Chlamydia pneumoniae is a common respiratory pathogen. Recent studies have
demonstrated the presence of C. pneumoniae in coronary and aortic
atherosclerotic lesions. To study the role of C. pneumoniae in
atherosclerosis, we investigated the susceptibilities of three different
cells of the human vascular wall to infection with C. pneumoniae AR-39.
These cell types were endothelial cells, smooth muscle cells, and
macrophages derived from peripheral blood monocytes. Infection was assessed
by using a direct fluorescent antibody to assess inclusion counts.
Duplicate cell samples were harvested 3 days postinfection and were passed
in HL cells, a susceptible human epithelial cell line, to determine if
infectious organisms were produced. Endothelial cells, smooth muscle cells,
and macrophages were capable of supporting C. pneumoniae growth in vitro.
These results showed that three different cell types known to be important
in atherogenesis are susceptible to infection with C. pneumoniae.
