The global stress response regulator oxyS in an adherent-invasive Escherichia coli strain attenuates experimental colitis

open access: yesGut Microbes
Crohn’s disease and ulcerative colitis in humans and experimental immune-mediated colitis in mice are likely due in part to overactive immune responses to resident intestinal bacteria, including certain strains of adherent-invasive Escherichia coli (E ...

Single-particle imaging reveals intraflagellar transport–independent transport and accumulation of EB1 in \u3cem\u3eChlamydomonas\u3c/em\u3e flagella [PDF]

open access: yes, 2016
The microtubule (MT) plus-end tracking protein EB1 is present at the tips of cilia and flagella; end-binding protein 1 (EB1) remains at the tip during flagellar shortening and in the absence of intraflagellar transport (IFT), the predominant protein ...

Modeling straight and circle swimmers via immersed boundary methods: from single swimmer to collective motion [PDF]

open access: yesarXiv
We propose a minimal model of microswimmer based on immersed boundary methods. We describe a swimmer (either pusher or puller) as a distribution of point forces, representing the swimmer's flagellum and body, with only the latter subjected to no-slip boundary conditions with respect to the surrounding fluid. In particular, our model swimmer consists of
