Due to increasing drug resistance and vivax specific relapses, immunoprophylaxis signifies a key control strategy in efforts to eradicate malaria worldwide. By far, the circumsporozoite protein (CSP) based vaccines are being developed since the 1980’s. However, they have produced major limitations in eliciting partial immune responses towards the parasite. Nevertheless, the Long Synthetic Peptides (LSP’s) and Vivax Malarial Protein 001 (VMP001) have produced considerable amount of immune responses and are currently undergoing phase 1 clinical trials according to several studies. Recent developments of a Virus-like particle (VLP) was found to be an efficacious vaccine candidate against a human sporozoite challenge model. The VLP’s elicited high antibody titers that remained consistent for a number of days but eventually decreased. In addition, vaccine candidates such as the VLP’s are currently being used to target CSP based–antigens such as the Cell-Traversal Proteins to obstruct hepatocyte invasion by sporozoites. However, substantial humoral and cellular immune responses were not produced to alleviate this process. Further research of these vaccine candidates as well as to analyze its effects towards specific CSP based antigens would immensely contribute to move clinical development forward and to further identify mechanism of immunity.","PeriodicalId":93237,"journal":{"name":"Vaccination research : open journal","volume":"81 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79319083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Newcastle disease virus (NDV), which is pathogenic in birds, has beneficial clinical effects in cancer patients. NDV virotherapy is safe and elicits an antitumor response in patients affected by different types of cancers. The selective replication of NDV in tumor cells, the lack of genetic recombination, the lack of interaction with host cell DNA, and safety of NDV vaccination in cancer patients has resulted in NDV virotherapy to be accepted as a potentially attractive anticancer modality. However, more knowledge is needed to support the development of optimal NDV-based treatment modality for cancer. In this paper, the biological characteristics of NDV, the clinical effectiveness of NDV-based anticancer vaccination, immunobiology of NDV virotherapy in cancer patients, immune responses to NDV vaccines, and NDV-induced immunogenic cell death and apoptosis of cancer cells have been discussed in detail.","PeriodicalId":93237,"journal":{"name":"Vaccination research : open journal","volume":"38 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82029273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Introducing a self-adjuvanting moiety such as fluorinated lipids can overcome this problem. We have recently demonstrated that fluorinated lipids can induce humoral immune responses against associated peptide antigen; however, the ability of these amphiphilic lipids to elicit a desired cellular immune response to eradicate tumor cells has not been yet investigated. Methods: An in vivo assay was employed to evaluate the ability of fluorinated lipopeptides to eradicate tumor in mouse model. In this study, the double conjugation technique was used to synthesise fluorinated and non-fluorinated lipids conjugated to two cytotoxic T-lymphocyte (CTL) peptide epitopes derived from the E6 and E7 proteins of human papilloma virus (HPV). Results: Mice implanted with TC-1 tumor cells and immunised with fluorinated lipopeptides did not mount a strong cellular immune response, thus did not eradicate the tumors. In contrast, 60% of mice immunised with the non-fluorinated lipopeptide cleared the TC-1 tumor. Conclusion: This result indicated that fluorinated lipids lack of the ability to stimulate a strong cellular immunity despite their ability to elicit significant humoral immune responses.","PeriodicalId":93237,"journal":{"name":"Vaccination research : open journal","volume":"39 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82274912","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
