“Chronic inflammation is uniformly damaging and is absolutely causal to the process, because if you interfere with it, you can reverse the pathology.” And this ability to control such diseases simply by reversing inflammation is a biological response, dating far back to the time of a common ancestor, that has been retained across diverse species of animals to the present day, he says, pointing to experimental evidence: “If you can make Drosophila [fruit fly] diabetic, and then block the inflammatory response systems, you can cure diabetes in Drosophila, the same way you can reverse it in the mouse, in primates, and in humans, provided that you do it with the right tools. Of course, the higher the organism, the more complex these pathways are, so it takes more effort to define the precise mechanisms to manipulate.” - harvardmagazine.com
