1Immunotherapy for colorectal cancer显示文摘The incidence of colorectal cancer(CRC)is on the rise,and the prognosis for patients with recurrent or metastatic disease is extremely poor.Although chemotherapy and radiation therapy can improve survival rates,it is imperative to integrate alternative strategies such as immunotherapy to improve outcomes for patients with advanced CRC.In this review,we will discuss the effect of immunotherapy for inducing cytotoxic T lymphocytes and the major immunotherapeutic approaches for CRC that are currently in clinical trials,including peptide vaccines,dendritic cell-based cancer vaccines,whole tumor cell vaccines,viral vector-based cancer vaccines,adoptive cell transfer therapy,antibody-based cancer immunotherapy,and cytokine therapy.The possibility of combination therapies will also be discussed along with the challenges presented by tumor escape mechanisms.Shigeo Koido Toshifumi Ohkusa Sadamu Homma Yoshihisa Namiki Kazuki Takakura Keisuke Saito Zensho Ito Hiroko Kobayashi Mikio Kajihara Kan Uchiyama Seiji Arihiro Hiroshi Arakawa Masato Okamoto Jianlin Gong Hisao Tajiri 2013World Journal of Gastroenterology2013,19,46:11

4Dendritic cell-based vaccine for pancreatic cancer in Japan显示文摘'Vaccell' is a dendritic cell(DC)-based cancer vaccine which has been established in Japan. The DCs play central roles in deciding the direction of host immune reactions as well as antigen presentation. We have demonstrated that DCs treated with a streptococcal immune adjuvant OK-432, produce interleukin-12, induce Th1-dominant state, and elicit anti-tumor effects, more powerful than those treated with the known DCmaturating factors. We therefore decided to mature DCs by the OK-432 for making an effective DC vaccine, Vaccell. The 255 patients with inoperable pancreatic cancer who received standard chemotherapy combined with DC vaccines, were analyzed retrospectively. Survival time of the patients with positive delayed type hypersensitivity(DTH) skin reaction was significantly prolonged as compared with that of the patients with negative DTH. The findings strongly suggest that there may be 'Responders' for the DC vaccine in advanced pancreatic cancer patients. We next conducted a smallscale prospective clinical study. In this trial, we pulsed HLA class Ⅱ-restricted WT1 peptide(WT1-Ⅱ) in addition to HLA class Ⅰ-restricted peptide(WT1-Ⅰ) into the DCs. Survival of the patients received WT1-Ⅰ and-Ⅱ pulsed DC vaccine was significantly extended as compared to that of the patients received DCs pulsed with WT1-Ⅰ or WT1-Ⅱ alone. Furthermore, WT1-specific DTH positive patients showed significantly improved the overall survival as well as progressionfree survival as compared to the DTH negative patients. The activation of antigen-specific immune responses by DC vaccine in combination with standard chemotherapy may be associated with a good clinical outcome in advanced pancreatic cancer. We are now planning a pivotal study of the Vaccell in appropriate protocols in Japan.Masato Okamoto Masanori Kobayashi Yoshikazu Yonemitsu Shigeo Koido Sadamu Homma 2016World Journal of Gastrointestinal Pharmacology and Therapeutics2016,7,1:2
5Production of corticotropin-releasing factor and urocortin from human monocyte-derived dendritic cells is stimulated by commensal bacteria in intestine显示文摘AIM:To examine whether commensal bacteria are a contributing cause of stress-related mucosal inflammation.METHODS:Human peripheral blood monocyte-deriveddendritic cells(MoDCs)were stimulated by commensal bacterial strains,including Escherichia coli,Clostridium clostridioforme,Bacteroides vulgatus(B.vulgatus),Fusobacterium varium(F.varium),and Lactobacillus delbrueckii subsp.bulgaricus.After incubation,corticotropin-releasing factor(CRF)and urocortin 1(UCN1)mRNA in the cells was examined by real-time reverse transcription polymerase chain reaction.Supernatants from the cells were tested for CRF and UCN1 using an enzyme-linked immunosorbent assay.RESULTS:Both CRF and UCN1 were significantly augmented by B.vulgatus and F.varium at both the mRNA and protein levels.In particular,B.vulgatus stimulated human MoDCs,resulting in extremely high levels of CRF and UCN1.CONCLUSION:Stimulation of MoDCs by B.vulgatus and F.varium may be associated with CRF/UCN1-related intestinal disorders,such as irritable bowel syndrome and inflammatory bowel disease.Shigeo Koido Toshifumi Ohkusa Shin Kan Kazuki Takakura Keisuke Saito Hideo Komita Zensho Ito Hiroko Kobayashi Shinichiro Takami Kan Uchiyama Hiroshi Arakawa Masaki Ito Masato Okamoto Mikio Kajihara Sadamu Homma Hisao Tajiri 2014World Journal of Gastroenterology2014,20,39:2
