Research Overview

About Professor Alastair Stewart

Professor Alastair Stewart has extensive experience in the field of respiratory and inflammation research. He has published over 200 papers, has had three patents proceed to grant and has served on numerous peer review committees for NHMRC and the scientific advisory boards of several Australian Medical Research Institutes.  Prof Stewart currently Chairs the Therapeutic Technologies Research Initiative (TTRI), The University of Melbourne; Co-Director, Lung Health Research Centre (LHRC), The University of Melbourne; Professor of Pharmacology, School of Biomedical Sciences, The University of Melbourne; and Director of the ARC-Industry Transformation Training Centre (ARC-ITTC) for Personalised Therapeutics Technologies. He is Vice President of the Asia Pacific Federation of Pharmacologists and a member of the Nominating and Programming Committees of the Respiratory Structure Function assembly of the American Thoracic Society.  His editorial roles include Chief Editor of the Translational Pharmacology section of Frontiers in Pharmacology and Senior Associate Editor of the American Society for Mechanical Engineering Journal (ASME), Journal of Engineering and Science in Medical Diagnostics and Therapy. Prof Stewart is developing and applying the concept of mechanopharmacology in drug discovery and ultra-high content screening.

The laboratory conducts, translational and contract research and consultancies.

Laboratory Overview

The Mechanopharmacology Lab is investigating inflammation and fibrosis mechanisms using novel bioassays for drug discovery and characterisation.  A range of systems pharmacology-based analytical approaches are applied using transcriptomic and proteomic data from well-qualified clinical and experimental specimens.  The lab has extensive links to Biomedical Engineering, Chemistry and Physics and strong connections to TTRI, LHRC and ARC-ITTC (Personalised Therapeutic Technologies).

Current projects include:

  • Glucocorticoid sensitivity in structural cells of the airway using Air Liquid Interface Culture.
  • Regulation of mesenchymal cell growth, differentiation and function.
  • Anti-remodelling activity of currently used and potential anti-asthma agents.
  • Impact of extracellular matrix components on the efficacy of anti-remodelling agents.
  • Role of circadian mechanisms in inflammation and tissue remodelling.

Project details may be found on the individual research project pages.

The Mechanopharmacology Lab offers opportunities for placement for BScHons, Masters and PhD candidates and provides a supportive interdisciplinary environment, staffed with highly experienced scientists able to foster translational research goals. Inquiries are welcome.

Student Profile

Final PhD Orations were recently given by the following students:

Meina Li

Meina received a Bachelor of Pharmacy degree in 2010 from Shandong University (China) and a Master’s degree in Pharmaceutical analysis in 2013 from Peking University (China). After graduating from Peking University, Meina joined the Mechanopharmacology laboratory in 2013, with the support of a Chancellor’s scholarship that was established to strengthen the connection between Melbourne University and Peking University.  Meina’s major research interest has been trying to understand the signalling of transforming growth factor beta-induced steroid resistance and identifying drug targets that will spare essential growth and immunoregulatory effects of transforming growth factor beta (thereby facilitating the development of safe modulators of its profoundly significant compromise to steroid activity). In addition to scientific work, Meina enjoys traveling, photography and writing and she would like to share with people how wonderful Australia and the world are using her images and words.

Danica Radojicic

Danica received her Master’s degree in Pharmacy in 2013 from the University of Belgrade (Serbia). She was awarded with two Melbourne international scholarships to join the Mechanopharmacology laboratory, starting her PhD project under Alastair Stewart’s supervision in March 2014. Her research interests include the pharmacology of glucocorticoids and the mechanisms of their actions and insensitivity in the airway epithelium, particularly in asthma. As part of her PhD, she investigated the role of the specific transcriptional repressor PLZF in mediating glucocorticoid effects in the airway epithelium. She also explored the effect of the physiological glucocorticoid, cortisol on the actions of synthetic, therapeutically used glucocorticoids in the airway epithelium, using both human in vitro models, including the air-liquid interface cultures of primary human bronchial epithelial cells and in vivo animal models. Apart from her love for research and science, Danica is also a professional singer and songwriter. She competed in Eurovision, representing Serbia in 2011.
