CYTOKINES FROM NATURAL KILLER OR T CELLS

摘要

Cell-free preparations of a cytokine produced by natural killer (NK) cells activated with interleukin 2 (IL-2) or produced by CD4+ T cells activated with anti-CD3 monoclonal antibody are described. This cytokine induces antibody secretion by activated B cells. Methods for producing the cell-free supernatants containing the cytokine are also described.
