DRUG AND METHOD FOR PROLIFERATING NATURAL KILLER CELLS

摘要

A propagation agent and a propagation method for natural killer cells. A Toll-like receptor ligand such as polyinosinic acid-polycytidylic acid is given into the abdominal cavity of an animal to which lactoferrin is given to propagate the NK cells in the abdominal cavity. Then, the NK cells are taken out from the abdominal cavity to provide the NK cells.
