Chemorepulsion - Wikipedia

WebChemoattraction and chemorepulsion are complex directional responses of a cell to external chemotactic stimuli. The decision of a cell to move towards or away from a chemokinetic source includes detection and quantitation of the gradient of the chemotactic agent, biochemical transmission of the stimulus, and translation into a directional migration. The chemorepulsion of immune cells was first postulated a priori based on the established migratory behavior of cells evidenced in several naturally occurring physiological processes: the development of the Central Nervous System, the establishment of immune-privileged sites, and thymic emigration. During the development of the Central Nervous System, chemokinetic agents influence the local… Webtoward an extrinsic chemokinetic factor, loss of adhesion, or fluid dynamics could not explain our observations, we postulated that mature T-cell emigration occurred as a result of the active movement of immune cells away from (fugetaxis) an intrinsic thymic stromal chemokinetic agent or agents generated from within the thymic organoid. property for sale near helotes tx
