Keystone microbiome meeting 2012: a mountain top experience

The joint Keystone Symposia on ‘Innate Immunity and the Microbiome’ took place in March 2012 in Keystone, Colorado. Gabriel Nunez (U. Michigan, USA) and Akiko Iwasaki (Yale U., USA) organized sessions focused on innate immune sensing of microbe and damage signals, whilst Andrew Gewirtz (Georgia State U., USA), Fergus Shanahan (National U. Ireland, Ireland) and Ruth Ley (Cornell U., USA) organized the microbiome‐focused session. Joint and concurrent talks, and poster sessions between the groups, made for a sensational meeting with active exchange between participants. This meeting point is focused on the microbiome meeting talks and joint sessions.
