Centriole Biogenesis: From Identifying the Characters to Understanding the Plot

Pierre Gönczy, Niccolo Banterle

The centriole is a beautiful microtubule-based organelle that is critical for the proper execution of many fundamental cellular processes, including polarity, motility, and division. Centriole biogenesis, the making of this miniature architectural wonder, ...

Zika virus (ZIKV) causes congenital microcephaly. Although ZIKV can impair cell cycle progression and provoke apoptosis, which probably contributes to disease aetiology through depletion of neural progenitor cells, additional cellular mechanisms may be imp ...

TRACMIT: An effective pipeline for tracking and analyzing cells on micropatterns through mitosis

Pierre Gönczy, Olivier Burri, Arne Seitz, Benita Wolf

The use of micropatterns has transformed investigations of dynamic biological processes by enabling the reproducible analysis of live cells using time-lapse fluorescence microscopy. With micropatterns, thousands of individual cells can be efficiently image ...

Centrioles are microtubule-based organelles found in most eukaryotic cells and that are critical for the formation of cilia and flagella, as well as of centrosomes in animal cells. The number of centrioles must be strictly regulated in proliferating cells ...

Dynein Transmits Polarized Actomyosin Cortical Flows to Promote Centrosome Separation

Pierre Gönczy, Alessandro De Simone

The two centrosomes present at the onset of mitosis must separate in a timely and accurate fashion to ensure proper bipolar spindle assembly. The minus-end-directed motor dynein plays a pivotal role in centrosome separation, but the underlying mechanisms r ...

Accurate spindle positioning is essential for error-free cell division. The one-cell Caenorhabditis elegans embryo has proven instrumental for dissecting mechanisms governing spindle positioning. Despite important progress, how the cortical forces that act ...

Centriolar CPAP/SAS-4 Imparts Slow Processive Microtubule Growth

Pierre Gönczy, Nicola Jane Dynes, Ashwani Sharma

Centrioles are fundamental and evolutionarily conserved microtubule-based organelles whose assembly is characterized by microtubule growth rates that are orders of magnitude slower than those of cytoplasmic microtubules. Several centriolar proteins can int ...

Basal body structure in Trichonympha

Pierre Gönczy, Paul Guichard

Trichonympha is a symbiotic flagellate of many species of termites and of the wood-feeding cockroach. Remarkably, this unicellular organism harbors up to over ten thousand flagella on its surface, which serve to propel it through the viscous environment of ...

The Human Centriolar Protein CEP135 Contains a Two-Stranded Coiled-Coil Domain Critical for Microtubule Binding

Pierre Gönczy, Georgios Hatzopoulos, Paul Guichard

Centrioles are microtubule-based structures that play important roles notably in cell division and cilium biogenesis. CEP135/Bld10p family members are evolutionarily conserved microtubule-binding proteins important for centriole formation. Here, we analyze ...

Computational support for a scaffolding mechanism of centriole assembly

Pierre Gönczy, Paul Guichard, Virginie Hamel

Centrioles are essential for forming cilia, flagella and centrosomes. Successful centriole assembly requires proteins of the SAS-6 family, which can form oligomeric ring structures with ninefold symmetry in vitro. While important progress has been made in ...
