摘要:
The present invention provides a method for decreasing cerebral vasoconstriction in a subject suffering from chronic or acute cerebral amyloid angiopathy which comprises administering to the subject an inhibitor of receptor for advanced glycation endproduct (RAGE) in an effective amount to inhibit transcytosis of amyloid &bgr; peptides across the blood-brain barrier in the subject, thereby decreasing cerebral vasoconstriction in the subject. The invention further provides for a method for ameliorating neurovascular stress in a subject which comprises administering to the subject an effective amount of an inhibitor of receptor for advanced glycation endproduct (RAGE), so as to increase cerebral blood flow in the subject, thereby ameliorating neurovascular stress in the subject.

The present invention provides a method for treating inflammation in a subject which comprises administering to the subject soluble receptor for advanced glycation endproduct (sRAGE) in an amount effective to inhibit binding of advanced glycation endproducts (AGEs) to RAGE thereby treating inflammation in the subject. The present invention also provides for a method for treating inflammation in a subject which comprises administering to the subject an agent in an amount effective to inhibit the interaction between receptor for advanced glycation endproduct (RAGE) and its ligand thereby treating inflammation in the subject.

摘要:
This invention provides a method of inhibiting the binding of beta-sheet fibril to RAGE on the surface of a cell which comprises contacting the cell with a binding-inhibiting amount of a compound capable of inhibiting binding of beta-sheet fibril to RAGE so as to thereby inhibit binding of beta-sheet fibril to RAGE.In one embodiment, the beta-sheet fibril is amyloid fibril. In one embodiment, the compound is sRAGE or a fragment thereof. In another embodiment, the compound is an anti-RAGE antibody or portion thereof.This invention provides the above method wherein the inhibition of binding of the beta-sheet fibril to RAGE has the consequences of decreasing the load of beta-sheet fibril in the tissue, inhibiting fibril-induced programmed cell death, and inhibiting fibril-induced cell stress.This invention also provides methods of determining whether a compound inhibits binding of a beta-sheet fibril to RAGE on the surface of a cell.

摘要:
Disclosed are RAGE fusion proteins comprising RAGE polypeptide sequences linked to a second, non-RAGE polypeptide. The RAGE fusion protein may utilize a RAGE polypeptide domain comprising a RAGE ligand binding site and an interdomain linker directly linked to an immunoglobulin CH2 domain. Such fusion proteins may provide specific, high affinity binding to RAGE ligands. Also disclosed is the use of the RAGE fusion proteins as therapeutics for RAGE-mediated pathologies.
