Why do we need to have a good complement of gut microbes? Besides the usual concerns that you hear about, this one will surprise you: some lung problems are now found to be tied to disrupted gut flora. A group of researchers have begun to elucidate how this may occur... Reactive oxygen molecules are highly toxic molecules produced by our immune systems to kill bacteria and help protect against infection, but they can also cause collateral damage to our tissues, says Clarke. This means their production must be tightly regulated, in order to kill bacteria without doing major damage to lung tissue. This work shows that signals from commensal bacteria [in the gut] are part of this regulation and help establish the appropriate level of immune activation, says Clarke. medicalxpress/news/2014-09-commensal-bacteria-orchestrate-immune-response.html
