ABSTRACT:
In these experiments, B6, D2 as well as the D2.B6-Chr19, and D2.B6-Chr7 congenic lines were infected with M. tuberculosis and lungs were harvested at day 30 and day 70, and RNA was prepared. Three independent RNA samples from each group were converted to labeled cDNAs and hybridized to Affymetrix oligonucleotides arrays (Mouse Genome 430 2.0 array). Hybridization results were analyzed with the Genesifter analysis program to characterize changes in gene expression.

The genetic control of susceptibility to tuberculosis in DBA/2J and C57BL/6J mice is complex and influenced by at least four tuberculosis resistance loci (Trl1-Trl4). To further study the Trl3 and Trl4 loci, we have created congenic mouse lines D2.B6-Chr7 and D2.B6-Chr19, in which resistant B6-derived portions of chromosome 7 (Chr.7) and chromosome 19 (Chr.19) overlapping Trl3 and Trl4, respectively, were independently introgressed onto susceptible D2 background. Transfer of B6-derived Trl3 chro ...[more]
