The city of Chicago will be the site of the 2010 Joint Meeting of the International Cytokine Society (ICS) and the International Society for Interferon and Cytokine Research (ISICR). This annual conference brings together the top international scientists in the cytokine field. It is also the most popular, drawing over 800 participants to Montreal in 2008 and Lisbon in 2009.As this event unites the biomedical expertise and energies of the two major societies, we thought a city with great energy like Chicago would be the perfect place to host this year’s event. This meeting has become the world’s most important conference on basic and clinical research on cytokines. In addition to an exciting line up presentations, posters and sessions on cytokines, this conference will also feature opportunities to experience some of the best of Chicago.
