Abstract
HM1.24 antigen (CD317) was originally identified as a cell surface protein that is preferentially overexpressed on multiple myeloma cells. Immunotherapy using anti-HM1.24 antibody has been performed in patients with multiple myeloma as a phase I study. The aim of this study was to evaluate the anti-tumor activity of mouse-human chimeric and humanized anti-HM1.24 monoclonal antibodies (mAbs) against lung cancer cells in vitro. Human peripheral blood lymphocytes and monocytes separated from mononuclear cells (PBMCs) were used as effector cells. Antibody-dependent cellular cytotoxicity (ADCC) and complement-dependent cytotoxicity (CDC) of chimeric and humanized anti-HM1.24 mAbs against lung cancer cells were determined by chromium-release assay. In some experiments, target or effector cells were pretreated with various cytokines. Chimeric and humanized anti-HM1.24 mAbs effectively induced ADCC against lung cancer cells mediated more efficiently by lymphocytes than monocytes. The cytotoxic activity correlated with the level of HM1.24 expression on lung cancer cells. Natural killer cells were identified as the major effector cells in ADCC mediated by the anti-HM1.24 mAb. The treatment of lymphocytes or monocytes with IL-2, IL-12, IL-15, M-CSF, or IFN-gamma significantly increased the ADCC activity. Moreover, the culture of lung cancer cells with IFN-beta or IFN-gamma augmented their susceptibility to ADCC and CDC. PBMCs from patients with lung cancer induced a level of ADCC comparable to that induced by PBMCs from healthy donors. Chimeric or humanized anti-HM1.24 mAbs have potential as a new therapeutic tool in lung cancer, and in combination with interleukins and interferons, could be useful for enhancing ADCC.

Abstract
In this study, we investigated the generation of dendritic cells (DCs) from blood monocytes and mature macrophages from untreated primary lung cancer patients. Blood monocytes were separated by adherence from blood mononuclear cells (MNC) from ten lung cancer patients and ten control subjects, and cultured for 7 days in medium with granulocyte/macrophage colony-stimulating factor (GM-CSF) plus interleukin (IL-) 4. In all cases examined, DCs with typical characteristics were obtained even in lung cancer patients after 7 days culture with these cytokines, and there was no significant difference in phenotype and stimulatory activity in allogeneic lymphocyte proliferation between DCs derived from monocytes from lung cancer patients and those from control subjects. Next, we examined whether alveolar and pleural macrophages in malignant pleural effusion separated by magnetic beads could differentiate to immunostimulatory DCs. Conventional culture conditions with GM-CSF and IL-4 did not induce efficient numbers of DCs from mature macrophages, whereas the addition of tumor necrosis factor-alpha (TNF-alpha) to GM-CSF and IL-4 effectively contributed to generate DCs. These findings suggest that both mature macrophages and blood monocytes from lung cancer patients could differentiate to DCs, and might be a useful source of DCs for immunotherapy.

Abstract
The tumour-bearing state is known to induce immune dysfunction that contributes to increased infectious complications and tumour progression. However, the mechanisms underlying this immunosuppression remain unclear. This study investigated in a murine model the effects of melanoma growth on nitric oxide (NO) production by peritoneal macrophages in vivo and in vitro. B16 and K1735 melanoma cells were inoculated subcutaneously into C57BL/6 and C3H/HeN mice, respectively. Stimulated NO production by elicited peritoneal macrophages was examined in control and melanoma- bearing mice. An in vitro system was established to assess the effects of co-culturing melanoma cells (B16 and K1735) or melanoma-conditioned medium with normal peritoneal macrophages on subsequent NO production. NO production was significantly suppressed in macrophages from melanoma-bearing mice. Co-culture of normal macrophages with melanoma cells in a transwell system or with melanoma-conditioned media in vitro reproduced the defects observed in vivo without affecting macrophage viability, pointing to a melanoma-derived product as the basis for the observed suppression of NO production. This inhibition required RNA and protein synthesis and was dose and time dependent. Using inhibition profiles and neutralizing antibodies, it was demonstrated that this melanoma inhibitory activity was distinct from known NO inhibitors. Preliminary characterization attributed this activity to a melanoma-secreted protein moiety.

Abstract
Ganglioside GM2 is one of the major gangliosides expressed on the cell surface of human tumors including lung cancer. We have previously reported that a mouse-human chimeric monoclonal antibody (mAb), KM966, against GM2 promotes the lysis of lung cancer cells by human blood mononuclear cells (MNC) of healthy donors. In this study, we examined antibody-dependent cell-mediated cytotoxicity (ADCC) of MNC, using KM966 mAb and its humanized counterpart, KM8969, in 16 lung cancer patients and 18 control patients. The ADCC activity was assessed by 4-h (51)Cr release from GM2 positive SBC-3 small cell lung cancer cells. MNC from lung cancer patients exhibited similar ADCC activity to those from control patients when KM966 and KM8969 were used as mAb. Moreover, effective ADCC activity was observed even in MNC from advanced lung cancer patients. These observations suggest the potential activity of humanized anti-GM2 mAb (KM8969), as well as chimeric KM966, in biological therapy for lung cancer patients.

Abstract
The ability of blood lymphocytes of newly diagnosed lung cancer patients to respond to interleukin 2 (IL-2) to become IL-2-activated killer (LAK) cells and its regulation by autologous monocytes were examined. LAK activity was measured by 51Cr release assay. The abilities of lymphocytes among blood mononuclear cells (MNC) of subjects of different ages without malignancies to generate LAK activity against NK-cell resistant Daudi cells and lung adenocarcinoma (PC-9) cells were very similar. The LAK activity of blood MNC of lung cancer patients was also nearly the same as that of blood MNC of control subjects. There was no significant difference in IL-2-inducible LAK activity between MNC of patients with small cell lung cancer (SCLC) and those of patients with non-SCLC. Monocytes and lymphocytes were separated from blood MNC on a one-step Percoll gradient. Monocytes of lung cancer patients were found to augment in vitro induction of LAK activity by IL-2 of autologous blood lymphocytes. In contrast, endotoxin-stimulated monocytes suppressed LAK induction of autologous lymphocytes of cancer patients. These findings suggest that administration of IL-2 and LAK cells induced in vitro may be of benefit in the treatment of lung cancer.

Abstract
The effect of recombinant human interferon-gamma (rHuIFN-gamma) and interferon-alpha (rHuIFN-alpha) as in vivo stimuli for the activation of human monocytes was investigated on the basis of the bactericidal activity of peripheral blood monocytes in 11 patients with metastatic melanoma before and during treatment with interferons. Patients received increasing doses of rHuIFN-gamma and a fixed dose of rHuIFN-alpha, both administered subcutaneously three times a week. The rates of intracellular killing of Listeria monocytogenes and Salmonella typhimurium after in vitro phagocytosis by monocytes collected from melanoma patients before interferon treatment were increased (P less than 0.01) by a factor of 1.7 and 1.4, respectively, relative to the rate constants in blood monocytes of healthy donors. During treatment with the interferons, the rates of intracellular killing of the bacteria by patients' monocytes did not further increase. The findings underscore the immunogenicity of malignant melanoma and put into question the macrophage activating activity of IFN-gamma with respect to the bactericidal activity of monocytes.

Abstract
The effects of lung cancer on the abilities of blood monocytes to produce interleukin-1 and to mediate antitumor activity were examined. The functional integrity of blood monocytes was determined by their capacity to respond in vitro to a variety of activating agents and become tumoricidal, as assessed by a radioactive release assay and ability to produce interleukin-1 in vitro. The results show that the presence of lung cancer significantly increased the number of harvested blood monocytes and that the spontaneous tumoricidal activity of these monocytes was slightly high as compared to monocytes obtained from healthy donors. The production of interleukin-1 by monocytes of healthy donors and lung cancer patients was similar. Blood monocytes obtained from lung cancer patients were less cytotoxic against allogeneic A375 melanoma cells as compared with those of healthy donors subsequent to incubation with a soluble muramyl dipeptide analog or lipopolysaccharide, but were as tumoricidal as those from healthy donors when activated with lipophilic muramyl tripeptide (MTP-PE) entrapped in multilamellar liposomes. The finding that monocytes of patients with lung cancer can respond to MTP-PE encapsulated in liposomes, recommends the use of these liposomes in therapy of human lung cancer.

Abstract
The influence of immunotherapy with high dose (50 X 10(6) units/m2) recombinant leukocyte A interferon on blood monocyte functions was studied in eight patients with bronchogenic carcinoma. Monocyte chemotactic responsiveness (MCR) was initially depressed (9.8 +/- 1.6 cells/field) compared to healthy controls (17.6 +/- 5.1 cells/field), P less than 0.01. Recombinant interferon was administered three times weekly, and after 7 days a significant improvement in chemotaxis was observed (16.6 +/- 3.0 cells/field), P less than 0.05. The MCR remained normal until cessation of interferon therapy (greater than 1 month). Phagocytic and candidacidal activities were normal in the patients and were not influenced by treatment with interferon. In conclusion, high dose recombinant interferon given to cancer patients caused a normalization of defective blood monocyte chemotaxis, which persisted for greater than 1 month.

Abstract
Immunologic parameters were examined preoperatively in 104 patients with breast cancer, staged according to the TNM classification and in 95 age-matched healthy women. The immunologic evaluation in the peripheral blood included lymphocyte and monocyte counts, determination of E-rosette-forming T-lymphocytes (SER+) and B-lymphocytes (MER+), T-lymphocyte subsets defined with monoclonal antibodies (Leu-1, Leu-2a, Leu-3a) and with lectin fractionation (soybean agglutinin), lymphocyte transformation test with phytohemagglutinin (PHA) and concanavalin A (ConA), and colony formation of T-lymphocytes in agar (T-lymphocyte colony-forming cells, [TL-CFC]). Two age groups (Group A: 30-50 years; Group B: 51-70 years) and the different tumor stages (Stage I-IV) were analyzed. Patients and controls did not differ in the absolute numbers of lymphocytes, T- and B-cells. In patients of Group B, the absolute number of monocytes was increased slightly in Stage II and III and significantly in Stage IV (P less than 0.05). Similarly, the lymphocyte response to PHA was significantly reduced in Stage IV Group B only (P less than 0.05). ConA-induced lymphocyte proliferation and TL-CFC capacity were not different in patients and controls. In the small number of patients and age-matched controls in whom T-lymphocyte subsets were determined, the absolute numbers of T-cells with helper or suppressor phenotype as defined with Leu-3a, Leu-2a, or lectin fractionation with soybean agglutinin were similar. This study demonstrates that in patients with early breast cancer (Stage I-III), immunocompetence as defined by either functional in vitro studies or surface marker analysis is not significantly altered at the time of diagnosis. In contrast, patients with advanced disease (Stage IV) show a significant increase in the absolute number of monocytes and a depressed PHA responsiveness of mononuclear cells.

Abstract
Selected functions (i.e. phagocytosis and chemotaxis of circulating blood monocytes were studied on cells obtained from 20 patients with untreated multiple myeloma (MM) and the results were compared with those obtained on cells from 60 healthy persons. The mean number of circulating monocytes was only slightly increased over the normal value although a marked monocytosis was demonstrated in all of the 4 patients with M-components of the lambda light chain type. Plasma cells isolated from peripheral blood and from bone marrow of patients with MM were found to possess a strong alpha-naphthyl acetate esterase activity. No differences were observed in the phagocytic activity of monocytes from patients compared with those of the controls, whereas the chemotactic responsiveness of the monocytes from the patients was slightly increased.

Abstract
The interface between the tumor and the host is often the site of leucocytic infiltration. We will examine the idea that the infiltrating leucocytes of human and experimental tumors are components of the host immunological defense against the tumor, and that the presence of the infiltrate is a marker of favorable prognosis. Leucocytes could infiltrate tumors because of an active immune response, either nonspecific or specifically directed to tumor-associated antigens. Leucocyte influx may also occur because of chemotactic factors secreted by the tumor cells. Some tumors release factors which enhance vascular permeability and permit improved access by leucocytes to the tumor focus. The consequences of leucocytic infiltration include tumor cell cytolysis, cytostasis, or stimulation of proliferation. The present state of our knowledge of the interactions between tumor cells and infiltrating leucocytes precludes broad generalization of mechanisms. Further study will probably reveal that the mechanisms are diverse, and that there are some systems in which immune interactions occur at this interface and others in which they do not.

Abstract
Antibody-dependent cellular cytotoxicity (ADCC) mediated by peripheral blood monocytes was determined in 120 patients who had gastrointestinal tract (GIT), lung and breast cancer, melanoma, or Hodgkin's and non-Hodgkin's lymphoma. Results were expressed in terms of maximum cytotoxicity and cytotoxicity at E:T = 1:10 and were compared with the results obtained in 63 normal subjects. There was a significant decrease in maximal cytotoxicity for both the GIT cancer and the melanoma patient groups, but not for any of the other groups. These differences were not confirmed when results were expressed at low effector: target cell ratios, e.g., cytotoxicity at E:T = 1:10. The relationship between monocyte ADCC and disease extent was examined in those groups with sufficient numbers. Monocyte ADCC was higher in patients with GIT cancer of limited extent than in patients with extensive GIT cancer and in the control group.
