Abstract:
:The remarkable success of therapeutic applications of immunoglobulin G (IgG) in form of monoclonal antibodies and pooled immunoglobulin G preparations has directed attention to this class of glycoproteins. It is commonly appreciated that oligosaccharides attached to the Fc-region play a critical role in the biological activity of IgGs. Thus, glycosylation has been a focus of interest for many scientists and the biopharmaceutical industry and expression hosts have been engineered in order to optimize antibody products. In this review we focus on efforts towards a targeted manipulation of IgG-Fc N-glycans using non-mammalian expression hosts, i.e. yeast, insect cells and plants. Current achievements in generating human-like N-glycan structures will be presented and recent data on the molecular mechanisms that might explain how these potent drugs mediate in vivo activities will be discussed.

杂志文章,评审abstract::We have analyzed the effect of chlorpromazine (CPZ) on pure actin. We have found that CPZ quenches Trp-79 and Trp-86 fluorescence and, in agreement with an earlier report on conventional actin, inhibits actin polymerization, lowering the extent of polymerization. Moreover, novel polymerization data are presented indic...
