Abstract

Zinc is required for various cellular functions, and abnormal zinc homeostasis gives rise to health problems including skin disease, growth retardation, impaired bone homeostasis, neuronal dysfunctions, and immunodeficiency. Recent studies have provided further support for the important roles of zinc homeostasis in physiology and disease onset: zinc acts as a signaling mediator, recognized as “Zinc signaling”, controlled through zinc transporters. Advances of molecular, physiological, and genetic studies have accumulated evidences showing that zinc signaling participates in health and disease conditions by regulating many cellular events.

I will address zinc signaling contributes to maintain our health, by mainly highlighting the maintenance of epithelium, bone, connective tissues, and immunity, and discuss about “Zinc signal axis”; zinc signal selectively controls intracellular signaling and cellular events. With this realization that zinc signaling is a critical regulatory system of cellular signaling events, it will become a focus of attention for further understanding on the physiological role of zinc homeostasis and human disease.
