Abstract
Multiple myeloma (MM)as a haematological malignancy is still incurable. In addition to the presence of somatic genetic mutations in myeloma patients, the presence of immunosuppressive microenvironment greatly affects the outcome of treatment. Although the discovery of immunotherapy makes it possible to break the risk of high toxicity and side effects of traditional chemotherapeutic drugs, there are still obstacles of ineffective treatment or disease recurrence. In this review, we discuss therapeutic strategies to further enhance the specific anti-tumor immune response by activating the immunogenicity of MM cells themselves. New ideas for future myeloma therapeutic approaches are provided.

Abstract
Immunotherapeutic approaches, including adoptive cell therapy, revolutionized treatment in multiple myeloma (MM). As dendritic cells (DCs) are professional antigen-presenting cells and key initiators of tumor-specific immune responses, DC-based immunotherapy represents an attractive therapeutic approach in cancer. The past years, various DC-based approaches, using particularly ex-vivo-generated monocyte-derived DCs, have been tested in preclinical and clinical MM studies. However, long-term and durable responses in MM patients were limited, potentially attributed to the source of monocyte-derived DCs and the immunosuppressive bone marrow microenvironment. In this review, we briefly summarize the DC development in the bone marrow niche and the phenotypical and functional characteristics of the major DC subsets. We address the known DC deficiencies in MM and give an overview of the DC-based vaccination protocols that were tested in MM patients. Lastly, we also provide strategies to improve the efficacy of DC vaccines using new, improved DC-based approaches and combination therapies for MM patients.

Abstract
Multiple myeloma is a plasma cell malignancy that primarily affects the elderly. The global burden of multiple myeloma is increasing in many countries due to an aging population. Despite recent advances in therapy, myeloma remains an incurable disease, highlighting the pressing need for new therapies. Accumulating evidence supports that triggering the host immune system is a critical therapeutic mechanism of action by various anti-myeloma therapies. These anti-myeloma therapies include proteasome inhibitors, immunomodulatory drugs, monoclonal antibody drugs, and autologous stem cell transplantation. More recently, T cell-based immunotherapeutics (including chimeric antigen receptor T-cell therapies and bispecific T-cell engagers) have shown dramatic clinical benefits in patients with relapsed or refractory multiple myeloma. While immune-based therapeutic approaches are recognized as key modalities for improved clinical outcomes in myeloma patients, understanding the immune system in multiple myeloma patients remains elusive. The cancer-immunity cycle is a conceptual framework illustrating how immune cells recognize and eliminate tumor cells. Based on this framework, this review will provide an overview of the immune system in multiple myeloma patients and discuss potential therapeutic approaches to stimulate anti-tumor immunity.

Abstract
Despite new efficacy drugs and cell therapy have been used for multiple myeloma (MM) patients, some patients will relapse over time. We wonder the immune system play a vital role as well as MM cell during the development of disease. It is clear that the characteristic of myeloma cell is associated with the survival of MM patients. However, the link between the immune profiling and the prognosis of the disease is still not entirely clear. As more study focus on the role of immunity on multiple myeloma pathogenesis. There are plenty of study about the predictive role of immunity on the survival of multiple myeloma patients. Up to mow, the majority reviews published have focused on the immunotherapy and immune pathogenesis. It is indispensable to overlook the predictive role of immunity on multiple myeloma patients. Here, we give a review of vital previous works and recent progress related to the predictive role of immune profiling on multiple myeloma, such as absolute lymphocyte count, neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, lymphocytes and cytokines.

Abstract
Despite the improvement of patient's outcome obtained by the current use of immunomodulatory drugs, proteasome inhibitors or anti-CD38 monoclonal antibodies, multiple myeloma (MM) remains an incurable disease. More recently, the testing in clinical trials of novel drugs such as anti-BCMA CAR-T cells, antibody-drug conjugates or bispecific antibodies broadened the possibility of improving patients' survival. However, thus far, these treatment strategies have not been able to steadily eliminate all malignant cells, and the aim has been to induce a long-term complete response with minimal residual disease (MRD)-negative status. In this sense, approaches that target not only myeloma cells but also the surrounding microenvironment are promising strategies to achieve a sustained MRD negativity with prolonged survival. This review provides an overview of current and future strategies used for immunomodulation of MM focusing on the impact on bone marrow (BM) immunome.

Potent anti-myeloma efficacy of dendritic cell therapy in combination with pomalidomide and programmed death-ligand 1 blockade in a preclinical model of multiple myeloma.

Abstract
Dendritic cell (DC)-based vaccines are recognized as a promising immunotherapeutic strategy against cancer; however, the efficacy of immunotherapy with DCs is controlled via immune checkpoints, such as programmed death-ligand 1 (PD-L1). PD-L1 expressed on DC and tumor cells binds to programmed death-1 (PD-1) receptors on the activated T cells, which leads to the inhibition of cytotoxic T cells. Blocking of PD-L1 on DC may lead to improve the efficacy of DC therapy for cancer. Here we demonstrated that DC vaccination in combination with pomalidomide and programmed death-ligand 1 (PD-L1) blockade inhibited tumor growth of a multiple myeloma (MM) mouse model. DCs + pomalidomide with dexamethasone + PD-L1 blockade significantly inhibited immune immunosuppressive factors and promoted proportions of immune effector cells in the spleen and tumor microenvironment. Additionally, functional activities of cytotoxic T lymphocytes and NK cells in spleen were enhanced by DCs + pomalidomide with dexamethasone + PD-L1 blockade. Taken together, this study identifies a potential new therapeutic approach for the treatment of MM. These results also provide a foundation for the future development of immunotherapeutic modalities to inhibit tumor growth and restore immune function in MM.

Abstract
Over the past two decades nanotechnology has become an important part of novel medical research. Researchers have made great progress in developing nanotechnology applications used for detecting and treating oncological diseases. Recently, many research groups have focused on the use of superparamagnetic iron oxide nanoparticles (SPIONs) in cancer treatment. Due to the range of therapeutic properties and possibilities of various modifications, SPIONs are a promising and multifunctional tool in various cancer therapies and may help to overcome the limitations of conventional therapies. Moreover, it is still necessary to develop new methods of treatment with expected properties, such as lower toxicity, long-lasting effectiveness and higher selectivity. Analyzing the literature data, we found that currently SPIONs are used in the transport of drugs, immunotherapy and hyperthermia. The main aim of this review is to present various cancer treatment therapies utilizing SPIONs, the importance of the experiments carried out by research groups and further perspectives in the nanotechnological use of SPIONs.

Abstract
Multiple myeloma (MM) is usually diagnosed in older adults at the time of immunosenescence, a collection of age-related changes in the immune system that contribute to increased susceptibility to infection and cancer. The MM tumor microenvironment and cumulative chemotherapies also add to defects in immunity over the course of disease. In this review we discuss how mouse models have furthered our understanding of the immune defects caused by MM and enabled immunotherapeutics to progress to clinical trials, but also question the validity of using immunodeficient models for these purposes. Immunocompetent models, in particular the 5T series and Vk⁎MYC models, are increasingly being utilized in preclinical studies and are adding to our knowledge of not only the adaptive immune system but also how the innate system might be enhanced in anti-MM activity. Finally we discuss the concept of immune profiling to target patients who might benefit the most from immunotherapeutics, and the use of humanized mice and 3D culture systems for personalized medicine.

Abstract
Cellular immunotherapy is emerging as a potential immunotherapeutic modality in multiple myeloma (MM). We have developed potent immunotherapeutic agent (VAX-DC/MM) generated by dendritic cells (DCs) loaded with autologous myeloma cells irradiated with ultraviolet B. In this study, we evaluated the safety and efficacy of VAX-DC/MM in patients with relapsed or refractory MM. This trial enrolled relapsed or refractory MM patients who had received both thalidomide- and bortezomib-based therapies. Patients received the intradermal VAX-DC/MM injection every week for 4 weeks. Patients were treated with 5 × 106 or 10 × 106 cells, with nine patients treated at a higher dose. The median time from diagnosis to VAX-DC/MM therapy was 56.6 months (range, 28.5–130.5). Patients had received a median of five prior treatments, and 75% had received autologous stem cell transplantation. VAX-DC therapy was well-tolerated, and the most frequent adverse events were local reactions at the injection site and infusion-related reactions. In seven of nine patients who received 10×106 cells, an immunological response (77.8%) was observed by interferon-gamma ELISPOT assay or a mixed lymphocyte reaction assay for T-cell proliferation. The clinical benefit rate was 66.7% including one (11.1%) with minor response and five (55.6%) with stable disease; three (33.3%) patients showed disease progression. In conclusion, VAX-DC/MM therapy was well-tolerated, and had disease-stabilizing activity in heavily pretreated MM cases. Further studies are needed to increase the efficacy of VAX-DC/MM in patients with MM.

Abstract
Dendritic cells (DC)-based vaccines are considered useful in cancer immuno-therapy, and the interactions of DC and dying tumor cells are important and promising for cancer immunotherapy. We investigated whether chaetocin could be used to induce death of myeloma cells, for loading onto DCs can affect DCs function. In this study, we show that the dying myeloma cells treated with chaetocin resulted in the induction of heat shock protein (HSP) 90, which was inhibited by antioxidant N-acetyl cysteine, and showed an increase in the expression of MAGE-A3 and MAGE-C1/CT7. DCs loaded with chaetocin-treated dying myeloma cells produced low levels of IL-10 and enhanced the cross presentation of DCs. Additionally, these DCs most potently inhibited regulatory T cells, induced Th1 polarization and activated myeloma-specific cytotoxic T lymphocytes compared with DCs loaded with UVB-irradiated dying myeloma cells. These results suggest that the pretreatment of myeloma cells with chaetocin can enhance DC function through the up-regulation of HSP90 and cancer testis antigens in dying myeloma cells and can potently induce the Th1 polarization of DCs and myeloma-specific cytotoxic T lymphocytes.

Abstract
Previous studies have demonstrated that pullulan, a polysaccharide purified from Aureobasidium pullulans, has immune-stimulatory effects on T and B cells. Moreover, pullulan has been used as a carrier in the delivery of the antigen (Ag) peptide to lymphoid tissues. However, the in vivo effect of pullulan on dendritic cells (DC) has not been well characterized. In this study, we assessed the effect of pullulan on DC activation and anti-cancer immunity. The results showed that the pullulan treatment up-regulated co-stimulatory molecule expression and enhanced pro-inflammatory cytokine production in bone marrow-derived DCs (BMDC) in vitro and in spleen DCs in vivo. Moreover, the combination of ovalbumin (OVA) and pullulan induced OVA antigen-specific T cell activations in vivo. In tumor-bearing mice, pullulan induced the maturation of DCs in spleen and tumor draining lymph node (drLN), and promoted the OVA-specific T cell activation and migration of the T cells into the tumor. In addition, the combination of OVA and pullulan inhibited B16-OVA tumor growth and liver metastasis. The combination of tyrosinase-related protein 2 (TRP2) peptide and pullulan treatment also suppressed B16 melanoma growth. Thus, the results demonstrated that pullulan enhanced DC maturation and function, and it acted as an adjuvant in promoting Ag-specific immune responses in mice. Thus, pullulan could be a new and useful adjuvant for use in therapeutic cancer vaccines.

Abstract
Despite the advent of many therapeutic agents, such as bortezomib and lenalidomide that have significantly improved the overall survival, multiple myeloma remains an incurable disease. Failure to cure is multifactorial and can be attributed to the underlying genetic heterogeneity of the cancer and to the surrounding micro-environment. Understanding the mutual interaction between myeloma cells and micro-environment may lead to the development of novel treatment strategies able to eradicate this disease. In this review we discuss the principal molecules involved in the micro-environment network in multiple myeloma and the currently available therapies targeting them.

Abstract
Lenalidomide (LEN) has been used as an immunomodulatory drug with direct and indirect anti-tumor effects. In this study, we evaluated the effect of LEN on the differentiation, maturation, and function of dendritic cells (DCs) in patients with multiple myeloma in vitro. Various doses of LEN were added after the monocytes had differentiated into immature DCs and were activated into mature DCs. LEN (5 μg/mL) was the optimal concentration to promote differentiation and maturation of DCs. Immature DCs treated with LEN exhibited enhanced endocytic capacity. Mature DCs treated with LEN produced higher levels of interleukin-12p70, possessed stronger allogeneic T-cell stimulation capacity, reduced the number of suppressor cells, and generated antigen-specific cytotoxic T lymphocytes more potently compared with control DCs. These results suggest that LEN enhanced the function of DCs generated from patients with multiple myeloma by stimulating the capacity of allogeneic T cells, inhibiting the generation of immunosuppressive cells, inducing naïve T cells toward Th1 polarization, and generating potent myeloma-specific cytotoxic T lymphocytes.

Efficacy of host-dendritic cell vaccinations with or without minor histocompatibility antigen loading, combined with donor lymphocyte infusion in multiple myeloma patients. Bone Marrow Transplant 2016; 52:228-237.

Abstract
Donor lymphocyte infusions (DLI) can induce durable remissions in multiple myeloma (MM) patients, but this occurs rather infrequently. As the graft-versus-tumor (GvT) effect of DLI depends on the presence of host-dendritic cells (DCs), we tested in a phase I/II trial whether the efficacy of DLI could be improved by simultaneous vaccination with host-DCs. We also analyzed the possibility of further improving the GvT effect by loading the DCs with peptides of mismatched hematopoietic cell-specific minor histocompatibility antigens (mHags). Fifteen MM patients not responding to a first DLI were included. Eleven patients could be treated with a second equivalent dose DLI combined with DC vaccinations, generated from host monocytes (moDC). For four patients, the DC products did not meet the quality criteria. In four of the treated patients the DCs were loaded with host mHag peptides. Toxicity was limited and no acute GvHD occurred. Most patients developed objective anti-host T-cell responses and in one patient a distinct mHag-specific T-cell response accompanied a temporary clinical response. These findings confirm that DLI combined with host-DC vaccination, either unloaded or loaded with mHag peptides, is feasible, safe and capable of inducing host-specific T-cell responses. The limited clinical effects may be improved by developing more immunogenic DC products or by combining this therapy with immune potentiating modalities like checkpoint inhibitors.

Abstract
Background: Interleukin-10 (IL-10) is a inhibiting inflammatory cytokine that plays an important role in immune suppressive microenvironment in multiple myeloma (MM). Whether the level of serum IL-10 could predict treatment response and survival outcomes or not needs to be investigated in MM patients. Methods: The level of IL-10 in serum was measured using enzyme-linked immunosorbent assay in 188 patients with newly diagnosed MM. Results: The best cutoff value for IL-10 in predicting survival is 169.69 pg ml−1 with an area under the curve (AUC) value of 0.747 (P<0.001). In all, 92 patients (48.9%) were classified as high-IL-10 group (>169.96 pg ml−1) and 96 patients (51.1%) as low-IL-10 group (⩽169.96 pg ml−1). The overall response rate (ORR) was 79.2% in low-IL-10 group, significantly higher than that in high-IL-10 group (53.3%, P<0.001). Patients in low-IL-10 group had significantly better survival compared with those in high-IL-10 group (3-year PFS rate: 69.3% vs 13.3%, P<0.001; 3-year OS rate: 93.6% vs 51.9%, P<0.001). Multivariate analysis revealed that serum IL-10 level >169.96 pg ml−1 at diagnosis and certain cytogenetic abnormalities were two adverse factors for PFS and OS. Conclusions: Our data suggest that serum IL-10 at diagnosis is a novel, powerful predictor of prognosis for MM.

Abstract
BACKGROUND AIMS It is important to improve the migratory ability of dendritic cells (DCs) and to increase DC potency for successful DC-based cancer immunotherapy. The intracellular Ca(2+) signaling pathway has an important role on the regulation of DC migration. Our preliminary studies revealed that sarco/endoplasmic reticulum Ca(2+) transport ATPase 2 (SERCA2) expression was inversely related to DC migratory capacity, and the expression level of p-cofilin and SERCA2 on mature DCs showed a counter-trend. METHODS We selected the appropriate six maturation cocktails on the basis of the expression levels of SERCA2 and p-cofilin and investigated the functional characteristics and migratory capacity of mature DCs. Among the these six maturation cocktails, DCIFN-γ/IL-1β/Poly-I:C showed potent type 1 immune response with interleukin (IL)-12p70 production and strong Th1-polarization, and this DC elicited strong antigen-specific cytotoxic T-lymphocyte responses. RESULTS Interestingly, DCIFN-γ/IL-1β/Poly-I:C showed lower expression of SERCA2 and higher expression of p-cofilin compared with those matured with the use of other cocktails. In vitro migration assay showed that DCs matured with the use of this maturation cocktail had significantly increased migratory ability compared with αDC1s and other DCs. CONCLUSIONS Interferon-γ, IL-1β and Poly-I:C maturation cocktail may be used in the field of cancer immunotherapy to generate potent immune-stimulatory DCs with improved type 1 immune response and migration capacity.

Dendritic cells accumulate in the bone marrow of myeloma patients where they protect tumor plasma cells from CD8+ T-cell killing. Blood 2015; 126:1443-51.

Abstract
Many researchers have speculated that the clinical progression from monoclonal gammopathy of undetermined significance (MGUS) to multiple myeloma (MM) is driven by defects in dendritic cell (DC) function. However, evidence supporting this assumption is controversial, and no mechanism for the putative DC dysfunction has been demonstrated thus far. We studied DC subsets from the bone marrow of MM patients compared with those of MGUS patients and control subjects. We found that myeloid DCs (mDCs) and plasmacytoid DCs (pDCs) accumulate in the bone marrow during the MGUS-to-MM progression. After engulfment of apoptotic tumor plasma cells via CD91, bone marrow mDCs and pDCs mature and are able to activate tumor-specific CD8(+) T cells. However, by interacting directly with CD28 on live (nonapoptotic) tumor plasma cells, bone marrow mDCs downregulate the expression of proteasome subunits in these cells, thus enabling their evasion from human leukocyte antigen (HLA) class I-restricted CD8(+) T-cell killing. These results suggest that DCs play a dual, but opposing, role in MM: for one, DCs activate CD8(+) T cells against tumor plasma cells and, for the other, DCs protect tumor plasma cells from CD8(+) T-cell killing. This information should be taken into account in designing immunotherapy approaches to enhance immune surveillance in MGUS and to break down immune tolerance in MM.

Abstract
Nanoparticles in the field of dendritic cell (DC) research are emerging as a promising method of enhancing the efficacy of cancer immunotherapy. We investigated the effect of branched polyethylenimine-superparamagnetic iron oxide nanoparticles (bPEI-SPIONs) on tumor cells loaded onto DCs. The tumor antigens were prepared as follows: (1) apoptotic U266 cells with ultraviolet B (UVB) irradiation followed by a 2 h incubation in the absence (2 h postirradiated cells) or (2) presence of bPEI-SPIONs (bPEI-SPION 2 h postirradiated cells) and (3) apoptotic U266 cells with UVB irradiation followed by an overnight 16 h incubation (16 h postirradiated cells). bPEI-SPIONs render U266 cells sensitive to UVB irradiation through reactive oxygen species production to accelerate apoptotic death. The 2 h postirradiated cells and bPEI-SPION 2 h postirradiated cells released immunogenic proteins, including Hsp70, Hsp90, and HMGB1. The DCs loaded with bPEI-SPION 2 h postirradiated cells showed the highest IL-12p70 production and Th1 polarization compared with other DCs. These results suggest that bPEI-SPIONs are a promising method of enhancing the immunogenicity of tumor cells and promoting Th1 polarization of DCs loaded with these tumor cells.

Abstract
Tumor immunotherapy holds great promise in controlling multiple myeloma (MM) and may provide an alternative treatment modality to conventional chemotherapy for MM patients. For this reason, a major area of investigation is the development of cancer vaccines to generate myeloma-specific immunity. Several antigens that are able to induce specific T-cell responses are involved in different critical mechanisms for cell differentiation, inhibition of apoptosis, demethylation and proliferation. Strategies under development include infusion of vaccine-primed and ex vivo expanded/costimulated autologous T cells after high-dose melphalan, genetic engineering of autologous T cells with receptors for myeloma-specific epitopes, administration of dendritic cell/plasma cell fusions and administration expanded marrow-infiltrating lymphocytes. In addition, novel immunomodulatory drugs may synergize with immunotherapies. The task ahead is to evaluate these approaches in appropriate clinical settings, and to couple them with strategies to overcome mechanisms of immunoparesis as a means to induce more robust clinically significant immune responses.

Abstract
Despite high-dose chemotherapy followed by autologs stem-cell transplantation as well as novel therapeutic agents, multiple myeloma (MM) remains incurable. Following the general trend towards personalized therapy, targeted immunotherapy as a new approach in the therapy of MM has emerged. Better progression-free survival and overall survival after tandem autologs/allogeneic stem cell transplantation suggest a graft versus myeloma effect strongly supporting the usefulness of immunological therapies for MM patients. How to induce a powerful antimyeloma effect is the key issue in this field. Pivotal is the definition of appropriate tumor antigen targets and effective methods for expansion of T cells with clinical activity. Besides a comprehensive list of tumor antigens for T cell-based approaches, eight promising antigens, CS1, Dickkopf-1, HM1.24, Human telomerase reverse transcriptase, MAGE-A3, New York Esophageal-1, Receptor of hyaluronic acid mediated motility and Wilms' tumor gene 1, are described in detail to provide a background for potential clinical use. Results from both closed and on-going clinical trials are summarized in this review. On the basis of the preclinical and clinical data, we elaborate on three encouraging therapeutic options, vaccine-enhanced donor lymphocyte infusion, chimeric antigen receptors-transfected T cells as well as vaccines with multiple antigen peptides, to pave the way towards clinically significant immune responses against MM.

Abstract
BACKGROUND In addition to its direct cytotoxic effects, radiation therapy renders tumor cells more susceptible to T cell-mediated cytotoxicity by modulating cell surface molecules involved in antigen presentation. The purpose of the present study was to determine the benefit of combined 89Sr radiation and dendritic cell (DC) vaccine therapy in bone metastasis patients. METHODS Patients were treated with intravenous 89Sr at a dose of 40 μCi/kg of body weight on the first day after the peripheral blood mononuclear cell collection. Seven days later, patients received DCs once a week for 6 weeks. The first three vaccines were administered by intravenous infusion, and the last three vaccines were administered by 24-point intradermal injection. Clinical response was evaluated by the number of bone metastatic foci demonstrated on bone scintigraphy; cell-mediated cytotoxicity response was evaluated by delayed-type hypersensitivity (DTH) reaction. All treatment-related toxicities including vaccine-induced fever and 89Sr-associated hematological toxicity were carefully monitored. RESULTS Twenty-six patients with histologically diagnosed with primary cancers and multiple bone metastases demonstrated on bone scintigraphy were studied. The overall survival rate was 58.3%. The total positive DTH rate was 50%. The efficiency rate for pain relief was 60% (6/10), for quantity of life was 80%, and for clinic responses was 90%. Out of 10 cases, the Grade 1 or 2 of hematological depression in 4, erythema in 1, and fever in 7 were observed. CONCLUSIONS The study has important implications for that combined 89Sr radiation, and DC vaccine therapy can benefit cancer patients with bone metastasis.

Abstract
Signal transducer and activator of transcription 3 (STAT3) is highly activated in multiple myeloma. Activated STAT3 promotes survival and proliferation of cancer cells, suppresses Th1 immune response, and induces dysfunction of immune cells. We investigated whether pretreating myeloma cells with a phosphor (p)-STAT3 inhibitor (JSI-124) and/or bortezomib before loading into dendritic cells (DCs) can affect DC function. The combination treatment with JSI-124 and bortezomib resulted in the highest expression of heat shock protein (HSP) 90 and the lowest expression of p-STAT3 in dying myeloma cells. DCs loaded with dying myeloma cells treated by JSI-124 and bortezomib produced the least amount of p-STAT3 compared to other treatments. The DCs were recovered from abnormal cytokine secretions of interleukin (IL)-10, IL-6, and IL-23 without any effect on production of IL-12p70. DCs loaded with JSI-124 and bortezomib treated, dying myeloma cells most potently generated myeloma-specific cytotoxic T lymphocytes (CTLs). The data suggest that pretreatment of myeloma cells with JSI-124 and bortezomib can recover DC function through the up-regulation of HSP90 and the down-regulation of p-STAT3 and inhibitory cytokines, and that these DCs can potently generate myeloma-specific CTLs.

Abstract
INTRODUCTION Multiple myeloma (MM) is characterized by generalized immune suppression and increased susceptibility to infections and secondary malignancies. Malignant plasma cells (PCs) modulate the bone marrow microenvironment to favor their own survival and proliferation. These events lead to a severe deregulation of immune effectors. Extensive studies have been conducted to unveil the mechanisms through which MM cells negatively modulate immunity and to develop therapeutical approaches for restoring an efficient anti-MM immune response. AREAS COVERED This review article covers both the immunosuppressive effects exerted by MM and the immunomodulatory potential of novel anti-MM agents. A brief overview on the most promising immunotherapeutic approaches in the field is also provided. EXPERT OPINION MM leads to a progressive impairment of the immune system. Different approaches have been evaluated or are currently under investigation to boost a specific anti-MM immune response. The discovery that anti-MM agents like bortezomib also retain immunomodulatory properties provides evidence to support the development of combined treatment modalities. In the next future, immunotherapy will be likely included in selective treatments in early stages or in the post-transplantation setting with non toxic modalities that control or clear the neoplastic clone.

Abstract
Recently gained insight into the role of dendritic cells (DCs) as APCs has attracted the attention of many researchers who hope to use them as a tool in immunotherapy for the induction of tumor-specific immunity in cancer settings. Despite high expectations, in multiple myeloma patients the results of DC-based vaccines in terms of clinical response have been disappointing. The findings of Zahradova et al. in a Phase II clinical trial with multiple myeloma patients corroborated these results. Although no clinical responses were observed, the investigators induced immunity after vaccination with Id-protein-loaded DC vaccine in some patients. These immunological results showed a trend towards a longer duration of stable disease in those patients that received the vaccination. Moreover, this study showed that Id-protein-loaded DC vaccines are safe and nontoxic and that they are able to induce immunity in some patients. Therefore, standardization of vaccination protocols appears to be the key to achieving a better clinical outcome.

Abstract
Adenovirus has been extensively exploited as a vector platform for delivering vaccines. However, preexisting antiadenovirus immunity is the major stumbling block for application of adenovirus-vectored vaccines. In this study, we found that freshly isolated peripheral blood mononuclear cells (PBMCs), mostly CD14(+) cells, from adenovirus serotype 5 (Ad5)-seropositive primates (humans and rhesus macaques) can be efficiently infected with Ad5 in vitro. On the basis of this observation, a novel strategy based on adenoviral vector-infected PBMC (AVIP) immunization was explored to circumvent antivector immunity. Autologous infusion of Ad5-SIVgag-infected PBMCs elicited a strong Gag-specific cellular immune response but induced weaker Ad5-neutralizing antibody (NAb) in Ad5-seronegative macaques than in macaques intramuscularly injected with Ad5-SIVgag. Moreover, Ad5-seropositive macaques receiving multiple AVIP immunizations with Ad5-SIVenv, Ad5-SIVgag, and Ad5-SIVpol vaccines elicited escalated Env-, Gag-, and Pol-specific immune responses after each immunization that were significantly greater than those in macaques intramuscularly injected with these Ad5-SIV vaccines. After challenged intravenously with a highly pathogenic SIVmac239 virus, macaques receiving AVIP immunization demonstrated a significant reduction in viral load at both the peak time and set-point period compared with macaques without Ad5-SIV vaccines. Our study warranted further research and development of the AVIP immunization as a platform for repeated applications of adenovirus-vectored vaccines.
