People are daily exposed to various pollutants present in airborne pollution. Many epidemiological studies revealed the existence of an association between indoor air pollution (aldehydes, VOCs, …) and the respiratory disorders. To study a such relationship, it is important to have toxicological elements to clarify the impact of these pollutants on cellular or tissue targets. Development of new in vitro models to assess the impact of environmental pollutants on human health is necessary. The present study investigated the pertinence to use a reconstituted epithelium, a 3D-model close to the human respiratory epithelium, co-cultured with immune cells, to assess the impact of environmental pollutants, such as volatile organic compounds (VOC), on biological activity.
