Neutrophils are the primary cells recruited to inflamed sites during an innate immune response to tissue damage and/or infection. They are finely sensitive to inciting stimuli to reach in great numbers and within minutes areas of inflammation and tissue insult.

SIAM Journal on Mathematical Analysis, 2000
There is considered a coupled system of elliptic equations together with boundary conditions which model steady state solutions of a reaction-difussion system describing the competition in a nonmixed bioreactor with chemostatic response. The autor is interested in the existence of its positive solutions.

Annual Review of Physiology, 1982
Dictyostelium discoideum exists as single amoeboid cells during the first phase of its developmental cycle. These cells phagocytose bacteria. Chemo taxis to compounds released from the bacteria (e.g. folic acid) is probably involved in food seeking (95).

LYMPHOCYTES are motile cells whose movement in vivo seems to be directed, yet investigators over many years have repeatedly failed to show chemotaxis of lymphocytes in vitro. There have been some recent reports that lymphocytes migrate into micropore filters towards substances placed below the filter1–3, but this migration was not found to be ...

Annual Review of Biophysics and Bioengineering, 1975
Bacteria swim by rotating their flagella. They alter course by abruptly changing the direction of this rotation. The probability of the occurrence of this event is biased by chemoreception. The bias depends on the way in which the concentration of the attractant or repellent changes with time. Sugars are detected as they bind to specific proteins which

Diabetes and neutrophil chemotaxis
Diabetes, 1977The chemotaxis of PMN cells from adult and juvenile diabetics and proper control subjects was found to be comparable. Similarly, chemotactic activity generated from diabetic sera was not different from the activity generated from the normal sera.

The chemotactic properties of spores of Actinoplanes brasiliensis were examined. The spores are attracted to chloride and bromide solutions but not to a number of organic compounds that are capable of supporting growth in chemically defined media. Chloride attraction has been tested in several other species of the genus and in a number of Actinoplanes ...

Reviews of Reproduction, 1999
Communication between spermatozoa and egg before contact by chemotaxis appears to be prevalent throughout the animal kingdom. In non-mammalian species, sperm chemotaxis to factors secreted from the egg is well documented. In mammals, sperm chemotaxis to follicular factors in vitro has been established in humans and mice.

Phosphoinositides in Chemotaxis
2012Phosphatidylinositol lipids generated through the action of phosphinositide 3-kinase (PI3K) are key mediators of a wide array of biological responses. In particular, their role in the regulation of cell migration has been extensively studied and extends to amoeboid as well as mesenchymal migration.

Chemotaxis assays have a number of applications in the study of leukocyte biology and immune/inflammatory pathology. Multiwell "blind chamber"-type assays allow a large number of parallel measurements within a single assay. The development of fluorescence assays using microplate-based chemotaxis chambers has permitted a degree of automation to be ...
