Advanced age is associated with an increased incidence of immune and degenerative disorders, mediated by metabolic changes, dysregulation of proinflammatory signals, and apoptosis. Concurrently, there is a progressive decline in self-recognition. Investigations on biologic functions of transferrin (Tf) other than iron transport showed that Tf has a profound cytoprotective (anti-apoptotic) effect on lympho-hematopoietic cells and the thymus, and interferes with stress-induced signals.

Recent studies in lymphohemopoietic cells show that transferrin (Tf), a pivotal component of iron transport and metabolism, also exerts cytoprotective functions. We show here in a murine model that Tf interferes with Fas-mediated hepatocyte death and liver failure. The mechanism involves the downregulation of apoptosis via BID, cytochrome c, caspase-3 and caspase-9, and upregulation of antiapoptotic signals via Bcl-xL.
