RT Journal Article SR Electronic T1 Electron tomography of respiratory cilia JF Thorax JO Thorax FD BMJ Publishing Group Ltd and British Thoracic Society SP 190 OP 191 DO 10.1136/thoraxjnl-2012-202938 VO 68 IS 2 A1 Amelia Shoemark A1 Claire Hogg YR 2013 UL http://thorax.bmj.com/content/68/2/190.abstract AB Cilia are organelles present on almost every cell within the body. In the respiratory tract, motile cilia line the epithelial surface and beat in a coordinated fashion to clear mucus from the airways. Mucociliary dysfunction is implicated in a number of lung diseases including cystic fibrosis, chronic obstructive pulmonary disease, bronchiectasis and primary ciliary dyskinesia. Recent microscopy advances such as electron tomography have developed our understanding of the structure and function of these important organelles. In this review we discuss electron tomography and its relevance to respiratory cilia.
