Inflammation is present in the lungs of all smokers. It is unclear why only 15% to 20% of smokers develop COPD, but susceptible individuals appear to have an exaggerated inflammatory response.5 O The inflammation of COPD differs from that seen in asthma, so the use of anti-inflammatory medications and the response to those medications are different. The inflammation of asthma is mainly mediated through eosinophils and mast cells. In COPD the primary inflammatory cells include neutrophils, macrophages, and CD8+ T lymphocytes.

Release of cytokines injures acinar cells and enhances the inflammatory response. Injured acinar cells liberate chemoattractants that attract neutrophils, macrophages, and other cells to the area of inflammation, and increased vascular permeability promotes tissue edema. 

The most common etiology is exposure to environmental tobacco smoke, but other chronic inhalational exposures can also lead to COPD. Inhalation of noxious particles and gases stimulates the activation of neutrophils, macrophages, and CD8+ lymphocytes, which release a variety of chemical mediators, including tumor necrosis factor-a, interleukin-8, and leukotriene B4. These inflammatory cells and mediators lead to widespread destructive changes in the airways, pulmonary vasculature, and lung parenchyma.

The two major components of the immune system are soluble factors and cells. The former include complement, cytokines and antibodies. The cells include lymphocytes, neutrophils macrophages and eosinophils (see Appendices 17.1 and 17.2). The most numerous are the lymphocytes. 

Pharmacology Nedocromil is an inhaled anti-inflammatory agent for the preventive management of asthma. It inhibits the in vitro activation of, and mediator release from, a variety of inflammatory cell types associated with asthma, including eosinophils, neutrophils, macrophages, mast cells, monocytes and platelets. Nedocromil inhibits the development of early and late bronchoconstriction responses to inhaled antigen.

Peroxidases. Another group of enzymes, which is involved in the oxidation of xenobiotics, is the peroxidase. There are a number of these enzymes in mammalian tissues prostaglandin synthase found in many tissues, but especially seminal vesicles and also the kidney, the lung, the intestine spleen, and blood vessels lactoperoxidase found in mammary glands myeloperoxidase found in neutrophils, macrophages, liver Kupffer cells, and bone marrow cells. 

The A3AR is expressed in relatively high densities in lung, liver, neutrophils, macrophages, and glial cells. In the heart and brain, there are distinct effects on cell survival, but the A3AR is expressed at a much lower level. Its presence on neurons in the central nervous system was controversial, but now well established (Lopes et al. 2003 Yaar et al. 2002).

Twenty years ago, a high-affinity-binding site for uPA was demonstrated on the surface of peripheral blood monocytes and cultured cells of the human histiocytic lymphoma cell line, U937 [46]. The expression of uPAR on the cell surface of many cell types has since then been demonstrated, including a variety of neoplastic cell lines as well as nonneoplastic cells such as neutrophils, macrophages, keratinocytes, placental trophoblasts, endothelial, and smooth muscle cells [7, 33, 47-51]. The human uPAR gene has been mapped to chromosome 19ql.3 [52]. 

Differential cell counts of the BAL and peritoneal fluids are performed on cytospin-prepared slides. Differential counts of leukocytes in peripheral blood are performed on blood smears. The slides are stained with Diff-Quik (American Scientific Products, McGaw Park, IL) and at least 200 cells are counted per sample to determine the percent of neutrophils, macrophages, lymphocytes, and other cells. 

Distribution Erythromycin distributes well to all body fluids except the cerebrospinal fluid (CSF). It is one of the few antibiotics that diffuses into prostatic fluid and has the unique characteristic of accumulating in macrophages. It concentrates in the liver. Inflammation allows for greater tissue penetration. Similarly, clarithromycin and azithromycin are widely distributed in tissues. Serum levels of azithromycin are low the drug is concentrated in neutrophils, macrophages, and fibroblasts. 

It is well-established that a major response to septic stimuh in general is the activation (primarily by cytokines and bacterial products, conditions that as described above also can induce NO synthesis) of phagocytic cells (neutrophils, macrophages) to produce ROS, through the respiratory burst mechanism this is a major immune mechanism for combating infectious agents but also can be damaging to the host. 

The pathophysiology of VKC is derived from a combination of type I and IV hypersensitivity reactions.This allergic response involves IgE,Th-2 lymphocytes, eosinophils, mast cells, basophils, neutrophils, macrophages, proin-flammatory cytokines, interleukins, histamine, and other associated mediators. Also involved in this immune response are hormonal and neuroendocrine influences. This immune response results in the clinical manifestations of photophobia, itching, redness, tearing, papillae, corneal vascularization, mucous discharge, and plaque formation. 

The circulatory system contains a number of types of cells. Nearly half of the volume of whole blood consists of red blood cells whereas only about / of the blood consists of white blood cells. The function of the red blood cells is to transport ojtygeri to the tissues. White blood cells are part of the immune system. There are several types of white blood ceils neutrophils, macrophages, and lymphocytes. Neutrophils are also called polymorphonuclear leukocytes. The smallest type of ceil in the bloodstream is the platelet. Platelets are used in the clotting of blood, as outlined under Vitamin K. 

Cathelicidins and defensins induce histamine release from mast cells [182-184]. Human BD-2, -3 and -4 and a-defensins recruit monocytes, T cells (memory and naive) and immature dendritic cells [185-188] Cathelicidins (bovine, human, mouse and pig) are chemotactic for several subsets of peripheral blood cells in vitro [178,189] and in vivo [190]. For example, CRAMP (Cathelin-related antimicrobial peptide, the murine orthologue of human cathelicidin/LL-37), like LL-37, was chemotactic for human monocytes, neutrophils, macrophages, and for mouse peripheral blood leukocytes in vitro and in vivo [189]. These results suggest that host defense peptides recruit innate and adaptive immune cells for protective cellular and humoral responses to pathogens. 

Under normal conditions, the alveolar epithelial and endothelial cell layers that make up the air-blood barrier control the passage of fluids and cells between the air spaces of the lung and the interstitium. Damage to this delicate barrier can cause an inflammatory response and the impairment of lung function. Changes in the permeability of the alveolarcapillary barrier lead to an infusion of proteinaceous serous fluid (edema) and blood cells (neutrophils, macrophages, and eosinophils). This influx of cells usually peaks within the first 3-7 days of the inflammatory response. If the inflammation is sustained it is... 

The cellular locations of leukotriene biosynthesis are determined by the distribution and location of the enzymes needed for their production. 5-Lipoxygenase is found in only a limited number of specific cell types, predominantly of myeloid extraction. Because of this restricted expression, production of LTA4 is largely limited to those cells (e.g., basophils, eosinophils, neutrophils, macrophages, mast cells, and monocytes) (66). These cells produce LTA4, further process it to either LTB4 or LTC4, or secrete it.
