Vesicles fall for traps
Hydin fl ips flagella H ydin is hiding no longer. On page 473, Lechtreck and Witman locate this protein to the buried central pair (CP) of fl agellar microtubules. The paralysis of cilia lacking hydin might be a basis for hydrocephalus-inducing brain fl uid accumulation. Flagella contain lots of hydin, but no one had yet localized the protein in any system. Lechtreck and Witman have now spotted...
متن کاملThe novel antibiotic rhodomyrtone traps membrane proteins in vesicles with increased fluidity
The acylphloroglucinol rhodomyrtone is a promising new antibiotic isolated from the rose myrtle Rhodomyrtus tomentosa, a plant used in Asian traditional medicine. While many studies have demonstrated its antibacterial potential in a variety of clinical applications, very little is known about the mechanism of action of rhodomyrtone. Preceding studies have been focused on intracellular targets, ...
متن کاملVirtual potentials for feedback traps.
The recently developed feedback trap can be used to create arbitrary virtual potentials, to explore the dynamics of small particles or large molecules in complex situations. Experimentally, feedback traps introduce several finite time scales: There is a delay between the measurement of a particle's position and the feedback response, the feedback response is applied for a finite update time, an...
متن کاملDielectrophoretic Traps for Cell Manipulation
One of the goals of biology for the next fifty years is to understand how cells work. This fundamentally requires a diverse set of approaches for performing measurements on cells in order to extract information from them. Manipulating the physical location and organization of cells or other biologically important particles is an important part in this endeavor. Apart from the fact that cell fun...
