Flow-induced bending of flagella restricts Pseudomonas aeruginosa surface departure [PDF]
mBioShear force associated with flow can bend, twist, or stretch cellular appendages. Bacterial appendages such as flagella can rotate and generate forces. However, it is unclear how environmental and cell-generated forces interact as bacteria associate with

The response regulator FpsR controls the flagella–pili transition and mucosal colonization in Ligilactobacillus ruminis [PDF]
Gut MicrobesLigilactobacillus ruminis is a flagellated lactic acid bacterium found in the intestines of various mammals, including humans. Although this species harbors a complete flagellar gene cluster, flagella formation has not been observed in human-derived ...

σ28-dependent small RNA regulation of flagella biosynthesis
eLife, 2023 Flagella are important for bacterial motility as well as for pathogenesis. Synthesis of these structures is energy intensive and, while extensive transcriptional regulation has been described, little is known about the posttranscriptional regulation ...

Synchronization, slippage, and unbundling of driven helical flagella. [PDF]
PLoS ONE, 2013 Peritrichous bacteria exploit bundles of helical flagella for propulsion and chemotaxis. Here, changes in the swimming direction (tumbling) are induced by a change of the rotational frequency of some flagella.

A role for the membrane in regulating Chlamydomonas flagellar length. [PDF]
PLoS ONE, 2013 Flagellar assembly requires coordination between the assembly of axonemal proteins and the assembly of the flagellar membrane and membrane proteins. Fully grown steady-state Chlamydomonas flagella release flagellar vesicles from their tips and failure to

Branchial cilia and sperm flagella recruit distinct axonemal components. [PDF]
PLoS ONE, 2015 Eukaryotic cilia and flagella have highly conserved 9 + 2 structures. They are functionally diverged to play cell-type-specific roles even in a multicellular organism.

Testing the ion-current model for flagellar length sensing and IFT regulation
eLife, 2023 Eukaryotic cilia and flagella are microtubule-based organelles whose relatively simple shape makes them ideal for investigating the fundamental question of organelle size regulation.

Flagella from five Cronobacter species induce pro-inflammatory cytokines in macrophage derivatives from human monocytes. [PDF]
PLoS ONE, 2012 Cronobacter spp. are opportunistic pathogens linked to lie-threatening infections in neonates and contaminated powdered infant formula that has been epidemiologically associated with these cases.

Flagellar Cooperativity and Collective Motion in Sperm
Fluids, 2021 Sperm have thin structures known as flagella whose motion must be regulated in order to reach the egg for fertilization. Large numbers of sperm are typically needed in this process and some species have sperm that exhibit collective or aggregate motion ...

Epithelial uptake of flagella initiates proinflammatory signaling. [PDF]
PLoS ONE, 2013 The airway epithelium serves multiple roles in the defense of the lung. Not only does it act as a physical barrier, it acts as a distal extension of the innate immune system.
