31. Chemotaxis is the process by which phagocytes follow the cytokine " scent " to the infected spot.32. CCL11 selectively recruits eosinophils by inducing their chemotaxis , and therefore, is implicated in allergic responses. 33. During infection, macrophages release cytokines which trigger neutrophils to seek the site of infection by chemotaxis . 34. This type of molecular communication can also be achieved by using E . coli bacteria as chemotaxis . 35. These biorobots can be directly controlled by stimuli such as chemotaxis or galvanotaxis with several control schemes available. 36. As this is occurring, amoebae have been undergoing cAMP-induced chemotaxis towards the giant cell surface. 37. This protein is methyl-accepting chemotaxis protein ( MCP ) and it acquires methyl groups from methionine. 38. In some species ( for example, herring or the ascidian Ciona ) activation of motility precedes chemotaxis . 39. It has been shown that adult females cannot locate the host at a distance via rheotaxis or chemotaxis . 40. By the 1980s, it was determined that bacterial chemotaxis resulted from the regulation of flagellar rotation by chemoreceptors.
