In this report, we show that in monocytes and T cells IL-10 stimulates tyrosine phosphorylation of the signal transducers and activators of transcription , STAT1 alpha and STAT3 , in a differential manner such that the relative formation of homo- and hetero dimers varies between the two cell types.
 ( protein: activators of transcription, None) , ( cell type: T cells, None) , ( protein: STAT1 alpha, None) , ( cell type: monocytes, None) , ( protein: IL-10, None) , ( protein: STAT3, None) , ( protein: signal transducers, None)
