Abstract
Polymorphonuclear neutrophils (PMN) are the most abundant circulating immune cells and represent the first line of immune defense against infection. This review of the biomedical literature of the last 40 years shows that they also have a powerful antitumoral effect under certain circumstances. Typically, the microenvironment surrounding a solid tumor possesses many of the characteristics of chronic inflammation, a condition considered very favorable for tumor growth and spread. However, there are many circumstances that shift the chronic inflammatory state toward an acute inflammatory response around a tumor. This shift seems to convert PMN into very efficient anticancer effector cells. Clinical reports of unexpected antitumoral effects linked to the prolonged use of granulocyte colony-stimulating factor, which stimulates an intense and sustained neutrophilia, suggest that an easy way to fight solid tumors would be to encourage the development of intense peritumoral PMN infiltrates. Specifically designed clinical trials are urgently needed to evaluate the safety and efficacy of such drug-induced neutrophilia in patients with solid tumors. This antitumoral role of neutrophils may provide new avenues for the clinical treatment of cancer.

Abstract
BACKGROUND There is growing evidence for a pathogenic role for cytokines in atherogenesis. The presence of certain cytokines has been documented in human atherosclerotic vessels. This study was designed to investigate cytokine production by mononuclear leukocytes from patients with ischemic heart disease. METHODS AND RESULTS We measured kinetics of secretion of tumor necrosis factor-alpha (TNF-alpha) and interferon-gamma (IFN-gamma) by mononuclear leukocytes from 8 control subjects, 10 patients with stable angina pectoris, and 10 patients with unstable angina pectoris. Mononuclear leukocytes were isolated and incubated with or without the plant lectin mitogen concanavalin A for 48 hours. TNF-alpha and IFN-gamma secretion were measured by ELISA. The effect of TNF-alpha and IFN-gamma on superoxide radical generation by neutrophils was also examined. Secretion of both TNF-alpha and IFN-gamma by mononuclear leukocytes increased progressively over 48 hours, and it was consistently higher (P < .02) in patients compared with control subjects. A similar increase in cytokine secretion was observed in patients with stable or unstable angina pectoris. In addition, there was no relation between the severity of coronary artery disease by angiography and cytokine secretion. Basal neutrophil superoxide radical generation was increased in patients with ischemic heart disease, and incubation with cytokines failed to further stimulate superoxide generation in these patients. CONCLUSIONS Similar increases in cytokine secretion by mononuclear leukocytes in stable or unstable angina pectoris indicate that the increased cytokine release is not a nonspecific inflammatory response in acute myocardial ischemia. Increased cytokine secretion in ischemic heart disease may play a role in superoxide radical generation, endothelial injury, deposition and activation of cellular elements on the vessel wall, and possibly in the progression of atherosclerosis.

Abstract
Mezerein, the most active antitumor compound isolated from the daphne species of plants, has a structural similarity to phorbol myristate acetate (PMA), the major active compound isolated from croton oil. PMA is known to have tumor promoting activity and is a potent inflammatory agent. Mezerein has similarly been reported to have potent inflammatory properties but appears to be a weaker tumor promoter than PMA. While the effect of PMA on the function and metabolism of human blood cells has been extensively studied, there is little similar information concerning mezerein. Therefore, in these studies, we have compared the capacities of mezerein and PMA to activate the cytotoxic capacity and oxidative metabolism of human granulocyte (PMNs), monocyte, lymphocyte, and mononuclear cell (lymphocytes and monocytes) cultures in vitro. Mezerein stimulated the oxidative metabolism of PMNs in an identical manner to PMA as indicated by a burst in the activity of the HMPS pathway, the production of H2O2, hydroxyl radical and stable oxidants. Mezerein also stimulated the release of thromboxane B2 from PMNs. Both compounds activated the oxidative metabolism of monocytes but not the oxidative metabolism of lymphocytes. The enhanced oxidative metabolism of the phagocytic cells was associated with an increased cytotoxicity against human red cells which are sensitive to oxidant damage but not against the NK resistant Raji lymphoblast cell line or the SW1116 colon tumor cell line. Of interest is that mezerein did not augment significantly the minimal cytotoxic capacity (NK activity) of mononuclear cells, monocytes or freshly isolated lymphocyte cultures against the tumor cell targets used in our experiments. However, lymphocyte cultures preincubated for 15 hours with mezerein had a marked enhancement of cytotoxicity against the tumor targets. This activation was not observed in similarly treated mononuclear cell cultures suggesting a suppressor activity of the monocytes. Our data suggest that the potent inflammatory activity of mezerein similar to PMA, may be related to its capacity to activate the oxidative and arachidonic metabolism of phagocytic cells. In addition, the capacity of mezerein to activate the cytotoxic capacity of lymphocytes may relate to its reported in vivo antitumor activity.

Abstract
The in vitro effects of methotrexate, vincristine, dexamethasone and adriamycin to modulate the antibody dependent cellular cytotoxicity (ADCC) reaction and secretion of superoxide (O2-) and hydrogen peroxide (H2O2) by phorbol myristate acetate (PMA) stimulated rat peritoneal macrophages were studied. Macrophage-mediated ADCC, as measured by the lysis of 51Cr-labeled IgG-coated sheep red blood cells in an 18 h assay, was significantly enhanced in the presence of 100 ng/ml of PMA. Treatment of macrophage monolayers for 24 h with vincristine (10(-5)-10(-7) M), dexamethasone (10(-5)-10(-9) M) and adriamycin (10(-6) M) inhibited ADCC by PMA stimulated macrophages. Vincristine, dexamethasone and adriamycin also inhibited the secretion of O2- and H2O2 by PMA stimulated macrophages at similar concentrations that reduced the ADCC reaction. Methotrexate (10(-3)-10(-7) M) did not inhibit either ADCC or O2- and H2O2 secretion by PMA stimulated macrophages. These results suggest that select anticancer drugs can inhibit macrophage mediated cytotoxicity of antibody coated target cells by suppressing the release of reactive oxygen intermediates by activated macrophages.

Abstract
Antitumor activity of phorbol myristate acetate-(PMA) stimulated neutrophils was measured against CCRF-CEM cells. Neutrophils and tumor cells were incubated (a) as a suspension with continuous mixing to maximize the availability of oxygen or (b) after centrifugation as a pellet to maximize cell-cell contact. The cells were then incubated briefly as a suspension with [14C]glutamine under conditions that blocked further damage to the tumor cells. When cells were incubated as a suspension, inhibition of tumor-cell glutamine uptake was mediated by the myeloperoxidase/hydrogen peroxide/chloride system of stimulated neutrophils. Inhibition was blocked by adding catalase, an inhibitor of myeloperoxidase, or compounds that scavenge hypochlorous acid or chloramines. When cells were incubated as a pellet, a portion of the inhibition could not be blocked in this way, indicating that a nonoxidative mechanism contributed to inhibition. In both systems, inhibition of glutamine uptake was rapid and was obtained at effector-cell/target-cell ratios as low as 0.5:1. This inhibition was obtained under conditions that did not result in 51Cr release from cells labeled with [51Cr]-chromate, indicating that inhibition of glutamine uptake measured cytotoxicity rather than cytolysis. 51Cr release was observed only when cells were incubated together for an hour or more as a pellet at high E/T ratios. This cytolysis was mediated by the myeloperoxidase system, and a nonoxidative contribution to cytolysis was not observed. The results indicate that stimulated neutrophils are potent antitumor effectors cells when cytotoxicity rather than cytolysis is the measure of activity. Because glutamine is required for growth of many tumor cells, inhibition of glutamine uptake may represent a significant tumoristatic or tumoricidal effect.

Abstract
We have characterized a model system for the study of antibody-dependent cytotoxicity (ADCC) mediated by human macrophages and monocytes. The U937 cell line is used as a source of effector cells. We confirmed a previous report (Gidlund et al., 1981) that U937 can be activated using PMA to kill in ADCC, and the characteristics of the observed cytotoxicity are described. Activation of effectors was maximal after 20-hr preincubation in the presence of 10 ng/ml PMA. In these conditions, lysis was approximately 70% in 2 hr at an effector to target ratio of 5:1. Activation correlated with the expression of complement receptors CR1 and CR3. No antibody-independent cytotoxicity was observed. The effects of various inhibitors of oxygen species were investigated: the lysis obtained in the above conditions was inhibited at 50% in the presence of either 450 mM dimethyl sulphoxide or 30,000 U/ml catalase, but superoxide dismutase (up to 10,000 U/ml) or ferricytochrome c (up to 2 mM) had no effect. The same inhibition was observed with 40 mM desferrioxamine or with 1 mM 0-phenanthroline, which are both iron scavengers, or in the presence of 300 microM colchicine or 1.5 microM dihydrocytochalasin B, which are two inhibitors of cytoskeletal functions. An identical effect was obtained in the presence of 1 TIU/ml bovine pancreas trypsin inhibitor, whereas soya bean trypsin inhibitor, which is more specific, had no effect up to 5000 BAEE U/ml. No inhibition was seen with protein synthesis inhibitors as cycloheximide or puromycin at 40 micrograms/ml. The significance of these results is discussed.

Abstract
Ten monoclonal antibodies (moAb) directed against cell surface antigens of guinea-pig monocytes and macrophages (mph) were produced and characterized. The corresponding antigens are not present on granulocytes, T lymphocytes, an Ia-positive B-cell line or other haematopoietic cells. In binding or cytotoxicity assays, the moAb demonstrated characteristics patterns of reactivity, with mph being in different stages of differentiation or activation. Three moAb (342, 322, 249) recognized 'lineage antigens' (i.e. antigens continuously expressed during maturation of monocytes to mph and after stimulation or activation of the cells). MoAb 342 possibly defines a major cell surface determinant, being present on 90% of mph. The antigens detected by moAb 305, 320, 321 and 344 characterize mature mph. They were not expressed on monocytes, but were expressed on the majority of resident, elicited or activated peritoneal mph. MoAb 253, 310 or 257 defined discrete subpopulations of elicited and--with the exception of moAb 257--activated mph. The corresponding antigens were not present on monocytes or resident mph, but appeared on the cell surface during in vivo or in vitro stimulation of the cells. There was no indication of a contribution of the moAb-defined antigens to the presentation of antigen, mitogen or alloantigen by the mph to T cells. The functional significance of the antigens thus remains to be elucidated. Our studies indicate that cells committed to the monocyte/mph lineage share a family of differentiation antigens, distinguishing them from other cell lines. The moAb provide useful tools for further investigation of the activation of mph and allow the rapid detection of mph in different tissues.

Abstract
Recent evidence indicates that phagocytic cells play a major role in tissue inflammation. The release of enzymes, lipid metabolites such as prostaglandins, and reactive oxygen species by these cells appear to mediate the inflammatory process. In this study we have evaluated the effects of diethyldithiocarbamate (DDC) on human monocyte function and metabolism. We demonstrate that DDC impairs that antibody-dependent cytoxicity (ADCC) of monocytes to red cell targets. The concentration of DDC which caused maximal suppression of ADCC also prevented the burst of oxidative metabolism in monocytes stimulated by sensitized red cells targets or phorbol myristate acetate (PMA). DDC also impairs the lipid metabolism of these cells as indicated by a decrement in malonyldialdehyde (MDA) production. These data indicate that DDC impairs the activity of two major biochemical pathways in monocytes which are related to the inflammatory process, i.e., the release of oxygen metabolites and prostaglandins.

Abstract
The effect of phorbol myristate acetate (PMA) on the antibody-dependent cellular cytotoxicity (ADCC) of human polymorphonuclear leukocytes (PMNs) against human erythroleukemic K562 cells was studied by the use of a 3-h 51Cr-release assay. Pretreatment of PMNs with PMA (10 ng/ml) for 60 min resulted in inhibition of subsequent ADCC. This inhibition was dependent on doses of PMA. The effect of pretreatment of PMNs with PMA on O2- generation of the cells was also studied. The ability of the cells to generate O2- was not suppressed, and the expression of Fc receptors on the cell membrane was well preserved. In contrast, the addition of PMA to the ongoing ADCC (5 to 30 min after the start of the ADCC assay) enhanced the activity of the cells for ADCC. This augmentation was abolished by catalase, whereas ADCC itself was not affected by the agent. These results imply divalent effects of PMA on the ADCC of PMNs. The suppression of ADCC activity of PMNs by pretreatment with PMA is not due to inhibition of the reactive oxygen burst of the cells. The augmentation of ongoing ADCC by the addition of PMA is due to secretion of hydrogen peroxide from the cells induced by PMA, and this augmentation occurs only when the interaction between effector and target cells exists through Fc receptor.

Abstract
Polymorphonuclear leukocytes (PMN) were studied for their ability to mediate cytotoxicity against varicella-zoster virus (VZV)-infected and uninfected human fibroblasts in 51Cr release assays. PMN were capable of mediating antibody-dependent cellular cytotoxicity (ADCC) against VZV-infected targets. Maximal ADCC was obtained with effector-to-target ratios of 100:1 and 18 h of incubation. Percent 51Cr release for 26 normal adults was 14.1 +/- 0.6 (mean +/- standard error) in the presence of pooled human seropositive sera (final dilution, 1:100) and 0.5 +/- 0.6 in the presence of pooled human seronegative sera. Addition of phorbol myristate acetate (PMA) enhanced PMN-mediated cytotoxicity against VZV-infected and uninfected targets. PMA-stimulated cytotoxicity was optimal with PMA concentrations of 200 ng/ml and effector-to-target ratios of 10:1, and antibody was not required; killing was detected as early as 3 h after incubation and was maximal after 18 h. Highly purified PMN were capable of mediating both ADCC and PMA-stimulated lysis. Catalase completely inhibited PMA-stimulated PMN cytotoxicity, but had no effect on PMN-mediated ADCC. PMN from patients with chronic granulomatous disease were capable of mediating ADCC, but not PMA-stimulated killing, against VZV-infected targets. Thus, PMN could kill VZV-infected targets by two different mechanisms: ADCC, which required antibody but not hydrogen peroxide (H2O2), and PMA-stimulated cytotoxicity, which required H2O2 but not antibody.
