This volume concentrates on the most relevant oligonucleotide research and drug development areas and emphasizes the basic mechanisms and biology of oligonucleotide reagents. Chapters are devoted to RNAi, oligonucleotide delivery, and immunomodulation. Because of the advanced stages of oligonucleotide-based drug development, preclinical and clinical data are also presented by leaders in the field.
