Abstract
Two of the instruments onboard the OSIRIS-REx spacecraft, the MapCam color imager and the OVIRS visible and infrared spectrometer, observed the surface of asteroid (101955) Bennu in partially overlapping wavelengths. Significant scientific advances have been enabled by using data from these two instruments in tandem, but a robust statistical understanding of their relationship is needed for future analyses to cross-compare their data as accurately and sensitively as possible. Here we present a cross-instrument comparison of data acquired by MapCam and OVIRS, including methods and results for all global and site-specific observation campaigns in which both instruments were active. In our analysis, we consider both the absolute radiometric offset and the relative (normalized) variation between the two instruments; we find that both depend strongly on the photometric and instrumental conditions during the observation. The two instruments have a large absolute offset (>15%) due to their independent radiometric calibrations. However, they are very consistent (relative offset as low as 1%) when each instrument's response is normalized at a single wavelength, particularly at low phase angles where shadows on Bennu's rough surface are minimized. We recommend using the global datasets acquired at 12:30 pm local solar time for cross-comparisons; data acquired at higher phase angles have larger uncertainties.

Abstract
The composition of asteroids and their connection to meteorites provide insight into geologic processes that occurred in the early Solar System. We present spectra of the Nightingale crater region on near-Earth asteroid Bennu with a distinct infrared absorption around 3.4 micrometers. Corresponding images of boulders show centimeters-thick, roughly meter-long bright veins. We interpret the veins as being composed of carbonates, similar to those found in aqueously altered carbonaceous chondrite meteorites. If the veins on Bennu are carbonates, fluid flow and hydrothermal deposition on Bennu's parent body would have occurred on kilometer scales for thousands to millions of years. This suggests large-scale, open-system hydrothermal alteration of carbonaceous asteroids in the early Solar System.

Abstract
Cancer stem cell (CSC)-related therapy resistance has become a new obstacle to the successful application of cancer treatment and head and neck squamous cell carcinoma (HNSCC) is no exception to this finding. Head and neck squamous cell carcinoma is highly immune-suppressive, and recently the immune suppression and invasion of HNSCC-CSCs have been characterized. These characteristics have received research and clinical attention because they would enable the stratification of patients into specific cancer subtypes and, consequently, the establishment of new therapeutic approaches with improved efficacy. This review discusses the feasibility of CSC-targeted strategies and their incorporation with nanotechnology to improve the efficacy of cancer immunotherapy.

Abstract
This manuscript describes the functional properties of the exosomes released from melanoma cells. It details the characteristics of the tumor antigen chondroitin sulfate proteoglycan 4 (CSPG4), which is used as a marker to separate exosomes released by melanoma cells from exosomes released by nonmalignant cells. The results are discussed in view of the potential role of melanoma cell-derived exosomes in the escape of malignant cells from the host's immune system.

Abstract
Triple-negative breast cancer (TNBC) and malignant melanoma are highly aggressive cancers that widely express the cell surface chondroitin sulfate proteoglycan 4 (CSPG4/NG2). CSPG4 plays an important role in tumor cell growth and survival and promotes chemo- and radiotherapy resistance, suggesting that CSPG4 is an attractive target in cancer therapy. In the present work, we applied the drug delivery technology photochemical internalization (PCI) in combination with the novel CSPG4-targeting immunotoxin 225.28-saporin as an efficient and specific strategy to kill aggressive TNBC and amelanotic melanoma cells. Light-activation of the clinically relevant photosensitizer TPCS2a (fimaporfin) and 225.28-saporin was found to act in a synergistic manner, and was superior to both PCI of saporin and PCI-no-drug (TPCS2a + light only) in three TNBC cell lines (MDA-MB-231, MDA-MB-435 and SUM149) and two BRAFV600E mutated malignant melanoma cell lines (Melmet 1 and Melmet 5). The cytotoxic effect was highly dependent on the light dose and expression of CSPG4 since no enhanced cytotoxicity of PCI of 225.28-saporin compared to PCI of saporin was observed in the CSPG4-negative MCF-7 cells. The PCI of a smaller, and clinically relevant CSPG4-targeting toxin (scFvMEL-rGel) validated the CSPG4-targeting concept in vitro and induced a strong inhibition of tumor growth in the amelanotic melanoma xenograft A-375 model. In conclusion, the combination of the drug delivery technology PCI and CSPG4-targeting immunotoxins is an efficient, specific and light-controlled strategy for the elimination of aggressive cells of TNBC and malignant melanoma origin. This study lays the foundation for further preclinical evaluation of PCI in combination with CSPG4-targeting.

Abstract
A prospective study to evaluate the clinical usefulness of radioimmunodetection of melanoma in clinical practice is ongoing at the National Cancer Institute of Milan, Italy. Technical conditions for the application of the method were previously reported. In this trial, 99mTc-labelled F(ab’) 2 fragments of the 225.28S monoclonal antibody were used against a high molecular weight melanoma associated antigen (HMW-MAA). Retrospective studies on radioimmunodetection of melanoma have already been made by our group and by other Centers in about 300 patients. This study concerns the evaluation of the regional extension of primary melanoma. 23 patients with 32 suspected lymphatic involvements of melanoma on the trunk and arms underwent immunoscintigraphy. No false positive results were observed; 3 false negatives, one corresponding to a micrometastasis, were noticed. Specificity corresponds to 100% and sensitivity to 78.6%.

Abstract
SummaryThe cyclic anhydride (CA) and the mixed anhydride (MA) of DTPA were synthesized and used to chelate 111In to an antimelanoma monoclonal antibody. The CA and MA methods showed mean labeling efficiencies of 25.7 and 20.5%, respectively (p = NS). The binding efficiency of labeled antibody to human melanoma cells in tissue culture also was similar (x̄ = 52 and 50%, respectively, p = NS), as was tumor uptake in nude mice at 96 hrs post-injection (16%-CA vs 12%-MA). The method required less complicated chemical syntheses, much less preparation time, and the product was stable over a much longer period. The results suggest that the CA method is preferable for bifunctional chelate labeling of monoclonal antibodies with 111In-DTPA.

Abstract
The seventh Edition of "Innovative Therapy, Monoclonal Antibodies and Beyond" Meeting took place in Milan, Italy, on January 27, 2017. The two sessions of the meeting were focused on: 1) Preclinical assays and novel biotargets; and 2) monoclonal antibodies, cell therapies and targeted molecules. Between these two sessions, a lecture entitled "HLA-antigens modulation and response to immune checkpoint inhibitor immunotherapy" was also presented. Despite the impressive successes in cancer immunotherapy in recent years, the response to immune based interventions occurs only in a minority of patients (∼20%). Several basic and translational mechanisms of resistance to immune checkpoint blockers (ICBs) were discussed during the meeting: 1. the impact of tumor microenvironment on the activity of immune system; 2. strategies to inhibit the cross-talk between extracellular matrix and myeloid-derived suppressor cells (MDSC) in the preclinical setting; 3. microRNA expression as a biomarker and as a target of therapy in non-small cell lung cancer (NSCLC); 4. the significance of complement activation pathways in response to immune checkpoint inhibitors; 5. the immunosuppressive activity of the microbiota by inducing IL-17 producing cells; and 6. modulation of HLA antigens as possible markers of response to ICB therapy. In order to overcome the deficiency in active anti-tumor T cells, several clinically applicable combination strategies were also discussed: 1. strategies to enhance the anticancer effects of immunogenic cell death inducing-chemotherapy; 2. the use of CAR T-cells in solid tumors; 3. the use of combination strategies involving oncolytic viruses and ICBs; 4. combinations of new ICBs with anti-PD-1/CTLA-4 therapy; and 4. combinations of targeted therapies and ICBs in melanoma. Overall, this conference emphasized the many novel strategies that are being investigated to improve the overall patient response to cancer immunotherapy. Optimization of biomarkers to accurately select patients who will respond to immunotherapy, coupled with combination strategies to improve long term patient survival remain critical challenges in the immuno-oncology field.

Abstract
Reported post-surgery 1-year survival rate for oral canine malignant melanoma (cMM) is around 30%; novel treatments are needed as the role of adjuvant chemotherapy is unclear. This prospective study regards adjuvant electrovaccination with human chondroitin sulfate proteoglycan-4 (hCSPG4)-encoded plasmid in 23 dogs with resected II/III-staged CSPG4-positive oral cMM compared with 19 dogs with resected only II/III-staged CSPG4-positive oral cMM. Vaccination resulted in 6-, 12-, 18- and 24-month survival rate of 95.6, 73.9, 47.8 and 30.4%, respectively [median survival time (MST) 684 days, range 78-1694, 8 of 23 dogs alive] and 6-, 12-, 18- and 24-month disease-free interval (DFI) rate of 82.6, 47.8, 26.1 and 17.4%, respectively (DFI 477 days, range 50-1694). Non-vaccinated dogs showed 6-, 12-, 18- and 24-month survival rate of 63.2, 26.3, 15.8 and 5.3%, respectively (MST 200 days, range 75-1507, 1 of 19 dogs alive) and 6-, 12-, 18- and 24-month DFI rate of 52.6, 26.3, 10.5 and 5.3%, respectively (DFI 180 days, range 38-1250). Overall survival and DFI of vaccinated dogs was longer in those <20 kg. In vaccinated and non-vaccinated dogs local recurrence rate was 34.8 and 42%, respectively while lung metastatic rate was 39 and 79%, respectively.

Abstract
The non-classical human leukocyte antigen (HLA) Class I molecule HLA-G is best known for its tolerogenic function at the maternal-fetal interface, where it protects the fetus from destruction by the immune system of its mother. Yet, HLA-G has been the topic of intense investigations and its functions reach much further than originally believed. International conferences on HLA-G have taken place every 3 years since 1998, and the Sixth International Conference on HLA-G, that took place in Paris in July 2012. It counted 180 attendees from 28 countries, 35 speakers in plenary sessions, and 63 presentations of research in symposia and poster sessions, bringing new insight in HLA-G research. Here we summarize the major advances on the function and nature of HLA-G molecule that were reported, with particular interest on the findings in new mechanisms of action through regulatory cells, its relevance in cancer as well as in the molecular structure and functions of HLA-G, which are key for its clinical application.

Abstract
DR ANTIGENS are polymorphic cell surface molecules whose expression is controlled by a locus closely linked or identical to the D locus of the major histocompatibility complex (MHC) of man (for reviews see refs 1, 2). They are functionally and structurally homologous to the murine la antigens determined by the I-E subregion of the MHC, a region which has been implicated in the genetic control of immune responses(3,4). Both sets of antigens are mainly expressed on cells associated with immune function (for reviews see refs 1, 2, 5), and are involved in mediating T-cell, B-cell and macrophage interactions required for the generation of immune responses(6-9). In addition, both consist of two non-covalently associated polypeptides, designated alpha and beta, with molecular weights of 34,000 and 28,000, respectively(10). The association of some DR antigens with increased susceptibility to certain diseases (for review see ref. 1) and the genetic restrictions imposed on cellular interactions by the HLA-D region(9,11) may represent the effects of structural variability among DR antigens. The aim of the studies reported here was to examine the nature and degree of structural variation among DR antigens isolated from cultured lymphoid B cells with different DR phenotypes. Such information may provide an understanding of the molecular mechanisms by which DR antigens mediate their function.

Abstract
Background: The availability of molecular-targeted therapies for the treatment of melanoma has emphasised the need to identify mutations in target genes such as BRAF and KIT. Circulating tumour cells (CTC) are present in the peripheral blood of a significant proportion of cancer patients. Methods: High molecular weight melanoma-associated antigen (HMW-MAA) was used to isolate melanoma cells from peripheral blood as it is selectively expressed at high levels on melanomas. The HMW-MAA-positive cells were isolated using immunomagnetic beads. After removing CD45+ cells, CTC were identified by staining with MART-1- and gp100-specific antibodies (HMW-MAA+, CD45−, MART-1/gp100+). Single, isolated CTC were then subjected to BRAF and KIT mutational analysis. Results: CTC (HMW-MAA+, CD45−, MART-1/gp100+) were isolated from the blood of 11 patients and BRAF and KIT were sequenced in nine and four patients, respectively. The BRAF sequences identified in the CTC were inconsistent with those identified in autologous melanoma tumours in three patients and the KIT sequences were inconsistent in three patients. In addition, polyclonal BRAF mutations were identified in one patient and concomitant mutations in BRAF and KIT were identified in another patient. Conclusion: Melanoma cells show clonal heterogeneity. Therefore, CTC genotyping may be crucial for successful molecular-targeted therapy.

Abstract
Chondroitin sulfate proteoglycan 4 (CSPG4), also known as High Molecular Weight-Melanoma Associated Antigen, is a cell surface proteoglycan which has been recently shown to be expressed not only by melanoma cells, but also by various types of human carcinoma and sarcoma. Furthermore, at least in squamous cell carcinoma of head and neck and in basal breast carcinoma, CSPG4 is expressed by cancer stem cells. CSPG4 plays an important role in tumor cell growth and survival. These CSPG4-associated functional properties of tumor cells are inhibited by CSPG4-specific monoclonal antibodies (mAb) in vitro. Moreover, CSPG4-specific mAb can also inhibit tumor growth and metastasis in vivo. The anti-tumor effects of CSPG4-specific mAb are likely to reflect the blocking of important migratory, mitogenic and survival signaling pathways in tumor cells. These results indicate that CSPG4 is a promising new target to implement mAb-based immunotherapy of various types of cancer.

Abstract
Major histocompatibility complex (MHC) class I chain-related gene A (MICA), a ligand for the activating immunoreceptor natural killer group 2D (NKG2D), is expressed on stressed cells such as tumor cells. Study of expression of this molecule on tumor cells and patients' sera is useful to define patients' stages leading to proper selection of therapy. In this study, mouse anti-MICA monoclonal antibodies (mAbs) were produced by DNA immunization using a gene gun. Screening of anti-MICA-producing mouse and hybridomas were performed by immunoblot and cell enzyme-linked immunosorbent assay (ELISA) against MICA-positive HeLa and -negative Me1386 cell lines. MAbs were characterized against MICA-positive and -negative cell lines by immunoblot, cell ELISA and flow cytometry. The mAbs were also characterized for locus and allele specificities of MICA and MHC class I chain-related gene B (MICB) as well as for their ability to stain formalin-fixed paraffin-embedded tissues by immunohistochemistry. Although all mouse immune sera were positive with MICA-positive cells by both immunoblot and cell ELISA methods, some hybridomas were positive only with one method. The mAbs had diverse specificities to detect MICA and MICB and different abilities to stain formalin-fixed paraffin-embedded tissues. Thus, DNA immunization by gene gun is an effective method to generate immune mice for the production of mAbs with a variety of specificities against native and denatured forms of MIC proteins.

Abstract
Changes in classical and nonclassical HLA class I as well as HLA class II antigens have been identified in malignant lesions. These changes, which are described in this review are believed to play a major role in the clinical course of the disease since both HLA class I and class II antigens are critical to the interaction between tumor cells and components of both innate and adaptive immune system. Abnormalities in HLA antigen expression in malignant cells, which range in frequency from 0-90%, are caused by distinct mechanisms. They include defects in beta(2)-microglobulin (beta(2)m) synthesis, loss of the gene(s) encoding HLA antigen heavy chain(s), mutations, which inhibit HLA antigen heavy chain transcription or translation, defects in the regulatory mechanisms, which control HLA antigen expression and/or abnormalities in one or more of the antigen processing, machinery (APM) components. More recently, epigenetic events associated with tumor development and progression have been found to underlie changes in HLA antigen, APM component, costimulatory molecule and tumor antigen (TA) expression in malignant cells. The types of epigenetic modifications that may occur in normal and malignant cells as well as their role in changes in HLA antigen expression by malignant cells have been reviewed. The epigenetic events associated with alterations in HLA antigen expression may be clinically relevant as, in some cases, they have been shown to impair the recognition of tumor cells by components of the adaptive immune system. The functional relevance and potential clinical significance of these epigenetic alterations have been addressed. Finally, unlike genetic alterations, epigenetic modifications can, in some cases, be reversed with pharmacologic agents that induce DNA hypomethylation or inhibit histone deacetylation. Therefore, strategies to overcome epigenetic modifications underlying changes in HLA antigen expression in malignant cells have been discussed.

Abstract
The crucial role played by human leukocyte antigen (HLA) antigens and natural killer (NK)-cell-activating ligands in the interactions of malignant cells with components of the host's immune system has stimulated interest in the characterization of their expression by malignant cells. Convincing evidence generated by the immunohistochemical staining of surgically removed malignant lesions with monoclonal antibodies recognizing HLA antigens and NK-cell-activating ligands indicates that the surface expression of these molecules is frequently altered on malignant cells. These changes appear to have clinical significance because in some types of malignant disease they are associated with the histopathological characteristics of the lesions as well as with disease-free interval and survival. These associations have been suggested to reflect the effect of HLA antigen and NK-cell-activating ligand abnormalities on the interactions of tumor cells with antigen-specific cytotoxic T lymphocytes (CTL) and with NK cells. Nevertheless, there are examples in which disease progresses in the face of appropriate HLA antigen and/or NK-cell-activating ligand as well as tumor antigen expression by malignant cells and of functional antigen-specific CTL in the investigated patient. In such scenarios, it is likely that the tumor microenvironment is unfavorable for CTL and NK cell activity and contributes to tumor immune escape. Many distinct escape mechanisms have been shown to protect malignant cells from immune recognition and destruction in the tumor microenvironment. In this article, following the description of the structural and functional characteristics of soluble HLA antigens and NK-cell-activating ligands, we will review changes in their serum level in malignant disease and discuss their potential role in the escape mechanisms used by tumor cells to avoid recognition and destruction.

Abstract
PURPOSE To characterize HLA class I antigen expression in non-small cell lung cancer (NSCLC) lesions, and to assess the clinical significance of these molecules' downregulation. METHODS One hundred and ninety primary formalin fixed, paraffin embedded NSCLC lesions were stained with HLA class I heavy chain-specific mAb HC-10. Results were scored as percentage of stained tumor cells and categorized into three groups: 0-24% (negative), 25-75% (heterogeneous) and >75% (positive). HLA class I antigen expression was correlated with clinical and pathologic predictors of time to progression and survival and analyzed using the chi-square test. Association between HLA class I antigen expression and survival was assessed using Cox regression models, while controlling for confounders. RESULTS HLA class I antigen expression was negative, heterogeneous and positive in 153, 25 and 12 primary NSCLC lesions, respectively. Independent variables significantly associated with survival included tumor stage, PS and weight loss. The median survival times were 40.6, 44.0 and 17.9 months for patients with a HLA class I antigen expression scored as negative, heterogeneous and positive, respectively. CONCLUSION HLA class I antigen defects were found with high frequency (93.6%) in NSCLC lesions. HLA class I antigen downregulation was associated with improved survival, although this association was not statistically significant. These results, which parallel similar findings in uveal melanoma and in breast carcinoma, raise the possibility that NK cells may play a role in the control of NSCLC tumors.

Abstract
The human high molecular weight-melanoma associated antigen (HMW-MAA) is a membrane-bound chondroitin sulfate proteoglycan that is variably expressed in a high percentage of melanoma cell lines and tumors. Since the mechanism(s) regulating HMW-MAA expression has(ve) not been defined, in this study, we have examined whether promoter DNA methylation regulates the level of HMW-MAA expression. In melanoma cell lines, the level of HMW-MAA mRNA and protein expression is coordinately regulated, implicating a transcriptional control mechanism. Consistent with a role for regulation by DNA methylation, we have found that a dense CpG island flanks the human HMW-MAA gene transcriptional start site. Methylation-specific PCR and sodium bisulfite DNA sequencing analyses indicate that the HMW-MAA promoter is heavily methylated in melanoma cell lines, melanoma lesions and normal lymphocytes that do not express HMW-MAA; in contrast, the HMW-MAA promoter is not methylated in melanoma cell lines and tumors that express this antigen. In addition, HMW-MAA expression is markedly induced in HMW-MAA-negative melanoma cell lines by incubation with the DNA methyltransferase inhibitor 5-aza-2'-deoxycytidine. In summary, our results establish DNA methylation as a key regulator of HMW-MAA expression by human melanoma cells. This information represents a useful background to optimize immunotherapeutic strategies targeting HMW-MAA.

Abstract
Delta (Y), MB1 (X), and Z are the three catalytic beta-subunits located in the inner rings of the constitutive proteasome, an intracellular multicatalytic complex responsible for the generation of peptides presented by human leukocyte antigen (HLA) class I antigens to T cells. When cells are incubated with interferon-gamma, delta (Y), MB1 (X), and Z are replaced by LMP2, LMP7, and LMP10, respectively, leading to the expression of immunoproteasome which generates peptides with increased affinity for HLA class I antigens. The characterization of the expression of constitutive proteasome and immunoproteasome subunits in cells, normal tissues, and malignant lesions has been hampered by the lack or limited availability of constitutive proteasome and immunoproteasome subunit-specific monoclonal antibodies (mAbs), which are suitable for immunohistochemical staining. To overcome this limitation, we generated human delta (Y), MB1 (X), Z, LMP2, LMP7, and LMP10-specific mAb-secreting hybridomas from BALB/c mice immunized with peptides and recombinant fusion proteins. The mAbs SY-5, SJJ-3, NB-1, SY-1, HB-2, and TO-7 were shown to be specific for delta (Y), MB1 (X), Z, LMP2, LMP7, and LMP10, respectively, as they react specifically with the corresponding molecules when tested with a human B lymphoid LG2 cell lysate in Western blotting and with the peptide derived from each molecule in enzyme-linked immunosorbent assay. The reactivity of the six mAbs with the corresponding intracellular antigens resulted in intracellular staining when the mAbs were tested with microwave-treated and saponin-permeabilized cells in indirect immunofluorescence and with formalin-fixed, paraffin-embedded tissue sections in immunohistochemical reactions. These results suggest that the constitutive proteasome and immunoproteasome subunit-specific mAbs we have developed are useful probes to characterize the expression of proteasome subunits in normal tissues and in pathological lesions.

Abstract
The analysis of human leukocyte antigen (HLA) class I allospecificity expression in malignant lesions has been hampered by the limited availability of HLA class I allospecificity-specific monoclonal antibodies (mAbs) which stain tissues in immunohistochemical (IHC) reactions. During the 12th International Histocompatibility Workshop, the HLA and cancer component made available a panel of mAbs capable of detecting monomorphic, locus- and allo-specific HLA class I antigenic determinants in surgically removed frozen tissue sections by IHC staining. In the present study, we have utilized this panel of mAbs to analyze the expression of HLA class I allospecificities in 33 primary and in 11 metastatic lesions surgically removed from HLA-typed patients with malignant melanoma, as this information contributes to determine the extent of HLA class I antigen abnormalities in melanoma lesions. HLA class I antigens were downregulated in six (18.2%) of the primary lesions and in six (54.5%) of the metastatic lesions. Selective loss of HLA-A and HLA-B antigens was detected in two (6.1%) and in one (3.0%), respectively, of the primary lesions, but in none of the metastases. HLA-A and HLA-B antigens were downregulated in three (9.1%) and four (36.4%) of the primary and metastatic lesions, respectively. Selective loss of one or more HLA class I allospecificities was found in 10 (33.0%) and two (18.0%) of the 33 primary and 11 metastatic melanoma lesions analyzed, respectively. HLA class I antigen abnormalities were present in 16 (48.5%) of the 33 primary lesions analyzed (i.e. six lesions demonstrating abnormal reactivity with HLA class I monomorphic-specific mAb, two lesions demonstrating selective abnormal reactivity with HLA-B locus-specific mAb, one lesion demonstrating selective abnormal reactivity with HLA-A and HLA-B locus-specific mAbs, and seven lesions demonstrating selective abnormal reactivity with HLA class I allele-specific mAb). Furthermore, HLA class I antigen abnormalities were present in nine (81.8%) of the 11 metastatic lesions analyzed (i.e. six lesions demonstrating abnormal reactivity with HLA class I monomorphic-specific mAb, one lesion demonstrating selective abnormal reactivity with HLA-A locus-specific mAb, and two lesions demonstrating selective abnormal reactivity with HLA class I allele-specific mAb). It cannot be ruled out that the frequency of HLA class I allospecificity abnormalities is higher, as the expression of several HLA class I allospecificities could not be investigated because of the lack of appropriate probes. The frequency of HLA class I antigen defects in primary lesions was significantly correlated with primary lesion thickness, an important prognostic marker in melanoma, arguing for a potential clinical significance of HLA class I antigen abnormalities in melanoma. In conclusion, the results of the present study (i) demonstrate that the frequency of HLA class I allospecificity abnormalities in primary melanoma lesions is markedly higher than that of total HLA class I antigen downregulation described in the literature; (ii) corroborate our previous findings that staining of melanoma lesions with mAb to monomorphic determinants of HLA class I antigens does not detect selective HLA class I allospecificity loss; and (iii) demonstrate for the first time selective loss of antigenic determinants expressed on HLA class I molecules in melanoma lesions. The latter finding indicates that at least two mAbs recognizing distinct antigenic determinants on the HLA molecule being investigated should be used for IHC staining of tissue sections in order to prove that lack of immunostaining reflects actual loss of the corresponding HLA molecule and not selective loss of antigenic determinants.

Abstract
Endoplasmic reticulum (ER) chaperones of the antigen processing machinery play a crucial role in HLA class I antigen complex assembly and antigen presentation. The characterization of the expression of these chaperones in normal tissues and malignant lesions has been hampered by the lack or limited availability of ER chaperone-specific monoclonal antibodies (mAb) that are suitable for immunohistochemical staining. To overcome this limitation, we have generated human calnexin, ERp57, calreticulin and tapasin-specific mAb-secreting hybridomas from BALB/c mice immunized with peptides and recombinant proteins. The mAb TO-5, TO-2, TO-11 and TO-3 were shown to be specific for calnexin, ERp57, calreticulin and tapasin, respectively, as they react specifically with the corresponding immunizing peptides in ELISA and with the corresponding proteins when tested with human lymphoid cell lysates in Western blotting. Furthermore, the reactivity of the four mAb with the corresponding intracellular antigens yielded intracellular staining when the mAb were tested with formalin-fixed, microwave-treated and saponin-permeabilized cells in indirect immunofluorescence and with formalin-fixed, paraffin-embedded tissue sections in the immunoperoxidase reaction. These results suggest that the ER chaperone-specific mAb we have developed are useful probes for characterizing the expression of ER chaperones of the antigen processing machinery in normal and pathological cells. This information will contribute to defining the effects of abnormalities in their expression on HLA class I antigen expression and function and on the interactions of target cells with the host's immune system.

Abstract
Only three anti-HLA-A monoclonal antibodies (mAbs) have been described in the literature. Two of them recognize determinants shared by only a few HLA-A allospecificities. The third one, mAb 3G11, recognizes a determinant shared by most HLA-A allospecificities. Being an IgM, the latter mAb is not likely to be a useful probe in immunohistochemical reactions and in functional assays. Therefore, in the present study we have characterized the specificity of the mAbs LGIII-147.4.1 and LGIII-220.6.2. The two mAbs that do not share idiotypic determinants recognize distinct but spatially close antigenic determinants expressed on most of the gene products of the HLA-A locus. Specifically, the determinant recognized by mAb LGIII-220.6.2 is expressed on HLA-A1, -A2, -A3, -A26, -A28, -A29, -A30, -A33, -A36, -A74 and -A80 allospecificities. The determinant recognized by mAb LGIII-147.4.1, which appears to be located on the amino-acid residues 79-83 of the heavy chain, is expressed on all HLA-A allospecificities but HLA-A23, -A24, -A25 and -A32. Because of its broad reactivity, the mAb LGIII-147.4.1 was characterized in a number of assays. It was found to be a useful probe to measure the HLA-A antigen level in serum, to assess the HLA-A restriction of cytotoxic T lymphocytes (CTL) and to monitor HLA-A antigen expression in normal and malignant lesions.

Abstract
Human leukocyte antigen (HLA) Class II antigens are variably expressed on acute myeloid leukemia (AML) blasts. The biological and clinical significance of HLA Class II antigen expression by AML cells is not known. Therefore, we sought to characterize cases of AML without detectable HLA-DR expression. Samples from 248 consecutive adult AML patients were immunophenotyped by multiparameter flow cytometry at diagnosis. HLA-DR antigens were not detected on AML cells from 43 patients, including 20 with acute promyelocytic leukemia (APL), and 23 with other subtypes of AML. All APL cases had t(15;17), but there were no characteristic chromosome abnormalities in non-APL cases. No direct expression of other antigens was identified in HLA-DR-negative APL and non-APL cases. Interestingly, cells from three HLA-DR-negative non-APL patients had similar morphology to that of the hypogranular variant of APL. This morphology, however, was not present in any HLA-DR-positive AML cases. Treatment response was similar in the 23 HLA-DR-negative non-APL and the 205 HLA-DR-positive patients. Finally, relapse was infrequently associated with changes in HLA-DR antigen expression, as the HLA-DR antigen was lost at relapse in only 4% of HLA-DR-positive cases, and was gained at relapse in only 17% of HLA-DR-negative cases. We conclude that HLA-DR-negative AML includes approximately equal numbers of APL and non-APL cases, and that the morphology of HLA-DR-negative non-APL cases can mimic the hypogranular variant of APL. The diagnosis of APL cannot be based on morphology and lack of HLA-DR antigen expression; rather, it requires cytogenetic or molecular confirmation.

Abstract
Sequence analyses of the transporter associated with antigen processing (TAP) in tumor cell lines with deficient MHC class I surface expression identified a bp deletion at position 1489 near the ATP-binding domain of Tap1, causing a frameshift in one melanoma cell line. The impaired TAP1 protein expression was associated with deficient TAP2 protein expression, peptide binding, translocation, and MHC class I surface expression. Stable TAP1 gene transfer reconstitutes the described defects, whereas lysis by HLA-A2-restricted CTLs was still abrogated. This was attributable to a 2-bp insertion at position 890 in the HLA-A2 gene and was corrected after HLA-A2 cotransfection. This study describes for the first time mutations in two distinct components of the MHC class I antigen processing pathway, suggesting an immune selection against CTLs recognizing both TAP-dependent and -independent T-cell epitopes.

Abstract
PURPOSE Malignant transformation of cells is frequently associated with abnormalities in human leukocyte antigen (HLA) expression. These abnormalities may play a role in the clinical course of the disease, because HLA antigens mediate interactions of tumor cells with T cells and NK cells. Uveal melanoma is a highly malignant tumor of the eye and is characterized by a hematogenic spread to the liver. Little is known about the role of HLA expression in progression of this malignant disease. METHODS In the present study HLA class I antigen, beta(2)-microglobulin (beta(2)-m), and HLA class II antigen expression was analyzed in primary uveal melanoma lesions by immunoperoxidase staining with monoclonal antibodies of 65 archival clinical samples. The results were correlated with the clinical course of the disease. RESULTS HLA class I antigen expression and beta(2)-m expression were downregulated in 40 and 35 lesions, respectively. HLA class II antigens were expressed in 30 lesions. Patients with high HLA class I, including beta(2)-m, and HLA class II antigen expression in their primary melanoma lesions had a significantly decreased survival (P = 0.009, P < 0.001, and P = 0.006, respectively). CONCLUSIONS The findings argue against a major role of cytotoxic T-lymphocyte (CTL)-mediated control of tumor growth in the clinical course of uveal melanoma and are compatible with a potential role of NK-cell-mediated control of hematogenic metastatic spread.

Abstract
BACKGROUND The nonclassic human major histocompatibility complex class I antigens human leukocyte antigen (HLA)--G are proposed to protect tumor cells from natural killer cell lysis. In the current study, the authors measured soluble HLA-G molecules (sHLA-G) in serum from patients with malignant melanoma. METHODS Soluble HLA-G was determined in serum samples of 190 melanoma patients with various stages of disease, with or without current therapy including interferon (IFN)-alpha and different cytostatics in comparison to 126 healthy controls by using a two-step enzyme-linked immunoadsorbent assay. RESULTS Serum sHLA-G was significantly (P < 0.0005) elevated in melanoma patients (mean +/- standard error of the mean [SEM] = 41.95 +/- 2.15 ng/mL) compared with healthy controls (mean +/- SEM = 22.92 +/- 1.51 ng/mL). Univariate analysis revealed a correlation of sHLA-G serum level with advanced stages of disease (P < 0.001) and tumor load (P < 0.05). Patients undergoing immunotherapy with IFN-alpha (n = 31) showed an increased serum sHLA-G (mean +/- SEM = 62.05 +/- 7.58 ng/mL; P < 0.0005), whereas other treatment regimens (n = 24) did not influence sHLA-G serum concentrations. Multivariate analysis revealed treatment with IFN-alpha as the only impact factor for elevated serum sHLA-G, lacking any correlation with stage of disease or tumor burden. Furthermore, IFN-alpha was found to upregulate HLA-G cell surface expression on circulating monocytes. sHLA-G serum level was not associated with recurrence free or overall survival. CONCLUSIONS This study shows increased sHLA-G serum concentrations in melanoma patients and additional enhancement upon treatment with IFN-alpha. The level of serum sHLA-G, however, had no negative impact on patients' prognosis.

Abstract
The realization that tumor cells utilize multiple mechanisms to escape from immune recognition and destruction has stimulated interest in developing and applying immunotherapeutic strategies which target both humoral and cellular immunity to malignant cells. As a result, the tumor-associated antigens (TAA) used as targets have to be expressed on the cell surface membrane of malignant cells. Furthermore, since most of the TAA used for active specific immunotherapy are self-antigens, a challenge facing tumor immunologists is to develop strategies which are effective in breaking tolerance to self-antigens. This chapter describes one strategy which relies on the use of peptide mimics of the human high-molecular-weight melanoma-associated antigen (HMW-MAA) as immunogens to implement active specific immunotherapy in patients with malignant melanoma. These mimics, which are isolated from phage display peptide libraries by panning with anti-HMW-MAA monoclonal antibodies, are expected to induce both humoral and cellular anti-HMW-MAA immunity.
