We have a lot to learn about 'diseases of the aging' 19 December 2006 Trevor Marshall, Autoimmunity Research Foundation In 2004 we described how the chronic inflammatory disease, sarcoidosis, is caused by a life-long accumulation of intra-phagocytic bacterial pathogens. We recently published an update, reporting that many chronic inflammatory diseases result from a similar pathogenesis. Our Phase 2 clinical trial has already been demonstrating recovery from some of the diseases of aging, particularly arthritis, osteopenia, and even diabetes.Interestingly, those patients who have recovered from terminal inflammatory conditions, such as sarcoidosis and rheumatoid arthritis, report that recovery feels like "being 20 years younger." We are also observing that the body has an amazing ability to regenerate after inflammatory damage which is currently considered to be 'permanent' (eg, fibrosis and peripheral neuropathy). Clearly we still have a lot to learn about the processes which society categorizes as 'aging'.Our research points towards Th1 inflammation, the innate immune response to intraphagocytic pathogens, as being the cause of so many "disease of the aging," ranging from atherosclerosis, cardiomyopathy and arthritis through to many neurological conditions, and even to dementia. We have shown much chronic inflammation results from the body's innate immune response, and we agree it seems likely that 'Inflammaging' may also result from this same pathogenesis. References:1.
