Dynamics of Gradient Sensing and Chemotaxis

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

Chemotaxis, the ability of cells to sense external chemical gradients in order to direct movement is essential for the survival of all organisms, from bacteria and amoebae to humans. It requires the coordinated action of several processes, from the sensing of the external chemical to the interpretation of the gradient, to the steering of the cell's motion. Here we review a number of strategies used by cells that allow them to perform these various tasks successfully.
