Synopsis

nomenon [26]. Indeed, Krieg et al. [21] showed that the elimination of the CpG in a particular ODN invariably abolished immune stimulation, but changes in the ODN sequences that did not affect the CpG or the flanking bases did not alter the immuno- stimulatory (IS) effect. Furthermore, they extended the initial observations of the IS effects to non-palindromic CpG-enriched ODN [21]. Subsequent studies showed that CpG-enriched ODN also induce the secretion of IL-6 and IL-12 [19] and IFN-a [6, 27]. By adding or deleting various IS sequences (ISS)-ODN to or from different pDNAs, it was demonstrated that the ISS have a pivotal role in the induction of the subsequent immune response to the gene product in gene-vaccinated animals. The enhanced Thl immune response induced by gene vaccination is the consequence of the activation of the innate immune response by the ISS in the pDNA backbone [30, 31], rather than the low dose of intracellularly produced antigen. The cell activation products induced by the ISS, i. e. , IFN-a [3], IFN-~ [43], IL-12 [37], and IL-18 [25], are established inducers of IFN-y synthesis and promote the differentiation of naive T helper cells to Thl lym- phocytes. Thus, the ISS activate the precise innate cytokine network required to pro- mote Thl differentiation (see Fig. 1). In a recent study it was demonstrated that this ap- proach is also applicable to a protein antigen.

About this title

From the Back Cover

Vaccination has been established as an efficient procedure to prevent infections. Over the past few years, a new method of subunit vaccination has attracted the attention of immunologists. Despite its popularity, it is only recently that the basic mechanisms that drive the immune response to the encoded antigen have begun to unfold. The multidisciplinary approach of this book outlines the basic characteristics of gene (DNA) vaccination, the role of APCs or bone marrow derived cells in the induction of the immune response. It points out the potential applications for various infectious and allergic diseases and describes the multifaceted properties of DNA in initiating and determining the subsequent immune responses to the encoded antigen.
