My main interest currently is the role of labile zinc in cardiovascular physiology and disease. I co-discovered labile zinc and its role in cell signalling in the 1990s. The zinc fluorophore our group developed in 1990s is used around the world by researchers. I have more than 90 publications on zinc. I have been involved on a wide range of committees at the University of Adelaide and Basil Hetzel Institute for Translational Health Research. I have extensive experience as a post graduate coordinator in Medicine and am currently an Honours Coordinator for Medicine in the Adelaide Medical School.

Dr Zalewski is a Post-doctoral fellow Level C in the School of Medicine at the University of Adelaide. He heads the Zinc Biology Research Laboratory at the Basil Hetzel Institute for Translational Health Research. He has had a major interest in the cellular biology of Zn and particularly, the development of techniques to visualize and quantify the more dynamic, labile pools of Zn and their role in the regulation of apoptosis. In 1996, he was awarded an NHMRC grant to develop zinc fluorophores that would enable measurement of labile Zn in normal and diseased cells and tissue. The prototype Zinquin is used around the world to study cellular biology of Zn, although several types of zinc fluorophores are also now available. He has also developed a rapid and sensitive fluorescence-based assay that allows measurement of labile Zn in body fluids, as a potentially more relevant biomarker of zinc status than total plasma zinc. This test was adapted to measure zinc in sputum and bronchoalveolar lavage. His group was the first to identify the link between labile cellular zinc and suppression of apoptosis (1993). They were also were the first to describe the release of Zn from metalloproteins in apoptotic cells (in 1994), featuring on the cover of the journal, and the rapid activation of procaspase-3 in Zn-deficient cells (1999). He chaired the session “Zinc and control of cell death” for the 1st, 3rd and 5th International Conferences on Zn Signalling held in Grand Cayman, Aarhus and Jerusalem. In February 2007, he was invited to a workshop in Bangladesh under the auspices of Harvest Plus (New York) to participate in the planning of a trial of Zn fortified rice with the aim of reducing childhood mortality due to diarrhea, where he advised on methods of assessing Zn deficiency in these children and measuring outcomes of the trial. Between 2004 and 2010, he was awarded three NHMRC project grants as CIA to study Zn in the airway epithelium and techniques to monitor it in asthmatic patients. His group was the first to image zinc in the airway tissue showing that the respiratory tract (from nasal epithelium through to bronchiolar epithelium) contains a rich lining of labile zinc. Removal of this zinc in isolated airway epithelial cells rendered them highly vulnerable to noxious agents, including oxidants. His group then showed depletion of this zinc in a murine model of allergic airway inflammation and significantly decreased zinc in the induced sputum of asthmatics. In the mouse model, there was a strong association between low dietary Zn intake and severity of airway epithelial cell death, airway inflammation and bronchial hyper-responsiveness to methacholine. He was invited to review this field of research for Current Opinions In Pharmacology. In 2010, a productive collaboration with Prof Sandy Hodge enabled the first measurements of Zn and its specific transporter proteins in alveolar macrophages (AM) in the context of long-term smoking and COPD. Declines in BAL Zn in long-term smokers with COPD were shown. This may, in part, contribute to the impaired phagocytic ability for AM from COPD subjects, as positive associations were found between Zn levels and AM phagocytic ability. Currently, he is a co-chief investigator with Prof Hodge on an NHMRC grant (2016-18) looking at autophagy in COPD. Recent productive collaborations have been with an islet transplant consortium (Prof Toby Coates) and CSIRO (Prof Michael Fenech). In 2011, he was invited to write a chapter on zinc in cell proliferation and cell death for a new book on zinc in human health. In 2013 he commenced a collaboration with a vascular research group led by Prof John Beltrame providing an opportunity to extend the work of zinc in the airways to blood vessels. This led to the establishment of the endothelial biopsy technique and its use to study zinc-related biology in ex-vivo arterial endothelial cells from patients.
