Abstract

Official abstract text for this publication.

The present invention discloses a novel therapeutic axis NTPDase8 enzyme, P2Y6 and/or P2Y2 receptors, and provides methods, enzymes and/or antagonists for remedying inflammatory bowel diseases.

First claim

Opening claim text (preview).

What is claimed is: 1 - 23 . (canceled) 24 . A method for the treatment or prevention of a chronic inflammatory bowel disease in a mammal, the method comprising administering to said mammal an effective amount of a composition comprising a Nucleoside triphosphate diphosphohydrolase (NTPDase) enzyme, wherein the enzyme is selected from the group consisting of: NTPDase3 and NTPDase8. 25 . The method of claim 24 , wherein said NTPDase enzyme is in a concentration sufficient to decrease a concentration of nucleoside triphosphate or diphosphate in a colon lumen of said mammal. 26 . The method of claim 25 , wherein said nucleoside triphosphate or diphosphate is selected from the group consisting of UTP, UDP, ADP and ATP. 27 . The method of claim 25 , wherein said composition further comprises an inhibitor or antagonist of P2Y 6 receptor. 28 . The method of claim 25 , wherein said composition further comprises an inhibitor or antagonist of P2Y 2 receptor. 29 . The method of claim 25 , wherein the administering comprises administering orally, enterally or intrarectally. 30 - 42 . (canceled) 43 . The method according to claim 24 , wherein said inflammatory bowel disease is selected from the group consisting of Crohn's disease, ulcerative colitis and GI tract cancer. 44 - 49 . (canceled) 50 . The method according to claim 24 , wherein said enzyme is NTPDase8.
