https://www.selleckchem.com/products/atogepant.html Compared with conventional vaccines, the main advantage of DNA vaccine-based methods is its continued expression of the plasmid-encoded antigens followed by the induction of subsequent humoral and cellular immunities. DNA vaccines are currently used in animal models, but limited success has been obtained for use in clinical applications due to their poor immunogenicity. Various strategies are attempted to improve the induced immune response of DNA vaccines. It has been demonstrated that co-administration of molecular adjuvants with DNA vaccines is a promising approach to effectively elicit protective immunity by increasing the transfection efficiency of DNA vaccines. Genetic adjuvants are incorporated to promote activation of the transfected local antigen-presenting cells (APCs) and immune cells in the draining lymph node and polarization of T-cell subsets to decrease T-cell tolerance to the specific antigen. Here we provide an overview of different types of genetic adjuvants. The aim of the current chapter is to present a framework for the construction of a gene-based vaccine and adjuvant. Moreover, we describe the application of DNA vaccines co-administered with different types of genetic adjuvants and the methods to evaluate their potency in the mouse models.CpG Oligonucleotides (ODN) are immunomodulatory synthetic oligonucleotides specifically designed to stimulate Toll-like receptor 9. TLR9 is expressed on human plasmacytoid dendritic cells and B cells and triggers an innate immune response characterized by the production of Th1 and pro-inflammatory cytokines. This chapter reviews recent progress in understanding the mechanism of action of CpG ODN and provides an overview of human clinical trial results using CpG ODN to improve vaccines for the prevention/treatment of cancer, allergy, and infectious disease.Alphavirus vectors have been engineered for high-level gene expression relying originally on replication
