Abstract
We have generated, via somatic cell nuclear transfer, two independent lines of transnuclear (TN) mice, using as nuclear donors CD8 T cells, sorted by tetramer staining, that recognize the endogenous melanoma antigen TRP1. These two lines of nominally identical specificity differ greatly in their affinity for antigen (TRP1(high) or TRP1(low)) as inferred from tetramer dissociation and peptide responsiveness. Ex vivo-activated CD8 T cells from either TRP1(high) or TRP1(low) mice show cytolytic activity in 3D tissue culture and in vivo, and slow the progression of subcutaneous B16 melanoma. Although naïve TRP1(low) CD8 T cells do not affect tumor growth, upon activation these cells function indistinguishably from TRP1(high) cells in vivo, limiting tumor cell growth and increasing mouse survival. The anti-tumor effect of both TRP1(high) and TRP1(low) CD8 T cells is enhanced in RAG-deficient hosts. However, tumor outgrowth eventually occurs, likely due to T cell exhaustion. The TRP1 TN mice are an excellent model for examining the functional attributes of T cells conferred by TCR affinity, and they may serve as a platform for screening immunomodulatory cancer therapies.

Abstract
We previously found that chronic alcohol consumption (20% w/v in drinking water) that models the level consumed by human alcoholics, when administered to female C57BL/6 mice inhibits B16BL6 melanoma metastasis to the lung; however, the mechanism is not known. Chronic alcohol consumption increases IFN-γ producing NK, NKT, CD4(+), and CD8(+) T cells. To examine the impact of IFN-γ on metastasis, we inoculated B16BL6 melanoma cells i.v. into control and chronic alcohol drinking IFN-γ knockout (KO) mice. Knockout of the ifn-γ gene abrogated the anti-metastatic effects associated with alcohol consumption. We examined metastasis in common gamma-chain (γC) KO mice, which are deficient in NK, NKT and CD8(+) T cells, and in Vα14Jα281(-/-) KO mice, which are deficient in invariant NKT (iNKT) cells, in order to assess the importance of specific IFN-γ producing cell types to this effect. We found that the antimetastatic effect of alcohol was still present in γC KO mice and also in γC KO mice depleted of Gr-1(+) cells. Knockout of iNKT cells reduced the degree but not the antimetastatic effect associated with alcohol. These results indicate that the antimetastatic effect induced by chronic alcohol consumption is IFN-γ dependent and that multiple IFN-γ producing cell types contribute to this effect.

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
Circulating immune markers sICAM-1, sELAM-1, sMHC-I, beta 2-MG, sCD4 and sCD8 were evaluated prior to and during immunotherapy with biologically active doses of interferon gamma (IFN-gamma) in 16 patients with advanced renal cell carcinoma (RCC) over a period of 12 months. Compared to 20 healthy controls, significantly (P < 0.01) elevated baseline levels of circulating adhesion molecules sICAM-1 (mean 1166 vs 230 ng/ml) and sELAM-1 (70 vs 17 ng/ml) were found in all patients. Compared to responders (n = 2) or patients with stable disease (n = 2), progressive disease during therapy (n = 12) was associated with significantly (P < 0.05) higher mean concentrations of sICAM-1 (1574 vs 962 ng/ml) and sELAM-1 (86 vs 46 ng/ml). Pretherapeutic and intratherapeutic levels of sMHC-I among the RCC patients were significantly (P < 0.05) lower than among the controls (0.41 vs 0.8 ng/ml). sCD4 levels clearly showed the same tendency (24 vs 33 U/l). sCD8 baseline levels, by contrast, were significantly (P < 0.05) elevated (564 vs 336 U/l), reflecting either activation of the NK-cell subset or increased synthesis of CD8+ T-suppressor cells. Again, significantly (P < 0.05) higher intratherapeutic sCD8 concentrations were observable with progressive disease than with response to therapy or stable disease (721 vs 355 U/l). Interestingly, although the biologically active dose of IFN-gamma was defined by an increase in beta 2-MG release of at least 30% within 48 h after injection, none of the other markers showed any significant alteration following IFN-gamma administration, suggesting that IFN-gamma in vivo does not produce changes in circulating markers of activation that might be expected on the basis of its effects in vitro. The finding of significantly elevated concentrations of sICAM-1, sELAM-1 and sCD8 in the presence of low sCD4 and sMHC-I levels might be of clinical significance for indicating ongoing tumor progression.

Abstract
Numerous tumors express low or no class I molecules, resulting in their avoidance of recognition and destruction by different effector cells of the immune system. Using a parent and two MHC class I mutant cell lines, we have tested the role of MHC class I molecules in natural killer (NK) cells, lymphokine activated killer (LAK) cells and cytotoxic T lymphocytes (CTLs). Both class I expressing parent cells and class I loss mutants were insensitive to NK cell lysis as assayed, regardless of the amount of class I molecules on the target cell surface. However, LAK cells demonstrated higher cytolysis on these target cells than NK cells, suggesting different mechanisms of target cell recognition or different levels of lytic activity by these two effector cell populations. Up-regulation of class I expression on the target surface by gamma interferon (gamma-IFN) had little influence on NK and LAK susceptibility, indicating there was no correlation between class I expression and bovine NK or LAK cytolysis. However, allogeneic CTLs mediated a lytic pattern distinct from NK and LAK cells, in which target sensitivity to allogeneic CTLs correlated with the amount of class I molecules expressed on the cell surface. Additionally, effector-target cell conjugation studies demonstrated that target class I expression was not involved in NK and LAK cells binding to targets. These results demonstrate that NK and LAK cytolysis of these two class I mutant cell lines is independent of the amount of class I molecules expressed on the target cell surface.

Abstract
Natural killer (NK) cells probably function as an early defense line against viruses because of their ability to kill virus-infected cells as well as a variety of tumor cells. In both cases, the killing is major histocompatibility complex (MHC)-unrestricted. NK cells exhibit spontaneous activity but they are positively regulated by interferons (IFNs) or indirectly by such IFN inducers as viruses, bacterial products, poly(rI):(rC), and mitogens. In addition to their "positive" regulation on NK activity, IFNs often act as "negative signals" for NK and lymphokine-activated killer (LAK) cell-mediated cytotoxicity. If NK susceptible target cells are exposed to IFN prior to NK cells, their sensitivity to NK activity is often markedly diminished. The mechanism by which IFNs (IFN-alpha, -beta, and -gamma) affect the sensitivity of target cells to NK activity remains unknown, but it is clear that this function is not shared by other cell-mediated killing processes. The protective effect induced by IFN against NK activity is dependent on new mRNA and protein synthesis and can be abolished when target cells are incubated with a combination of IFN and metabolic inhibitors or by chemotherapeutic purine or pyrimidine analogs. IFN treatment neither affects the conjugate formation between NK cell and target cell nor the susceptibility of target cells to NK cytotoxic factor (NKCF), released by effector cells. However, IFN reduces the capacity of target cells to induce activation of conjugated NK cells. Because IFN has the ability to induce or increase class I MHC antigen expression (on NK target cells), it has been suggested that class I MHC antigens act as "negative signals" or NK-mediated cytotoxicity. Although many studies support this hypothesis, others present evidence for a lack of involvement of class I MHC antigens in mediating sensitivity to NK activity. This review summarizes and discusses the dual effect of IFNs in the regulation of NK activity, the relationship between the expression of class I MHC antigens on target cell surface and sensitivity to NK activity following treatment with IFNs, and the possible clinical relevance of the dual effect of IFN.

Abstract
Female C57BL/6 mice were fed a defined, pelleted diet and given 10% w/v or 20% w/v ethanol in their drinking water. Natural killer (NK) cell cytolytic activity was compared between water-drinking and ethanol-consuming mice and in mice that were also treated with polyinosinic-polycytidylic acid (poly I:C) to augment NK cell activity or with anti-NK1.1 antibody to decrease activity. NK cell cytolytic activity was not altered in mice given 10% ethanol, but was decreased in mice given 20% ethanol compared to water-drinking mice. Poly I:C treatment increased and anti-NK1.1 antibody treatment decreased NK cell activity in both water-drinking and 20% ethanol-consuming mice. Experimental and spontaneous metastases of B16-BL6 melanoma were evaluated as a function of the duration of ethanol consumption before tumor inoculation and as a function of altered NK cell activity. Experimental metastasis was inhibited after 4 and also after 6.5 weeks of ethanol exposure. Poly I:C treatment inhibited tumor lung colonization irrespective of ethanol consumption. Anti-NK1.1 antibody treatment increased metastasis, although to a lesser degree in mice consuming 10% ethanol. Spontaneous metastasis was inhibited in mice consuming 10% ethanol for 4 weeks, and in mice consuming 20% ethanol for 1 and 4 weeks before melanoma inoculation.

Abstract
In the present study we investigated the effect of temperature on MHC class-I gene expression in BALB/C 3T3 cells incubated for 5 days at 34 degrees C, 37 degrees C and 39 degrees C. FACS analysis revealed no significant difference in the cell surface expression of any of the 3 major class-I antigens at 34 degrees C and 37 degrees C. Strikingly, however, when the level of the respective mRNA was determined, only that of the H-2K was comparable at both temperatures, whereas the levels of the H-2D and H-2L mRNA were profoundly higher at 37 degrees C. These data appear to reflect a differential temperature-related transcriptional control of the different class-I genes or a different temperature effect on the stability of their mRNA. The absence of a parallel increase in surface expression of the corresponding H-2D and H-2L antigens may result from some translational or post-translational limiting factors. At 39 degrees C, however, these limiting factors seem to be overcome since the surface expression of all the 3 antigens was remarkably increased although the level of their encoding mRNA was rather lower than in 37 degrees C. This stimulatory effect might be ascribed to heat shock proteins which are known to arise in cells at heat or other stress conditions. They participate in assembly and disassembly of various protein complexes and in transport of certain proteins across intracellular membranes. Such proteins may have arisen in our cells at 39 degrees C and facilitated the intracellular assembly of the class-I molecules and their transport to the cell surface. The possible implication of such heat shock proteins in the anti-tumor effect of hyperthermia is discussed.

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
Cell lines and a clone established from the C57BL/6 (H-2b) Lewis lung (3LL) tumour were previously characterized with respect to tumour growth and metastatic spread in vivo, and to the expression of a 3LL tumour-specific antigen (3LL TA) using a monoclonal antibody raised in syngeneic mice immunized with 3LL cells. No correlation was observed between the presence of 3LL TA and the prevention of metastatic spread which suggests that the immune recognition of this tumour antigen requires the presence of a self H-2 molecule absent from these tumour cells. Indeed, radioimmunoassay (RIA) and cytofluorometric analysis using specific monoclonal antibodies have shown that the H-2Kb molecule was not expressed at the cell surface of all 3LL cell lines and clones, while the H-2Db molecule was present at normal levels. This defect, which was not the consequence of a lack of beta 2m expression, was accompanied by an absence or a marked reduction of the H-2K mRNA level (which has been reversed in the M4 cell line by in vitro gamma interferon treatment), while the H-2D class I gene was normally transcribed. Another defective transcription was also observed for a gene in the Tla region (gene 37). This low '37' phenotype was corrected by in vitro treatment of the M4 cell line with gamma interferon, which indicates that this class I gene of the Qa/Tla region has an interferon response sequence in the promoter.

Abstract
Various investigators have examined the relationship between tumor cell susceptibility to natural killer (NK) cell lysis and the expression of HLA class I antigens on the tumor cell. There is controversy as to whether or not an inverse relationship exists, and if so, the basis of the relationship between these two phenomena remains undefined. To address these questions, the genomic clones for two HLA antigens were transfected into the erythroleukemia cell line K562, a cell line that is used as the standard to assess human NK and major histocompatibility complex (MHC) nonrestricted cytolysis. Susceptibility to NK lysis was not affected by the de novo expression of HLA antigens on the K562 after DNA mediated gene transfer. Interferon-gamma (IFN-gamma) treatment of K562 induced levels of MHC class I antigen surface expression comparable to those found on the transfected cells; however, the IFN-gamma-treated cells were resistant to NK lysis. When very high levels of surface HLA antigens were induced on the transfectants, a potential effect of class I MHC expression on K562 lysis could be discerned that was distinct from the resistance to NK lysis induced by IFN-gamma-treatment.

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.

Our present data show that clones which express low amounts of H-2 class-I antigens are poorly metastatic in a post-surgical spontaneous metastasis assay, while those expressing high levels of class-I antigens possess a high metastatic capacity. These results correlate inversely with local growth patterns of the clones. High metastatic capacity was associated with resistance to NK cells. In an experimental metastasis assay, based on intravenous administration of in vitro carried GR9 clones to syngeneic BALB/c mice, an opposite result to the post-surgical assay was obtained. Gamma-IFN treatment of B9 clones (H-2-deficient) enhanced H-2 class-I expression and diminished experimentally induced metastases. Metastatic colonies, from the spontaneous metastasis assay, obtained from different organs, showed changes in the ratio H-2K/H-2D. There was a tendency for down-regulation of the expression of H-2K molecules in H-2-positive clones and for up-regulation of H-2D expression in H-2-negative clones.

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
Major histocompatibility complex class I transcriptional products and cell surface expression of their corresponding proteins were measured in tumorigenic Lewis lung carcinoma cells with either high metastatic activity (G4 cells) or with no metastatic activity (G2 cells). The transcriptional products were measured by hybridization to gene-specific oligonucleotide probes for H-2Kb and H-2Db respectively. The cell surface density of the corresponding H-2 glycoproteins was determined by FACS cell sorter analysis and by radioimmunoassay using anti-H-2Kb and anti-H-2Db specific monoclonal antibodies. The analyses revealed that the cell surface density of both Kb and Db was reduced 4-9 fold in G4 cells compared to G2 cells. However, this reduction of G4 cell surface expression of MHC class I molecules was not reflected at the mRNA level since both subclones had similar low levels of detectable Kb and Db specific mRNA. beta 2-microglobulin was analysed at the mRNA and protein level and found not to be the rate-limiting factor in the MHC class I expression of the metastatic G4 cells. Thus, the cell surface expression of H-2Kb and H-2Db by the two Lewis lung carcinoma subclones did not correlate with the amount of specific mRNA. Other regulatory mechanisms of gene expression acting at the levels between transcription and the appearance of the gene product at the cell surface must therefore account for the observed difference in the cell surface expression of MHC class I molecules of the two Lewis lung carcinoma cells. The potential importance of MHC class I expression in the metastatic capacity of the tumor cells is discussed.

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
Tumorigenicity in immunocompetent syngeneic mice and H-2 class I antigen expression of BPV1-transformed mouse cell lines had no correlation. H-2 expression was examined using monoclonal anti-(H-2Kb) and anti-(H-2Db) antibodies in immunofluorescence staining for flow cytometry analysis and by determining the sensitivity of the cells to cytolysis by allostimulated spleen cells. Nontumorigenic cell lines were as resistant as tumorigenic cell lines to natural killer activity. The results indicate that in our model defence by natural killer cells is not a decisive factor. The results also show that instead of or in addition to H-2 class I antigens other factors (e.g. the presence or absence of virus-specific antigens) are important in determining the tumorigenicity of BPV1-transformed cell lines.

Abstract
Interferon-gamma (IFN-gamma) treatment or in vivo passage of the murine YAC-1 lymphoma resulted in reduced sensitivity to in vitro lysis by syngeneic murine spleen cells cultured in rIL-2 (LAK-cells). IFN-gamma treatment also rendered the murine B16 melanoma less sensitive to lysis by syngeneic LAK cells, whereas in vivo passage did not alter LAK sensitivity. The reduction in sensitivity to lysis correlated with enhanced expression of cell surface H-2 on the target cells. The possible role of H-2 was studied with a beta 2-microglobulin-deficient, and thus H-2-deficient, variant of the YAC-1 lymphoma. This variant line remained H-2 negative even after IFN-gamma treatment or in vivo passage, and was highly sensitive to LAK-cell-mediated lysis, even after IFN-gamma treatment or in vivo passage. The present results are discussed in relation to IFN-gamma and in vivo induced modulation of MHC class-1 molecules on target cells and the possible consequences for interaction with activated as well as "natural" effector cells.

Abstract
The c-myc oncogene downregulates class I HLA expression in human melanoma. The major class I HLA antigens are encoded by three loci, A, B, and C, and we investigated whether these loci are suppressed equally by c-myc. In three melanoma cell lines with high c-myc expression, we analyzed mRNA, protein, and cell surface expression of the class I HLA antigens. Whereas the HLA-B locus expression was found to be strongly reduced, the HLA-A locus was expressed normally. Analysis of c-myc-transfected clones of two melanoma cell lines confirmed that c-myc preferentially suppresses the class I HLA-B locus. Immunohistochemical analysis of fresh melanoma lesions also showed that in the tumors the HLA-A loci are expressed normally, while on the majority of tumor cells no HLA-B antigen expression was found. This downregulation may have consequences for the recognition of malignant cells by tumor-infiltrating lymphocytes. Our results predict that HLA-B-restricted cytotoxic T cells will be unable to kill high c-myc-expressing melanoma cells.

Abstract
We have used the 3-Methylcholanthrene induced T-10 fibrosarcoma tumour cell system (H-2b xH-2k)F1 to elucidate the possible correlation between metastatic potential, expression of individual H-2 antigens and susceptibility to NK cells. Transfection of the non-metastatic and NK sensitive IC9 cells (Db+, Dk-, Kb-, Kk-) with the H-2Dk gene, altered the metastatic phenotype of the parental cells, yet had no effect on the susceptibility of these tumour cells to lysis by NK and did not elicit a specific CTL response in syngeneic hosts. Variants of the metastatic and NK resistant IE7 clone (Db+, Dk+, Kb-, Kk-), lacking H-2Dk, were selected by treatment with monoclonal anti H-2Dk antibodies and complement. These variants were sensitive to NK and poorly or non metastatic. Retransfection of 'Dk' 'loss' variants with the H-2Dk gene, resulted in the isolation of several clones expressing a wide range of metastatic phenotypes but maintained sensitivity to NK. These results indicate that the H-2D region of the MHC and or closely linked genes may be involved in the complex interrelationship between target susceptibility to NK and metastasis.

Abstract
The relationship between MHC class I (H-2) expression and tumorigenicity was investigated after intracerebral inoculation of the murine lymphoma YAC-1 and its H-2 negative variant, A.H-2-. YAC-1 was less tumorigenic than A.H-2- in normal as well as NK-depleted syngeneic A/Sn mice. However, in T-cell-depleted syngeneic mice YAC-1 was as tumorigenic as A.H-2-. Following intracerebral growth, the H-2 expression of YAC-1 was markedly enhanced in a similar fashion as after intraperitoneal passage. The A.H-2- variant remained H-2 negative after intracranial passage. The H-2 negative variant cells were not rejected from the brain even when intermixed with wild-type YAC-1 cells prior to intracerebral inoculation, excluding an "innocent bystander" effect. In vitro, the intracerebrally passaged YAC-1 line showed enhanced sensitivity to lysis by H-2 Kk Dd (H-2a) specific CTLs but decreased sensitivity to NK cells. The A.H-2- line was unchanged. Our data suggest that the lack of H-2 molecules may facilitate the growth of antigenic tumor cells in the brain due to escape from T-cell-mediated immunosurveillance. Our data also suggest, in line with other recent findings, that intracerebrally growing tumor cells are sheltered from NK cell-mediated rejection.

Abstract
The human breast cell line HBL100 acquires the capacity to invade normal tissues and to replace them by proliferation in vitro only at high passage levels (HPL). These cells therefore are a useful model for studying tumor progression in vitro. We have analyzed the expression of cell-surface markers supposed to be involved in the control of the neoplastic process. Quantitative flow cytometry has revealed that: (1) spontaneous expression of HLA class-I antigens strongly decreases in HPL HBL100 cells vs. LPL cells, which parallels amplification and over-expression of c-myc oncogene; (2) HLA DR antigens can be induced by IFN-gamma in LPL but not in HPL HBL100 cells; (3) HBL100 cells secrete a soluble protein factor which specifically inhibits HLA DR induction by IFN-gamma even in heterologous cell systems; (4) 50% of LPL HBL100 cells express integrin beta 3, whereas HPL HBL100 cells lose this antigen; (5) this cell line is myoepithelial in origin, since 100% of HBL100 cells exhibit the CD10 antigen. Our data stress a role of HLA antigens, of some integrins and of c-myc in the acquisition of malignant potential by myoepithelial mammary cells of the HBL100 line.

Abstract
BSp6S and BSp73AS are two rat tumors which grow locally after intra-footpad (ifp) application. BSp73ASML and BSp6AS are variants, which metastasize via the lymphatics. Both variants have lost adherence properties, as shown by in vitro culture on plastic surfaces, suggesting that loss of adherence may be accompanied by increased metastasizing capacity. However, after growth of BSp6S and BSp73AS in vitro on poly(2-hydroxyethylmethacrylate) (polyHEMA)-coated plates, which resulted in loss of adherence and spreading, and subsequent intravenous (iv) or ifp injection of non-adherent tumor cells into syngeneic rats, metastasizing capacity was not increased. It is concluded that loss of adherence may facilitate metastatic spread, but certainly is not sufficient for initiation.

Abstract
We have established low- and high-metastatic clones, named RCT(-) and RCT(+) cells, respectively, from the RCT (Radiological, Chiba, and Toyama) sarcoma spontaneously developed in a C3H/He male mouse by the limiting-dilution method in vitro or by the combination of the lung passages and limiting-dilution methods. After 20 serial passages in vitro, the metastatic potential of each clone did not alter. Morphologically, both cells were spindle-shaped, but RCT(+) cells were slightly thicker and larger than RCT(-) cells. The organization of actin-containing filaments was slightly poorer in RCT(+) cells than that in RCT(-) cells. Marked differences were observed in their growth characteristics and adhesiveness to plastic or collagen-coated surfaces, that is, RCT(+) cells grew more slowly but could adhere more rapidly and firmly to the surfaces than RCT(-) cells. RCT(+) cells were agglutinated by all lectins used but several lectins could not agglutinate RCT(-) cells. These results could be a reflection of the difference in oligosaccharide residues on the surface of each cell and, in part, might reflect the difference in organization of the actin-containing filaments that regulate the mobility of lectin receptors. No significant difference between these cell clones was noted in their sensitivity to natural-killer-cell-mediated cytotoxicity in vitro. RCT(-) and RCT(+) cells are considered to be the most useful experimental model for the study of the certain sarcomas.

Abstract
We have examined the metastatic behaviour of cells from a series of clones of RIF-1 fibrosarcoma, a recently derived murine tumour. The clones were grown to different sizes (small: 10(5)-10(6) cells and large approximately 2 x 10(7) cells) and their metastatic potential was quantified using an experimental metastasis assay. There was significant variability between the metastatic potential of clones derived from the same population. Furthermore large clones had higher metastatic efficiency (metastases/cell injected) than the small clones derived from the same population. The results from these experiments indicate that metastatic variants are generated during the growth of the clones. The mean effective rate of generation of metastatic variants was estimated using Luria-Delbruck fluctuation analysis to be 1.7 x 10(-5)/cell/generation. The data described are consistent with a dynamic heterogeneity model of metastasis, in which the variant phenotypes are postulated to arise in growing tumour cell populations at a high rate but need not be stable in order to produce metastases. The results thus indicate that the model is applicable to a recently derived tumour as well as the extensively transplanted KHT sarcoma, B16 melanoma and OTF9 embryonal cell carcinoma.

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
We analyzed mechanisms responsible for organ-specific metastasis by using two melanoma sublines derived from the same mouse tumor, of which one colonizes the lungs (F10) and the other colonizes the liver (L8) after intravenous injection. Both lines were obtained by selective growth in lung or liver after injection of tumor cells into a tail vein or portal vein. Contrary to common concepts, the cells of the liver-colonizing melanoma line do not accumulate preferentially in the liver after intravenous administration in vivo. However, the selective survival and proliferation of these melanoma cells in the target organ (liver) may be explained by the unexpected observation that they can be specifically stimulated to proliferate in the presence of hepatocytes, whereas the cells of the lung-colonizing line cannot. Growth promotion under coculture conditions in vitro was monitored both by thymidine incorporation into DNA and by increase in cell numbers. The proliferative stimulus is not mediated by an easily diffusible factor but rather depends upon direct contact between liver cells and those tumor cells that metastasize to that particular organ.

Abstract
Murine RCT(+) sarcoma cells were sorted using a fluorescence-activated cell sorter with regard to the expression of H-2 antigens and then an increased H-2-expressing subclone was established, and named RCT(+)H-2+. The experimental metastasis of RCT(+) cells was compared with that of RCT(+)H-2+ cells by counting pulmonary colonies on the 21st day after i.v. inoculation of tumor cells (5-10 x 10(4)/mouse). When mice were inoculated with RCT(+) cells, mean numbers of pulmonary colonies were 2.1(range 0-6), 2.8(range 0-7) using 5 x 10(4) and 1 x 10(5) cells, respectively. On the other hand, in the mice inoculated with RCT(+)H-2+ cells, figures obtained were 7.0(range 4-16), 31.9(range 13-79), using 5 x 10(4) and 1 x 10(5) cells, respectively. The survival rate of RCT(+)H-2+ cells was higher than that of RCT(+) cells, when this was assayed in the early stage after i.v. injection of 51Cr-labeled cells (1 x 10(5) cells/mouse). In addition, RCT(+)H-2+ cells were more resistant than RCT(+) cells to lysis mediated by natural killer cells. These data suggest that an increase in metastatic ability was paralleled by an increase in the H-2 antigen expression and a decrease in sensitivity to the natural killer cells.

Abstract
We investigated whether the adoptive transfer of H-2-incompatible lymphokine-activated killer (LAK) cells would efficiently demonstrate antitumor activity without damaging the normal host cells. Allogeneic LAK cells (5 X 10(7] did not cause graft-versus-host disease (GVHD) in irradiated recipients, whereas more than half of the mice transferred with the same dose of fresh allogeneic spleen cells developed GVHD. Repeated transfer (three times at 4-day intervals, 1.2 X 10(8) cells/mouse) did not result in GVHD. Graft-versus-host reaction (GVHR), which is detectable by spleen enlargement of recipients transferred with allogeneic lymphoid cells was also absent in LAK cell-transferred mice of all strain combinations tested. Host immune responses were not affected in these mice. Therefore, it is feasible to transfer allogeneic LAK cells. With the antitumor efficacy of allogeneic LAK cells, they preferentially lysed allogeneic tumor targets. Adoptive transfer of the allogeneic LAK cells led to a significant decrease in the lung-colonizing foci of intravenously inoculated B16 melanoma cells. Allogeneic LAK cells and syngeneic ones were equally active, in vivo. The use of allogeneic LAK cells may prove to be a valuable method for effective clinical antitumor immunotherapy.

Abstract
Treatment of tumor cells with interferon-gamma (IFN) frequently reduces their susceptibility towards NK cells and results in augmented expression of MHC antigens, which may increase immunogenicity of tumor cells. Depending on the relative strength of these opposing effects, i.e. escape from non-adaptive immune defense versus facilitated activation of T-cell-mediated defense, IFN-treatment may be beneficial or disadvantageous for the tumor-bearing host. This is demonstrated for the variants F1 and F10 of the B16 melanoma, which differ in metastasizing capacity. IFN-treatment of B16-F1 melanoma cells significantly reduced susceptibility towards non-adaptive immune defense, and increased metastasizing potential. On the other hand, H2K antigen expression was augmented by a factor of 50; concomitantly, lysability by CTL was increased, together with the number and expansion rate of cytotoxic T-cell precursors (CTLp) recruited after immunization with IFN-treated B16-F1. The benefit of increased antigenicity and immunogenicity outweighed the disadvantage or reduced susceptibility towards non-adaptive immune defense. B16-F10 cells were less susceptible to NK cells, expression of MHC antigens was found to be stronger and they were more immunogenic than B16-F1 cells. After IFN-treatment, susceptibility to non-adaptive immune defense was further reduced. Expression of MHC antigens as well as antigenicity and immunogenicity were only moderately augmented. As a consequence, the decreased susceptibility to non-adaptive immune defense was dominating in the tumor bearing host and could not be counterbalanced by immunization with IFN-treated B16-F10 cells. We interpret these data to show that a precise knowledge of the relative decrease in susceptibility to non-adaptive immune defense, the relative increase in MHC antigen expression, antigenicity and immunogenicity may allow a more precise prognosis of the influence of IFN on metastatic capacity in the B16 system, and eventually also in a clinical therapeutic regimen.

Abstract
Expression of class I HLA antigen has been shown to be reduced in a number of human tumours. Here we show that in a panel of 11 melanoma cell lines with variable class I HLA expression an inverse correlation exists between the mRNA levels of c-myc and class I HLA. This suggests that high expression of the c-myc oncogene might inhibit the class I HLA expression. To test this hypothesis a melanoma cell line with a low c-myc and high class I HLA mRNA expression was transfected with a c-myc expression vector. All clones expressing the transfected c-myc gene show reduced class I HLA mRNA and beta 2-microglobulin mRNA expression. Reduced class I HLA mRNA levels result in a lowered class I protein expression on the cell surface. Treatment with gamma-interferon fully restores the class I HLA and beta 2-microglobulin expression in these cells. This effect is preceded by a transient decrease of the c-myc mRNA level. These results show that the class I HLA expression is modulated by the level of c-myc expression, thus opening up the possibility that high expression of this oncogene influences the interaction of melanoma cells with the immune system.

Abstract
Primary colorectal carcinomas of an unselected group of 159 patients 126 of whom could be curatively resected were examined for the expression of MHC class I antigens with monoclonal antibody W6/32 directed against a non-polymorphic determinant of HLA-A,B,C heavy chain. One hundred and nine (68.6%) were found to express HLA-A,B,C antigens in normal quantities, 33 (20.8%) showed a substantial reduction in expression, while 17 (10%) lacked these antigens either completely or incompletely. The loss of HLA-A,B,C was inversely correlated with the degree of differentiation. The tendency of mucinous carcinomas to lack class I antigens was statistically not significant. Tumours with distant metastatic spread at the time of operation tended to be normal with respect to HLA-A,B,C expression. Within the curatively resected group, poor differentiation and mucus production were risk factors for survival as could be shown by life table analysis after a maximum follow-up of 39 months. In contrast, the mode of HLA-A,B,C expression of the primary tumour did not influence survival within this time of observation. We conclude that in spite of increasing experimental data suggesting the contrary, the presence or absence of MHC class I antigens does not seem to profoundly modify tumour biology, at least in human colorectal carcinoma.

Abstract
In this study, we have used the T-10 fibrosarcoma tumor cells to further analyze the relationship between metastatic competence, expression of H-2K antigens and susceptibility to lysis by virus augmented NK cells in vitro. Our results show an inverse correlation between metastatic properties of the original T-10 clones, IC9 and IE7, and susceptibility in vitro to lysis by virus-augmented NK cells. Restoration by transfection of expression of H-2K genes (H-2Kb or H-2Kk) led to the alteration of the metastatic phenotype of the tumors cells, yet had minor influence on the putative susceptibility of these clones to NK. These observations suggest that expression of MHC gene products, while affecting metastases, does not exclusively determine sensitivity to NK cells.

Abstract
The impact of interferon-gamma (IFN) treatment of tumor cells on non-adaptive and adaptive immune defense and its reflection by metastatic spread were evaluated using a weakly metastasizing variant of B16 melanoma (B16-FI). Treatment of B16-FI with IFN resulted in a decrease in binding structures for NK cells and concomitantly in augmented metastasizing capacity. In line with this, activation of NK cells and Mo, which led to reduction of metastatic nodes, was less efficient with IFN-treated B16-FI, while after elimination of non-adaptive immune defense, the number of metastases increased significantly, but irrespective of IFN treatment. On the other hand, IFN-treated B16-FI cells become more prone to killing by cytotoxic T-cells (CTL). This was due to increased lysability by CTL and to increased immunogenicity; i.e., a higher frequency of B16-specific CTL was observed after immunization with IFN-treated than with untreated B16-FI. The reverse phenomenon was observed with anomalous and/or lymphokine-activated killer cells (AK/LAK). The common cause of increased antigenicity and immunogenicity may reside in increased expression of class-I and de novo expression of class-II MHC antigens after IFN treatment. Increased antigenicity and immunogenicity of IFN-treated B16-FI was reflected by significant reduction of metastatic nodes, prolonged survival and increased TD100 in animals immunized with IFN-treated vs. untreated melanoma cells. Comparison of the divergent effects of IFN treatment on B16-FI melanoma cells showed that the benefit of increased antigenicity/immunogenicity clearly outweighed the disadvantage of reduced susceptibility to non-adaptive immune defense.

Abstract
The mechanisms of host H-2-associated resistance against metastasis of tumor cells were evaluated in relation to the H-2 phenotype of tumor cells. We used H-2 heterozygous H-2a/b and H-2d/b, and H-2 homozygous H-2b/b hosts, and H-2-associated variant lines of B16 cells (H-2b+, H-2b-). In H-2b/b hosts, H-2+ cells were highly metastatic in vivo, and were resistant to host NK effectors in vitro. Therefore, H-2a/b and H-2d/b hosts showed resistance to metastasis of H-2+ cells and their effectors showed killing activity to these cells in vitro. Though the host resistance was reduced by anti-asialo GM1 serum treatment, these hosts continued to demonstrate a considerable resistance against early survival and metastasis of the B16 cells. To evaluate this natural resistance, aside from the NK system, radiation bone marrow chimeras of F1-parental combinations were used. The data suggest that host MHC-associated resistance involves not only the NK defense system but also the host environmental resistance. Both exert resistance by recognizing the H-2 mismatch in relation to the host.

Abstract
In attempts to correlate metastatic potential with specific properties of tumor cells, homogeneous subpopulations, which are endowed with low or high metastatic potential, have been selected from Lewis lung carcinoma (3LL). In particular, since cell surface constituents are possibly involved in the metastatic process, changes in antigen expression have been correlated with the metastatic potential of 3LL variants. In this view, we quantitated the expression of MHC (Db,Kb) antigens and of a tumor specific protein (TSP) identified by the monoclonal antibody (MoAb) 135-13C on some "in vitro" and "in vivo" variants of 3LL. The MoAb 135-13C was found to recognize a TSP-180 protein that appears on the cell surface of several murine carcinomas, but is not detected on normal cells in culture. Studies of the MHC expression on these variants, by the use of the indirect immunofluorescent staining or the direct binding of the MoAb to H-2Db (28-14-8) and the MoAb to H-2Kb (28-13-3), demonstrate that "in vivo" and "in vitro" 3LL variants which, are endowed with a higher metastatic potential, express on the cell surface a higher amount of the Db antigen. By contrast, all the 3LL lines have few cells recognized by the MoAb to H-2Kb and express low amounts of this antigen on the cell surface. The direct binding to different tumor lines and the analysis of the immunoprecipitates from the cell lysates by the use of the MoAb 135-13C demonstrate that the TSP-180 protein is highly expressed on 3LL cells which possess high capacity to metastasize to the lung. The variations induced in 3LL metastatic phenotype by the injection of the variant lines in allogeneic mice (Balb/c, C3HeB:H-2d,H-2k, respectively) or after treatment with the specific MoAb 135-13C have, also, been studied. An attempt was made to correlate the changes in 3LL metastatic phenotype with the expression of the TSP-180 protein and of the MHC antigens. We conclude that a high expression on the cell surface of the Db antigen and of the TSP-180 protein, is associated with a high malignant phenotype of 3LL tumor cells.

Abstract
We have studied the influence of interferons (IFNs) on the metastatic potential of mouse colon adenocarcinoma, COLON 26, cells. Pre-treatment of the cells in vitro for 24 hr with recombinant murine IFN-gamma (rMuIFN-gamma) significantly increased the number of lung tumour nodules when cells were injected i.v. into immunocompetent BALB/c mice and BALB/c nude mice. However, when MuIFN-gamma-pre-treated cells were injected into beige (NK-deficient) nude mice or anti-asialoGM 1 (asGM 1)-serum-treated BALB/c mice (NK-depleted) no enhancement of metastatic potential was seen. Pre-treatment of COLON 26 cells with recombinant human IFN-alpha A/D (Bg1 I), an IFN with equal activity on human and mouse cells, did not significantly enhance their subsequent metastases in immunocompetent or immunodeficient mice. In fact, there was a small but significant decrease in the number of tumour nodules in the lungs of beige nude and asGM 1-treated mice. The effects of rMuIFN-gamma on COLON 26 cells did not appear to be related to an alteration in MHC expression. COLON 26 cells constitutively express H-2D and H-2K antigens and both IFNs had equal enhancing (approx. 2-fold) activity on the expression of these antigens at the doses used in this experiment (10(3)U/ml). We conclude that pre-treatment with rMuIFN-gamma renders COLON 26 cells resistant to in vivo NK-cell lysis via a mechanism that does not involve changes in MHC expression.

Abstract
Pre-treatment of B16 melanoma cells with recombinant interferon-gamma (IFN-gamma) markedly increased their lung-colonising capacity following i.v. injection into syngeneic mice as compared with control cells. A similar enhancement was observed following the injection of treated cells into athymic nude mice but not in athymic mice carrying the beige mutation. Pre-treatment of syngeneic mice with anti-asialo GM1 antibody effectively abrogated any interferon-induced increase in experimental metastatic activity. The same IFN-gamma treatment significantly increased resistance of B16 cells to splenic natural killer (NK) cell activity as determined by in vitro assays. IFN-alpha/beta pre-treatment of B16 cells decreased sensitivity to NK-cell-mediated lysis to a lesser extent than IFN-gamma and had no detectable effect upon the subsequent metastatic activity of the tumor cells. Class-I antigen expression was altered by these IFN treatments, with IFN-gamma causing dramatic increases in expression of H-2Db antigen, in a pattern consistent with the possibility that increased H-2 antigen expression on B16 cells led to decreased NK-cell sensitivity which was reflected by an increase in experimental metastatic capacity.

Abstract
The relationship between major histocompatibility complex (MHC) antigens and metastasis was investigated on B16 melanoma variants. B16 cell lines express low amounts of murine MHC (H-2) antigens. A high expression can be induced in line B16-A by in vitro treatment with immune interferon (IFN-gamma) or by in vivo transplant in allogeneic mice. The increase of H-2 antigens correlated with an enhancement of lung colonization in young syngeneic mice. The higher metastatic capacity of B16-A cells with induced high levels of H-2 antigens was observed also in adult mice and in young mice pretreated with cyclophosphamide. These results were confirmed investigating the behaviour of a mutant B16 clone (B78H1) which was selectively resistant to the H-2-inducing action of IFN-gamma: lung colonization ability was not increased by IFN pretreatment. The study of variants derived from individual B16-A lung colonies revealed a wide range of H-2 levels. Variants with a low expression had a low colonization ability; one out of two variants with a high H-2 expression also was poorly colonizing. IFN-gamma-mediated H-2 expression appeared to act as an enhancer, rather than a determinant of B16 metastatic capacity.

Abstract
Two tumor lines derived from 3LL (Lewis lung carcinoma) endowed with different metastatic potential and stable for their metastatic phenotype during serial in vivo passages, have been analysed for growth and dissemination following treatment with a monoclonal antibody. We have used a recently developed MoAb 135-13C to a tumor-associated antigen of murine lung carcinoma having an apparent molecular weight of 180,000 (TSP-180). The metastatic dissemination of the 3LL variants before and after treatment with the MoAb has been correlated with the expression on the cell surface of the MHC antigens (Db, Kb) and of the TSP-180 protein. The results of this study indicate that cell with high TSP-180 protein expression and MHC antigen expression have the greatest metastatic potential. Administration of MoAb 135-13C to tumor-bearing mice or i.v. injection of cells preincubated with the MoAb 135-13C increase the dissemination capacity of the variant endowed with lower metastatic potential while inducing a reverse effect on the high metastatic one. Studies on the MHC expression demonstrate that MoAb 135-13C treatment induces changes in the Db and Kb expression at level of secondary neoplasms. The results are discussed in view of the importance of the use of the metastatic variants to study therapeutic effect of specific targeting agent.

Abstract
We investigated the manner in which rIL-2 induced effectors in vitro (LAK cells), which, like NK cells, lyse targets nonspecifically and discriminate nonself, and how H-2 as the self-marker affects the LAK cell killing mechanism. NK cells showed an appreciably higher killing activity to B16 melanoma H-2- cells than to H-2+ cells. In contrast, LAK cells lysed more efficiently to H-2+ cells. The in vivo experiments showed that the NK cells prevented pulmonary metastasis of B16 H-2- cells in the normal syngeneic host, whereas the transferred LAK cells had a preferential inhibitory effect on the pulmonary metastasis of B16 H-2+ cells in the immunodeficient syngeneic hosts. Taken together, these results show that the H-2-encoded or H-2-associated molecules contribute to the triggering signal in the lysis by LAK cells, whereas the NK cells recognize the reduced self H-2 expression on the targets, thereby contributing to a trigger of the lysis.

Abstract
Treatment of H-2-deficient nonmetastatic B16 melanoma cells with physiological doses of interferon gamma (IFN-gamma) reduced cellular growth in vitro but induced a shift to the lung-colonizing phenotype as assessed after intravenous injection of the treated cells. As little as 1 antiviral unit of recombinant IFN-gamma per ml induced B16 cells to form 3-40 pulmonary metastases in each injected mouse, whereas a 1000-fold higher concentration of IFN-beta was required to see similar effects. IFN-gamma may induce cell-surface molecules that contribute to the metastatic ability of the tumor cells. The efficient enhancement of metastatic ability after IFN-gamma treatment of the B16 cells was paralleled by an increased H-2 antigen expression and decreased sensitivity to natural killer cells. The experiments support the idea that metastasis may not depend exclusively on stable genetic changes or heterogeneity within a tumor population but may be also influenced through the modulation of the phenotype by physiological or pharmacological agents. The results are also discussed with regard to the role of different effector cells in tumor cell clearance and in relation to lymphokine-based strategies for therapy.

Abstract
The RBL-5 lymphoma has previously been shown to be highly sensitive to natural hybrid resistance, under the control of H-2 genes at the host level. The present study of the RBL-5 tumour was focused on progression towards disseminated growth after intravenous (i.v.) inoculation in the syngeneic host and the possible influence of the MHC genes at the tumour cell level. Data are presented to illustrate that there is no obligatory association between reduced H-2 expression and increased malignancy, and that the opposite may be observed. The wild type RBL-5 line expressed readily detectable H-2K and H-2D products, and a highly malignant subline selected for lung colonization in vivo did not show any reduction but rather enhanced expression of these antigens. Depending on the inoculum size, this selected subline caused disseminated lymphoma (in the liver, spleen and lungs) at a faster rate or higher frequency of animals than the wild type line. Conversely, a subline selected for reduced H-2 expression in vitro, by repeated treatments with antibody and complement, failed to form colonies in any organ after i.v. inoculation, even if the cell dose was increased by more than 100-fold in comparison with the threshold dose for the wild type line. This H-2-deficient subline was completely resistant to syngeneic RBL-5 immune cytotoxic T lymphocytes (CTL). Clones isolated during selection of the subline showed different degrees of reduction in sensitivity to H-2 specific CTL, but an inverse pattern of sensitivity to poly I:C induced natural killer (NK) cells. Selection pressure imposed by NK-mediated elimination directed preferentially against cells with reduced H-2 expression may be one explanation of why the gain of histocompatibility antigens is associated with tumour progression in some systems. Another important implication taken up for discussion is that tests for the effect of MHC modulation on tumour growth or immunotherapy require careful experimental design, to cover the action of different effector mechanisms in vivo.
