Canine autologous immunotherapy using dendritic cell induced cancer killing immunocytes
Described are compositions of matter, protocols, and treatment means for induction of immune mediated killing in dogs suffering from cancer. The invention provides means of extracting peripheral blood from a canine patient, expanding immunocytes capable of killing cancer cells in vitro, and re-administering said immunocytes into a patient in need of therapy. In one embodiment, immunocytes expanded are T cells possessing tumor cytotoxic activity induced by stimulation of NKG2D.
1. A method of treating cancer in dog by generating immunocytes capable of killing cancer cells in a dog, said method comprising the steps of: a) obtaining canine blood; b) culturing peripheral blood mononuclear cells (PBMCs) isolated from said canine blood with a water-soluble acidic peptidoglycan (WSPG) from sprouts of the plant Solanum tuberosum at a concentration and time frame sufficient to induce cytolytic activity against canine tumor cells; and c) expanding said cells in vitro prior to administration in vivo, and d) administering said expanded cells into a dog suffering from cancer.
