It is estimated that one third of the worlds population is affected by mild to moderate zinc deficiency, and that this predisposes to a range of infectious diseases. The immunomodulatory effects of zinc have been appreciated for many years, and indeed zinc supplementation is used to treat severe diarrhoeal diseases. This project aims to understand the anti-infective mechanisms of zinc by focusing on macrophages, a key cell type involved in killing invading microorganisms.
