Molecular Characterization of Treponema denticola infection-induced bone and soft tissue transcriptional profiles

The objectives of this investigation were to examine changes in the host transcriptional profiles during a Treponema denticola infection using a murine calvarial model of inflammation and bone resorption. T. denticola ATCC 35404 was injected into the subcutaneous soft tissue over the calvaria of BALB/c mice for 3 days, after which the soft tissues and calvarial bones were excised. RNA was isolated from infected soft tissues and calvarial bones and analyzed for transcript profiles using Murine GeneChip MG-MOE430A Affymetrix arrays to provide a molecular profile of the events that occur following infection of these tissues.
