Abstract
Alloimmunization was combined with lymphokine activated killer (LAK) cells to assess its effect on mammary carcinoma in rats. The animals were injected with both irradiated allo-splenocytes and syngeneic LAK cells. Metastatic lung nodules were markedly reduced using combined therapy when compared with the transfer of LAK cells or alloimmunization alone. IL-2 activity in the serum of alloimmunized rats could be detected. This activity, maintained in vivo for one week, may be responsible for enhancing the antitumor effect of transferred LAK cells.
