摘要:
The present invention relates to the discovery that non-traditional export of certain pro-inflammatory cytokines lacking a signal sequence from a cell can be inhibited by copper chelation and/or administration to the cell of a truncated form of S100A13 lacking the basic residue portion. Further, copper chelation inhibits, inter alia, neointima formation, macrophage infiltration and associated inflammation, cell proliferation, secretion of extracellular matrix, intimal thickening, adventitial angiogenesis, restenosis, and the like, associated with vascular vessel injury. Thus, the present invention provides novel methods of preventing and treating, and for identifying novel compounds also useful as therapeutics for, such conditions.
摘要:
Endothelial cell growth factor is achieved through the application of recombinant DNA technology to prepare cloning vehicles encoding the ECGF protein and procedures are disclosed for recovering ECGF protein essentially free of other proteins of human origin. The product is useful for, among other purposes, diagnostic applications and as potential in the treatment of damaged blood vessels or other endothelial cell-lined structures.
摘要:
This invention relates to therapeutic and diagnostic methods and compositions based on Jagged/Notch proteins and nucleic acids, and on the role of their signaling pathway in endothelial cell migration and/or differentiation. In addition, this invention provides a substantially purified Jagged protein, as well as a substantially purified nucleic acid molecule or segment thereof encoding Jagged protein, or a functionally equivalent derivative, or allelic or species variant thereof.
摘要:
The invention relates to the field of organ and tissue perfusion. More particularly, the present invention relates to a method for preparing organs, such as the kidney and liver, for cryopreservation through the introduction of vitrifiable concentrations of cryoprotectant into them. To prepare the organ for cryopreservation, the donor human or animal, is treated in the usual manner and may also be treated with iloprost, or other vasodilators, and/or transforming growth factor .beta.1. Alternatively, or additionally, the organ which is to be cryopreserved can be administered iloprost, or other vasodilators, and/or transforming growth factor .beta.1 directly into its artery. The invention also relates to preparing organs for transplantation by a method for the removal of the cryoprotectant therefrom using low (such as raffinose, sucrose, mannitol, etc.), medium (such as agents with intermediate molecular weights of around 600-2,000) and high (such as hydroxyethyl starch) molecular weight agents osmotic buffering agents. The invention is also directed to new post-transplantation treatments such as the use of transforming growth factor .beta.1, N-acetylcysteine and aurothioglucose. Further, the invention relates to a method of vitrification of organs comprising a multi-step method of introducing increasing concentrations of cryoprotectant with osmotic equilibration of the organ and decreases in temperature prior to perfusion with vitrifiable concentrations of cryoprotectant at about -5.degree. C. to -35.degree. C.
