Matériel péricentriolaire

Le matériel péricentriolaire est le nuage de matériel amorphe qui entoure une paire de centrioles (centre organisateur des microtubules). Il est composé de protéines fibrogranulaires.

Dissecting centriole fate in C. elegans development

Nils Kalbfuss

The presence of centrioles is critical for fundamental cell and developmental processes, including polarity, migration and division. Although centrioles are present in most proliferating cells, they are thought to vanish after cell cycle exit in some diffe ...

Architecture of the centriole cartwheel‐containing region revealed by cryo‐electron tomography

Centrioles are evolutionarily conserved barrels of microtubule triplets that form the core of the centrosome and the base of the cilium. While the crucial role of the proximal region in centriole biogenesis has been well documented, its native architecture ...

A helical inner scaffold provides a structural basis for centriole cohesion

The ninefold radial arrangement of microtubule triplets (MTTs) is the hallmark of the centriole, a conserved organelle crucial for the formation of centrosomes and cilia. Although strong cohesion between MTTs is critical to resist forces applied by ciliary ...
