Mammalian cells for producing a secreted protein

The invention relates to the field of cell culture technology. It concerns the knockdown, using RNA interference, or gene knockout, of activating transcription factor 6 beta (ATF6B), or the combination of ceramide synthase 2 (CERS2) and TBC1 domain family member 20 (TBC1D20) proteins, which play central roles in the cellular secretion pathway. This downregulation leads to improved secretion of biopharmaceutically relevant products produced in mammalian cells. The invention specifically relates to mammalian cells having enhanced secretion of a recombinant therapeutic protein compared to a control cell, a method of producing said mammalian cell, a method for the production of a recombinant secreted therapeutic protein and the use of said mammalian cell for increasing the yield of a recombinant secreted therapeutic protein.

Mesenchymal stem cells expressing anti-inflammatory cytokines and methods of use

Provided are compositions and methods for production of anti-inflammatory cytokines, growth factors, or chemokines. Provided are nucleic acids (e.g., expression vectors) that include an NFκB inflammation response element operably linked to a nucleotide sequence encoding an anti-inflammatory cytokine (e.g., IL-4). In some cases, the nucleic acid is an expression vector selected from: a linear expression vector, a circular expression vector, a plasmid, and a viral expression vector. Also provided are cells (e.g., mesenchymal stem cells—MSCs) comprising a nucleic acid that includes an NFκB inflammation response element operably linked to a nucleotide sequence encoding an anti-inflammatory cytokine. In some cases, the nucleic acid is integrated into the cell's genome. Also provided are methods for treating an individual having an inflammation-associated ailment, which can include administering an MSC to the individual, where the MSC includes an NFκB inflammation response element operably linked to a nucleotide sequence encoding an anti-inflammatory cytokine.
