摘要:
A process of producing a recombinant glycoprotein in a plant, in cells of a plant, or in plant cells is provided. The process comprises expressing in said plant, in cells of said plant or in said plant cells a nucleic acid sequence encoding a polypeptide having an N-glycosylation site and co-expressing a nucleic acid sequence encoding a heterologous single-subunit oligosaccharyltransferase.
摘要:
A process of producing a recombinant glycoprotein in a plant, in cells of a plant, or in plant cells, comprising expressing in said plant, in cells of said plant or in said plant cells a nucleic acid sequence encoding a polypeptide, said polypeptide having an N-glycosylation site of consensus sequence Asn-X-Ser or Asn-X-Thr, X being any standard amino acid residue, wherein, if the Asn residue of said N-glycosylation site is assigned amino acid sequence position 0, (a) the amino acid residue at position +3 is selected from Thr, Ser, Gly, Leu, Ile, Val and Met; or (b) the amino acid residue at position −1 is selected from Glu and Asp.
摘要:
The present invention is directed to a pharmaceutical composition including (eg for use as an adjuvant) a polymeric carrier cargo complex, comprising as a carrier a polymeric carrier formed by disulfide-crosslinked cationic components and as a cargo at least one nucleic acid (molecule) and at least one antigen associated with a tumour or cancer disease selected from; an idiotype immunoglobulin (e.g. an idiotype antibody or an idiotype B cell receptor); or at least one idiotype T cell receptor, or in each case a fragment, variant and/or derivative thereof. The inventive pharmaceutical composition allows for efficient induction of an adaptive immune response directed against the idiotype immunoglobulin or T cell receptor, particularly of a Th1-shiftet immune response. The present invention furthermore provides kits or kits of parts comprising the components of the inventive pharmaceutical composition, as well as the use of the inventive pharmaceutical composition or the inventive kit as a vaccine, particularly in the therapy of a tumour or cancer disease such as lymphoma, particularly B cell or T cell lymphoma.

An immunogenic composition comprising at least one Norovirus antigen and at least one adjuvant which is at least one B subunit of an AB5 toxin such as cholera toxin subunit B (CTB) or the B subunit of heat-labile E. coli exotoxin LT (LTB).
摘要:
The invention provides methods for reducing the levels of alfa (1,3)-fucosylated N-glycans on glycoproteins produced in plants or plant cells. In addition, the invention provides alfa(1,3)-fucosyltransferase genes from Nicotiana benthamiana, and mutant N. benthamiana plants in which the levels of alfa(1,3)-fucosylated N-glycans are reduced.
