  • Title: [Ambiguous action of splenocytes from tumor-bearing mice on the formation of metastases in the lungs of mice in an adaptive transfer system].

    Journal: Biull Eksp Biol Med; 1984 Nov; 98(11):598-600. PubMed ID: 6509179.
    Abstract:
    The growth of the syngeneic tumor MMT1 in C3H of mice was accompanied by significant changes in the spleen weight and in the number of nucleated cells in the spleen. Tumor excision led to the reduction of these indicators to the initial level. Adoptive transfer of splenocytes from tumor-bearing to intact mice exerted an inhibitory (on days 5, 14) or stimulatory (on day 25) action on the development of experimental metastases in intact animals depending on the tumor growth time. The result of splenocyte transfer from the operated on mice depended on the presence or absence in donors of tumor growth relapses (the development of lung metastases was inhibited only by splenocytes from donors with tumor relapses). Splenocyte transfer from mutant nude mice, both tumor-bearing and intact, produced an equipotent inhibitory effect. It is suggested that different mechanisms may be responsible for the development of metastasis inhibition in normal tumor-bearing mice and in tumor-bearers with T-cell system immunity deficiency.
