  • Title: The effect of iron-deficiency anemia on cytolytic activity of mice spleen and peritoneal cells against allogenic tumor cells.
    Author: Kuvibidila SR, Baliga BS, Suskind RM.
    Journal: Am J Clin Nutr; 1983 Aug; 38(2):238-44. PubMed ID: 6410896.
    Abstract:
    The capacity of spleen and peritoneal cells from iron deficient mice, ad libitum fed control mice, and pair-fed mice to kill allogenic tumor cells (mastocytoma tumor P815) has been investigated. In the first study, mice were sensitized in vivo with 10(7) viable tumor cells 51 and 56 days after weaning. The capacity of splenic cells and peritoneal cells from sensitized and nonsensitized mice to kill tumor cells was evaluated 5 days after the second dose of tumor cells. At ratios of 2.5:1 to 100:1 of attacker to target cells, the percentage 51Cr release after 4 h of incubation was significantly less in iron-deficient mice than control and/or pair-fed mice (p less than 0.05). Protein-energy undernutrition in pair-fed mice had no significant effect. In the second study, spleen cells and enriched T cell fractions were incubated in vitro for 5 days with uv irradiated Balb/C spleen cells in a 2:1 ratio. The cytotoxic capacity against the same allogenic tumor cells was again evaluated. The percentage chromium release at different attacker to target cells was less than 30% in the iron-deficient group compared to either control or pair-fed supporting the results of in vivo sensitized cells. The possible mode of impairment of the cytotoxic capacity is discussed.
