This book covers the discussions a that workshop on the topics of immune surveillance, mathematical models of HIV infection, complexities of antigen-antibody systems, immune suppression and tolerance, and idiotypie networks. In each of these areas there is reason to believe that advances can be madeeither through interactions among experimentalists and theorists or through the critical look experimentalists and theorists will bring to bear upon one another's work.
