Outline of Final Research Achievements

The present study accomplished a unique assay system to illuminate cytotoxicity / proinflammatory effects of air-polluting substances: i.e., particulate matter with diameters of ca. 2.5 micrometers and smaller (PM2.5). During the designated research term, the researchers collected PM2.5 particles in Fukuoka and Kawasaki cities and made use of them for the following studies:① we greatly improved the optical performance of the bioluminescent probes, designed to image cytotoxicity or proinflammatory effects of PM2.5, by fabricating artificial luciferases or the specific substrates. ② The cDNA constructs encoding the probes were stably introduced into mammalian cells and thus accomplished the above assay system. ③ This assay system was then geared to a custom-made multichannel light detector, allowing a high throughput determination of light. The present studies ware finally reported in 8 scientific papers, 13 presentation, 1 book publication, 10 review articles, and 7 patent filing.
