Neutrophil Granulocytes

Basic (pH) proteins directed against pathogens. Examples are the major basic protein from mast cells, the eosinophilic cationic proteins from eosinophils, and defensins from epithelial cells and neutrophilic granulocytes. 

Cell migration and cytoplasmic movement involve predominantly actin filaments in the locomotion of neutrophilic granulocytes, both actin filaments and microtubules in the elongation of neuronal growth cones and migration of neurites, and both actin and myosin in cytokinesis and the contraction of skeletal and cardiac muscle.

Both clinical and sub-clinical mastitis are usually accompanied by an increase in the somatic cell count (SCC a measure of white blood cells (95%) such as macrophages, segmented neutrophil granulocytes or lymphocytes) in milk. SCCs above a certain level are an indication of immune-system activation and are used as an indicator of sub-clinical , latent or chronic udder infections/mastitis (Concha, 1986 Ostensson et al., 1988), which were shown to affect milk quality, composition and shelf life. Dairy companies therefore impose SCC thresholds or reduce payments to farmers if certain thresholds are exceeded (Hamann, 2001 Urech et al., 1999).

The presence of a certain number of amino acids is significant for the restitution of the immune system s cells, interferon synthesis process and other factors realization of the immune defense system. The decrease of full-form protein consumption is one of the causes of secondary immune-deficiency states. The significance of ascorbic acid presence for the immune system is supported by the fact that its concentration in the neutrophil granulocytes is 150 times higher than in the blood serum. The significance of retinol s and carotenoids role is supported in the cases of cell differentiation, where DNA synthesis increase, and proliferation decrease thus stabilizing the organism when under infection. 

Leukotrienes increase capillary permeability and serve as chemotactic factors for neutrophil granulocytes. As "slow-reacting substances of anaphylaxis," they are involved in allergic reactions (p. 326) together with PG, they evoke the spectrum of characteristic inflammatory symptoms redness, heat, swelling, and pain.

Takemura et al. [155] described TUNEL positivity, and Hayakawa et al. [152] described caspase-3 positivity in infiltrated and proliferated interstitial cells in an experimental model of MI, suggesting that apoptosis might play an important role in the disappearance of these cells after MI. Consistent with these studies, we found positive reaction for cleaved caspase-3 in neutrophil granulocytes in the interstitium in acute MI in humans (Fig. 4B).

The most notable feature of the dynamic response of the process to large perturbations in the number of blood cells is that the system rings, displaying an oscillatory behavior in the number of cells in the blood and other compartments of the system, as a function of time. Such large perturbations are produced by leukopheresis or exposure of the system to disease, which depletes the number of blood cells, and in total body irradiation experiments or some drug treatments as chemotherapy, which deplete the total number of cells in the production process of neutrophil granulocytes.
