Flagellum couples cell shape to motility in Trypanosoma brucei
Proceedings of the National Academy of Sciences of the United States of America, 2018 Significance Trypanosoma brucei is a highly invasive pathogen capable of penetrating deeply into host tissues. To understand how flagellar motility facilitates cell penetration, we used cryo-electron tomography (cryo-ET) to visualize two genetically ...

Sperm design and variation in the New World blackbirds (Icteridae) [PDF]
, 2009 Post-copulatory sexual selection (PCSS) is thought to be one of the evolutionary forces responsible for the rapid and divergent evolution of sperm design. However, whereas in some taxa particular sperm traits are positively associated with PCSS, in other

Effects of antibodies against dynein and tubulin on the stiffness of flagellar axonemes [PDF]
, 1981 Antidynein antibodies, previously shown to inhibit flagellar oscillation and active sliding of axonemal microtubules, increase the bending resistance of axonemes measured under relaxing conditions, but not the bending resistance of axonemes measured ...

The Vibrio H-Ring Facilitates the Outer Membrane Penetration of the Polar Sheathed Flagellum
bioRxiv, 2018 Flagellum is the major organelle for motility in many bacterial species. While most bacteria possess external flagella, such as the multiple peritrichous flagella found in Escherichia coli and Salmonella enterica or the single polar sheathed flagellum in

Trypanosoma brucei metacaspase 4 is a pseudopeptidase and a virulence factor [PDF]
, 2011 Metacaspases are caspase family cysteine peptidases found in plants, fungi, and protozoa but not mammals. Trypanosoma brucei is unusual in having five metacaspases (MCA1-MCA5), of which MCA1 and MCA4 have active site substitutions, making them possible ...

Microtubule sliding in swimming sperm flagella: direct and indirect measurements on sea urchin and tunicate spermatozoa [PDF]
, 1991 Direct measurements of microtubule sliding in the flagella of actively swimming, demembranated, spermatozoa have been made using submicron diameter gold beads as markers on the exposed outer doublet microtubules.
