Insights into flagellar function and mechanism from the squid-vibrio symbiosis

Stéphanie Kéren Cohen

Flagella are essential and multifunctional nanomachines that not only move symbionts towards their tissue colonization site, but also play multiple roles in communicating with the host. Thus, untangling the activities of flagella in reaching, interacting, ...

Pseudomonas aeruginosa orchestrates twitching motility by sequential control of type IV pili movements

Alexandre Louis André Persat, Lorenzo Anton-Louis Talà

Prokaryotes have the ability to walk on surfaces using type IV pili (TFP), a motility mechanism known as twitching(1,2). Molecular motors drive TFP extension and retraction, but whether and how these movements are coordinated is unknown(3). Here, we reveal ...

Motility as a tool to uncover mobility practices

Vincent Kaufmann, Guillaume Simon Joseph Drevon, Alexis Gumy, Eloi Antoine Maël Bernier

This paper investigate the causal relationships that exist between the motility, defined as the personal ability to be mobile (Kaufmann et al., 2015), and mobility behaviors. To do so, we use the first wave (2018) of the "national daily mobility panel" sur ...

Centriole assembly at a glance

Pierre Gönczy, Georgios Hatzopoulos

The centriole organelle consists of microtubules (MTs) that exhibit a striking 9-fold radial symmetry. Centrioles play fundamental roles across eukaryotes, notably in cell signaling, motility and division. In this Cell Science at a Glance article and accom ...

Identification of Chlamydomonas Central Core Centriolar Proteins Reveals a Role for Human WDR90 in Ciliogenesis

Pierre Gönczy, Romain Hamelin, Florence Armand, Coralie Busso, Paul Guichard, Virginie Hamel, Isabelle Fluckiger

Centrioles are evolutionarily conserved macromolecular structures that are fundamental to form cilia, flagella, and centrosomes. Centrioles are 9-fold symmetrical microtubule-based cylindrical barrels comprising three regions that can be clearly distinguis ...

Comparative effect of growth media on the monitoring of E. coli inactivation and regrowth after solar and photo-Fenton treatment

César Pulgarin, Stefanos Giannakis, Rosa Mosteo

This study intends to assess the cultivability of photo-treated Escherichia coil K-12 on media With different selectivity (PCA, LBA, T-7, T-7 + TTC, VRBA and MAC) and to establish optimal conditions for bacterial recuperation. For these purposes, immediate ...

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 ...

Soft micromachines with programmable motility and morphology

Mahmut Selman Sakar

Nature provides a wide range of inspiration for building mobile micromachines that can navigate through confined heterogenous environments and perform minimally invasive environmental and biomedical operations. For example, microstructures fabricated in th ...

Two Conserved Histone Demethylases Regulate Mitochondrial Stress-Induced Longevity

Johan Auwerx, Laurent Mouchiroud, Evan Graehl Williams, Virginija Jovaisaite

Across eukaryotic species, mild mitochondrial stress can have beneficial effects on the lifespan of organisms. Mitochondrial dysfunction activates an unfolded protein response (UPR(mt)), a stress signaling mechanism designed to ensure mitochondrial homeost ...

Flagellar membranes are rich in raft-forming phospholipids

Adrian Schmid

The observation that the membranes of flagella are enriched in sterols and sphingolipids has led to the hypothesis that flagella might be enriched in raft-forming lipids. However, a detailed lipidomic analysis of flagellar membranes is not available. Novel ...
