The Role of Sperm Centrioles in Human Reproduction – The Known and the Unknown
Frontiers in Cell and Developmental Biology, 2019 Each human spermatozoon contains two remodeled centrioles that it contributes to the zygote. There, the centrioles reconstitute a centrosome that assembles the sperm aster and participate in pronuclei migration and cleavage. Thus, centriole abnormalities

Acta Zoologica, EarlyView.ABSTRACT Marine gastrotrichs inhabit sediments with limited available light, yet evidence suggests that photoreceptor organs are present throughout the phylum Gastrotricha. Here, we confirm this proposition with ultrastructural descriptions of photoreceptive organs in two species of Xenotrichulidae (Order Chaetonotida) that lack pigmented ocelli ...

Two-step phosphorylation of Ana2 by Plk4 is required for the sequential loading of Ana2 and Sas6 to initiate procentriole formation. [PDF]
, 2017 The conserved process of centriole duplication requires Plk4 kinase to recruit and promote interactions between Sas6 and Sas5/Ana2/STIL (respective nomenclature of worms/flies/humans).

The Journal of Cell Biology, 1966 Sperm formation was studied in the fern, Marsilea, and the cycad, Zamia, with particular emphasis on the centrioles. In Marsilea, the mature sperm possesses over 100 flagella, the basal bodies of which have the typical cylindrical structure of centrioles. Earlier observations by light microscopy suggested that these centrioles arise by fragmentation of

Deuterosome-Mediated Centriole Biogenesis [PDF]
Developmental Cell, 2013 The ability of cells to faithfully duplicate their two centrioles once per cell cycle is critical for proper mitotic progression and chromosome segregation. Multiciliated cells represent an interesting variation of centriole duplication in that these cells generate greater than 100 centrioles, which form the basal bodies of their motile cilia.

Nature CommunicationsCentriole integrity, vital for cilia formation and chromosome segregation, is crucial for human health. The inner scaffold within the centriole lumen composed of the proteins POC1B, POC5 and FAM161A is key to this integrity.

The MacBrain Resource Center (MBRC) rhesus macaque embryonic brain histology datasets
Journal of Anatomy, EarlyView.We introduce the MacBrain Resource Center (MBRC) Collections of rhesus macaque embryonic brain tissue. Here, we illustrate histo‐ and immunohistology from our dynamically growing Collection 6, which currently contains >10,000 zoomable and downloadable images from n = 14 male and female embryos from early to late in gestation.

Centriole polarisation to the immunological synapse directs secretion from cytolytic cells of both the innate and adaptive immune systems [PDF]
, 2011 BACKGROUND: Cytolytic cells of the immune system destroy pathogen-infected cells by polarised exocytosis of secretory lysosomes containing the pore-forming protein perforin.

Towards understanding centriole elimination
Open Biology, 2023 Centrioles are microtubule-based structures crucial for forming flagella, cilia and centrosomes. Through these roles, centrioles are critical notably for proper cell motility, signalling and division. Recent years have advanced significantly our understanding of the mechanisms governing centriole assembly and architecture.
