"The combination of arsenic, interferon-alpha, and zidovudine restores an ""immunocompetent-like"" cytokine expression profile in patients with adult T-cell leukemia lymphoma."
Here, we report that IL-2-dependent ATL cell lines also express IL-4Ralpha and respond to IL-4, which was verified by the activation of cytoplasmic transcriptional activator Stat6 protein.
These results indicate the activation of IL-4/IL-4 receptor system in leukemic cells from some ATL patients and suggest the possible involvement of the system in the proliferation of leukemic cells and the leukemogenesis in ATL.
