The significance of ultrastructural abnormalities of human cilia

B Fox, TB Bull, AR Makey and R Rawbone

The electronmicroscopic structure of cilia was studied from the inferior turbinate of the nose in 22 adults, and in 84 biopsies from the bronchial tree of 40 adults. The incidence of compound cilia and abnormal microtubular structures was assessed. There were significant variations in the incidence of abnormalities in different parts of the airways and even within different areas of the same electronmicroscopic section. The focal nature of differences in structure of cilia indicate that abnormalities found in a single biopsy do not necessarily reflect a generalized change in the bronchial tree. Thus, such a finding should not be used as evidence that the abnormalities of cilia are the cause of decrease in mucociliary clearance or that they play a role in the pathogenesis of bronchiectasis and sinusitis.
