American Journal of Transplantation: Volume 14, Number 6, June 2014

On the cover this month: Immunity has generally been understood as being at odds with the myriad microbes that thrive on and in us, but increasingly there is recognition that human immunity coexists and productively interacts with our microbiota. This intersection and its implications for transplant immune management are comprehensively reviewed by Alegre et al (page 1236 ). This month's issue also takes a deep dive into the complexities of program outcomes monitoring, specifically examining the Bayesian methodology being adopted by the Scientific Registry of Transplant Recipients. See the editorial by Schold and Axelrod (page 1231 ), and viewpoint (page 1271 ) and article (page 1310 ) by Salkowski et al. Cover design by Ken North, North Design Group.
