Patent number: 7713737Abstract: Methods and compositions for needleless delivery of macromolecules to the bloodstream of a subject are provided herein. In one aspect, the invention provides a delivery construct, comprising a receptor binding domain, a transcytosis domain, a macromolecule to be delivered to a subject, and a cleavable linker. In certain aspects, the cleavable linker can be cleavable by an enzyme present in higher concentration at or near the basal-lateral membrane of a polarized epithelial cell or in the plasma than elsewhere in the body, for example, at the apical side of the polarized epithelial cell. In other aspects, the invention provides nucleic acids encoding delivery constructs of the invention, kits comprising delivery constructs of the invention, cells expressing delivery constructs of the invention, and methods of using delivery constructs of the invention.Type: GrantFiled: October 4, 2005Date of Patent: May 11, 2010Assignee: Trinity Biosystems, Inc.Inventor: Randall J.
