The review looks at the growing evidence to suggest that losing our old friend helminth parasites, which used to live relatively harmlessly in our bodies, can cause ageing-associated inflammation. It raises the possibility that carefully controlled, restorative helminth treatments could prevent ageing and protect against diseases such as heart disease and dementia. A decline in exposure to commensal microbes and gut helminths in developed countries has been linked to increased prevalence of allergic and autoimmune inflammatory disorders - the so-called old friends hypothesis , explains author Bruce Zhang, Undergraduate Assistant at the UCL Institute of Healthy Ageing, London, UK. A further possibility is that this loss of old friend microbes and helminths increases the sterile, ageing-associated inflamma
