Tiivistelmä
As a step toward understanding the role played by host gene expression in the development and pathogenesis of persistent Chlamydia pneumoniae infection, modulation of the host-cell transcriptional response during interferon (IFN)- gamma -induced persistent C. pneumoniae infection of HL cells was examined by a cDNA array and then selectively by a real-time quantitative reverse transcription-polymerase chain reaction. We identified 9 host cell genes whose transcription was consistently altered during IFN- gamma -induced persistent C. pneumoniae infection. The strongest up-regulation of persistent infection, compared with controls (active infection and IFN- gamma ) was identified for insulin-like growth factor-binding protein 6, IFN-stimulated protein 15 kDa, cyclin D1, and interleukin-7 receptor genes. These results suggest that, during persistent infection, C. pneumoniae reprograms the host transcriptional machinery that regulates a variety of cellular processes, including adhesion, regulation of the cell cycle, growth, and inflammatory response, all of which might play important roles in the pathogenesis of persistent C. pneumoniae infection.
