Abstract
Her-2/neu (HER-2) is a 185-kDa receptor-like glycoprotein that is overexpressed by a variety of tumors such as breast, ovarian, gastric, and colorectal carcinomas. Overexpression of this oncogene is directly associated with malignant transformation of epithelial cells. The frequency of HER-2 overexpression varies among the different types of cancers, but universally represents a marker of poor prognosis. The critical role of HER-2 in epithelial oncogenesis as well as its selective overexpression on malignant tissues makes it an ideal target for immunotherapy. Antibodies and T cells reactive to HER-2 are known to naturally occur in patients with HER-2 positive tumors, confirming the immunogenicity of the molecule. Both antibodies as well as T cells reactive to HER-2 have been utilized for immunotherapy of HER-2 positive tumors. The "humanized" monoclonal antibody Herceptin has been tested in several clinical trials and found to be an effective adjuvant therapy for HER-2 positive breast and ovarian cancer patients. However, the frequency of patients responding to Herceptin is limited and a majority of patients initially responding to Herceptin develop resistance within a year of treatment. The use of vaccination strategies that generate T cell responses with or without accompanying antibody responses may serve to mitigate the problem. Various strategies for generating T cell-mediated responses against HER-2 are currently being examined in animal models or in clinical trials. The potential advantages of the various approaches to immunotherapy, their pitfalls, and the mechanisms by which HER-2 positive tumors can evade immune responses are discussed in this review.

Abstract
We have analyzed 30 human tumor specimens (two breast, six lung, and 21 ovarian carcinomas and one malignant melanoma) for the expression of the transporter associated with antigen processing, TAP-1. Cell suspensions judged to contain negligible contamination with non-tumor cells were tested for reactivity with the antibody directed to TAP-1 in Western blot. According to these results all lysates prepared from the tumor samples contained the protein, but with considerable quantitative variations. Tumors exposed in vitro for a short time to IFN-gamma and TNF-alpha had elevated TAP-1 levels in 12 out of 30 experiments. In accordance with previous results, the tumor cell populations were heterogeneous with regard to MHC class I expression, as analyzed by indirect immunofluorescence on viable cell suspensions. Short term in vitro treatment with IFN-gamma and TNF-alpha elevated MHC class I expression in several tumors. In several mixed cultures, cytokine treated tumor cells induced cytotoxic activity in autologous or allogeneic lymphocyte populations. In vitro treatment with IFN-gamma and TNF-alpha upregulated thus the expression of MHC class I and TAP-1 in a fraction of the tumor samples. However the potentiation of the capacity to interact with T cells induced by the cytokines was not always parallel with the changes in these two parameters. It is therefore likely that the cytokine treatment induced additional changes in the tumors which contributed to their capacity to elicit the T cell response.

Abstract
In a group of four human tumor cell lines comprising one melanoma, one glioma, one teratocarcinoma and one neuroblastoma, the expression of the intercellular adhesion molecule-1 (ICAM-1) was found to be significantly increased following treatment with 10 microM of all-trans retinoic acid. In the melanoma and glioma cell lines HS 294T and HS 683, greater than 90% of the cells reacted with the anti-ICAM-1 monoclonal antibody (mAb) CL203.4 in the absence of treatment. Retinoic acid increased the cell surface expression of the molecule by 2-fold. In the teratocarcinoma and neuroblastoma cell lines, TERA-2 and SK-N-SH, the constitutive expression of ICAM-1 was weak, the percentage of cells stained above the background being less than 25%. Retinoic acid induced ICAM-1 expression in greater than 80% of the cells and increased the levels of expression by 2.5 to 3-fold. Immunoprecipitation studies in biosynthetically labeled cells as well as RNase protection analysis confirmed that retinoic acid treatment increased the amount of ICAM-1 at both the protein and mRNA level. The induction or stimulation occurred within 24 h, was maximal after 4 days and reversible.

Abstract
MHC class I antigens on tumor cells are expected to play an important role because they regulate the sensitivity to antitumoral immunological mechanisms. Overall or selective qualitative or quantitative changes in MHC molecules may modify the recognition of tumor cells by components of the immune system. It seems clear that MHC antigen expression on tumor cells is important in triggering the immune response by autologous lymphocytes. A deficiency in or lack of MHC class I antigens may have profound effects on T and NK cell activity. In experimental models, variation in the expression of MHC class I antigens has been shown to exert a decisive influence on local tumor growth and metastasis. However, there is little information about the influence of selective loss of individual locus products on the behavior of human tumor cells. Total and selective HLA losses have been found in a large variety of tumors, and different mechanisms have been shown to be responsible for these changes. In some examples, HLA losses are associated with a poor degree of tissue differentiation and poor prognosis. In other tumors, however, no such association has been found. We do not know whether HLA class II expression in neoplastic cells plays an immunological role, although, with the exception of melanoma, HLA class II expression is more frequently observed in tumors with a more favorable prognosis. Finally, there is no doubt that we need to learn more about how to manipulate the expression of MHC class I and II antigens in human tumors, in order to stimulate immune response.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
By one-dimension isoelectric focusing we analysed the major histocompatibility complex class I antigen expression on human tumours. Blood lymphocytes of the patients, processed in parallel, served as a basis for comparison. The prerequisite for the analysis is the preparation of metabolically active tumour cell suspensions devoid of significant leucocyte contamination. The method was found to be suitable for study of the expression of HLA alleles on ex vivo tumour cells and allowed the detection of changes imposed by in vitro treatment with interferon gamma and tumour necrosis factor alpha.

Abstract
Peripheral blood lymphocytes were cultured for 5 days with allogeneic tumor cells (allogeneic mixed lymphocyte/tumor cell culture), and subsequently cultured with recombinant interleukin-2 for 12 days. These cultured cells were found to be cytotoxic to autologous tumor cells. Results of two-color analysis using monoclonal antibodies to cell markers showed that more than 80% of their cultured cells were CD3+ cells, and CD4+ cells showed a higher distribution than CD8+ cells. However, CD8+ cells had a much higher killing activity with autologous tumor than did CD4+ cells, when estimated by an elimination study using monoclonal antibodies to T cell phenotypes and complement. The "cold-target" inhibition test showed that the cytotoxicity of these cells for autologous tumor cells was inhibited by unlabeled autologous tumor cells but not by unlabeled stimulator cells. Furthermore, about 40% of the cytotoxicity was suppressed by blocking of HLA class I antigen with a monoclonal antibody on autologous tumor cells. Thus, cytotoxic activity of lymphocytes to autologous tumor restricted by target cell HLA class I antigen is possibly induced by allogeneic tumor-stimulation.

Frequency of abnormal expression of HLA-A,B,C and HLA-DR molecules, invariant chain, and LFA-3 (CD58) in colorectal carcinoma and its impact on tumor recurrence. INTERNATIONAL JOURNAL OF CANCER.

Abstract
HLA-A,B,C and HLA-DR molecules are involved in cognate LFA-3 (CD58) in antigen-independent T-cell/target-cell interaction. T-cell-mediated host-versus-tumor response might therefore depend on the presence of both types of molecules on the surface of the target cell. To investigate whether presence or absence of these molecules in colorectal carcinoma influences the recurrence rate, 149 patients who underwent curative surgery were surveyed for a maximum of 65 months (mean, 48 months). As determined by immunohistochemistry, aberrant reduction of HLA-A,B,C determinants was observed in 34.9 and a complete loss in 8.7% of the tumor specimens. An induction of HLA-DR molecules was found in 55.0 and of the HLA-DR-associated invariant chain (Ii) in 81.9%. An abnormal reduction of LFA-3 was detected in 43.6%, while a complete loss of this structure was observed in 6.7%. Reduction/loss of HLA-A,B,C was correlated with reduction/loss of LFA-3 (p = 0.03). In contrast to the prognostic role of tumor stage and grade, the presence vs. absence of all these structures was not correlated with the recurrence rate. We conclude that, although encoded on different chromosomes, an abnormal reduction/loss of HLA-A,B,C and LFA-3 might be the consequence of one transacting down-regulating signal. However, the resulting deviant immunophenotypes do not profoundly influence survival and growth potential of residual tumor cells.

Abstract
To evaluate the impact of MHC antigen expression on the survival of patients with cancer, 77 human breast carcinomas were investigated for the expression of beta 2-microglobulin (beta 2m), HLA-A,B,C and HLA-DR. Thirty-one benign breast tumours were stained for comparison. The results for the carcinomas were related to the survival data of the cancer patients. The expression of beta 2m, HLA-A,B,C and HLA-DR was significantly lower in malignant tumours compared to the benign lesions. Whereas all benign tumours were positive for beta 2m and HLA-A,B,C and 28/31 positive for HLA-DR the following positivity rates were found in carcinomas: 74/77 for beta 2m, 57/77 for HLA-A,B,C and 10/77 for HLA-DR. The follow-up (median 45 months) of 66 cancer patients for overall survival and of 65 patients for disease-free survival revealed no influence of beta 2m, HLA-A,B,C or HLA-DR expression on the prognosis of this cancer. In conclusion, experimental data indicating the importance of MHC antigens in anti-tumour responses are not confirmed by the analysis of cancer patient survival data.

Expression of the adhesion molecule ICAM-1 and major histocompatibility complex class I antigens on human tumor cells is required for their interaction with autologous lymphocytes in vitro.

Abstract
In a group of 30 human tumors, comprising 12 lung, 14 ovarian, 2 breast carcinomas, 1 hypernephroma and 1 mid-gut carcinoid, the expression of major histocompatibility complex (MHC) class I molecules and the intercellular adhesion molecule 1 (CAM-1, CD54) was found to vary independently. Some tumors expressed both or neither of these molecules. Among 9/13 ICAM-1+ tumors, in which greater than 50% cells reacted with the anti-ICAM-1 monoclonal antibody (mAb) (LB-2), the class I antigen was also detected on greater than 50% of the cells. Only 2 ICAM-1+ tumors were class-I-. In 5/17 cases the tumors were MHC-class-I+ and ICAM-1-. Lymphocytes collected from the blood or from the tumor site were assayed for recognition on the tumor cells in the auto-tumor cytotoxicity test and in mixed lymphocyte tumor cell culture (MLTC). Positive results were obtained only with the MHC-class-I+/ICAM-1+ tumors. In vitro treatment of the tumor cell suspensions with interferon gamma and tumor necrosis factor alpha (TNF alpha) induced or enhanced the ICAM-1 and/or class I antigen expression in 8/12 cases. Of the tumor samples treatged, 8/9 acquired stimulatory capacity and 3/10 became susceptible to lysis by the lymphocytes. In 6/6 MLTC performed with the cytokine-treated tumor cells, cytotoxicity against the autologous tumor was generated. Three of these MLTC lymphocytes also lysed the untreated targets. mAb directed to class I antigens or to ICAM-1 inhibited both the stimulation by and the lysis of tumor cells when confronted with fresh lymphocytes. The cytotoxicity generated in the MLTC was also inhibited. If, however, the cytotoxic function was induced in MTLC containing interleukin-2 (5 U/ml), inhibition was obtained only by pretreatment of the targets with mAb against ICAM-1. The results show thus (a) that the lymphocytes react in vitro with tumor cells only if these express both MHC class I molecules and ICAM-1; (b) that expression of these molecules can be induced by interferon alpha and TNF alpha; (c) that cytotoxic effectors generated in the MLTC with cytokine-treated tumors can also act on the untreated tumor cells. The requirement of the two surface moieties for the interaction with lymphocytes was also substantiated by blockade with relevant mAb.
