Spatial ecology of soil microorganisms is a function of their chemotactic sensitivities towards substrate and fellow organisms. [74] [non-primary source needed] [non-primary source needed] The chemotactic behavior of the bacteria was proven to lead to non-trivial population patterns even in the absence of environmental heterogeneities. The ...
Within this medical field is a special reversal form of drug delivery called chemotactic drug targeting. [ 1 ] [ 2 ] By using chemical agents to help guide a drug carrier to a specific location within the body, this innovative approach seeks to improve precision and control during the drug delivery process, decrease the risk of toxicity, and ...
In general, the most important requisite is to calibrate the incubation time of the assay both to the model cell and the ligand to be evaluated. Too short incubation time results in no cells in the sample, while too long time perturbs the concentration gradients and measures more chemokinetic than chemotactic responses.
By chemotactic selection we can determine whether a still not characterized molecule acts via the long- or the short-term receptor pathway. Recent results proved that chemokines (e.g. IL-8 , RANTES ) are working on long-term chemotaxis receptors, while vasoactive peptides (e.g. endothelin ) act more on the short-term ones.
Chemokines (from Ancient Greek χῠμείᾱ (khumeíā) 'alchemy' and κῑ́νησῐς (kī́nēsis) 'movement'), or chemotactic cytokines, are a family of small cytokines or signaling proteins secreted by cells that induce directional movement of leukocytes, as well as other cell types, including endothelial and epithelial cells.
Here’s how to reduce the risk of infection by opting for some more hygienic interactions
“Unfortunately, this concept lacks a clear definition and is often misleading,” she says. While clean eating often means avoiding ultra-processed foods, there is a growing movement in the ...
Chemorepulsion is the directional movement of a cell away from a substance. Of the two directional varieties of chemotaxis, chemoattraction has been studied to a much greater extent.
