Extracellular thioredoxin: a therapeutic tool to combat inflammation

Abstract

The manipulation of cellular redox status has emerged as a promising therapeutic strategy to prevent uncontrolled inflammatory response. Thioredoxin is an important regulator of cellular redox homeostasis, which catalyzes the reduction of disulfide bonds. Human thioredoxin, originally identified as a secretory protein ADF, has been implicated in a wide variety of redox regulations in both intracellular and extracellular compartments. This review includes a summary of the evidence available supporting the employment of the beneficial properties of thioredoxin to combat inflammation, an evaluation of the potential of redox-based therapy for the treatment of inflammatory diseases, and a discussion on the conceptual model of a redox-sensitive signaling complex, Redoxisome, consisting of thioredoxin and its redox partners.
