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 ...
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.
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.
Macrophage Inflammatory Proteins (MIP) belong to the family of chemotactic cytokines known as chemokines.In humans, there are two major forms, MIP-1α and MIP-1β, renamed CCL3 and CCL4 respectively, since 2000. [3]

CCL2 is a monomeric polypeptide, with a molecular weight of approximately 13-15 kDa depending on levels of glycosylation. [13] CCL2 is anchored in the plasma membrane of endothelial cells by glycosaminoglycan side chains of proteoglycans.
N-Formylmethionyl-leucyl-phenylalanine (fMLF, fMLP or N-formyl-met-leu-phe) is an N-formylated tripeptide and sometimes simply referred to as chemotactic peptide is a potent polymorphonuclear leukocyte (PMN) chemotactic factor and is also a macrophage activator. [2]
