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.
