Mucosal Immunology

Mucosal immunology studies the immune system of the mucous membranes, which form the protective barrier between our bodies and the external environment. The mucosal surfaces, such as our gut, nose, and respiratory tract, are the interface between our body and the outside world, and are where most of our exposure to potential pathogens takes place. In addition to being the major portal of entry of pathogens, these mucosal surfaces are also home to a large number of microorganisms (known as the microbiome) that co-exist with us and play a key role in our health. By understanding the mechanisms and processes of mucosal immune defense and its interaction with the microbiome, new avenues of medical research are opening and helping in the development of treatments for numerous infectious and non-infectious diseases.
