Abstract
Interferons (IFNs) form a family of cytokines with pleiotropic effects that modulate the immune response against multiple challenges like viral infections, autoimmune diseases, and cancer. While numerous anti-tumor activities have been described for IFNs, IFNs have also been associated with tumor growth and progression. The effect of IFNs on apoptosis, angiogenesis, tumor cell immunogenicity, and modulation of immune cells have been largely studied; however, less is known about their specific effects on cancer stem cells (CSCs). CSCs constitute a subpopulation of tumor cells endowed with stem-like properties including self-renewal, chemoresistance, tumorigenic capacity, and quiescence. This rare and unique subpopulation of cells is believed to be responsible for tumor maintenance, metastatic spread, and relapse. Thus, this review aims to summarize and discuss the current knowledge of the anti- and pro-CSCs effects of IFNs and also to highlight the need for further research on the interplay between IFNs and CSCs. Importantly, understanding this interplay will surely help to exploit the anti-tumor effects of IFNs, specifically those that target CSCs.

Abstract
INTRODUCTION Interferons (IFNs) play a key role in modulating anti-microbial and antitumor immune responses. In oncology, past attempts to exploit IFNs therapeutically did not fulfill expectations, and had only modest clinical results, mostly limited to adjuvant melanoma treatment. The recent successes of immunotherapy in oncology have brought new attention to the potential of immune-modulatory agents like the IFNs. Areas covered: The authors review the biological effects of IFN on melanoma and immune cells. Then, the authors summarize the clinical results of adjuvant and therapeutic IFN in melanoma, giving focus to possible prognostic factors and new on-going clinical trials. Expert opinion: IFNs offer intriguing opportunities for synergism between conventional treatments and recently introduced molecular-targeted and immunotherapy approaches. However, the full comprehension of all IFN effects and their multiple biologic links is challenging. A strong commitment toward parallel translational research is needed to facilitate the interpretation of IFN's expected and unexpected effects, guiding the rational design of informative clinical studies.

Abstract
Interferons (IFNs) are a family of naturally existing glycoproteins known for their antiviral activity and their ability to influence the behavior of normal and transformed cell types. Type I Interferons include IFN- α and IFN- β . Currently, IFN- α has numerous approved antitumor applications, including malignant melanoma, in which IFN- α has been shown to increase relapse free survival. Moreover, IFN- α has been successfully used in the intralesional treatment of cutaneous squamous cell carcinoma (SCC) and basal cell carcinoma (BCC). In spite of these promising clinical results; however, there exists a paucity of knowledge on the precise anti-tumor action of IFN- α / β at the cellular and molecular levels in cutaneous malignancies such as SCC, BCC, and melanoma. This review summarizes current knowledge on the extent to which Type I IFN influences proliferation, apoptosis, angiogenesis, and immune function in normal skin, cutaneous SCC, BCC, and melanoma.

Abstract
NK cells are effector lymphocytes playing a critical role in the natural resistance against tumors. However, the precise mechanisms underlying NK cell-mediated natural resistance against tumor metastasis are still unrevealed. B16 cells, mouse melanoma cells, were resistant to freshly isolated NK cell-mediated killing; nevertheless, NK cells were critical for natural resistance against experimental lung metastasis of B16 cells. We found that lung metastasis was increased significantly in IFN-γ(-/-) mice but not pfp(-/-), IFN-αR(-/-), or IL-12/IL-18(-/-) mice. Interestingly, freshly isolated lung NK cells, but not spleen or liver NK cells, displayed augmented IFN-γ production after B16 inoculation. Adoptive transfer of pfp(-/-) NK cells, but not IFN-γ(-/-) NK cells, significantly decreased B16 lung metastasis in IFN-γ(-/-) and pfp/IFN-γ(-/-)mice. Lung metastases of IFN-γRDN B16 was also increased in NK cell-depleted or IFN-γ(-/-) mice, suggesting that the IFN-γ response of host cells was required in the NK cell and IFN-γ-mediated antimetastatic effect. Our results demonstrate that IFN-γ production from lung resident NK cells is a key response in the natural resistance to the experimental lung metastasis of NK cell-resistant tumor cells.

Abstract
IFN-gamma has a profound influence on growth and metastasis of solid tumors. This is true for the murine mammary carcinoma 4T1 which grows faster and metastasizes much more readily when transplanted into the mammary fatpads of IFN-gamma(-/-) mice. We were interested in determining which infiltrating hematopoietic cells produce IFN-gamma within the 4T1 tumor microenvironment. 4T1 tumors were infiltrated with progressively increasing numbers of F4/80(+)/CD11c(+) myeloid cells, many of which were also Gr-1(+), and Gr-1(+)/CD11b(+) granulocytes. Only small numbers of CD4 T cells, CD8 T cells, NK cells, and gammadelta T cells, the most likely IFN-gamma-producing cells, were seen at any time point. Sensitive intracellular cytokine staining and flow cytometry revealed no tumor-infiltrating hematopoietic cells with detectable levels of intracellular IFN-gamma, although IFN-gamma mRNA transcripts were detected in tumor tissue. However, a progressive increase in the expression of three IFN-gamma-inducible surface membrane proteins (B7-H1, I-A(d), and ICAM-1) on growing 4T1 tumor cells indicated the presence of biologically active IFN-gamma in the tumor microenvironment. Moreover, 4T1 tumor cells from in vitro culture expressed these surface molecules 48 h after intratumoral injection into mature tumors. These data suggest that very low amounts of endogenous IFN-gamma elaborated by infiltrating hematopoietic cells within the microenvironment of a solid tumor can achieve biologically active concentrations and affect tumor phenotype, growth, and metastasis.

Abstract
In murine tumors, innate immunity act as a trigger for the development of acquired immunity. The innate immune cells, natural killer (NK) and natural T (NKT) cells, generate the acquired immune cells, cytotoxic T lymphocytes (CTLs) and T helper (Th) 1 cells, by releasing interferon (IFN)-gamma. Regulatory T cells co-infiltrate with these tumoricidal effectors. In the innate phase, T cell receptor (TCR) gammadelta-bearing T (gammadelta T) and TCRalphabeta intermediate T cells are the regulators that suppress NK and NKT cells by elaborating interleukin (IL)-4, IL-10 and transforming growth factor (TGF)-beta. The acquired phase has Th3/T regulatory 1-like cells that inhibit CTLs and Th1 cells by TGF-beta. Thus, cytokines from regulatory T cells exert profound effects on tumor growth.

Abstract
A previous study by our laboratory showed that the peritoneal murine Corynebacterium parnum-elicited macrophages released into their growth medium an activity which enhanced the ability of B16-F10 melanoma cells to form experimental metastases in the lung of syngeneic mice. In the present study, we used a clone of B16-F10 line (F10-M3 cells) to investigate whether the increase in lung-colonizing potential due to the pro-clonogenic activity released by C. parvum-elicited macrophages was associated with biological properties characteristic of a metastatic phenotype. We have found that the pulmonary retention, growth rate in lung parenchyma, invasiveness through Matrigel, adhesiveness to IL-1-activated endothelium and MHC class I expression were increased in F10-M3 cells stimulated by the macrophage pro-clonogenic activity. By using an in vitro experimental protocol, the enhancement of lung-colonizing potential in the stimulated melanoma cells turned out to be a transient phenomenon as was the increase of invasiveness through Matrigel and the higher expression of MHC class I antigens. In conclusion, the melanoma cells stimulated by the pro-clonogenic activity released by C. parvum-elicited macrophages showed changes in biological parameters which are relevant to metastatic diffusion. These changes appeared as a temporary phenomenon which sustains the view that the metastatic phenotype represents a transient biological character influenced by host factors.

Abstract
It has been thought that natural killer (NK) cells appearing early in tumor lesions play a pivotal role in the innate immunity against tumor cells. Although NK cells serve as the first tumoricidal effector cells, they subsequently promote a shift in effectors from themselves to tumor-specific cytotoxic T lymphocytes (CTLs) that mediate the acquired immunity. The mechanism of this shift has not been fully elucidated, however, NK cell-derived T helper (Th) 1 cytokines such as interferon (IFN)-gamma seem to play a key role. Another NK-lineage, termed natural killer T (NK T) cells, may also participate in the innate period when they acquire the ability to secrete Th1 cytokines. Interleukin-4 (IL-4) and IL-10, belonging to Th2, and transforming growth factor-beta (TGF-beta), belonging to T regulatory (Tr) 1 cytokines, are known to suppress the development of NK, NK T cells, as well as CTLs and to block Th0 cell differentiation to Th1 cells, suggesting that tumor cells can evade the innate and acquired immunity by virtue of cells producing these inhibitory cytokines. In early tumor lesions of murine B16 melanoma, gammadelta T and alphabeta intermediate (int) T cells that co-infiltrate with NK and NK T cells can produce Th2 cytokines and inhibit the innate immunity. In MM2 mammary tumor-bearing mice, gammadelta T cells appearing both lesionally and systemically secrete Tr1-type cytokines and depress the acquired immunity. These Th2- or Tr1-type gammadelta T and alphabeta(int) T cells downregulate the tumoricidal cells by means of both their secreted cytokines and express major histocompatibility complex (MHC) class I molecules.

Abstract
S100A4 belongs to the S100 subfamily of calcium-binding proteins and has been suggested to be directly involved in invasion and metastasis of rodent and human tumour cells. The present study demonstrates that interferon gamma (IFN-gamma), but not IFN-alpha and IFN-beta, down-regulates the S100A4 mRNA level in colon adenocarcinoma WiDr cells in time- and dose-dependent manners. The effect was not associated with any cytotoxicity and was specific for the S100A4 mRNA, since the levels of the S100A6 and GAPDH mRNAs were not significantly affected by the treatment. IFN-gamma also strongly suppressed the S100A4 mRNA expression in HT-29 cells, but weakly in Colo201 cells. Flow cytometric analysis revealed that the level of the IFN-gamma receptor expression in Colo201 cells was lower than that in WiDr and HT-29 cells, suggesting that the suppression of the S100A4 expression by IFN-gamma depends on the amount of cell surface IFN-gamma receptor protein. IFN-gamma had no effect on the transcription rate of the S100A4 gene but reduced the stability of the S100A4 mRNA. WiDr cells treated with IFN-gamma showed reduced motile ability, further supporting the assumption that the S100A4 gene product is involved in controlling cell motility.

Abstract
Abstract
We examined whether γδ T and αβ T cells accumulating in early B16 melanoma lesions regulate NK and NK T cells that attack tumor cells. Freshly isolated and cultured tumor-infiltrating lymphocyte (TIL) populations of NK and NK T cells lysed B16 and produced IFN-γ, whereas γδ T and a large part of αβ T cell populations had no substantial cytotoxicity against B16 and secreted Th2 cytokines. Furthermore, the freshly isolated NK1.1+ TIL population exhibited a higher anti-B16 effect than did splenocytes. γδ T and αβ T cell populations dramatically inhibited the cytotoxicity of NK and NK T cells in an MHC Kb-dependent manner. Culture supernatant from γδ T and αβ T cell populations inhibited the proliferation of NK and NK T cell populations but did not affect their cytotoxicity, suggesting that the released Th2 cytokines are merely partly involved in the down-modulation of NK-lineage cells. NK1.1+ cells obtained from TIL of γδ T cell-depleted mice significantly lysed B16 cells compared with those from control mice. Finally, anti-Kb Fab mAb injected intralesionally at an early, but not at a late, stage of development of B16 melanoma inhibited tumor growth. These findings suggest that Th2-type γδ T and αβ T cells infiltrating in early B16 development inhibit the tumoricidal activity of NK-lineage cells using their class I molecules and partly their suppressive cytokines.

Abstract
Various factors that modulate the differentiation of malignant cells are known to affect their experimental metastatic potential (EMP), or lung colonization after intravenous injection into syngeneic animals. However, some results and conclusions on the relation between cell differentiation and metastasis have appeared to conflict. We have reanalysed this by measurement of EMP of B16 melanoma sublines after culture with agents or conditions that acted on differentiation through various intracellular pathways. All tested agents did affect the EMP. EMP was usually positively correlated with differentiation under diverse conditions, but exceptions showed that there is no direct causal connection. Nor could all findings be explained in terms of cell proliferation or expression of major histocompatibility antigens. Some data helped to explain disparities between previous reports. Specific novel findings included the following. The stimulation of EMP by melanocyte-stimulating hormone (MSH) as well as all other tested effects of MSH were prevented by extended exposure to 12-O-tetradecanoyl phorbol acetate (TPA), suggesting a requirement for protein kinase C activity as well as G-protein coupling in MSH action. Cells grown with cholera toxin were always more differentiated than untreated cells, but the EMP could be either markedly increased or markedly decreased by cholera toxin under different conditions. The basic culture medium apparently determined this striking reversal. The EMP was also significantly affected by the extracellular pH.

Abstract
Poorly liver metastatic large-cell lymphoma RAW117-P cells were sequentially selected in vitro for increased adhesion to murine hepatic sinusoidal endothelial cells. After three or four sequential selections, the selected sublines showed increased rates of adhesion to target hepatic microvessel endothelial cells and increased formation of experimental metastases in the liver. However, the endothelial cell adhesion-selected RAW117 sublines were generally unstable and gradually lost their enhanced adhesive and metastatic properties during passage in culture. Highly metastatic, liver-selected RAW117-H10 large-cell lymphoma cells were more resistant to the cytostatic effects of interferon-gamma (IFN-gamma) than poorly metastatic unselected parental RAW117-P cells. When tested for their sensitivity to IFN-gamma, the endothelial cell adhesion variants were significantly more resistant than the unselected RAW117-P cells, but after a 72-h treatment with IFN-gamma, the in vitro-selected cells lost their enhanced endothelial cell adhesion characteristics, their potential to colonize the liver, and their ability to grow when injected at subcutaneous or intramuscular sites. In contrast, the metastatic potential of similarly treated RAW117-P cells was unaffected by IFN-gamma during a 72-h treatment. Sequential selection of RAW117-P cells for increased resistance to IFN-gamma in vitro resulted in variant lines that were refractory to the growth-inhibiting effects of IFN-gamma, and these IFN-gamma-selected variants were also less adhesive to liver microvessel endothelial cells. The IFN-gamma-selected variants also lost their experimental metastatic potentials completely and their tumorigenicities at sites of subcutaneous or intramuscular injection. Cytofluorographic analysis indicated reduced cell surface expression of H-2Kd antigen and fibronectin receptor on the selected variant cells but no change in cell surface mu heavy chain immunoglobulin. The unselected and selected RAW117 lines had similar sensitivities to natural killer (NK) cell-mediated cytolysis, indicating that the in vivo differences were probably not due to differences in NK cell-mediated cytolysis. The results suggest that selection for adhesion to organ microvessel endothelial cells or sequential exposure to certain cytokines can affect the adhesive, growth and metastatic properties of RAW117 cells without modifying their responses to NK cells.

Abstract
Highly metastatic, in vivo-selected cells of RAW117-H10 large-cell lymphoma have been shown to be more resistant than poorly metastatic parental RAW117-P cells to the cytolytic and cytostatic activities of activated macrophages in co-culture experiments. Activated macrophages are known to produce soluble, cytostatic respiration-inhibiting factors, and such activities can be duplicated by interferon-gamma (IFN-gamma) or by combinations of IFN-gamma and Escherichia coli lipopolysaccharide (LPS). Highly metastatic RAW117-H10 cells are more resistant to the cytostatic effects of IFN-gamma and LPS than poorly metastatic RAW117-P cells, and short-term (up to 72 hr) treatment with IFN-gamma and LPS does not change the metastatic potentials of RAW117 cells. We have studied the effects of sequential selection of RAW117-P cells for increased resistance to IFN-gamma and LPS. After 7 to 13 sequential selections, the resulting variant lines were completely refractory to the growth-inhibitory effects of IFN-gamma and LPS and cross-tolerant to macrophage-conditioned medium. The selected variants also completely lost their experimental metastatic potentials and their tumorigenicities after s.c. or i.m. injection. Cytofluorographic analysis indicated reduced cell-surface expression of H-2Kd antigen and fibronectin receptor on the variant cells but no change in surface mu heavy-chain immunoglobulin. The IFN-gamma-selected lines were less adhesive to liver microvascular endothelial cells than the unselected RAW117 cell lines, but were equally sensitive to NK cytolysis by spleen cells. Our results suggest that exposure to certain cytokines can affect the growth and metastatic potential of RAW117 cells and result in the selection of resistant variants with altered biologic properties.

Abstract
Tumour necrosis factor alpha (TNF) is a multipotent cytokine which affects many biological properties of both normal and neoplastic cells. Here we show that treatment with TNF reduces B16-A melanoma cell susceptibility to normal and in vivo- and in vitro-activated NK cell-mediated killing. This resistance is associated with an enhancement of B16-A metastatic potential in normal syngeneic mice, but not in anti-asialo GM1-treated animals, further supporting the NK dependence of TNF-induced enhancement of metastatic ability. A significant increase of MHC class I expression on B16-A murine melanoma cells is observed after TNF treatment. In all these effects TNF interacts positively with interferon gamma (IFN gamma). Taken together, these results indicate that TNF treatment negatively affects the susceptibility of B16-A murine melanoma to NK effectors in vivo and in vitro. This decreased susceptibility may be related, at least in part, to enhanced expression of MHC class I antigens on tumour cells.

Abstract
The H-2b-negative B78HI clone (derived from B16 melanoma) was transfected with the H-2Kb gene; 4 cell clones expressing membrane H-2Kb antigens and 2 control clones (transfected with pSV2neo alone) were used for studies of metastatic ability, immunogenicity, NK sensitivity and homotypic adhesion. The experimental metastatic capacity of H-2Kb transfectants in syngenic mice was greatly diminished in comparison with control and parent cells. Both immune-mediated and intrinsic properties of transfectants correlated with their lower metastatic ability. A cell-mediated cytotoxic response was induced by repeated in vivo immunizations of syngeneic mice followed by in vitro restimulation of effectors when transfectants (but not controls) were used as immunizers and as targets. Moreover, homotypic adhesion of H-2Kb transfectants was significantly lower than that of controls. Sensitivity to NK cells of transfectants was not decreased in comparison to H-2-negative controls. It is known that in vitro treatment with IFN-gamma of H-2-positive B16 melanoma cells induces a simultaneous increase in H-2 expression and in experimental metastasis; treatment of H-2Kb transfectants with IFN-gamma induced a higher Kb expression, but no increase in metastatic ability, thus suggesting that the IFN-sensitive component that mediates enhancement of metastasis is not H-2Kb.

Abstract
B16-F10.9 is a highly metastatic clone of the B16-F10 melanoma line, that expresses low levels of MHC class-I antigens. F10.9 cells transfected with H-2Kb are highly immunogenic and consequently exhibit a low metastatic phenotype. Treatment with gamma-IFN elevated H-2Kb and H-2Db cell surface expression of F10.9 cells to levels much higher than did transfection of these genes. Yet, following intravenous injection, the gamma-IFN treated cells generated high loads of lung metastases. However, when tested for their immunogenic effect, they elicited CTL and were sensitive to CTL. Immunization with both the positive transfectant KI and the gamma-IFN-treated F10.9 cells protected in vivo against metastatic spread of a subsequent transplant of parental F10.9 cells. The protection elicited by KI transfectants was more effective than the protection by gamma-IFN-treated cells.

Abstract
Interferon treatment increases the ability of tumour cells to colonize the lungs. Although it has been suggested that this effect can be explained by increases in the expression of MHC molecules the precise mechanism is still uncertain. The growth in the lungs of a low (F1) and a high colonizing variant (BL6) of the B16 mouse melanoma have been studied after in vitro treatment with interferon. Interferon-gamma, but not interferon-alpha/beta, increased the number of lung colonies formed after intravenous injection, but not after subcutaneous administration. Treatment also increased the sizes of the lung colonies formed and the number of radiolabelled cells retained by the lungs. However, no clear relationship was observed between the number of colonies formed and the concentration of interferon used. The effect of interferon on F1 was greater than on BL6, but the overall number of colonies formed was very similar. These results suggest that interferon increases the adhesiveness of these cell lines in a fairly non-specific manner, that seems unlikely to involve MHC molecules. As a results of this and other studies the importance of interferon in the process of tumour spread seems very questionable.

Abstract
Natural killer (NK) cells can defend an organism against a variety of threats, probably using several different strategies to discriminate between normal and aberrant cells. According to the 'missing self' hypothesis, one function of NK cells is to recognize and eliminate cells that fail to express self major histocompatibility complex (MHC) class I molecules. In this article Hans-Gustaf Ljunggren and Klas Kärre review in vivo studies with H-2-deficient targets that support this hypothesis. In vitro studies, some of which have given conflicting results, are interpreted within a multiple choice model for NK cell recognition. The authors derive testable predictions for how MHC class I molecules act in cases where they control a rate-limiting step in the NK cell-target interaction.

Abstract
The effects of recombinant tumor necrosis factor-alpha (TNF-alpha) and interferon-gamma (IFN-gamma) on B16 mouse melanoma experimental metastatic ability and major histocompatibility complex (H-2b) antigens expression were studied. B16 cells exposed in vitro to TNF-alpha had an increased H-2 expression and were more metastatic than untreated cells. The simultaneous treatment with TNF-alpha and IFN-gamma amplified the enhancement of experimental metastasis and all other effects obtained with TNF-alpha alone. The B16 clone B78H1, selectively resistant to H-2 induction and to enhancement of metastatic ability by IFN-gamma, was not affected by treatment with TNF-alpha and with TNF-alpha + IFN-gamma. These findings contribute to a better understanding of the pleiotropic effects of TNF, some of which can have opposing actions in the complex tumor-host relationships.

Abstract
Several reports have suggested that an inverse correlation exists between major histocompatibility complex class I expression and the susceptibility to natural killer (NK)-mediated lysis. For example, the increased class I expression induced by interferon-gamma was always accompanied by an increased resistance to NK lysis. Likewise, class I loss variants were often more NK susceptible than their normal counterparts. To investigate whether the inverse correlation between class I expression and NK susceptibility was fortuitous or whether the class I molecules were directly responsible for this effect we resorted to gene transfection studies. From the murine thymoma line EL4 and H-2Db- and Kb-negative variant S3 was selected. This variant was highly susceptible to NK lysis. S3 was found to have a defect in beta 2-microglobulin gene expression. Therefore, restoration of Db and Kb expression could be achieved by transfection with the beta 2-microglobulin gene. This resulted in a strong decrease in susceptibility to NK lysis to the level of the H-2+ parental EL4. Transfection with class II genes had no effect. Blocking of the class I molecules on the H-2+ cells with anti-H-2b F(ab')2 fragments increased the susceptibility to NK cells to the level of the H-2- variant S3. These data demonstrate that the class I molecules on the targets are directly responsible for regulation of NK susceptibility but the mechanism is not clear. Possibly the class I molecules interfere with the unknown NK target structures.

Abstract
The Membrane Invasion Culture System (MICS) assay was adapted for relatively rapid screening of compounds and used to identify anti-invasive drugs that inhibit human and murine tumor cell migration through a reconstituted basement membrane in vitro. Cell lines demonstrating low and high invasive and metastatic potentials were tested with all compounds for tumoricidal effects prior to evaluation in MICS at non-cytotoxic doses. The effect on invasive potential in the MICS assay was determined in 3 categories: (1) 48 hr drug pre-treatment prior to seeding in the MICS (exceptions: 90 min pre-treatment with pertussis toxin and, for some studies, continuous exposure for 2-7 days); (2) peptide or prostaglandins 2 hr after seeding and attachment to the membranes in MICS followed by continuous exposure; and (3) cells receiving neither drug nor peptide treatment and serving as controls in each MICS chamber. Since invasion involves cellular motility and deformability, some cytoskeleton disrupting agents were selected. Of these, vincristine, colcemid and colchicine inhibited invasion but taxol did not. Pre-treatment with cAMP agonists produced conflicting results: dibutyryl cAMP and 8-(4-chloro-phenylthio) cAMP resulted in 50% and 38% reduction in invasion, respectively, whereas 8-bromo cAMP stimulated invasive potential by 30%. Forskolin and cholera toxin both significantly reduced invasiveness. Pre-treatment with 5-azacytidine and araC, to consider the role of methylation and proliferations decreased invasive ability. Anti-metastatic drugs such as gamma-interferon and razoxane inhibited invasive potential but to varying degrees. Treatment of cells with prostaglandins E2, F2 alpha, A2, and D2 were ineffectual; however, indomethacin mildly inhibits invasion (less than 30%).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
HLA antigen-loss mutants and class I gene transferents were used to analyze the influence of class I expression on natural killer (NK) cell-mediated lysis. Only HLA antigen-loss mutants that had lost expression of either HLA-A and HLA-B antigens (mutant .184) or of HLA-A, B and C antigens (mutant .221) were distinctly susceptible to NK-mediated lysis. Mutants with reduced expression of class II antigens but unaltered expression of class I antigens remained resistant to NK lysis. A direct demonstration of the effect of class I antigen expression on human cells was made by analyzing a variety of gene transferents of the HLA-A, B, C null mutant .221 expressing only one transferred HLA-A, B or C gene. These results specifically show that expression of class I antigens, with a possible preferential effect of HLA-B expression, reduces the susceptibility of mutant .221 to NK-mediated lysis.

Abstract
From the studies summarized here a complex picture of the role played by MHC products in determining tumorigenicity and metastasis is emerging. In order to be able to understand this relationship better, it is necessary to consider several factors. 1. Each tumor system or neoplastic tissue is unique, and its behavior reflects the influence of cell-specific characteristics, as well as its ability to modulate other cells and tissues--including cells belonging to the immune system--and also to be modulated by other cells and soluble factors. 2. Since metastasis formation is a multistep process in which only small subpopulations of tumor cells with complex and defined phenotypes are able to colonize secondary tissues, elimination of even one single phenotypic component of this structured process can easily reverse the metastatic capacity of the cells. Acquisition of metastatic ability, on the other hand, would be a more difficult task, since any new characteristic expressed by the cells or induced experimentally, such as gene transfection or results of IFN treatment, must be expressed in a temporal manner and in concert with other cellular characteristics. Therefore, an experimental protocol measuring a specific element in determining metastasis can easily produce conflicting results, depending on the type of cells and genetic background of the host studied. 3. The level of specific MHC products on tumor cells is one among many other cell characteristics that may determine the metastatic potential of cells. Moreover, each of the class 1 MHC products, and the relationship among them, including other than the classical K, L, or D products (Brickell et al., 1983), should be regarded as independent entities, with possible different regulatory roles in cell-cell recognition, in a general sense, which may be involved in determining invasiveness and homing as well as recognition by the immune system. 4. Both specific T-cell and nonspecific natural mediated immunity (which is much less understood) are involved in the selection of the metastatic cell population. 5. Immunogenicity of tumors is not necessarily determined by high levels of MHC antigen expression; it is also dependent on the level of TSA. Thus, immunoselection mediated by T lymphocytes during metastasis formation could be directed against both MHC and TSA antigens. Therefore, low expression of MHC antigens by metastatic cells as a result of immunoselection is not always observed.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
The melanoma-associated antigen P3.58 is rarely found on benign proliferating melanocytes but is consistently expressed on advanced malignant melanomas which have a high probability of metastasis. Previous studies have shown that its expression on normal tissues is limited to vascular endothelia and lymphoid follicle germinal centers and that it is also expressed by activated monocytes in vitro. In the studies reported here, anti-P3.58 monoclonal antibodies (mAb) were shown to partially inhibit antigen-specific and anti-CD3-induced T cell proliferation and to completely block a lymphocyte/monocyte clustering which occurs in the absence of added antigen. This inhibition is highly specific for P3.58 mAb and was not affected by mAb directed to major histocompatibility complex or T cell antigens. P3.58 therefore seems to be involved in an antigen-independent attraction or adhesion of lymphocytes. P3.58 is the second example (HLA-DR being the first) of an association between the expression of an immune function-associated molecule and the development of metastatic disease in melanoma.

Abstract
Interleukin-2 (IL-2)-activated killer (LAK) cells specifically lyse human monocytes, which may account for some of the toxicity seen during LAK/IL-2 immunotherapy of cancer patients. In an effort to protect autologous monocytes, we treated monolayer cultures of monocytes with various doses of recombinant human interferon-gamma (IFN-gamma) and assessed their sensitivity to LAK-mediated lysis. IFN-gamma lessens the sensitivity of monocytes to lysis in a dose-dependent manner. Treatment of FMEX, an NK-resistant melanoma tumor cell line, with IFN-gamma did not affect its susceptibility to LAK lysis. Kinetic studies demonstrated that as little as 2 hr incubation with IFN-gamma was sufficient for protection to occur, and that monocytes which were treated with IFN-gamma for 2 hr, washed, and then cultured in medium alone retained their resistance to lysis for at least 4 days. Cold target inhibition studies showed that IFN-treated and untreated monocytes could effectively compete with each other for binding sites on LAK cells. Finally, binding studies demonstrated that there was no significant difference between the number of conjugates formed using either IFN-treated or untreated monocytes. This indicates that resistance to lysis induced by IFN treatment affects a post-binding event and not an initial recognition signal.
