Abstract
Cancer is a multi-faceted disease in which spontaneous mutation(s) in a cell leads to the growth and development of a malignant new organ that if left undisturbed will grow in size and lead to eventual death of the organism. During this process, multiple cell types are continuously releasing signaling molecules into the microenvironment, which results in a tangled web of communication that both attracts new cell types into and reshapes the tumor microenvironment as a whole. One prominent class of molecules, chemokines, bind to specific receptors and trigger directional, chemotactic movement in the receiving cell. Chemokines and their receptors have been demonstrated to be expressed by almost all cell types in the tumor microenvironment, including epithelial, immune, mesenchymal, endothelial, and other stromal cells. This results in chemokines playing multifaceted roles in facilitating context-dependent intercellular communications. Recent research has started to shed light on these ligands and receptors in a cancer-specific context, including cell-type specificity and drug targetability. In this review, we summarize the latest research with regards to chemokines in facilitating communication between different cell types in the tumor microenvironment.

Abstract
It has been reported that high levels of cholesterol and triglycerides are associated with increased risk of developing atherosclerosis and shorter life. In fact, vascular endothelial dysfunction occurs during the human aging process. Accumulation of lipids in vascular endothelium activates leukocytes to produce cytokines and chemokines which recruit macrophages. On the other hand, macrophages augment inflammatory response and secrete vascular endothelial growth factor, a key cytokine that mediates angiogenesis and inflammatory response. In addition, hyperlipidaemia is one of the main risk factors for aging, hypertension and diabetes. Here, we review the interrelationship between endothelial cells, high level of cholesterol, and aging.

Abstract
The anti-tumour antibiotic Bleomycin, the experimental immunostimulatory tripeptide FK 565, and the immunosuppressive agent Cyclosporin A were examined for their in vitro effects on the release of the haemopoietic cytokine Granulocyte Macrophage Colony-Stimulating Factor (GM-CSF) from LPS stimulated BALB/c adherent peritoneal macrophages. FK 565 and Bleomycin produced an increase in GM-CSF release indicating that these agents are capable of stimulating peritoneal macrophage populations. Cyclosporin A was found to have no effect.

Abstract
Interleukin-8 (IL-8) is a chemoattractant cytokine for polymorphonuclear neutrophils, and is found at the site of inflammation and infection. The levels of IL-8 from an elderly (ages 65-79) and young (ages 20-27) population were compared. Secretion of IL-8 was measured in monocyte conditioned medium (MCM), under both a spontaneous condition and with stimulation with detoxified LPS (10 mg/ml). Spontaneous production of IL-8 in the elderly group (39.4 +/- 8.3 ng/ml, n = 16) was found to be significantly lower than the control group (66.4 +/- 5.0 ng/ml, n = 17), P < 0.01. A sex difference was observed within the elderly population, with the male elderly producing 8.8 +/- 2.1 ng/ml of IL-8 and the elderly females producing levels of 57.8 +/- 9.1 ng/ml. There was a good correlation between IL-8 and IL-1 production in the elderly but differences between the elderly and young production of IL-1 did not reach statistical significance. IL-8 and TNF production did not correlate. Upon stimulation with the LPS, the male elderly levels increased eightfold (70.1 +/- 11.8 ng/ml) and was significantly different from the young male level, P < 0.01, while the female elderly showed no change with stimulation. No sex difference was observed in the control population. These results indicate that the spontaneous secretion of IL-8 in elderly males is lower than that of both elderly females and the young control group. However, upon stimulation with LPS, the elderly males are capable of an overproduction of IL-8 when compared to the young group and the elderly females. This overproduction may be the result of an in vivo priming in this healthy elderly group. The female elderly followed a pattern similar to the young group, showing no change upon stimulation with the detoxified LPS. Sex differences related to the immune system have been noted in the past with females having a more active immune system, and these results may be related to this difference.

Abstract
Bacterial infections in the immunocompromized host cause considerable mortality, and even the recently developed antimicrobial strategies often fail to cure these infections, especially in granulocytopenic patients. Cytokines and hematopoietic growth factors have been shown to stimulate host defense mechanisms in vitro and in vivo. We discuss the possible role of the pro-inflammatory cytokines interleukin-1, tumor necrosis factor-alpha, interleukin-6 and interleukin-8 as modulators of host resistance to bacterial infections. Interleukin-1 has been shown effective in various animal models of potentially lethal bacterial infection, even during severe granulocytopenia. The protective mechanism of interleukin-1 may be mediated via downregulation of cytokine receptors and cytokine production, and via induction of acute phase proteins. Moreover, in subacute and chronic infections interleukin-1 interferes with microbial outgrowth, via mechanisms that have only been partially elucidated.

Abstract
The incidence of invasive fungal infections in the immunocompromized host has increased during the past decade. Even the recently developed antifungal drugs are unable to cure these infections in patients with severely impaired host defense mechanisms. Cytokines have great potential to augment host resistance and as adjunctive therapy of invasive mycoses. We discuss the mechanisms of host defense against invasive candidiasis, aspergillosis, and cryptococcosis, and review the use of cytokines and growth factors in this setting. Interleukin-1 has been shown effective in an animal model of disseminated candidiasis, even during severe granulocytopenia. Interferon-gamma has been very effective as a modulator of resistance against a variety of fungal infections in vitro. The effect of interferon-gamma against disseminated candidiasis has been demonstrated in a mouse model. Activation of neutrophils is the main mechanism by which interferon-gamma enhances the elimination of Candida, and consequently the agent is not effective in severely granulocytopenic animals. Data on the role of colony-stimulating factors against fungal pathogens are accumulating, and trials with these agents for hematologic patients with invasive fungal infections are now being performed.

Abstract
Ascites is a readily available source of human macrophages (M phi), which can be used to study M phi functions in vitro. We characterized the mediators of inflammation produced by human peritoneal M phi (hp-M phi) obtained from patients with portal hypertension and ascites. The production of the cytokines interleukin-1 beta (IL-1 beta), interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) was found to be lipopolysaccharide (LPS) concentration dependent (0-10 micrograms/ml) with a maximal production at 10 micrograms/ml and also dependent on the time of exposure to the stimulus (0-36 h). IL-1 beta, IL-6 and TNF-alpha production after LPS administration reached a plateau at 24 h. In vitro stimulation for 24 h with LPS does not influence the eicosanoid production from endogenous arachidonate. 13 min of exposure of the cells to the calcium ionophore A23187 gives a significant increase in eicosanoid production from both exogenous and endogenous arachidonate. The main eicosanoids produced are the 5-lipoxgenase products LTB4 and 5-hydroxyeicosatetraenoic acid (HETE). The increase in production of the other eicosanoids is not significant. The eicosanoid production depends on the stimulus concentration. The optimal A23187 concentration is 1 microM. Oxygen radical production was measured in the M phi by a flowcytometric method. The fluorescence intensity of phorbol 12-myristate 13-acetate stimulated and dihydro-rhodamine 123 loaded hp-M phi increases significantly after 15 min. We conclude that LPS stimulation of hp-M phi from liver disease results in similar production of IL-1 beta, IL-6 and TNF-alpha, but that the profile of the eicosanoid production of these M phi stimulated with LPS and A23187 differs from M phi of other origin and species.

Abstract
Gamma interferon activation factor (GAF) rapidly induces transcriptional activation of gamma interferon (IFN-gamma)-responsive genes. Conversion of the GAF from a latent cytoplasmic to an activated, DNA-binding form is an immediate step in the cellular response to IFN-gamma. The amount of IFN-gamma-activated GAF, measured by exonuclease III protection or gel shift assays, increased strongly upon monocytic differentiation of U937 cells. Activated GAF contained the IFN-responsive 91-kDa protein as its DNA-binding activity in gel shift or exonuclease III assays could be inhibited through direct addition of specific antiserum, and it was not present in p91-immunodepleted extracts. There was a differentiation-induced increase in the amount of nonphosphorylated (latent) p91. Transcription rate measurement demonstrated a strong induction of the p91 gene during monocytic differentiation of U937 cells. The amount of p91 which was rapidly phosphorylated in response to IFN-gamma was found to be much higher in the differentiated cells and suggested a differentiation-controlled increase in the signaling leading to p91 phosphorylation. Concomitantly with a better GAF response, transcriptional activation of IFN-gamma-induced genes and the expression of GAF-dependent, transfected reporter plasmids increased in differentiated U937 monocytes. The promonocyte-monocyte transition also affected the IFN-alpha-responsive transcription factor ISGF-3. Differentiated U937 cells contained more of both the alpha-component p91 and the gamma-component p48, which constitutes the DNA-binding subunit of the complex. Our study thus provides evidence that the synthesis of specific transcription factors can be a regulated event to control the cytokine responsiveness of cells during development.

Abstract
The results obtained with RP 54745, an amino-dithiole-one compound, on stimulated macrophages, revealing inhibition of the hexose monophosphate pathway (HMP), of the exocytosis of lysosomal enzymes and of the production of interleukin-1 (IL-1), by the compound in vitro as well as in vivo, suggested that RP 5475 might influence cells and cytokines implicated in the regulation of the immune system, the disfunctioning of which can lead to inflammatory disorders or autoimmune pathologies. RP 54745 was effective at moderate oral doses (around 5 mg kg-1) in different mouse models of induced arthritis and in the MRL/lpr mice, genetically predisposed to develop an autoimmune pathology including arthritic disorders. The clinical status of the MRL mice, and several of their disturbed biochemical and immunological parameters, improved after a 3-month treatment with RP 54745. This activity of RP 54745 makes it a very attractive antirheumatic compound and a potentially effective treatment in pathologies where IL-1 production is exacerbated.

Abstract
Distinct subpopulations of macrophages or differently activated macrophages display various functions in immune reactions. Some of their activities depend on specific sets of factors (i.e., cytokines and eicosanoids) produced by activated macrophages. We have studied the ability of murine (CBA/ca) peritoneal macrophages to selectively release tumor necrosis factor alpha (TNF-alpha), interleukin 1 (IL-1), and IL-6. We have found that the priming of cells (Mo) with different stimulants (thioglycolate vs. LPS) induces the release of particular cytokines by reactivated macrophages. The increased release of TNF-alpha correlates with lower levels of IL-1 and IL-6. We have also found that prostaglandin E2 (PGE2) and prostacyclin (PGI2) have opposing effects on the production of two of these cytokines. The release of TNF-alpha is inhibited by prostaglandins, whereas increased levels of PGE2 and PGI2 correlate with higher levels of IL-6.

Abstract
A majority of angiogenic factors has been shown to be produced by macrophages. This review will give a concise description of their biochemical nature, their isolation from macrophages and their angiogenic activity. Among the factors with mitogenic effects on endothelial cells are basic fibroblast growth factor (bFGF), transforming growth factor-alpha (TGF-alpha) and very probably insulin-like growth factor-1 (IGF-1). Other secretory products such as angiotropin and human angiogenic factor (HAF) are nonmitogenic but promote angiogenesis by inducing migration of endothelial cells. Prostaglandins, platelet-derived growth factor (PDGF), granulocyte-macrophage- and granulocyte-colony stimulating factor (GM-CSF, G-CSF), interleukin 6 (IL-6) and angiotensin converting enzyme (ACE) have also been shown to be angiogenic, but their mode of action is still to be clearly defined. As the extracellular matrix appears to be involved in the control of angiogenesis, macrophage-derived factors that can alter this structure via degradation or via the clotting system will also be discussed. Tumor necrosis factor alpha (TNF-alpha), interleukin 1 (IL-1) and transforming growth factor-beta (TGF-beta) have complex actions on endothelial cells, and can partially inhibit angiogenesis. Among the factors which solely inhibit neovascularization are the interferons. As it is not known whether all of these factors play a role in angiogenesis in vivo attempts to detect them in situ during the course of neovascularization will be described. Finally macrophages will be discussed as cells that may not be mandatory for each phase of the angiogenic process but whose angiogenic capabilities are comprehensive and unsurpassed by any other cell.
