Patents by Inventor Richard W. Welch

Richard W. Welch has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20100183640
    Abstract: The present invention provides methods and compositions to treat fibrotic conditions, to increase lymphocyte production in vivo, and to improve and/or normalize lung function, pulmonary compliance, blood oxygenation, and blood pH to inhibit inflammatory processes to stimulate or inhibit pro-inflammatory and immune cells, and to inhibit migration of vascular endothelial cells. The invention contemplates the administration of human uteroglobin, native or recombinant, as a means of achieving these ends. Specifically, it has been found that uteroglobin inhibits cell adhesion to fibronectin, increases lymphocyte production in vivo, and improves and/or normalizes lung function, pulmonary compliance, blood oxygenation, and blood pH, and inhibits inflammatory process. In addition it has been found that uteroglobin can stimulate or inhibit pro-inflammatory and immune cells and inhibitor migration of vascular endothelial cells.

  • Patent number: 7122344
    Abstract: The present invention relates generally to the production of recombinant human uteroglobin (rhUG) for use as a therapeutic in the treatment of inflammation and fibrotic diseases. More particularly, the invention provides processes, including broadly the steps of bacterial expression and protein purification, for the scaled-up production of rhUG according to current Good Manufacturing Practices (cGMP). The invention further provides analytical assays for evaluating the relative strength of in vivo biological activity of rhUG produced via the scaled-up cGMP processes.
