The Gut-Lung Axis
Airway and lung microbiota
There is a diverse population of microbes found throughout the upper respiratory tract and lower respiratory tract. These have been shown to interact with immune functions.
Recent evidence describes the cross-talk between the microbiotas of the gut and lungs. Changes in lung microbial community influence the composition of gut microbiota and viceversa, influencing respiratory health.
Disruptions in gut and lung microbiota have been linked to respiratory diseases including viral respiratory tract infections, asthma, chronic obstructive pulmonary disease (COPD) and lung cancer.
Gut microbiota regulates the immune system and protects against harmful pathogens. As we grow, microbiota and immune system shape the development of each other.
