Chemotaxis of bio-hybrid multiple bacteria-driven microswimmers
Scientific Reports, 2016 In this study, in a bio-hybrid microswimmer system driven by multiple Serratia marcescens bacteria, we quantify the chemotactic drift of a large number of microswimmers towards L-serine and elucidate the associated collective chemotaxis behavior by ...

The Journal of Cell Biology, 2007 A cell polarity switch controls whether cells rush toward an attractive chemical or shift into reverse when they encounter something repulsive, according to Keizer-Gunnink et al. on page 579. They show that the status of phospholipase C (PLC) sets up the polarity axis for directional movement.

Sub-logistic source can prevent blow-up in the 2D minimal Keller-Segel chemotaxis system
, 2017 It is well-known that the Neumann initial-boundary value problem for the minimal-chemotaxis-logistic system in a 2D bounded smooth domain has no blow-up for any choice of parameters. Here, for a large class of kinetic terms including sub-logistic sources,

Advanced Materials, EarlyView.This study develops a multifunctional CRISPR‐dCas9‐based OMV platform termed OMV‐C9I12, which facilitates the coexpression of CXCL9 and IL‐12 within tumor cells. This platform enhances T cell recruitment and activation, synergizes with anti‐PD‐1/PD‐L1 immunotherapy, and amplifies antitumor T cell immunity.

Integration of the Second Messenger c-di-GMP into the Chemotactic Signaling Pathway
mBio, 2013 Elevated intracellular levels of the bacterial second messenger c-di-GMP are known to suppress motility and promote sessility. Bacterial chemotaxis guides motile cells in gradients of attractants and repellents over broad concentration ranges, thus ...
