteins in plants, the presence of β1,2-xylose and core α1,3-fucose on plants' N-glycan structures has been debated for their antigenic activity. In this study, RNA interference (RNAi) technology was used to down-regulate the endogenous N-acetylglucosaminyltransferase I (GNTI) expression in Nicotiana benthamiana. One glyco-engineered line (NbGNTI-RNAi) showed ...
