摘要:
Glycosyl phosphatidy linositol specific phospholipase D (GPI-PLD) proteins and their medical uses are disclosed, in particular in the treatment and diagnosis of diabetes and complications of diabetes such as insulin resistance, liver dysfunction, disorders involving pancreatectomies and conditions mediated by a product of an infectious organism which is capable of inhibiting GPI-PLD, such as septic shock. The present invention further relates to variant GPI-PLD polypeptides modified at the phosphorylation site at amino acids 689-692 of the mature human wild-type protein.
摘要:
The present invention relates to the use of GPI-PLD for the prevention and treatment of conditions characterised by atherosclerosis. In some embodiments, this process may be caused by a failure to produce GPI-PLD, for example type 1 diabetes, or deliver GPI-PLD, such as patients deficient in apolipoprotein-A1, or those patients with autoantibodies to either GPI-PLD or Apo-A1. In other embodiments, the atherosclerotic process may result from a loss in GPI-PLD activity, e.g. where there is a genetic modification of GPI-PLD either affecting its activity or delivery to a target tissue, thereby leading to the atherosclerotic process.
摘要:
This application discloses that inositolphosphoglycans (IPGs) can be obtained from basophils, eosinophils and mast cells and that allergen stimulation of these cells results in IPG release. It also shows that IPGs are second messengers for allergic stimulation as the addition of some types of purified IPGs to non-allergen stimulated cells resulted in histamine release or degranulation. Thus, IPG antagonists can be used for the treatment of conditions (especially allergy and asthma) mediated by the release of IPGs from mast cells, basophils or eosinophils. Preferred IPG antagonists include anti-IPG antibodies, inhibitors of the enzyme GPI-PLD and competitive antagonists.
