The diverse features of the chemotaxis receptors and ligands allows for the possibility of selecting chemotactic responder cells with a simple chemotaxis assay By chemotactic selection, we can determine whether a still-uncharacterized molecule acts via the long- or the short-term receptor pathway. [64]
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 ...
Other chemotaxis assay techniques Besides the above-mentioned two most commonly used family of techniques, a wide range of protocols were developed to measure chemotactic activity. Some of them are only qualitative, like aggregation tests, where small pieces of agar or filters are placed onto a slide and accumulation of cells around is measured.
Second, medical roots generally go together according to language, i.e., Greek prefixes occur with Greek suffixes and Latin prefixes with Latin suffixes. Although international scientific vocabulary is not stringent about segregating combining forms of different languages, it is advisable when coining new words not to mix different lingual roots.
Chemotaxis is a response elicited by chemicals: that is, a response to a chemical concentration gradient. [8] [7] [13] For example, chemotaxis in response to a sugar gradient has been observed in motile bacteria such as E. coli. [14]
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. Term chemotactic selection is also used to design a technique which separates eukaryotic or prokaryotic cells upon their chemotactic responsiveness to selector ligands.

The mechanism of the chemorepulsion of immune cells was first acknowledged by medical researchers at the Massachusetts General Hospital in Boston in early 2002. [1] The phenomenon was originally referred to as "reverse chemotaxis ," and later, “fugetaxis” (derived from the Latin words fugere , to flee from; and taxis , movement). [ 1 ]
