Recent data indicate that macrophages become functionally deactivated during mycobacterial infection. We studied macrophage deactivation by examining the expression of a panel of IFN-gamma-inducible genes and activation of Janus Kinase (JAK)-STAT pathway in Mycobacterium avium-infected macrophages. Reduced expression of IFN-gamma-inducible genes-MHC class II gene E beta; MHC class II transactivator; IFN regulatory factor-1; and Mg21, a gene coding for a GTP-binding protein-was observed in M. avium-infected macrophages. Decreased tyrosine phosphorylation and DNA binding activity of STAT1 in M. avium-infected macrophages stimulated with IFN-gamma was observed. Tyrosine phosphorylation of JAK1, JAK2, and IFN-gamma R alpha was also reduced in infected cells. Northern and Western blot analyses showed that a down-regulation of IFN-gamma R alpha- and beta-chain mRNA and protein occurred in M. avium-infected macrophages. The down-regulation of IFN-gamma R and inhibition of STAT1 activation were time dependent and required 4 h of infection for down-regulation of the IFN-gamma R and 8 h for STAT1 inhibition. These findings suggest that M. avium infection inhibits induction of IFN-gamma-inducible genes in mouse macrophages by down-regulating IFN-gamma R, resulting in reduced phosphorylation of IFN-gamma R alpha, JAK1, JAK2, and STAT1."xsd:string |
