Computational Study of Micropropulsion Mechanism in Water Modeled on Flagellum with Projecting Mastigonemes

Journal of Biomechanical Science and Engineering, 2009
The application of dynamics in organisms to the field of engineering is very instructive. From this point of view, we aimed at examining the micropropulsion mechanism modeled on aquatic microorganisms, and proposed a micropropulsion mechanism modeled on ...

Flagellar membrane association via interaction with lipid rafts [PDF]

, 2009
The eukaryotic flagellar membrane has a distinct composition from other domains of the plasmalemma. Our work shows that the specialized composition of the trypanosome flagellar membrane reflects increased concentrations of sterols and saturated fatty ...

Structural basis of directional switching by the bacterial flagellum

Nature Microbiology
The bacterial flagellum is a macromolecular protein complex that harvests energy from uni-directional ion flow across the inner membrane to power bacterial swimming via rotation of the flagellar filament.

Kinesin-8B controls basal body function and flagellum formation and is key to malaria transmission

Life Science Alliance, 2019
This comprehensive study describes the key role and real-time dynamics of Plasmodium kinesin-8B in microtubule-based basal body and axoneme assembly during flagellum (male gamete) formation and parasite transmission.

The Role of the Flagellar Protein FlgJ in the Virulence of Brucella abortus

Frontiers in Cellular and Infection Microbiology, 2020
Brucella abortus is a facultative intracellular pathogen that causes a zoonosis called brucellosis. This disease leads to abortion and infertility in cattle, and diverse complications in humans. B. abortus is a successful intracellular bacterium that has

The Unicellular, Parasitic Fungi, Sanchytriomycota, Possess a DNA Sequence Possibly Encoding a Long Tubulin Polymerization Promoting Protein (TPPP) but Not a Fungal-Type One

Microorganisms, 2023
The unicellular, parasitic fungi of the phylum Sanchytriomycota (sanchytrids) were discovered a few years ago. These unusual chytrid-like fungi parasitize algae.

Flagellum-deficient Pseudomonas aeruginosa is more virulent than non-motile but flagellated mutants in a cystic fibrosis mouse model

Microbiology Spectrum
Loss of the flagellum marks the pathoadaptation of Pseudomonas aeruginosa to the cystic fibrosis (CF) airway environment during lung disease. Losing the flagellum is advantageous to the bacterium as the flagellum can be recognized by immune cells.

In-phase and anti-phase flagellar synchronization by waveform compliance and basal coupling

New Journal of Physics, 2017
We present a theory of flagellar synchronization in the green alga Chlamydomonas , using full treatment of flagellar hydrodynamics and measured beat patterns.

The GTPase IFT27 is involved in both anterograde and retrograde intraflagellar transport

eLife, 2014
The construction of cilia and flagella depends on intraflagellar transport (IFT), the bidirectional movement of two protein complexes (IFT-A and IFT-B) driven by specific kinesin and dynein motors.
