Název v původním jazyce

Transcriptional profiling of host responses in mouse lungs following aerosol infection with type A Francisella tularensis

Popis výsledku v původním jazyce

Tularaemia caused by inhalation of type A Francisella tularensis bacteria is one of the most aggressive infectious diseases known, but the reasons for the very rapid spread of the organism from the lungs to internal organs and the ensuingmortality are unknown. The present study used the mouse model to examine in detail the host immune response in the lung. After an aerosol challenge with 20 c.f.u. of the type A strain FSC033, all mice developed clinical signs of severe disease, showed weight loss by day4 of infection and died the next day. Histopathological findings in the lung revealed acute inflammation and intense vasculitis and perivasculitis on day 4. Gene transcriptional changes in the mouse lung samples were examined on days 1, 2 and 4 of infection using a cDNA microarray with 20,600 mouse clones representing 18,500 genes. In total, 424 genes were found to be differentially expressed, some of which were both up- and downregulated at different time points, 192 of which were upre
