Coronaviruses

Coronaviruses have emerged during the past ten years from being a group of viruses causing a variety of minor veterinary and human diseases to a major virus group of both clinical significance and molecular biological interest. Against this background, two international coronavirus symposia were held in 1980 and 1983. In recent years, the pace of coronavirus research has been quickened even more by infusion of recombinant DNA technology and establishment of various animal model systems to study the pathogenesis and immunology of coronavirus infections. We therefore organized the Third International Coronavirus Symposium held at Asilomar, California in September 1986, which was attended by more than 120 participants representing a cross-section of both academia and industry. This symposium provided an exciting and stimulating forum for assessing the progress made since the last triennial symposium in Netherland and to suggest the directions for future efforts. This volume collects the scientific papers presented in this symposium. Three loosely defined areas, Molecular biology, Virus-Cell Interaction and Viral Pathogenesis, are separated. These papers very nicely summarize the current status of coronavirus research. They contain a large amount of sequence data, including the complete sequence of a 27 Kb coronavirus genome, a novel mechanism of mRNA synthesis that is unique to coronviruses, and many exciting aspects of coronavirus pathogenesis and immunology. Reflecting the growing interest in the preparation of vaccines, several papers also address the issues related to coronavirus vaccines, which is an area new to this symposium. Dr. Leslie Weiner, who was responsible for the renaissance of modern coronavirus research, added a historical account and future perspectives of coronavirus research. One of us (MMCL) and Volker ter Meulen also provided synopses of the molecular biology and pathogenesis of coronavirus discussed in the symposium. This book will be useful not only to investigators actively participating in coronavirus research, but also too many others interested in an overview of the field.
