Epstein-Barr virus-induced transformation of human B lymphocytes : the effect of l-leucyl-l-leucine methyl ester on inhibitory T cell populations
Epstein-Barr virus-mediated transformation of human B lymphocytes is inhibited by human T lymphocytes as well as by interferon-γ. Removal of the inhibitory cell populations is essential in order to achieve successful transformation in vitro. Cells with the capacity to inhibit outgrowth of lymphoblastoid cell lines can be removed by pretreatment of peripheral blood mononuclear cells with l-leucyl-l
