Abstract
The immune system plays a crucial role in recognizing and eliminating pathogenic substances and malignant cells in the body. For cancer treatment, immunotherapy is becoming the standard treatment for many types of cancer and is often combined with chemotherapy. Although chemotherapeutic agents are often reported to have adverse effects, including immunosuppression, they can also play a positive role in immunotherapy by directly stimulating the immune system. This has been demonstrated in preclinical and clinical studies in the past decades. Chemotherapeutics can activate immune cells through different immune receptors and signaling pathways depending on their chemical structure and formulation. In this review, we summarize and discuss the direct immunoactivation effects of chemotherapeutics and possible mechanisms behind these effects. Finally, we prospect chemo-immunotherapeutic combinations for the more effective and safer treatment of cancer.

Abstract
Treatment of solid tumors by chemotherapy is usually failed in clinical because of its low effectiveness and side effects. Stimulation of immune system in vivo to fight cancer has been proved to be a pleasant complementary to systemic chemotherapy. Herein, we have developed a combination cancer therapy strategy by using polymer nanoparticles to deliver Gd-metallofullerenol and doxorubicin simultaneously. The Gd-metallofullerenol provoked the Th1 immune response by regulating the M1 macrophage polarization and the doxorubicin realized direct tumor cells killing by its cytotoxic effect. Also, the Gd-metallofullerenol as part of component in delivery system enhances the encapsulation efficiency of doxorubicin in polymer cargo for potential passive tumor target. The biocompatible and reliable method by combining nanoparticle-induced immune modulation and chemotherapy triggers systemic antitumor immune responses for the synergistic inhibition of tumor growth in vivo. The integration of Gd-metallofullerenol and doxorubicin with potentially complementary functions in one nanoplatform may provide new opportunities to improve cancer treatments.

Molecular characterization of calreticulin from Anopheles stephensi midgut cells and functional assay of the recombinant calreticulin with Plasmodium berghei ookinetes. Gene 2014; 550:245-52.

Abstract
Transmission blocking vaccines (TBVs) that target the antigens on the midgut epithelium of Anopheles mosquitoes are among the promising tools for the elimination of the malaria parasite. Characterization and analysis of effective antigens is the first step to design TBVs. Calreticulin (CRT), a lectin-like protein, from Anopheles albimanus midgut, has shown antigenic features, suggesting a promising and novel TBV target. CRT is a highly conserved protein with similar features in vertebrates and invertebrates including anopheline. We cloned the full-length crt gene from malaria vector, Anopheles stephensi (AsCrt) and explored the interaction of recombinant AsCrt protein, expressed in a prokaryotic system (pGEX-6p-1), with surface proteins of Plasmodium berghei ookinetes by immunofluorescence assay. The cellular localization of AsCrt was determined using the baculovirus expression system. Sequence analysis of the whole cDNA of AsCrt revealed that AsCrt contains an ORF of 1221 bp. The amino acid sequence of AsCrt protein obtained in this study showed 64% homology with similar protein in human. The AsCrt shares the most common features of CRTs from other species. This gene encodes a 406 amino-acid protein with a molecular mass of 46 kDa, which contains a predicted 16 amino-acid signal peptides, conserved cysteine residues, a proline-rich region, and highly acidic C-terminal domain with endoplasmic reticulum retrieval sequence HDEL. The production of GST-AsCrt recombinant protein was confirmed by Western blot analysis using an antibody against the GST protein. The FITC-labeled GST-AsCrt exhibited a significant interaction with P. berghei ookinete surface proteins. Purified recombinant GST-AsCrt, labeled with FITC, displayed specific binding to the surface of P. berghei ookinetes in comparison with control. Moreover, the expression of AsCrt in baculovirus expression system indicated that AsCrt was localized on the surface of Sf9 cells. Our results suggest that AsCrt could be utilized as a potential target for future studies in TBV area for malaria control.

Abstract
DNA-based vaccines hold promise to outperform conventional antigen-based vaccines by virtue of many unique features. However, DNA vaccines have thus far fallen short of expectations, due in part to poor targeting of professional antigen-presenting cells (APC) and low immunogenicity. In this study, we describe a new platform for effective and selective delivery of DNA to APCs in vivo that offers intrinsic immune-enhancing characteristics. This platform is based on conjugation of fifth generation polyamidoamine (G5-PAMAM) dendrimers, a DNA-loading surface, with MHC class II-targeting peptides that can selectively deliver these dendrimers to APCs under conditions that enhance their immune stimulatory potency. DNA conjugated with this platform efficiently transfected murine and human APCs in vitro. Subcutaneous administration of DNA-peptide-dendrimer complexes in vivo preferentially transfected dendritic cells (DC) in the draining lymph nodes, promoted generation of high affinity T cells, and elicited rejection of established tumors. Taken together, our findings show how PAMAM dendrimer complexes can be used for high transfection efficiency and effective targeting of APCs in vivo, conferring properties essential to generate effective DNA vaccines.

Abstract
It is now well established that most cervical cancers are causally associated with HPV infection. This realization has led to efforts to control HPV-associated malignancy through prevention or treatment of HPV infection. Currently, commercially available HPV vaccines are not designed to control established HPV infection and associated premalignant and malignant lesions. To treat and eradicate pre-existing HPV infections and associated lesions which remain prevalent in the U.S. and worldwide, effective therapeutic HPV vaccines are needed. DNA vaccination has emerged as a particularly promising form of therapeutic HPV vaccines due to its safety, stability and ability to induce antigen-specific immunity. This review focuses on improving the potency of therapeutic HPV vaccines through modification of dendritic cells (DCs) by [1] increasing the number of antigen-expressing/antigen-loaded DCs, [2] improving HPV antigen expression, processing and presentation in DCs, and [3] enhancing DC and T cell interaction. Continued improvement in therapeutic HPV DNA vaccines may ultimately lead to an effective DNA vaccine for the treatment of HPV-associated malignancies.

Abstract
The limited response rate of cancer patients treated with dendritic cell (DC)-based vaccines indicates that vast improvements remain necessary. In many murine tumour models it has been demonstrated that the use of innate triggers (e.g. TLR triggers) in the maturation of DC results in higher efficacy. However, as few of these innate triggers are generated clinical grade, there remains a great necessity to fill the gap between fundamental mouse studies and a clinical trial in humans. In the present study we used a TLR2/4-agonist (FMKp which is available clinical grade) in combination with IFN-gamma (FIcocktail) in the maturation of elutriated monocyte-derived DC and compared it with the most used DC in current clinical trials (TNF-alpha/PGE-2, i.e. TP-cocktail). In addition to the assessment of CD4+ T cell polarizing capacity, we compared the quantity and intrinsic quality of induced CD8+ T cells of 2 different DC maturation protocols with all cells from the same donor. Besides differences in the cytokine profile, which could be coupled to increased Th1 and Th17 polarization, we demonstrate in this study that FMKp/IFN-gamma matured DC are twice as effective in inducing cytotoxic T cells against known tumor antigens. Both DCs induced phenotypically equivalent effector memory CD8+ T cells that did not show a significant difference in their intrinsic capacity to kill tumor cells. These findings point to the therapeutic applicability of FI-DC as superior inducers of functional antigen-specific T cells. Their increased chemokine secretion is suggestive of a mechanism by which these DC may compensate for the limited migration observed for all ex vivo cultured DC when applied in patients.

Abstract
Chemotherapy agents have adverse immunotherapeutic effects secondary to inhibition of hematopoietic stem cell proliferation, particularly in committed lymphoblast. Certain anti-cancer drugs have immuno-modulatory properties, although mechanisms are still not fully understood. In the current study, we explored the effects of doxorubicin on peripheral blood CD4(+) and CD8(+) T-cell responses pre- and post-stimulation. Doxorubicin treatment alone had no effects on peripheral blood T lymphocytes and regulatory T-cells in vivo and in vitro. However, CD4(+) T-cells were resistant to doxorubicin and demonstrated more robust proliferation than CD8(+) T-cells after doxorubicin pre-treatment. CD40 ligand and 4-1BB expression on the surface of CD4(+) T-cells were increased after TCR-ligation activation; however, expression on CD8(+) T-cells was not increased. Dendritic cells cultured in the presence of activated CD4(+) T-cells pre-treated with doxorubicin had greater survival rates than those cultured with activated CD8(+) T-cells. Doxorubicin pre-treatment followed by anti-CD3epsilon+anti-4-1BB activation led to proliferation of CD4(+) T-cells and no proliferative effects on CD8(+) T-cells. Our results collectively suggest that doxorubicin pre-treatment in cancer patients may be a more effective way to enhance anti-cancer immune responses by increased antigen-specific CD4(+) Th1 immune responses.
