Tumor antigen-specific humoral and cellular immune response as tools for diagnostic and therapy of cancer patients
Final Report Abstract
Our project was a contribution to the characterization of the adaptive immunity in cancer patients. Aim was to identify potential tools which can be used for diagnostics (focus on antibodies) and /or for therapeutical approaches especially immunotherapy (focus on T‐cell epitopes). In the first part of the project, we demonstrated for the 1st time that hydin is a tumor‐associated antigen (more precisely two alternative splicing variants of the hydin gene) which can be targeted by cytotoxic T effector cells (and antibodies). We identified 2 T‐cell epitopes and show that spontaneous T‐cell responses occur against hydin in some cancer patients. In the second part of the project, we could show that radiofrequency ablation is able to stimulate the adaptive immune system against the patient tumor, and propose that RFA could be effectively combined to immunotherapy for the treatment of some cancer patients. Moreover, we show that two RCC‐associated proteins that we previously described are frequently recognized by natural Ab in cancer patients; further investigations are needed to determine whether antibody responses of patients undergoing immunotherapy can be valuable biomarkers of clinical course.
