  • Patent number: 8192951
    Abstract: An improved system for large scale production of proteins and/or polypeptides in cell culture is provided. In accordance with the present invention, cells expressing the protein or polypeptide of interest are grown in media that comprise a glycolysis-inhibiting substance. Additionally and/or alternatively, cells expressing the protein or polypeptide of interest are grown in media in which glutamine is limited. The use of such a system allows high levels of protein or polypeptide production and lessens accumulation of undesirable metabolic waste products such as lactate. Proteins and polypeptides expressed in accordance with the present invention may be advantageously used in the preparation of pharmaceutical, immunogenic, agricultural or other commercial compositions.

  • Patent number: 8173394
    Abstract: The invention relates to systems and methods for producing proteins of interest. The invention employs genetically-engineered animal or plant cells that have modified protein folding or processing capacities. In one aspect, the invention features genetically-engineered cells comprising one or more recombinant expression cassettes which encode (1) a protein of interest and (2) a polypeptide that is functional in the unfolded protein response (UPR) pathway of the cells. Co-expression of the polypeptide significantly increases the yield of the protein of interest in the genetically-engineered cells. In one example, the genetically-engineered cells are animal cells, and the co-expressed polypeptide is a component or modulator of an XB1- or ATF6-mediated UPR pathway.

  • Patent number: 8168397
    Abstract: The present invention relates to methods for the control of virulence of infectious bacteria by modulating the extra-cellular concentration of bacterial cell signalling molecules. Derivatives of cell signalling molecules are conjugated to suitable carrier proteins and used to isolate high affinity receptors recognizing the native signal molecule(s). By binding to signalling molecules, the receptors reduce and maintain extra-cellular concentrations of signal molecules below the threshold level that would otherwise result in certain opportunistic pathogens adopting a virulent form, and can transform virulent organisms to non-virulent states. These receptors have applications for the treatment of individuals with susceptibility to infection, the treatment of patients with existing infections, in disease monitoring and management, and in related applications where the host for infection is an animal or plant.

  • Patent number: 8129145
    Abstract: An improved system for large scale production of glycoproteins in cell culture is provided. In accordance with the present invention, cells expressing a glycoprotein are grown in media that contain manganese at a concentration of between approximately 10 and 600 nM. The use of such a system allows production of a glycoprotein with an increased glycosylation pattern and/or a glycosylation pattern that more accurately reflects the glycosylation pattern of the naturally occurring glycoprotein. A glycoprotein expressed in accordance with the present invention may be advantageously used in the preparation of pharmaceutical compositions.
