Natural and Induced Cell-Mediated Cytotoxicity: Effector and Regulatory Mechanisms contains the proceedings of the Erwin Riesch Symposium organized on the occasion of the Fifth Centennial of the University of Tübingen in Germany on October 20-23, 1977. The symposium provided a forum for reviewing the progress that has been made in understanding the effector and regulatory mechanisms underlying natural and induced cell-mediated cytotoxicity. Topics covered range from the immunobiology of natural killer cells to the role of macrophages as regulator, accessory, and effector cells in cytotoxicity. Comprised of 27 chapters, this book begins by analyzing the characteristics of natural cytotoxic cells in mice, followed by a discussion on the generation in vivo of mouse natural cytotoxic cells and the role of cytotoxic T cells in the local defense against solid tumors. Subsequent chapters focus on the natural cytotoxicity of human lymphocytes; opposing effects of interferon on natural killer and target cells; susceptibility of cloned melanoma to natural cytotoxicity; and cell-mediated immunity against avian virus-induced tumor cells. The book also examines alternative routes of entry for cell surface antigens into the immune system before concluding with a chapter that considers interferon induction by Corynebacterium parvum. This monograph should be of value to students, researchers, and practitioners in the fields of biology and immunology.

Our current understanding of a/~ T cell receptor (TCR) ex­ pressing T cells advanced from function and specificity to the molecular organization ofthe TCR.We now know that the TCR a and ~ chains together express specificity for (antigenic) peptides presented by the "responder" M H C allele, thus explain­ ing the phenomenon of MHC restriction at a molecular level. Surprisingly even though our perception of the molecular organization of the y5 TCR is well advanced, current knowledge of function and specificity of the y5 T cell subset is poor. There­ fore it appeared rather timely to bring together scientists pioneering research on y5 T cells forthe International Workshop on Function and Specificity ofy5 Tcells,held October11-14, 1990 at Schloss Elmau/Bavaria, FRG. Besides offering a scientific forum for open discussions, it was also hoped that such a workshop would be seminal for collaborative interactions and personal relationships among scientists "addicted" to y 15 T cells.
