This was originally published a couple of months ago. It fits in well with the infection theory: infection is common, but the disease depends on the body's response to it, and this response has a genetic component. You would expect it to vary according to different patterns of MHCs. Statins possibly work in two ways: they reduce the inflammatory response but they also inhibit Chl pneumoniae, but not stop it. It seems to me that pulses of minocycline are the only things at present which can do that, until a vaccine is developed.
