Transcriptome analysis reveals a major impact of Tyk2 on the expression of interferon responsive and metabolic genes


ABSTRACT: Peritoneal macrophages of Tyk2-/- and wildtype (wt) mice were compared before and after six hours of LPS treatment. Interferon responsive genes are lower expressed in Tyk2-/- macrophages at the basal level, metabolic genes higher before, but even more after LPS treatment. cDNA from macrophages from three replicates of three Tyk2-/- and three wt mice before and after six hours of LPS treatment, respectively, was hybridized to a microarray and analyzed.

<h4>Background</h4>Tyrosine kinase 2 (Tyk2), a central component of Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling, has major effects on innate immunity and inflammation. Mice lacking Tyk2 are resistant to endotoxin shock induced by lipopolysaccharide (LPS), and Tyk2 deficient macrophages fail to efficiently induce interferon alpha/beta after LPS treatment. However, how Tyk2 globally regulates transcription of downstream target genes remains unknown. Here we e  ...[more]
