Asterisks indicate changes relative to IFN-γ alone that reached statistical significance in microarray studies (see Materials and Methods). RT-PCR studies indicated statistically significant inhibition by both 19-kDa lipoprotein and M. tuberculosis H37Ra of invariant chain induction by IFN-γ.
Invariant chain is included in this table, although it narrowly missed fulfilling the 1.6-fold criterion for induction by IFN-γ in microarray studies. Inhibition of invariant chain expression reached statistical significance with M. tuberculosis H37Ra and H37Rv but not 19-kDa lipoprotein. RT-PCR studies indicated statistically significant inhibition by both 19-kDa lipoprotein and M. tuberculosis (P < 0.001).
