Publication number: 20240093231Abstract: The present invention relates to the production of adeno-associated viral vectors in insect cells. The insect cells therefore comprise a first nucleotide sequence encoding the adeno-associated virus (AAV) capsid proteins, whereby the initiation codon for translation of the AAV VP1 capsid protein is an AUG. Upstream of the VP1 open reading frame an alternative out of frame start codon is placed such that translation initiation of the VP1 protein is modified, i.e. reduced, to allow production of VP1:VP2:VP3 in a good stoichiometry resulting in AAV with high potency.Type: ApplicationFiled: May 3, 2023Publication date: March 21, 2024Applicant: uniQure IP B.V.Inventors: David Johannes Francois Du Plessis, Olivier Ter Brake, Sebastiaan Menno Bosma, Harald Peter Albert Petry, Jacek Lubelski

Publication number: 20210353776Abstract: Upon administration of rAAV vectors the humoral immune response (neutralizing antibodies) is the first barrier that needs to be overcome. Surprisingly it was found that by using immunoadsorption for depletion of immunoglobulins from the blood (plasma), subjects can be highly efficiently treated with rAAV vectors, i.e. obtain highly efficient transduction after rAAV vector administration, in spite of the presence of high levels of nAb.Type: ApplicationFiled: June 3, 2021Publication date: November 18, 2021Applicant: uniQure IP B.V.Inventor: Valerie FERREIRA
