In this article, we describe a case of bilateral maxillary sinus mucoceles that featured an absence of one of the microtubule doublets in three of the outer doublets of the axoneme, thereby establishing a diagnosis of isolated ciliary dysfunction.
This process is carried out by the intraflagellar transport (IFT) which is a bidirectional transport system mediated by multiprotein complexes (known as IFT particles) along the axoneme [16, 17].

Since the distal centriole gave rise to the sperm axoneme during spermiogenesis, it is logical to suppose that the proximal centriole that is inherited by the embryo could cause aberrant mitosis as both are derived from the same mother centriole in spermatids.
The axoneme of flagellum (9+2 microtubules) and its plasma membrane was extended symmetrically into two ridges that were clearly observed in TEM (fig.4c).
The basis of the axoneme is located close to the acrosomal complex.

Genetic and biochemical studies in Chlamydomonas have revealed that a protein in the Chlamydomonas flagellar axoneme, radial spoke protein 3 (Rsp3), is an A-kinase anchoring protein (AKAP).
Of these, the loss of an axoneme in the sperm's tail (male) and the loss of cilia on hexacanths and tails on plerocercoids (larval) occur more than once.
In order to validate the CRISPR Cas9 toolkit in Leishmania donovani, we targeted PF16 gene, which encodes a central pair protein of the axoneme, essential for parasite motility.
