Another piece in the puzzle

Pulmonary ischemia–reperfusion injury is complex and involves many cell types and mechanisms of action. Van Putte and coworkers have attempted to provide insight into and describe some of the complex components of this process. Their study describes two new components of the multifaceted process of reperfusion injury. The time-dependent course of neutrophil activation and the discovery of programmed cell death in reperfused lung tissue are two new pieces of a complex puzzle.
