Lanthionine synthetase component C-like proteins as molecular targets for preventing and treating diseases and disorders
The present invention relates to the field of medical treatments for diseases and disorders. More specifically, the present invention relates to the use of the lanthionine synthetase component C-like (LANCL) proteins as therapeutic targets for novel classes of anti-inflammatory, immune regulatory and antidiabetic drugs. This includes but it is not limited to abscisic acid (ABA), ABA analogs, benzimidazophenyls, repurposed drugs or drug combinations, including thiazolidinediones (TZDs); naturally occurring compounds such as conjugated diene fatty acids, conjugated triene fatty acids, isoprenoids, and natural and synthetic agonists of peroxisome proliferator-activated receptors that activate this receptor through an alternative mechanism of action involving LANCL2 or other membrane proteins to treat or prevent the common inflammatory pathogenesis underlying type 2 diabetes, atherosclerosis, cancer, some inflammatory infectious diseases such as influenza and autoimmune diseases including but not limited to inflammatory bowel disease (Crohn's disease and Ulcerative colitis), rheumatoid arthritis, multiple sclerosis and type 1 diabetes and other chronic inflammatory conditions.
1. A method for activating PPARγ in a cell comprising the step of contacting the cell with a compound effective to bind LANCL2, wherein the compound is NSC61610.
2. The method of claim 1 , wherein the compound increases the expression or activity of PPARγ.
3. The method of claim 1 , wherein the compound is part of a nutritional supplement, a nutraceutical, a functional food, or dietary aid.
4. The method of claim 1 , wherein the compound is also effective to suppress expression of an inflammatory molecule in cells or to suppress inflammatory cells.
5. The method of claim 4 , wherein the inflammatory molecule is tumor necrosis factor alpha or monocyte chemoattractant protein-1.
6. The method of claim 4 , wherein the inflammatory cells are inflammatory or M1 classically activated macrophage or other inflammatory phagocytes.
7. A method for treating inflammation, diabetes, or obesity comprising the steps of administering to an individual in need thereof a compound effective to bind LANCL2 and to activate PPARγ, wherein the compound is NSC61610 and wherein the inflammation is gastrointestinal tract inflammation, lung inflammation, or inflammation caused by influenza A or B virus, respiratory syncytial virus, Streptoeoecuspneumoniae, parainfluenza, rhinoviruses, Staphylococcus aureus, Francisella tularensis, Yersinia pestis, Bacillus anthraces, Mycobacterium tuberculosis.
8. The method of claim 7 , wherein the compound is part of a nutritional supplement, a nutraceutical, a functional food, or dietary aid.
9. The method of claim 7 , wherein the inflammation causes epithelial necrosis, airway infiltration with immune cells, mucosal and submucosal infiltration with immune cells and perivascular cuffing.
10. The method of claim 7 , wherein amount of the compound that is sufficient to alter the expression or activity of PPAR γ in a cell of the mammal is between about 0.5 mg/day and about 6,000 mg/day.
