The approach has been used to induce protective immunity against infectious pathogens, malignancies, as well as prevent the development of autoimmune disorders in animal models. Moreover, DNA vaccines have been tested for clinical use as both prophylactic and therapeutic agents. For these vaccines, </span>plasmid DNA<span> encoding a polypeptide/protein antigen is introduced into a host where it enters host cells and serves as an epigenetic<span> template for the high efficiency translation of antigen. Although DNA immunogens have been shown to stimulate both the cellular and/or humoral arms of the immune system, improving the potency of these vaccines is clearly important. In this regard, several approaches to improve efficacy are currently being tested and will be discussed in this review. One such approach is to improve the DNA plasmid by introducing codon optimization in the DNA plasmid that improves expression and immunogenicity<span> in animals.

Furthermore, priming with such adjuvanted DNAs and boosting with T cell costimulatory molecules further enhances antigen-specific immune response to the DNA antigen. Combining these approaches may be particularly useful against human immunodeficiency virus (HIV) infection, in which both cell-mediated and humoral immune responses are required to fight infection. Ultimately, clinical evidence of these approaches may influence not just how we approach HIV treatment, but also treatments for other infectious diseases, autoimmunity, and cancer.</span></span></p></div>","PeriodicalId":89340,"journal":{"name":"Clinical and applied immunology reviews","volume":"3 4","pages":"Pages 183-197"},"PeriodicalIF":0.0,"publicationDate":"2003-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1529-1049(02)00158-7","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"56629765","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}

Many transgenes, some very innovative, have been shown to inhibit HIV in cultured cells. But translation of such results to humans, or even to animal models of acquired immunodeficiency syndrome (AIDS), has been problematic. Among the reasons for this failure is ineffective gene delivery. Most &lt;/span&gt;gene delivery systems&lt;span&gt; used for this purpose are limited by low production titers, fragility, poor transduction efficiency, waning transgene expression over time, requirements for ex vivo&lt;span&gt; manipulation of target cells that constrain key aspects of these cells' utility on reimplantation, etc. These restrictions both prevent successful anti-HIV gene therapy and limit the scope of ideas as to how anti-HIV gene therapy may be used.&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;span&gt;Application of recombinant gene delivery vectors derived from simian virus-40 (rSV40s) may help to address many of these problems:&lt;/span&gt;&lt;/p&gt;&lt;ul&gt;&lt;li&gt;&lt;span&gt;1.&lt;/span&gt;&lt;span&gt;&lt;p&gt;&lt;span&gt;They transduce all HIV-susceptible cell types (lymphocytes, monocytes&lt;span&gt;, dendritic cells, neurons, microglia, etc.) and their progenitors (e.g., CD34+ cells) with &gt;95% efficiency without selection, whether as &lt;/span&gt;&lt;/span&gt;cell lines or as primary cells, resting or dividing;&lt;/p&gt;&lt;/span&gt;&lt;/li&gt;&lt;li&gt;&lt;span&gt;2.&lt;/span&gt;&lt;span&gt;&lt;p&gt;Transgenes targeting almost every phase of the HIV-1 replicative cycle, from cell entry to virion morphogenesis have been delivered using these vectors.

Nearly all unselected cells treated with two different rSV40s are transduced by both.

The biological function of this recognition is largely unclear. However, since Vγ9Vδ2 T cells are potent cytotoxic effectors capable of killing tumor cells and target cells infected with numerous viruses including human immunodeficiency virus (HIV), simian immunodeficiency virus (SIV), </span>herpes viruses and many others, it is likely that they are involved in antitumor and antiviral </span>immunosurveillance. The observations of tumor-infiltrating γδ T cells with cytotoxic properties and profound quantitative and functional changes in γδ T cells associated with various infectious diseases (including those caused by viruses) are compatible with this hypothesis. For example, the most frequent human peripheral blood γδ T-cell subset expressing Vγ9Vδ2 TCRs is functionally disabled and numerically decreased in some HIV-infected persons. The nonresponsiveness of Vγ9Vδ2 T cells is accompanied by their decreased IFNγ and TNFα production. The overall level of γδ T-cell activation at different stages of </span></span></span>HIV infection<span> may be clinically relevant. At an initial stage of HIV infection, the extremely potent antiviral cytotoxic activities of Vγ9Vδ2 T cells may limit the viral spread. At later stages of disease, Vγ9Vδ2 T-cell dysfunction may contribute to the loss of resistance to opportunistic pathogens (such as atypical mycobacteria) and neoplasms (e.g., lymphomas) frequently associated with HIV infections. The activity of Vγ9Vδ2 T cells both in vivo and can be regulated by nonpeptidic antigens.
