A new class of protein sensor links spirochete pleomorphism, persistence, and chemotaxis

open access: yesmBio, 2023
Pathogenic spirochetes can alter their morphologies and behaviors to infect and survive within their hosts. Previous reports demonstrate that the formation of the so-called “round bodies” and biofilms, and chemotaxis are involved in spirochete ...

The Novel Protein Cj0371 Inhibits Chemotaxis of Campylobacter jejuni

open access: yesFrontiers in Microbiology, 2018
cj0371 is a novel gene that is associated with Campylobacter jejuni virulence, and an isogenic mutant of cj0371 showed hyper chemotaxis and motility. Chemotactic motility is an important virulence factor and is involved in C.

A minimal model of metabolism-based chemotaxis. [PDF]

open access: yesPLoS Computational Biology, 2010
Since the pioneering work by Julius Adler in the 1960's, bacterial chemotaxis has been predominantly studied as metabolism-independent. All available simulation models of bacterial chemotaxis endorse this assumption.

Different migration patterns of sea urchin and mouse sperm revealed by a microfluidic chemotaxis device. [PDF]

open access: yesPLoS ONE, 2013
Chemotaxis refers to a process whereby cells move up or down a chemical gradient. Sperm chemotaxis is known to be a strategy exploited by marine invertebrates such as sea urchins to reach eggs efficiently in moving water.

THE CHEMOSUPPRESSION OF CHEMOTAXIS [PDF]

open access: yesThe Journal of Experimental Medicine, 1966
The effects of various drugs on chemotaxis of polymorphonuclear leukocytes (PMN's) in vitro and in vivo have been studied. Response of rabbit PMN's in vitro to the chemotactic factor of rabbit serum, consisting of an activated protein-protein complex of the fifth and sixth (and probably seventh) components of complement (C'), is suppressed by ...

Enhancer of zeste homolog 2 enhances the migration and chemotaxis of dental mesenchymal stem cells

open access: yesJournal of International Medical Research, 2020
Objective To investigate the function of enhancer of zeste homolog 2 (EZH2) in the migration and chemotaxis of human dental tissue-derived mesenchymal stem cells. Methods The expression of EZH2, C-X-C motif chemokine ligand 11 (CXCL11), CXCL16, and CXCR1

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Mechanisms involved in human eosinophil chemotaxis induced by the newly cloned C-C chemokine eotaxin

open access: yesAllergology International, 1998
The present study was performed in order to investigate the mechanism(s) involved in eotaxin-induced normal human eosinophil chemotaxis using a 48-well micro-chemotaxis chamber assay.

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Counterclockwise rotation of the flagellum promotes biofilm initiation in Helicobacter pylori

open access: yesmBio
Motility promotes biofilm initiation during the early steps of this process: microbial surface association and attachment. Motility is controlled in part by chemotaxis signaling, so it seems reasonable that chemotaxis may also affect biofilm formation ...
