Abstract
Objective This study aims to prepare candidate vaccines for cervical cancer immunotherapy by inserting the fused genes of human papillomavirus (HPV)16/18/58 mE6E7 lacking transforming activity into an adenovirus vector and to verify its efficiency in model mice with tumor expressing the associated HPV genes. Methods The E6/E7 genes of HPV16/18/58 were point-mutated to abolish their transforming activity, and adenovirus (AD)-HPV16/18/58 mE6E7 adenovirus vaccine was constructed. The immune effect of the adenovirus vaccine against HPV16/18/58-type tumors was analyzed by tumor morphology, enzyme linked immunosorbent assay, enzyme-linked immunospot and specific cytotoxic T lymphocyte (CTL) and T lymphocyte subsets. Results The HPV16/18/58 mE6E7 plasmid containing point mutations was verified by quantitative real-time polymerase chain reaction (qRT-PCR), enzyme digestion and electrophoresis, and gene sequencing. qRT-PCR and Western blots verified that AD-HPV16/18/58 mE6E7 could express the HPV16 mE6E7, HPV18 mE6E7 and HPV58 mE6E7 fusion genes and proteins in cells. The results of animal experiments were as follows: In the vaccine group, the tumors formed later, the incubation period was longer, the growth was slower, growth was inhibited, and the survival period was significantly prolonged. The immunological results all showed that the vaccine could induce effective humoral and cellular immunity in mice with three types of tumors, compared with the phosphate buffered saline (PBS) group and the adenovirus-negative control (AD-NC) group, the differences were statistically significant (P < 0.05). Conclusion We successfully constructed the HPV16/18/58 trivalent therapeutic adenovirus vaccine AD-HPV16/18/58 mE6E7. The AD-HPV16/18/58 mE6E7 adenovirus vaccine can protect immunized mice to a certain extent from TC-1, U14/LV-HPV18 E6E7 and U14/LV-HPV58 E6E7 cells, which contain HPV16, 18 and 58 E6 and/or E7 genes, respectively.

[PMID: 31448426 DOI: 10.1111/sji.12819] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2019] [Revised: 07/23/2019] [Accepted: 08/20/2019] [Indexed: 12/18/2022]
Abstract
Our aim was to evaluate the association of genetic polymorphisms of immunoregulatory molecules with susceptibility to hepatocellular carcinoma (HCC). The polymorphisms in CTLA-4 (-318 T/C, CT60 G/A), TNF (-238 G/A, -308 G/A) and IL10 (-592 C/A, -819 C/T) were genotyped by PCR and DNA sequencing. The functional relevance of the polymorphisms was examined by ELISAs, in vitro lymphocyte proliferation assay and cytotoxic assay. The CTLA-4 -318 TC/TT, CTLA-4 CT60 GG, IL10 -592 CA and -819 CT/TT variants, CTLA-4 -318 T and IL 10 -819 T alleles were positively associated with HCC risk (P < .05). While TNF -238 AA variant, TNF -238 A allele were associated with decreased risk of HCC (P < .05). Furthermore, combinations of CTLA-4 -318 TC/TT and TNF -238 GG/GA; CTLA-4 -318 TC/TT and IL 10 -819 CC; CTLA-4 -318 CC and IL 10 -819 CT/TT in patients with HCC were statistically significant (P < .05). Peripheral blood mononuclear cells (PBMCs) carrying -318 TC/TT genotypes exhibited significantly lower proliferation rates, decreased IL-2, IL-4 levels, fewer cytolytic activities and elevated TGF-β levels. For IL 10 -819 C/T, the CC genotype was significantly associated with higher proliferation rate, decreased TGF-β, IL-10 levels and higher cytolytic activities (P < .05). For TNF -238 G/A, the AA genotype only had association with serum IL-2, IL-4 (P < .05). In addition, we also found that CTLA-4 -318 T/C, IL-10 -819 T/C variants, combinations of CTLA-4 -318 CC with IL 10 -819 CT or TT, CTLA-4 -318 TC or TT with IL 10 -819 CT or TT were associated with the severity of HCC. These findings suggest that CTLA-4 -318 TC/TT and IL 10 -819 CT/TT could promote the pathogenesis of HCC, which might be related with down-regulation of Th1/Th2-type cytokines and/or up-regulation of Th3-type cytokines.

Abstract
The development of highly sensitive HPV-genotyping tests has opened the possibility of treating HPV-infected women before high-grade lesions appear. The lack of efficient intervention for persistent high-risk HPV infection necessitates the need for development of novel therapeutic strategy. Here we demonstrate that REBACIN®, a proprietary antiviral biologics, has shown potent efficacy in the clearance of persistent HPV infections. Two independent parallel clinical studies were investigated, which a total of 199 patients were enrolled and randomly divided into a REBACIN®-test group and a control group without treatment. The viral clearance rates for the REBACIN® groups were 61.5% (24/39) and 62.5% (35/56), respectively, for the two independent parallel studies. In contrast, the nontreatment groups showed self-clearance rates at 20.0% (8/40) and 12.5% (8/64). We further found that REBACIN® was able to significantly repress the expression of HPV E6 and E7 oncogenes in TC-1 and Hela cells. The two viral genes are well known for the development of high-grade premalignancy lesion and cervical cancer. In a mouse model, REBACIN® was indicated to notably suppress E6/E7-induced tumor growth, suggesting E6 and E7 oncogenes as a potential target of REBACIN®. Taken together, our studies shed light into the development of a novel noninvasive therapeutic intervention for clearance of persistent HPV infection with significant efficacy.

Abstract
Human papillomavirus (HPV) is associated with the etiology of cervical carcinoma, head and neck squamous cell carcinoma, and several other cancer types. Vaccines directed against HPV virus-like particles and coat proteins have been extremely successful in the prevention of cervical cancer through the activation of host HPV-specific antibody responses; however, HPV-associated cancers remain a major public health problem. The development of a therapeutic vaccine will require the generation of T-cell responses directed against early HPV proteins (E6/E7) expressed in HPV-infected tumor cells. Clinical studies using various vaccine platforms have demonstrated that both HPV-specific human T cells can be generated and patient benefit can be achieved. However, no HPV therapeutic vaccine has been approved by the Food and Drug Administration to date. One method of enhancing the potential efficacy of a therapeutic vaccine is the generation of agonist epitopes. We report the first description of enhancer cytotoxic T lymphocyte agonist epitopes for HPV E6 and E7. While the in silico algorithm revealed six epitopes with potentially improved binding to human leukocyte antigen-A2 allele (HLA-A2)-Class I, 5/6 demonstrated enhanced binding to HLA-Class I in cell-based assays and only 3/6 had a greater ability to activate HPV-specific T cells which could lyse tumor cells expressing native HPV, compared to their native epitope counterparts. These agonist epitopes have potential for use in a range of HPV therapeutic vaccine platforms and for use in HPV-specific adoptive T- or natural killer-cell platforms.

Abstract
Increasing evidence has suggested that bispecific and multivalent antibodies which have more antigen binding sites will improve their immunogenicity. The bispecific anti-idiotype antibody vaccine G22-I50 was obtained through genetic engineering to enhance the immunogenicity of anti-idiotype antibody vaccines G22 and I50. G22-I50 vaccination could induce anti-tumor immunity in the Balb/c mouse model. The protective and therapeutic efficacy of G22-I50 was also evaluated using the hu-PBL-SCID mouse model injected three times with G22-I50, G22, or I50 mixed with Freund's adjuvant. Results demonstrated that the protective anti-tumor effect of G22-I50 could be relevant with the production of Ab3 antibody and activation of CD8(+) cytotoxic T-lymphocytes. In preventive and therapeutic experiments, G22-I50 could reduce tumor size and prolong the survival time of HNE2-bearing mice (p<0.05). Human CD8(+) T lymphocytes infiltrated the tumor sites, and high levels of human IFN-γ, TNF-α, and caspase-3 were also detected in the tumors from G22-I50-vaccinated and -treated mice. Therefore, the bispecific anti-idiotype antibody vaccine G22-I50 can induce strong humoral and cell-mediated immune responses. This vaccine can be potentially applied to prevent and treat nasopharyngeal carcinoma.

Abstract
AIM To evaluate the inhibitory effect of a recombinant human papillomavirus (HPV) fusion protein vaccine on oral squamous cell carcinoma (OSCC). MATERIALS AND METHODS An animal model of OSCC was established using human peripheral blood lymphocyte reconstituted nonobese diabetic/severe combined immunodeficiency mice. HPV vaccine was subcutaneously injected into mice after tumor establishment. Tumors and spleens were measured, weighed and stained with hematoxylin and eosin. Lymphocyte subpopulations and cytotoxicity were analyzed with flow cytometric and cytotoxic T lymphocyte assay. RESULTS The average weight and volume of tumors were significantly lower in the vaccine group than in the control group from day 27. Mice in both groups had high percentages of human CD3+ and CD3+CD8+ T lymphocytes. An elevated percentage of human CD3+CD16+56+ natural killer cells was found in the vaccine group. Moreover, vaccine increased the infiltration of human CD3 and UCHL-1+ cells in tumor tissues and enhanced cytotoxicity. CONCLUSIONS The HPV fusion protein vaccine induces tumor cell death, lymphocyte infiltration and therefore suppresses tumor growth and protects against OSCC.

Abstract
Esophageal squamous cell carcinoma (ESCC) is one of the common cancers with a poor prognosis. Incidences of human papillomavirus (HPV) infection range from 0 to 67% in different parts of the world. It has been frequently associated with high-risk HPV genotypes 16 and 18. The present study analyzes the prevalence of HPV infection in ESCC tumor and adjoining mucosa. Fresh tissue samples were obtained from ESCC tumor (group I) and adjoining mucosa (group II). Aliquots of DNA extracts were used. There were 23 patients with paired samples, 19 (83%) were male. HPV was positive in 20/23 (87%). Mean age of HPV positive in group I was 56.63 ± 6.96 and in group II 54.31 ± 7.13 years (P > 0.05). Majority had more than one viral type. HPV52 was the most common observed in 14 (61%) males and two (9%) females. Other common viruses were HPV55, 39, and 59. Smoking had a significant association with viral positivity. p63 and p16 oncoproteins correlated with degree of tumor differentiation but not with viral status. We documented high prevalence of high-risk HPV in ESCC. Our observations support the concept of persistent infection by an oncogenic HPV in cancer development. Our study highlights importance of documenting viral genotype in a defined geographic area.

Abstract
Patients with head and neck squamous cell carcinoma (HNSCC) are at considerable risk for death, with 5-year relative survival rates of approximately 60%. The profound multifaceted deficiencies in cell-mediated immunity that persist in most patients after treatment may be related to the high rates of treatment failure and second primary malignancies. Radiotherapy and chemoradiotherapy commonly have severe acute and long-term side effects on immune responses. The development of immunotherapies reflects growing awareness that certain immune system deficiencies specific to HNSCC and some other cancers may contribute to the poor long-term outcomes. Systemic cell-mediated immunotherapy is intended to activate the entire immune system and mount a systemic and/or locoregional antitumor response. The delivery of cytokines, either by single cytokines, for example, interleukin-2, interleukin-12, interferon-γ, interferon-α, or by a biologic mix of multiple cytokines, such as IRX-2, may result in tumor rejection and durable immune responses. Targeted immunotherapy makes use of monoclonal antibodies or vaccines. All immunotherapies for HNSCC except cetuximab remain investigational, but a number of agents whose efficacy and tolerability are promising have entered phase 2 or phase 3 development.

Abstract
Human papillomavirus (HPV)-induced lesions are distinct in that they have targetable foreign antigens, the expression of which is necessary to maintain the cancerous phenotype. Hence, they pose as a very attractive target for "proof of concept" studies in the development of therapeutic vaccines. This review will focus on the most recent clinical trials for the immunotherapy of mucosal and cutaneous HPV-induced lesions as well as emerging therapeutic strategies that have been tested in preclinical models for HPV-induced lesions. Progress in peptide-based vaccines, DNA-based vaccines, viral/bacterial vector-based vaccines, immune response modifiers, photodynamic therapy and T cell receptor based therapy for HPV will be discussed.
