Inflammation triggers hypoferremia and de novo synthesis of serum transferrin and ceruloplasmin in mice.

By D L Beaumier, M A Caldwell and B E Holbein


Oil of turpentine was used to induce an artificial inflammation so that we could study its effect on iron metabolism and on synthesis of serum transferrin and ceruloplasmin in mice. It was found that turpentine-induced inflammation triggered the establishment of a hypoferremic state characterized by low levels of serum iron, followed by recovery and a gradual return to normal plasma iron levels. This turpentine-induced hypoferremia and its subsequent recovery paralleled the hypoferremia obtained during meningococcal infection. Moreover, serum transferrin and ceruloplasmin activity levels increased drastically during the recovery from hypoferremia. [14C]leucine incorporation studies revealed a de novo synthesis of both transferrin and ceruloplasmin. Turpentine-induced hypoferremia was also found to provide a protective effect against meningococcal infection which could be partially reversed by exogenous iron. The results of this study suggest that transferrin and ceruloplasmin may be synthesized partly in response to the altered iron metabolism observed during hypoferremia
