IL-4-dependent proliferation of BA/F3 cells expressing a growth-negative mutant of the human IL-4 receptor is restored by enforced expression of Bcl-2.

Abstract excerpt

We have studied the regulation of growth and apoptosis in murine BA/F3 cells stably expressing cytoplasmic deletion mutants of the human interleukin-4 receptor (hIL-4R). Previously, we showed that BA/F3 cell transfectants expressing a cytoplasmic deletion mutant of the hIL-4R that lacks the region between Thr(462) and Ala(580), referred to as delta R3, fails to proliferate in the presence of hIL-4. Here we report...
