Mineral deficiency effects on the generation of cytotoxic T-cells and T-helper cell factors in vitro

Abstract

Generation of cytotoxic T-cell response of splenocytes was studied in vitro under copper, magnesium and zinc-deficient conditions. Viability of the short-term lymphocyte cultures in the deficient media was comparable with control condition viability. Cell mediated lympholysis (CML) was analyzed in an alloantigen-stimulated mixed lymphocyte culture (Balb/c versus CBA/H mice) using a 51Cr release assay. Lymphocytes cultured in copper and magnesium-deficient media failed to generate specific lysis to allogeneic target cells, whereas lymphocytes cultured in zinc-deficient media did generate T-killer cell activity at reduced levels. In examining the site of mineral deficiency effects, the actions of T-helper cell-produced factors was studied. There was no production of T-cell replacing factor (TRF) in any of the elementally deficient media by cultured splenocytes. The addition of TRF produced under normal control conditions to copper-deficient media completely restored the CML, whereas only a partial restoration of the CML was noted for the magnesium and zinc-deficient cells. The defect in the CML in the copper-deficient media appears to be focused on the T-helper cell, but magnesium and zinc deficiency effects appear to also be at ...Continue Reading

Atopic Dermatitis

Atopic dermatitis is a chronic inflammatory genetically determined disease of the skin marked by increased ability to form reagin (IgE), with increased susceptibility to allergic rhinitis and asthma, and hereditary disposition to a lowered threshold for pruritus.
