Mucociliary epithelia are composed of multiciliated, secretory and stem cells, and line various organs in vertebrates such as the respiratory tract. By means of mucociliary clearance, those epithelia provide a first line of defense against inhaled particles and pathogens. Mucociliary clearance relies on the correct composition of cell types, i.e. the proper balance of ciliated and secretory cells, and on their successful differentiation and function. A failure to generate and to maintain correct cell type composition and function results in impaired clearance and high risk to infections, such as in congenital diseases (e.g. ciliopathies) as well as in acquired diseases, including Asthma, Chronic Obstructive Pulmonary Disease (COPD) and Idiopathic Pulmonary Fibrosis (IPF). We study mucociliary epithelia in various species to gain insights into the signaling contribution to organ development, regeneration and disease, and into the remarkable plasticity of cell identity encountered in mucociliary maintenance, including trans-differentiation during homeostasis and pathogenic tissue remodeling.
