Given adequate chemotactic or other directional information, it is not impossible to imagine them making their way into the caeca by their own efforts.
Once within the tissue, the leukocyte follows a chemotactic gradient of chemokine signals towards the site of inflammation (fig002dab).
So, waves of chemotactic pulses can be propagated over a distance of much larger than the chemotactic action radius of an aggregation centre.
However, based on the nature of this study, the chemotactic response of nematodes to chemicals is of particular interest.
These two anaphylotoxins are chemotactic for neutrophils and can cause histamine release from mast cells and basophils.
To be pushed out, the bacteria inside the colony can emit repulsive chemotactic signals.
Platelets induce alterations of chemotactic and adhesive properties of endothelial cells mediated through an interleukin-1-dependent mechanism.
To self-engineer their colonial structure these bacteria regulate the balance between attractive and repulsive chemotactic signalling as well as their food chemotaxis.
The adhesion molecules and chemotactic agents shown are discussed in the text.
Release of prostaglandins (a type of eicosanoid) can lead to chemotactic attraction of inflammatory neutrophils.
Antibody-coated agar layers, containing antigen and the chemotactic factor, remained intact even after incubation for 120 min with human neutrophils and eosinophils, and thus provide a fully, non-phagocytosable model surface.
There one can find a short introduction to the different approaches modelling chemotactic movement of a mobile species and results on blowup of the solution of the classical chemotaxis model.
Since cervical ripening is associated with an influx of inflammatory cells into the cervix, it seems that cytokines with chemotactic properties may play a physiological role in this process.
Adhesion molecule complexes might be blocking the diffusion of parasite-derived eosinophil chemotactic factors into the surrounding tissues that would otherwise attract eosinophils.
