title: A review of biointeractions of Ni and Mg. II. Immune system and oncology.
abstract: Reports of interactions, in vivo and in vitro, between Ni and Mg in humoral and cellular immunity, hypersensitivity and inflammation, and in tumourigenesis are explored from a mechanistic viewpoint. Although Mg is present in much larger concentrations in normal mammalian systems than Ni, similar chemical and physical properties may allow Ni to exchange for Mg at reactive sites with damaging consequences to living organisms. Consequences of such exchanges could involve reduced immunocompetence and related carcinogenic transformation of cells. Mg status and environmental exposure to Ni are conceivable antecedents to possible biological sequelae in humans.
