Abstract:Although interactions with alveolar macrophages have been well characterized for Mycobacterium tuberculosis, the roles epithelial cells play during infection and disease development have been less studied. We have previously shown that deletion of gene rv3351c reduces M. tuberculosis replication in and necrosis of A549 human type II pneumocyte cells. In the present study, we report that rv3351c is required for lipid raft aggregation on A549 cell plasma membranes during M. tuberculosis infection. Lipid raft agg… Show more
