The lack of Jak3 expression correlated with impaired B cell signaling , as demonstrated by the inability of IL-4 to activate Stat6 in the EBV -transformed cell line from the patient. These observations indicate that the functions of gamma c are dependent on Jak3 and that Jak3 is essential for lymphoid development and signaling.
