The lungs also have their own distinct microbiota, though lower in number and diversity than the gut. The two-way communication hub between the gut and lungs, called the gut-lung axis, influences the immune status of both organs. Crosstalk occurs through chemical messengers that are produced directly by microorganisms and by the immune system responses that they trigger. These messengers travel via the blood and lymph to help regulate immune system function throughout the body. A healthy gut microbiota will produce chemical signals that suppress inflammation in the gut and body, while an impaired microbiota will produce signals that increase inflammation. Read more.
