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 ...

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.

A Proline-Rich Element in the Type III Secretion Protein FlhB Contributes to Flagellar Biogenesis in the Beta- and Gamma-Proteobacteria

Frontiers in Microbiology, 2020
Flagella are bacterial organelles of locomotion. Their biogenesis is highly coordinated in time and space and relies on a specialized flagellar type III secretion system (fT3SS) required for the assembly of the extracellular hook, rod, and filament parts

Gardiquimod Nanoemulsion Targets Cutaneous Leishmaniasis Lesions Reducing Systemic Toxicity and Parasite Burden

Advanced Healthcare Materials, EarlyView.
Nanoemulsion delivery of a TLR7 agonist enhances safety and promotes colocalization with Leishmania‐infected macrophages in skin lesions, enabling a ∼2‐log reduction in parasite burden. However, tissue‐level constraints and TLR‐driven regulatory feedback generate a mixed immune response that limits complete parasite clearance.
