Functional and genomic changes induced by alveolar transmigration in human neutrophils.

Although the accumulation of neutrophils in the lungs and airways is common to many inflammatory lung diseases, including acute lung injury, the alterations that neutrophils undergo as they leave the peripheral circulation and migrate into the lungs have not been well characterized. Human volunteers were exposed to endotoxin by bronchoscopic instillation. The resulting air space neutrophil accumulation and peripheral blood neutrophils were isolated 16 h later, compared with circulating neutrophils isolated before or after to the pulmonary endotoxin exposure, and compared with circulating neutrophils exposed to endotoxin in vitro.

Practical cancer genetics, genomics and proteomics.

Functional genomics is the science that defines the function of newly identified genes and translates this knowledge into related health and disease. Functional genomics is complex, involving multiple scientific disciplines including computational biology, genetics, physiology, structural biology, and molecular and cell biology. Due to its inherent complexity, the National Institutes of Health (NIH) has termed functional genomics "the science of collaboration.
