The 4th ECI will cover all fields of modern immunology and adhere to a 4-track structure covering the topics innate immunity, adaptive immunity, diseases of the immune system and immune interventions. The 4-track program will streamline symposia, workshops as well as poster sessions enabling easy crosstalk between topics and types of sessions planned. In fact, novel forms of immune interventions represent one of the most exciting success stories of modern medicine. Thus, a special focus of the 4th ECI will be put on the fine balance between basic and applied/translational research. Delegates will be offered 150+ talks by invited speakers, plenary lectures by ‘immunology icons’, more than 400 oral presentations selected from abstracts, as well as guided poster walks. A special emphasis will be devoted to the education of our young scientists and students. In addition, the 4th ECI will be embedded into a number of satellite meetings dealing with related topics.
