The book Cytokines, Stress, and Depression is devoted to the establishment of a link between cytokines and clinical depression. It is based on the proceedings of a meeting that took place in Roscoff, France, on May 14–17, 1998. The purpose of the meeting, as stated in the preface, was to bring together scientists working in the field to discuss "the converging evidence between the brain effects of cytokines and the immunological correlates of depression." The editors acknowledge up front some overlap between the contents of the different chapters and affirm that "nothing has been done to reduce or even to hide it." Indeed, they feel that repetition and redundancy, when it comes from divergent sources, will help make their point.
