An eosinophil chemotactic factor (ECF) can be released from human polymorphonuclear neutrophils by arachidonic acid (AA), its methyl ester, but not by other derivatives such as AA ethyl ester and arachidonyl acetate. The ECF is highly specific for eosinophils and does not attract polymorphonuclear neutrophils. A dose-dependent non-cytotoxic ECF release

Chemotactic factors for bovine leukocytes
American Journal of Veterinary Research, 1982SUMMARY An agarose method was used to determine the nature of chemotaxins for bovine leukocytes as related to coliform mastitis. Freshly collected bovine serum or plasma was frequently chemotactic, probably due to spontaneous complement activation. Fresh serum was always rendered chemotactic when activated with zymosan or when heat-killed or viable ...

Chemotactic factors and renal inflammation
American Journal of Kidney Diseases, 1998The mechanisms of leukocyte entry into the kidney during inflammatory renal disease have recently received considerable attention. Chemotactic factors appear to play a central role in this process, not only by inducing leukocyte movement but also by enhancing endothelial and leukocyte adhesiveness and endothelial permeability.

Are Growth Factors Chemotactic Agents?
Experimental Cell Research, 1995We report the first direct observation of chemotaxis in slowly moving malignant cells. Two sarcoma cell lines of different metastatic potential were used. In a direct-viewing chemotaxis chamber with two concentric wells, the pooled trajectories of highly malignant rat T15 cells were strongly biased toward the outer well which contained platelet-derived

Eosinophil Chemotactic Factor (ECF)
International Archives of Allergy and Immunology, 1976Eosinophil chemotactic factor (ECF) can be released from human peripheral leukocytes by an IgE-anti-IgE reaction, by the calcium ionophore A 23187 and during phagocytosis. Supernatants and sonicates of unstimulated cells contain little or no ECF. On stimulation, however, ECF activity increases in the cells and even more so in the supernatants.

Neutrophil chemotactic factors
1991Polymorphonuclear leukocytes (neutrophils) are recruited to inflammatory sites by a variety of soluble mediators (chemoattractants) that stimulate neutrophil directed migration (chemotaxis). Many neutrophil chemoattractants such as neutrophil activating proteins, leukotriene B4 (LTB4), platelet activating factor, and complement-derived C5a, are ...

Neutrophil Chemotactic Factors in Bacterial Pneumonia
Chest, 1989The influx of neutrophils into the lung is a prominent feature in patients with bacterial pneumonia. Since neutrophils migrate in response to chemotactic factors, chemotactic activity was evaluated in bronchoalveolar lavage (BAL) fluid obtained from 12 patients with bacterial pneumonia and ten normal control subjects.

Chemotactic factor(s) ofNeisseria gonorrhoeae
Current Microbiology, 1978When grown in defined media, 15 of 21 laboratory and clinical strains ofNeisseria gonorrhoeae produced one or more factors (cytotaxins) chemotactic for human polymorphonuclear leukocytes obtained from normal individuals. Production of the cytotaxin(s) depended upon the media in which the bacteria were grown and the growth phase of the cultures, as well
