chemoattractant

Examples

• All

• Bacterial cells move toward the chemoattractant in their environment to find nutrients.

• The presence of a chemoattractant generates extended movement in the favorable direction, such that the population as a whole moves toward the attractant.

• Bacterial cells swimming through an environment containing a chemoattractant experience noise both from within themselves and from the environment.

• Since the chemoattractant is present in this environment, external (or environmental) noise inevitably has an impact on ligand binding dynamics.

  Academic text (2012)

• Since that stochastic behavior occurs even for large gradients, it is not caused by noise (discussed above) associated with chemoattractant sensing.

  Academic text (2012)

• Whereas intracellular noise is present even without a chemical stimulus, the presence of a chemoattractant introduces an additional source of noise through the binding of the chemical ligand to the chemoreceptors.

• In many real situations, the chemoattractant in the extracellular environment is not static; it is also subject to fluctuations (Patnaik 2006a, 2007; Xu and Tao 2006).

  Academic text (2012)

• In addition, the chemoattractant ligand concentration itself fluctuates, as studied in the seminal work of Howard Berg and Edward Purcell on chemosensing in bacteria and as extended by others.

• One such example would be targeting the phenylacetic acid (PAA) catabolic pathway with selective inhibitors, as PAA functions as a potent chemoattractant for neutrophils.

• The phagocyte will be attracted to the chemoattractant released by the pathogen.
