tokens: We conclude that ( 1 ) HTLV-I infection per se does not result in a constitutive phosphorylation of the Jak3 , STAT3 , and STAT5 proteins ; ( 2 ) malignant transformation in at least some cases of ATLL does not require the constitutive , but may require IL-2 -induced , activation of the IL-2R Jak/STAT pathway ; and ( 3 ) there are major differences in T-cell immortalization mechanism ( s ) which appear to involve SHP-1 and target molecules for rapamycin and RAD .
