New imaging advance illuminates immune response in breathing lung
Date:12/20/2010

nhalation of air, allergens, toxins and pathogens. The lung also is in constant contact with inhaled air and with circulating blood cells.

"As a result of achieving video-rate imaging of events within the lung, we've shown how the immune system behaves during normal function and how tissues are affected in acute lung injury," Looney said. "For other disease processes in other organs, we hope to define how collections of cells participate and how they're organized."

In the future, the team plans to miniaturize the stabilizing rig in order to image live tissue biopsies.

"Many different specialties of clinical scientists and pathologists can use this imaging method to learn how disease progression unfolds, but miniaturizing the rig to image biopsied tissue would be a tremendous improvement," Krummel said. "In real-time, for instance, we can catch how cells interact with tumors and observe whether they promote growth or rejection, and whether medical therapy is working."
