Cholesterol synthesis is the trigger and isoprenoid dependent interleukin-6 mediated inflammation is the common causative factor and therapeutic target for atherosclerotic vascular disease and age-related disorders including osteoporosis and type 2 diabetes

This is a unifying theory that cholesterol metabolites (isoprenoids) are an integral component of the signaling pathway for interteukin-6 (IL-6) mediated inflammation. IL-6 inflammation is the common causative origin for atherosclerosis, peripheral vascular disease, coronary artery disease, and age-related disorders including osteoporosis, dementia, Alzheimer's disease and type 2 diabetes. Therapeutic effects of bisphosphonates and statins are mediated by isoprenoid depletion. Statins and bisphosphonates act in the chotesterol pathway to deplete isoprenoids. Anti-inflammatory properties of statins and bisphosphonates are due to isoprenoid depletion with subsequent inhibition of IL-6 mediated inflammation. Therapeutic targets for the prevention and control of all the above diseases should focus on cholesterol metabolites and IL-6 mediated inflammation. Prevention of atherosclerotic vascular disease and age-related disorders will be by utilization of cholesterol towering agents or techniques and/or treatment with statins and/or bisphosphonates to inhibit IL-6 inflammation through regulation of cholesterol metabolism.
