Show moreThe aim of the research described in this thesis was to gain a better understanding of the role of the different immune cells and the different FcR on their cell surface, in antibody therapy and to investigate whether the effectiveness of the tumor-killing mechanisms, activated by the antibodies, can be improved. First, we investigated the role of FcR in various immune responses using a genetically modified mouse, in which all FcR were missing. After defining that role, we studied antibody therapy in a mouse model for melanoma in two different ways: on the one hand, after vaccination using a viral vector that expressed a melanoma antigen, on the other hand, by injecting a melanoma-specific antibody in combination with other substances that activate the immune system.
