Research at Lung and Allergy Research Centre
This past year has seen further growth in the Centre, and has been highly productive for all concerned with success in attracting research funding, multiple publications in peer-reviewed journals and book chapters, and a successful patent application.
The research of the group is well supported with grants from NH&MRC, and the Asthma Foundation of Queensland.
Key achievements have included:
- Investigating the importance of antigen presenting dendritic cells (DC) in the pathogenesis of human allergic disease, confirming the importance of DC in asthma.
- Describing the key determinants of host defence against viral infections in chronic respiratory disease, with particular emphasis on the function of plasmacytoid dendritic cells innate interferon production, interleukin 33 and understanding how this varies in people with severe asthma
- Showing that that low doses of the macrolide antibiotic azithromycin over 48 weeks reduce severe asthma exacerbations by 41% compared with placebo.

The Lung and Allergy Research Centre is actively involved in postgraduate supervision, and has numerous student research projects underway.
1. Protection against respiratory virus infections.
Supervisor: Prof John Upham
Contact: j.upham@uq.edu.au +61 7 3443 8024
Immune cells and structural cells in the lungs combine to provide protection against virus infections in healthy people. The project will examine how dendritic cells interact with the epithelial cells that line the airways to provide optimal immunity against respiratory viruses.
2. Asthma, common cold viruses and the immune system.
Supervisor: Prof John Upham
Contact: j.upham@uq.edu.au +61 7 3443 8024
The common cold virus (human rhinovirus) is the most common trigger for flare-ups of asthma, but why an innocuous virus should cause major problems has long been a puzzle. The project will examine the function of various immune cells and regulation of interferon in people with asthma.
3. Understanding how azithromycin prevents exacerbations in severe asthma. Supervisor: Prof John Upham
Contact: j.upham@uq.edu.au +61 7 3443 8024
There is an important need for new interventions in asthma, especially for those whose disease remains poorly controlled despite conventional treatments such as inhaled steroids and long acting bronchodilators. We recently completed the NHMRC funded AMAZES study: this randomised control trial enrolled 420 participants, showing that low doses of the macrolide antibiotic azithromycin over 48 weeks reduce severe asthma exacerbations by 41% compared with placebo (p=0·002). Azithromycin appears therefore to be a highly effective ‘add-on’ treatment in this population, however the mechanisms of action of azithromycin are not well understood, and there is a need to better identify which people with severe asthma are most likely to respond.
4. How efficiently does influenza vaccination work in people with chronic lung disease, and can this be improved through lifestyle interventions?
Supervisor: Prof John Upham
Contact: j.upham@uq.edu.au +61 7 3443 8024
People with chronic lung disease are at increased risk of serious complications following influenza infection. The project will improve understanding of influenza vaccination and examine ways to make vaccination more effective.
