Novel therapeutic strategies and perspectives for metastatic pancreatic cancer: vaccine therapy is more than just a theory.

ABSTRACT: Pancreatic cancer is an aggressive and malignant tumor with an exceedingly high mortality rate. The quality of life and survival rates of pancreatic cancer patients with metastasis are poor compared with those without metastasis. Thus far, no effective treatment strategy has been established for metastatic pancreatic cancer patients. Therefore, an appropriate therapeutic method based on the elimination of metastatic pancreatic cancer is critical to improve patient outcome. Tumor-targeted vaccines have been widely discussed in recent studies and enabled important breakthroughs in the treatment of pancreatic cancer by preventing the escape of tumor cells from immune surveillance and activating the immune system to eliminate cancer cells. T cells can be activated by the stimulation of tumor-targeted vaccines, but to mount an effective immune response, both immune checkpoint inhibitors and positive costimulatory molecules are required. In this review, we discuss potential tumor-targeted vaccines that can target pancreatic cancer, elaborate the probably appropriate combination of vaccines therapy and evaluate the underlying benefits as well as obstacles in the current therapy for metastatic pancreatic cancer.

Project description:The molecular platforms of the innate immune system are essential to recognize pathologic external factors that are crucial to differentiate these danger signals from host motifs. A set of sensors recognizing pathologic factors is present and defined as a membrane-bound family of Toll-like receptors as well as the cytosolic ones including the family of nucleotide-binding domain leucine-rich repeat proteins. In this regard, the inflammasomes have been identified as an innate immune sensor toward pathologic external factors as well as endogenous damage-associated molecular pattern signals transducing from the above-mentioned receptors to gene expressions. Recent research has shown novel findings in inflammasome biology and genetics which lead to the alteration of diagnosis and management in autoinflammatory diseases as well as developing novel treatments, including the examples of nucleotide-binding domain leucine-rich repeat proteins-inflammasomes and pyrin-inflammasomes. The pyrin protein is encoded by the Mediterranean Fever gene on chromosome 16 that acts as a major regulatory component of the inflammasome, and is responsible for familial Mediterranean fever. We have recently examined the whole nucleotide sequence of the Mediterranean Fever gene in Japanese familial Mediterranean fever patients and revealed single nucleotide variants associated with the susceptibility of familial Mediterranean fever from a nation-wide survey by the next-generation sequencing. In a cytokine profile analysis of familial Mediterranean fever patients, we have found that interleukin-6 is considered to be one of the most crucial cytokines in familial Mediterranean fever attack since interleukin-6 had the best performance for distinguishing familial Mediterranean fever in attack from healthy controls or familial Mediterranean fever in remission, and in vitro interleukin-6 production is regulated by microRNAs-204-3p/phosphoinositide 3-kinase g pathway. Accordingly, we have been investigating the efficacy and safety of anti-human interleukin-6 receptor monoclonal antibody, tocilizumab, in patients with familial Mediterranean fever refractory or intolerant to colchicine through an investigator-initiated clinical trial supported by the Japan Agency for Medical Research and Development. Like interleukin-1b, interleukin-18 can be processed by caspase-1 and proteinase-3 to be activated within the inflammasomes. We have also found the importance of interleukin-18 in several autoinflammatory conditions. Recently, the concept of autoinflammation is widely distributed into many common diseases; thus, the attention to a wide spectrum of diseases MEFV gene deeply involved is required.
