Effects of antibodies against tubulin on the movement of reactivated sea urchin sperm flagella [PDF]

open access: yes, 1980
Antibodies binding to sea urchin flagellar outer-doublet tubulin have been isolated from rabbit sera by tubulin-affinity chromatography employing electrophoretically purified tubulin as the immobilized substrate.

Spirochete Flagella and Motility [PDF]

open access: yesBiomolecules, 2020
Spirochetes can be distinguished from other flagellated bacteria by their long, thin, spiral (or wavy) cell bodies and endoflagella that reside within the periplasmic space, designated as periplasmic flagella (PFs). Some members of the spirochetes are pathogenic, including the causative agents of syphilis, Lyme disease, swine dysentery, and ...

Bacterial Outer Membrane Vesicles in Potentiating Cancer Vaccines: Progress and Prospects

open access: yesAdvanced Science, EarlyView.
Bacterial outer membrane vesicles (OMVs) have emerged as versatile platforms for cancer vaccine development owing to their intrinsic immunostimulatory properties and high engineering flexibility. This review summarizes OMV biology, immune mechanisms, and engineering strategies that enhance vaccine efficacy, discusses key translational challenges, and ...

Length regulation of multiple flagella that self-assemble from a shared pool of components

open access: yeseLife, 2019
The single-celled green algae Chlamydomonas reinhardtii with its two flagella—microtubule-based structures of equal and constant lengths—is the canonical model organism for studying size control of organelles.

Effects of viscosity and ATP concentration on the movement of reactivated sea-urchin sperm flagella [PDF]

open access: yes, 1975
1. Spermatozoa from the sea urchin, Lytechinus pictus, can be demembranated with solutions containing Triton X-100 and 5mM-CaCl2 and reactivated in ATP solutions containing low concentrations (10^(−9)M) Of free Ca^(2+) ion to give symmetrical bending ...

Kinesin‐Induced Buckling Reveals the Limits of Microtubule Self‐Repair

open access: yesAdvanced Science, EarlyView.
This study shows that kinesin‐driven buckling induces extensive microtubule lattice damage that often exceeds intrinsic self‐repair and leads to filament failure. While curvature, motor motility, and force individually cause limited damage, their combination overwhelms repair.

Swimming ability and flagellar motility of sperm packets of the volvocine green alga Pleodorina starrii.

open access: yesPLoS ONE
Eukaryotic flagella collectively form metachronal waves that facilitate the ability to cause flow or swim. Among such flagellated and planktonic swimmers, large volvocine genera such as Eudorina, Pleodorina and Volvox form bundles of small male gametes ...

TTC26/DYF13 is an intraflagellar transport protein required for transport of motility-related proteins into flagella

open access: yeseLife, 2014
Cilia/flagella are assembled and maintained by the process of intraflagellar transport (IFT), a highly conserved mechanism involving more than 20 IFT proteins. However, the functions of individual IFT proteins are mostly unclear.

Modelling the Fluid Mechanics of Cilia and Flagella in Reproduction and Development

open access: yes, 2012
Cilia and flagella are actively bending slender organelles, performing functions such as motility, feeding and embryonic symmetry breaking. We review the mechanics of viscous-dominated microscale flow, including time-reversal symmetry, drag anisotropy of
