Experimentally, immunogenicity may be enhanced by the use of new delivery technologies, by coadministration of cytokines and pathogen-associated molecular patterns, or by fusion of antigens into molecular domains that enhance antigen presentation. More specifically, the immunogenicity of DNA vaccines may benefit from increased protein synthesis, increased T-cell help and MHC class I presentation, and the addition of a range of specific cytokines and pathogen-associated molecular patterns that increase activation of the innate immune system. Importantly, viral-vectored vaccines that act through the induction of one or more of these factors also may benefit from cytokine coadministration and increased antigen presentation. In order to increase immunogenicity to the level achieved with viral-vectored vaccines, various synergistic components may need to be incorporated into DNA vaccines. From the perspective of the future clinical use of DNA vaccines, it has been suggested that antigen presentation should be improved and cytokine coadministration attempted. However, even with these modifications, it is likely that the primary use of DNA vaccines may be as primers for viral-vectored vaccines, rather than as single agents. This review discusses the approaches used to enhance DNA vaccine immunogenicity, with a primary focus on fusion strategies that enhance antigen presentation.</p>","PeriodicalId":50605,"journal":{"name":"Current Opinion in Molecular Therapeutics","volume":"12 1","pages":"47-54"},"PeriodicalIF":0.0,"publicationDate":"2010-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"28700308","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}

Copy number variations (CNVs) in the human genome are the result of insertions, deletions, duplications and complex multisite variants, affecting approximately 10 to 12% of the genome and covering a higher number of nucleotides than SNPs. Several methods are used for the detection of CNVs, including approaches based on hybridization, such as arrays, PCR amplification, FRET and sequencing. These methods can identify microscopic structural variations (> or = 3 Mb in size), as well as submicroscopic structural variations (approximately 1 kb to 3 Mb in size). CNVs can affect drug metabolism and disease susceptibility. Therefore, the effect of variations in the copies of genes on the efficacy and toxicity of therapeutic agents needs to be well established at both pharmacokinetic and pharmacodynamic levels prior to the use of these agents clinically.

Familial LPL deficiency is a rare, autosomal-recessive disorder of lipoprotein metabolism that is characterized by severe hypertriglyceridemia with episodes of abdominal pain, acute pancreatitis and eruptive cutaneous xanthomatosis. The lack of functional LPL in patients with LPL deficiency causes an accumulation of triglyceride (TG)-rich lipoproteins in the plasma. The LPLSer(447)X variant is associated with decreased levels of plasma TGs and increased HDL cholesterol concentrations compared with wild-type LPL. Preclinical studies evaluating alipogene tiparvovec in a mouse model of LPL deficiency demonstrated a long-term, dose-dependent correction of the lipid abnormalities. The first clinical trials in patients with LPL deficiency appear promising, with a significant decrease in the levels of plasma TGs observed in the first 3 months following the administration of alipogene tiparvovec, and an increase in local LPL activity and protein levels observed after 6 months. In addition, a decrease in pancreatitis frequency was observed during a 3-year follow-up period. At the time of publication, a phase II/III trial in patients with LPL deficiency, being conducted to further support the submission of an MAA to the EMEA for alipogene tiparvovec, was ongoing.
