Special Issue Information

Dear Colleagues,

In the past few years, the concept of immunogenic cell death (ICD) has emerged, which underlines the important role of the immune system in the efficacy of cancer therapy. Indeed, several studies have demonstrated that cancer cell lines treated ex vivo with anthracyclines, oxaliplatin, photodynamic therapy (PDT) or γ-irradiation and are then implanted subcutaneously into syngeneic immuno-competent mice function as a cancer vaccine in the absence of any adjuvants or immunostimulatory substances by protecting mice against subsequent rechallenges with live cancer cell lines.

Immunogenic cell death (ICD) is a form of regulated cell death accompanied by the exposure, active secretion, or passive release of numerous DAMPs (damage-associated molecular patterns) that can function as either adjuvants or danger signals in the activation of both innate and adaptive immune responses. ICD can be induced by different stressors, including (1) intracellular pathogens; (2) certain chemotherapeutic drugs such as anthracyclines, DNA-damaging agents, and proteasomal inhibitors; (3) oncolytic viruses; (4) targeted anticancer agents such as the tyrosine kinase inhibitor crizotinib, the epidermal growth factor receptor-specific monoclonal antibody cetuximab, and poly-ADP-ribose  polymerase (PARP) inhibitors; (5) physicochemical therapies and photodynamic therapy; and (6) radiotherapy. So, there is evidence that treatment-driven ICD can elicit anticancer immune responses that reinforce the therapeutic effects of conventional anti-cancer chemotherapies and radiotherapy.

This Special issue aims at expanding the current knowledge on ICD-related processes and molecules, on ICD inducers, and on the underlying mechanisms of signaling mediated by DAMPs in order to improve cancer therapies in a personalized, biomarker-driven manner. Experimental studies using in vitro and in vivo models, review articles, and clinical studies are all also welcome for consideration.

Immunogenic cell death (ICD) is a type of cell death capable of stimulating immunity against cancer through danger signals that lead to an adaptive immune response. Silver nanoparticles (AgNPs) have been shown to have a cytotoxic effect on cancer cells; however, their mechanism of action is not fully understood. The present study synthesized, characterized, and evaluated the cytotoxic effect of beta-D-glucose-reduced AgNPs (AgNPs-G) against breast cancer (BC) cells in vitro; and assess the immunogenicity of cell death in vitro and in vivo. The results showed that AgNPs-G induce cell death in a dose-dependent manner on BC cell lines. In addition, AgNPs show antiproliferative effects by interfering with the cell cycle. Regarding the detection of damage-associated molecular patterns (DAMPs), it was found that treatment with AgNPs-G induces calreticulin exposure and the release of HSP70, HSP90, HMGB1, and ATP. In vivo, prophylactic vaccination did not prevent tumor establishment; however, tumor weight was significantly lower in AgNPs-G vaccinated mice, while the survival rate increased. In conclusion, we have developed a new method for the synthesis of AgNPs-G, with in vitro antitumor cytotoxic activity on BC cells, accompanied by the release of DAMPs. In vivo, immunization with AgNPs-G failed to induce a complete immune response in mice. Consequently, additional studies are needed to elucidate the mechanism of cell death that leads to the design of strategies and combinations with clinical efficacy. Full article

Alterations in cellular signaling, chronic inflammation, and tissue remodeling contribute to hepatocellular carcinoma (HCC) development. The release of damage-associated molecular patterns (DAMPs) upon tissue injury and the ensuing sterile inflammation have also been attributed a role in HCC pathogenesis. Cargoes of extracellular vesicles (EVs) and/or EVs themselves have been listed among circulating DAMPs but only partially investigated in HCC. Mitochondria-derived vesicles (MDVs), a subpopulation of EVs, are another missing link in the comprehension of the molecular mechanisms underlying the onset and progression of HCC biology. EVs have been involved in HCC growth, dissemination, angiogenesis, and immunosurveillance escape. The contribution of MDVs to these processes is presently unclear. Pyroptosis triggers systemic inflammation through caspase-dependent apoptotic cell death and is implicated in tumor immunity. The analysis of this process, together with MDV characterization, may help capture the relationship among HCC development, mitochondrial quality control, and inflammation. The combination of immune checkpoint inhibitors (i.e., atezolizumab and bevacizumab) has been approved as a synergistic first-line systemic treatment for unresectable or advanced HCC. The lack of biomarkers that may allow prediction of treatment response and, therefore, patient selection, is a major unmet need. Herein, we overview the molecular mechanisms linking mitochondrial dysfunction, inflammation, and pyroptosis, and discuss how immunotherapy targets, at least partly, these routes. Full article

Ionizing radiation (IR) is used to treat 50% of cancers. While the cytotoxic effects related to DNA damage with IR have been known since the early 20th century, the role of the immune system in the treatment response is still yet to be fully determined. IR can induce immunogenic cell death (ICD), which activates innate and adaptive immunity against the cancer. It has also been widely reported that an intact immune system is essential to IR efficacy. However, this response is typically transient, and wound healing processes also become upregulated, dampening early immunological efforts to overcome the disease. This immune suppression involves many complex cellular and molecular mechanisms that ultimately result in the generation of radioresistance in many cases. Understanding the mechanisms behind these responses is challenging as the effects are extensive and often occur simultaneously within the tumor. Here, we describe the effects of IR on the immune landscape of tumors. ICD, along with myeloid and lymphoid responses to IR, are discussed, with the hope of shedding light on the complex immune stimulatory and immunosuppressive responses involved with this cornerstone cancer treatment. Leveraging these immunological effects can provide a platform for improving immunotherapy efficacy in the future. Full article
