Abstract

We have evaluated the antitumor effect of IL-2 mini-pellet on the therapy of murine Meth-A sarcoma. After the administration of IL-2 mini-pellet containing 1×10⁶u of IL-2, the serum IL-2 activity was detectable for 72 hours. The s. c. administration of IL-2 mini-pellet and the i. v. injection of LAK cells was effective in inhibiting the tumor growth and could also prolong the survivals. The lytic activites of splenocytes against YAC-1 cells and JTC-11 cells after the administration of IL-2 mini-pellet were augmented. In histological examination on day 7 after the administration of IL-2 mini-pellet, a lot of lymphocytes were invased into tumor tissues. These results suggest that IL-2 mini-pellet can be applied to the adoptive immunotherapy using LAK cells.
