[Specific features of centriole formation and ciliogenesis in ciliary epithelium cells of respiratory tracts in patients with Kartagener syndrome].
An electron microscopic study of the ciliary epithelium of respiratory tracts was carried out in children (members of the same family) with Kartagener syndrome, which is a variant of ciliary dyskinesia. It was shown that in the case of both mobile cilia and ciliary dyskinesia in man, centrioles are formed during formation of the ciliary basal bodies predominantly de novo, involving deuterosomes. A wide spectrum of pathological changes was described in literature, such as the absence of dynein arms in the axoneme and disorganization of axoneme structure. In addition to these changes in the ciliary system, we found integration of several ciliary axonemes by the same plasma membrane, running of microtubules from the plasma membrane as bundles, different orientation of basal legs, etc.
