摘要: Analysis of cytokine and differentiation antigen expression in human natural killer (NK) cells revealed that interleukin 13 (IL-13) interferon γ (IFN-γ) are produced at sequential stages during irreversible IL-12–induced differentiation. In NK cell clones, polyclonal CD3−CD161+CD56− peripheral lymphocytes, IL-4 induced the proliferation both IL-13+ T cells, whereas IL-12 allowed a proliferation-independent accumulation IFN-γ+ cells. These data disproved NK1-NK2 hypothesis challenge current helper 1 (TH1)-TH2 paradigm. We propose environment regulates type 2→0→1 developmental progression, with needed for terminal delaying this process, rather than versus 2 decision 0 cell.
