摘要:
The invention relates to the discovery of novel soluble neutral active Hyaluronidase Glycoproteins (sHASEGPs), methods of manufacture, and their use to facilitate administration of other molecules or to alleviate glycosaminoglycan associated pathologies. Minimally active polypeptide domains of the soluble, neutral active sHASEGP domains are described that include asparagine-linked sugar moieties required for a functional neutral active hyaluronidase domain. Included are modified amino-terminal leader peptides that enhance secretion of sHASEGP. The invention further comprises sialated and pegylated forms of a recombinant sHASEGP to enhance stability and serum pharmacokinetics over naturally occurring slaughterhouse enzymes. Further described are suitable formulations of a substantially purified recombinant sHASEGP glycoprotein derived from a eukaryotic cell that generate the proper glycosylation required for its optimal activity.
摘要:
The invention relates to the discovery of a novel Chondroitinase Glycoproteins (CHASEGP's), methods of manufacture, and potential uses in conditions where removal of chondroitin sulfates may be of therapeutic benefit. Chondroitinase Glycoproteins require both a substantial portion of the catalytic domain of the CHASEGP polypeptide and asparagine-linked glycosylation for optimal chondroitinase activity. The invention also includes carboxy-terminal deletion variants of CHASEGP that result in secreted variants of the protein to facilitate manufacture of a recombinant CHASEGP. Further described are suitable formulations of a substantially purified recombinant CHASEGP glycoprotein derived from a eukaryotic cell that generate the proper glycosylation required for its optimal activity. CHASEGP is useful for the degradation of glycosaminoglycans and chondroitin sulfate proteoglycans under clinical conditions where their removal is of therapeutic value.

摘要:
Provided are modified matrix metalloprotease (MMP) enzymes that exhibit temperature-dependent activity and uses thereof. The MMPs can be used, for example, to treat ECM-mediated diseases or disorders characterized by increased deposition or accumulation of one or more ECM components.

This disclosure relates to a method of generating conditionally active biologic proteins from wild type proteins, in particular therapeutic proteins, which are reversibly or irreversibly inactivated at the wild type normal physiological conditions. For example, evolved proteins are virtually inactive at body temperature, but are active at lower temperatures.
摘要:
The identification of the HYAL1 hyaluronidase enzyme as a human plasma-derived myeloid colony-stimulating factor (CSF), herein designated CSF5-hyaluronidase, its recombinant production and methods of use are described. This protein may be used for the treatment of myelosuppression as may occur after irradiation, chemotherapy or other diseases where an increase in leukocyte levels may be beneficial. For example, CSF5- may be used to enhance the immune response to viral infection or other diseases associated with immune suppression.
摘要:
A synthetic resin article is provided for use in a fluid diversion system with one or more distribution lines. The article's frame has a top, at least one side, a bottom and an interior. At least one aperture is formed at the top. An intake port is disposed on at least one side of the frame, for engagement with the system distribution line. A drainage structure is disposed on the bottom of the frame for downward drainage of standing water into the surrounding soil or other environment. When the system delivers fluid through the distribution line, it is received in the interior of the frame and drains slowly out through the drainage structure but normally when the system delivers fluid to the interior at a sufficient rate, the fluid rises to the top of the frame and percolates out of the outlet aperture. In preferred embodiments, the top includes a plurality of small outlet gratings for additional percolation. In particularly preferred embodiments, the outlet gratings are formed as a plurality of slots for optimized percolation and diffusion.
