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 .
