abstract：:Interleukin-6 (IL-6) is an important B-cell growth and differentiation factor. IL-6 treatment of the human lymphoblastoid cell line, SKW6.4, leads to increased IgM production. We have previously shown that IL-6 induces activation of JAK1 and JAK2 in human B cell lines. A chimeric IL-6 receptor, comprised of the intrac...
