The importance of the crosstalk between innate immunity and the adaptive immune response has only recently started to be appreciated. Although it is well recognized that dendritic cells, NK cells, NK-T cells and T cells are all critical for the host response to pathogens, the respective fields that study the biology of these immune cells tend to exist in parallel worlds with minimum exchange of information and ideas. This fragmentation hinders the integration of these fields towards a unified theory of host response. The Aegean Conference: “Crossroads between Innate and Adaptive Immunity” will bring together leading international scientists and experts to address critical areas of Innate and Adaptive immunity something necessary for the development of more efficient scientific exchange and crosspollination between these fields. The purpose of this conference will be to bring together scientists from all over the world to discuss their latest findings on the various aspects of Innate and Adaptive immunity. Abstracts are invited from the international community for the sessions and topic areas identified under Topics. Every session will be chaired by invited speakers who are leaders in their respective fields. The conference has limited participation and a scientific and social program that will maximize scientific interchange through lecture presentations, poster sessions and informal discussions.
