Abstract
With an increasing number of patients with degenerative hepatic diseases, such as liver fibrosis, and a limited supply of donor organs, there is an unmet need for therapies that can repair or regenerate damaged liver tissue. Treatment with macrophages that are capable of phagocytosis and anti-inflammatory activities such as secretion of matrix metalloproteinases (MMPs) provide an attractive cellular therapy approach. Human induced pluripotent stem cells (iPSCs) are capable of efficiently generating a large-scale, homogenous population of human macrophages using fully defined feeder- and serum-free differentiation protocol. Human iPSC-macrophages exhibit classical surface cell markers and phagocytic activity similar to peripheral blood-derived macrophages. Moreover, gene and cytokine expression analysis reveal that these macrophages can be efficiently polarized to pro-inflammatory M1 or anti-inflammatory M2 phenotypes in presence of LPS + IFN-γ and IL-4 + IL-13, respectively. M1 macrophages express high level of CD80, TNF-α, and IL-6 while M2 macrophages show elevated expression of CD206, CCL17, and CCL22. Here, we demonstrate that treatment of liver fibrosis with both human iPSC-derived macrophage populations and especially M2 subtype significantly reduces fibrogenic gene expression and disease associated histological markers including Sirius Red, αSMA and desmin in immunodeficient Rag2-/- γc-/- mice model, making this approach a promising cell-based avenue to ameliorate fibrosis.

Abstract
Mouse and human pluripotent stem cells have been widely used to study the development of the hematopoietic and immune systems. Although not all cells can be derived with the same efficiency, immune cells such as natural killer (NK) cells and macrophages can be easily produced from PSCs to enable development of new cell-based therapies. NK cells and macrophages are part of the innate immune system, the first line of defense against malignancies and infectious disease. Human embryonic stem cell (hESC)- and induced pluripotent stem cell (iPSC)-derived NK cells can be produced at a clinical scale suitable for translation into clinical trials. Additionally, PSCs can be genetically modified to produce hESC/iPSC-derived human NK cells with enhanced antitumor activity. These engineered NK cells can express a stabilized version of the high-affinity Fc receptor CD16, chimeric antigen receptors, or other strategies to enable more potent and targeted cellular immunotherapies. Moreover, macrophages can also be routinely and efficiently produced from hESCs and iPSCs as a tool to expand our knowledge of the basic biology of these cells. hESC- and iPSC-derived macrophages can also be employed as a novel approach for cancer immunotherapy, as well as a strategy to repair or regenerate diseased and damaged tissues and organs.

Abstract
It has been more than 10 years that the first prophylactic papillomavirus vaccine became available, although distribution has been mainly limited to the more affluent countries. The first two vaccines have been a great success, hundreds of millions of women and a much smaller number of men have been vaccinated ever since. In a few countries with high vaccination coverage, in particular Australia but also parts of Great Britain and others, clinical impact of vaccination programs is already visible and there are indications for herd immunity as well. Vaccine efficacy is higher than originally estimated and the vaccines have an excellent safety profile. Gardasil9 is a second generation HPV virus-like particle vaccine that was licensed in 2015 and there are more to come in the near future. Currently, burning questions in respect to HPV vaccination are the duration of protection - especially in regard to cross-protection - reduction of the three-dose regimen and its impact on cross-protection; and duration of response, as well as protection against oropharyngeal HPV infections. Furthermore, researchers are seeking to overcome limitations of the VLP vaccines, namely low thermal stability, cost, invasive administration, limited coverage of non-vaccine HPV types, and lack of therapeutic efficacy. In this review we summarize the current status of licensed VLP vaccines and address questions related to second and third generation HPV vaccines.

Abstract
Internal grafting of designed peptides to scaffold proteins is a valuable strategy for a variety of applications including recombinant peptide antigen construction. A peptide epitope from human papillomavirus (HPV) minor capsid protein L2 displayed on thioredoxin (Trx) has been validated preclinically as a broadly protective and low-cost alternative HPV vaccine. Focusing on thioredoxin from the hyperthermophilic archaebacterium Pyrococcus furiosus (PfTrx) as a scaffold, we have constructed a modified Pichia pastoris expression vector and used a PfTrx fusion derivative containing three tandemly repeated copies of a 19 amino acids peptide epitope from HPV-L2 for expression optimization and biochemical-immunological characterization of the Pichia-produced PfTrx-L2 antigen. We show that PfTrx-L2 is produced at high levels (up to 100 mg from a 100 ml starting culture using a multi-cycle induction protocol) and secreted into the culture medium as a highly enriched (>70% pure), non-glycosylated polypeptide that can be purified to homogeneity in a single step. Oxidation and aggregation state, thermal stability and immunogenicity of the endotoxin-free PfTrx-L2 antigen produced in P. pastoris were tested and found to be identical to those of the same antigen produced in Escherichia coli. Secretory production of endotoxin-free PfTrx-peptides in P. pastoris represents a cost- and time-effective alternative to E. coli production. Specifically designed for peptide antigens, the PfTrx-expression vector and conditions described herein are easily transferable to a variety of applications centred on the use of structurally constrained bioactive peptides as immune as well as target-specific binder reagents.

Abstract
We report here the development of multivalent T7 bacteriophage nanoparticles displaying an immunodominant H-2kd-restricted CTL epitope derived from the rat HER2/neu oncoprotein. The immunotherapeutic potential of the chimeric T7 nanoparticles as anti-cancer vaccine was investigated in BALB/c mice in an implantable breast tumor model. The results showed that T7 phage nanoparticles confer a high immunogenicity to the HER-2-derived minimal CTL epitope, as shown by inducing robust CTL responses. Furthermore, the chimeric nanoparticles protected mice against HER-2-positive tumor challenge in both prophylactic and therapeutic setting. In conclusion, these results suggest that CTL epitope-carrying T7 phage nanoparticles might be a promising approach for development of T cell epitope-based cancer vaccines.

Abstract
Considering the emergence of highly pathogenic influenza viruses and threat of worldwide pandemics, there is an urgent need to develop broadly-protective influenza vaccines. In this study, we demonstrate the potential of T7 bacteriophage-based nanoparticles with genetically fused ectodomain of influenza A virus M2 protein (T7-M2e) as a candidate universal flu vaccine. Immunization of mice with non-adjuvanted T7-M2e elicited M2e-specific serum antibody responses that were similar in magnitude to those elicited by M2e peptide administered in Freund’s adjuvant. Comparable IgG responses directed against T7 phage capsomers were induced following vaccination with wild type T7 or T7-M2e. T7-M2e immunization induced balanced amounts of IgG1 and IgG2a antibodies and these antibodies specifically recognized native M2 on the surface of influenza A virus-infected mammalian cells. The frequency of IFN-γ-secreting T cells induced by T7-M2e nanoparticles was comparable to those elicited by M2e peptide emulsified in Freund’s adjuvant. Emulsification of T7-M2e nanoparticles in Freund’s adjuvant, however, induced a significantly stronger T cell response. Furthermore, T7-M2e-immunized mice were protected against lethal challenge with an H1N1 or an H3N2 virus, implying the induction of hetero-subtypic immunity in our mouse model. T7-M2e-immunized mice displayed considerable weight loss and had significantly reduced viral load in their lungs compared to controls. We conclude that display of M2e on the surface of T7 phage nanoparticles offers an efficient and economical opportunity to induce cross-protective M2e-based immunity against influenza A.

Abstract
BACKGROUND Studies on efficacy of various vaccines that prevent or reduce the primary and recurrent HSV-1 infection have demonstrated the importance of cellular immunity for protection against the infection. We previously used DNA vaccination to induce cellular immunity against HSV-1 infection in mice. OBJECTIVE The aim of our study was to evaluate the effect of LIGHT; a member of TNF super family, on the kinetic of CTL response induced by HSV-1 glycoprotein B based DNA vaccine. METHODS Using a granzyme B ELISA for detection and analysis of CD8+ T cells, CTL activity was determined in the spleen of BALB/c mice at various time points after primary and booster dose of vaccination. The kinetics of CTL response to primary and secondary HSV-1 infection and DNA vaccination were compared to those induced by DNA vaccination in combination with LIGHT adjuvant in the present study. RESULTS In primary and secondary immunization, the CTL activity in the HSV injected group peaked 7 days and 12 hours post immunization, respectively. After 5 days, LIGHT could neither accelerate the CTL response compared to DNA vaccination alone nor could enhance the CTL activity in the primary and the first peak of memory response, the amount of granzyme B induced by the LIGHT containing vaccine was significantly higher than that induced by the vaccine without the adjuvant. CONCLUSION Although LIGHT enhances the cellular response in the booster dose of vaccination, it does not accelerate the CTL response.
