Whereas the Jak kinases Jak1 and Jak3 and the signal transducer and activator of transcription proteins Stat3 and Stat5 are activated in normal T cells in response to IL-2 , this signaling pathway was constitutively activated in HTLV-I -transformed cells .
 cell type: T cells; protein: Stat5; protein: Stat3; protein: Jak3; cell line: HTLV-I -transformed cells; cell type: normal T cells; protein: transcription proteins; protein: Jak1; protein: Jak kinases; protein: IL-2
