Title:
METHOD FOR INHIBITING THE INDUCTION OF CELL DEATH BY INHIBITING THE SYNTHESIS OR SECRETION OF AGE-ALBUMIN IN CELLS OF THE MONONUCLEAR PHAGOCYTE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2011/142545
Kind Code:
A3
Abstract:
The present invention relates to a method for inhibiting the induction of cell death by inhibiting the synthesis or secretion of AGE-albumin in cells of the mononuclear phagocyte system, to an AGE-albumin synthesis inhibitor, and to a pharmaceutical composition comprising the AGE-albumin synthesis inhibitor for preventing or treating degenerative disease and autoimmune disease. The AGE-albumin of the present invention is synthesized and secreted in human microglia or human macrophages in an Alzheimer's model, stroke model, Parkinson's disease model and rheumatoid arthritis model. The AGE-albumin synthesis and secretion are caused by oxidative stress. The expression of RAGE increases in first-order human neurons or cartilage cells to which AGE-albumin is administered, whereupon a MAPK signaling pathway is activated and the expression of Bax increases to induce an increase in calcium in mitochondria, thus finally inducing cell death. Therefore, the AGE-albumin synthesis inhibitor of the present invention can be valuably used in the diagnosis or treatment of degenerative diseases or autoimmune diseases such as Alzheimer's disease, strokes, Parkinson's disease, amyotrophic lateral sclerosis, rheumatoid arthritis, diabetic retinopathy, AIDS, aging, pulmonary fibrosis, spinal cord injuries, etc.
