This is the sixth symposium in a series of symposia on immunology organized by IMMUNO covering this time tumor immunology. This volume deals with T cell recognition and CD95-associating signaling, clinical investigations: cells, costimulatory signals and therapeutic approaches: cytokines and vaccines. T Cell Recognition and CD95-Associating Signalling.- Characterization of Antigens Recognized by T Cells on Human Tumors.- Shared and Individual CTL-Defined Antigens on Human Melanoma Cells.- Deficiencies of the MHC Class I Antigen Processing and Presentation Machinery in Tumor Cells.- The Use of HLA Transgenic Mice in Identifying and Targeting Human Tumor Cell Antigens.- CD95-Associating Signaling Molecules.- Clinical Investigations: Cells, Costimulatory Signals.- Adoptive Immunotherapy in Chimeras.- Towards the Development of Immunogenic Colon Cancer Cells for Immunotherapy.- Gene-Modified Dendritic Cells as Vaccines for the Induction of Anti-Tumor Immunity.- Potent Presentation of Soluble Protein Antigens by In Vitro-Generated Dendritic Cells from Peripheral Blood CD34+ Progenitor Cells.- Therapeutic Approaches: Cytokines and Vaccines.- Interleukin-12: Biology and Clinical Studies.- Peptide Vaccines in Melanoma Patients.- Ras Peptide Vaccines.- Idiotype-Based Immunotherapy of Cancers.- Heat-Shock-Protein-Based Vaccines against Cancers and Intracellular Infections.
