  2. Chemotaxis - Wikipedia

    en.wikipedia.org/wiki/Chemotaxis

    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 ...

  3. Chemotaxis assay - Wikipedia

    en.wikipedia.org/wiki/Chemotaxis_assay

    Radial arrangement of PP-technique (3 or more channels) provides the possibility to compare chemotactic activity of different cell populations or study preference between ligands. [ 1 ] Counting of cells: positive responder cells could be counted from the front of migrating cells, after staining or in native conditions in light microscope.

  4. Chemotactic selection - Wikipedia

    en.wikipedia.org/wiki/Chemotactic_selection

    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.

  5. Chemokine - Wikipedia

    en.wikipedia.org/wiki/Chemokine

    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.

  6. Chemotactic drug-targeting - Wikipedia

    en.wikipedia.org/wiki/Chemotactic_drug-targeting

    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 ...

  7. Interleukin 8 - Wikipedia

    en.wikipedia.org/wiki/Interleukin_8

    IL-8 is the primary cytokine involved in the recruitment of neutrophils to the site of damage or infection; in a process called chemotaxis.A number of variables are essential for the successful chemotaxis of neutrophils, including the increased expression of high affinity adhesion molecules to secure the neutrophil to the endothelium near the affected site (and is therefore not washed away ...

  8. Haptotaxis - Wikipedia

    en.wikipedia.org/wiki/Haptotaxis

    In cellular biology, haptotaxis (from Greek ἅπτω (hapto) 'touch, fasten' and τάξις (taxis) 'arrangement, order') is the directional motility or outgrowth of cells, e.g. in the case of axonal outgrowth, usually up a gradient of cellular adhesion sites or substrate-bound chemoattractants (the gradient of the chemoattractant being expressed or bound on a surface, in contrast to the ...

  9. Sperm chemotaxis - Wikipedia

    en.wikipedia.org/wiki/Sperm_chemotaxis

    Since the discovery of sperm attraction to the female gametes in ferns over a century ago, [1] sperm guidance in the form of sperm chemotaxis has been established in a large variety of species [2] Although sperm chemotaxis is prevalent throughout the Metazoa kingdom, from marine species with external fertilization such as sea urchins and corals, to humans, [2] [3] [4] much of the current ...
