Transcription profiling of mouse C57BL6J and DBA2J strains when Chlamydia infected

ABSTRACT: C57BL/6J mice were 105-fold more resistant to Chlamydia psittaci infection than DBA/2J mice by LD100 determinations. Linkage analysis using BXD recombinant inbred strains revealed a single effector locus at a 1.5 Mbp region on chromosome 11 encoding a cluster of three p47GTPases (Irgb10, Igtp, and Iigp2). Western blots of infected tissue showed that Irgb10 was elevated in resistant mice and one of the two possible Iigp2 protein isoforms was preferentially expressed in susceptible mice. The BXD39 strain, susceptible at Irgb10 and resistant at Iigp2, had an intermediate phenotype, implicating the non-redundant role of these p47GTPases. C57BL/6J and DBA/2J exhibited a difference in IFNg dependent chlamydial control, which was reversible by Iigp2 siRNA knockdown. Microarrays of infected perito
