Summary

Despite much effort, we know little about how the healthy child is protected from infectious disease, and even less about why some children develop inflammatory disorders. Why do some healthy children succumb to overwhelming bacterial infection, while others either survive infection or do not become infected at all? Why do some children suffer crippling juvenile arthritis or life-threatening asthma?

My research program is translational, interdisciplinary and unique in its focus on understanding the role of innate immunity in infectious and inflammatory diseases of childhood. Starting with a population of children with a defined infectious or inflammatory disease phenotype (e.g. undue susceptibility to infection, juvenile idiopathic arthritis), I aim to determine the underlying cellular, molecular and genetic abnormalities responsible for the disease through detailed immunological, genomic and proteomic analysis. The new knowledge generated by this approach will aid diagnosis, elucidate mechanisms of disease pathogenesis and, ultimately, identify novel targets for anti-inflammatory and anti-infectious therapeutic agents.


Current Projects
Genetics of Susceptibility to Childhood Infection
Until very recently, clinical immunologists have focused most attention on patients with a ‘noisy clinical phenotype’—multiple, severe and recurrent infections. Indeed, the origin of primary immunodeficiencies is generally attributed to Bruton’s 1952 description of X-linked agammaglobulinemia in a boy whose repeated pneumococcal infections demanded clinical attention.

Today, enhanced understanding of human immunity combined with ever more sophisticated tools to dissect the immune response have allowed clinical immunologists to look beyond these ‘noisy’, severely immunocompromised patients to individuals with less obvious immune defects. We have entered the era of ‘subtle’ primary immunodeficiencies that will begin to precipitate a fundamental change and expansion of the focus of clinical immunologists.

My lab is involved in searching for subtle genetic immune defects in apparently healthy children who developed serious infections, including invasive pneumococcal infection and severe respiratory syncytial virus infection. This journey towards subtlety is anticipated to translate into better care for our patients through improved diagnosis, combined with tailored treatment and targeted prophylaxis.

Innate Immunity and Lung Inflammation in Cystic Fibrosis
Cystic fibrosis (CF) is the most common, deadly genetic disease affecting young Canadians. Even today, only half of the people living with CF will survive beyond their mid-thirties. New treatments for CF are critically needed.

Lung disease is the major life-limiting factor for people living with CF. Lung injury in CF occurs through a vicious cycle of airway blockage, infection and inflammation. Current CF treatments rely upon physiotherapy to reduce airway blockage and antibiotics to treat the infections, but these treatments do not specifically deal with inflammation. New treatments to simultaneously target airway inflammation are likely to provide substantial additional benefits in improving the quality and length of life for those with CF.

Through synergistic studies harnessing the power of cell biology, chemistry and functional genomics, we are working to identify optimal ‘druggable’ targets responsible for CF airway inflammation and to discover novel anti-inflammatory drugs. Ultimately, these experiments are designed to develop new therapies for safely reducing lung inflammation and improving the quality and length of life of people with CF.

Canadian Healthy Infant Longitudinal Development (CHILD) Study
Over the past 30 years there has been an increasing concern about the effects of environment on health. In particular, since infants spend the majority of their time indoors, there is intense interest in the impact indoor pollution has on the health of our children. Our indoor environment has become a public health priority as growing evidence suggests that unseen environmental contaminants in our living spaces may have important effects on children’s health and development.

The Canadian Healthy Infant Longitudinal Development (CHILD) Study is a multicentre, multidisciplinary, longitudinal, population-based birth-cohort study of 5,000 children enrolled “pre-birth” and followed for five years (www.canadianchildstudy.ca). The main purpose of this study is to determine what aspects of the environment interact with genetic factors to affect children’s health and development. I am a co-principal investigator for the CHILD study and I lead the Vancouver study site.
