Publication number: 20130156703Abstract: The present invention provides a method of reducing the quanitity of mucus in the respiratory tract of a subject with elevated levels of mucus in said respiratory tract. The method includes administering to the subject a compound or composition containing a therapeutically effective amount of a fusion protein comprising a sialidase or an active portion thereof and an anchoring domain. The therapeutically effective amount comprises an amount of the fusion protein that results in a reduction of the quanitity of mucus in the respiratory tract after administration of the compound or composition when compared to the quantity of mucus present prior to administration of the compound or composition.Type: ApplicationFiled: February 15, 2013Publication date: June 20, 2013Inventors: Fang Fang, David Wurtman, Ron Moss, Michael Malakhov

Patent number: 8084036Abstract: The present invention provides new compositions and methods for preventing and treating pathogen infection. In particular, the present invention provides compounds having an anchoring domain that anchors the compound to the surface of a target cell, and a therapeutic domain that can act extracellularly to prevent infection of the target cell by a pathogen, such as a virus. Preferred target cells are epithelial cells. The invention provides compositions and methods for preventing viral diseases, such as influenza, using compounds having anchoring domains that can bind target cells linked to enzymatic activities that can act extracellularly to interfere with viral infection of target cells. The invention also provides compositions and methods for preventing viral diseases such as influenza using compounds having anchoring domains that can bind target cells linked to protease inhibitors that can act extracellularly to interfere with viral infection of target cells.Type: GrantFiled: November 21, 2003Date of Patent: December 27, 2011Assignee: NexBio, Inc.Inventors: Mang Yu, Fang Fang, Michael Malakhov
