Stable Production of Lentiviral Vectors

The present invention provides new stable packaging cell lines and producer cell lines as well as methods to obtain them, and a new method to produce lentiviral vectors using such cell lines. New methods and packaging cell lines of the invention are generated using a baculo-AAV hybrid system for stable expression of structural and regulatory lentiviral proteins, such system comprising a baculoviral backbone containing an integration cassette flanked by AAV ITR, in combination with a plasmid encoding rep protein. This system allows to obtain a stable integration of the structural and regulatory HIV-1 proteins gag/pol and rev. The system allows to obtain a first intermediate including only the structural and regulatory HIV proteins gag/pol and rev, to be used as starting point to obtain stable packaging cell lines as well as producer cell lines.

Methods and compositions for modified factor IX fusion proteins

The present invention provides Factor IX fusion proteins with higher specific activity and a longer useful clotting function relative to wild type or non-modified Factor IX protein.

POINT-OF-CARE AND/OR PORTABLE PLATFORM FOR GENE THERAPY

A platform for ex vivo isolation, production, and formulation of genetically-modified cells is described. The platform utilizes a software-enabled point-of-care and/or portable device making gene therapy more widely available.

METHODS AND CONSTRUCTS FOR PRODUCTION OF LENTIVIRAL VECTOR
20210062220 · 2021-03-04 ·

The present disclosure relates to methods for producing lentiviral vector-producing cells. Specifically the methods utilize two plasmids, rather than four, to provide the required packaging elements and transfer vector to a cell, allowing for the production of a large number of lentiviral producer cells, including suspension-based cells, and the production of high amounts of lentivirus. These methods allow for the production of cells that can be later induced to produce lentivirus, and can be tailored to include a specific gene of interest.
