Vision Statement:

My research focus is on mechanisms of lung inflammation, particularly, lung inflammation caused by infection, cigarette smoking and air pollution. This research covers a broad range of clinical conditions such as pneumonia, chronic bronchitis and emphysema and acute respiratory distress syndrome. Current research efforts address the pivotal role of the systemic inflammatory response induced by lung inflammation and the downstream effects of this systemic response on other organ systems in particularly the vascular system. The systemic response is an integral part of acute and chronic lung inflammatory conditions and an important prognostic signature. The research is multidisciplinary and integrated research efforts include work at molecular, cellular, organ, intact animal and human levels.

Research Interests:

Respiration, Immunology, Cardiology, Physiology, cell biology

Research Sumary:

There is a strong association between acute lung conditions such as pneumonia and heart attacks or chronic lung conditions such as COPD and disease such as heart disease, diabetes mellitus, osteoporosis and cancer. Systemic inflammation is thought to be the link between lung disease and these other conditions. The mechanisms how inflammatory lung conditions such as pneumonia, COPD causes vascular and heart disease, are poorly understood. Experiments from our own and other laboratories have shown when air pollution particles or cigarette smoke are inhaled, they cause inflammation in the lungs, but also increase inflammatory molecules in the circulating blood. We postulate that inflammation in the lung spills over in the blood stream, activates the circulating blood cells and blood vessels promoting the formation of atherosclerosis that results in heart attacks and stroke. In recent published studies we have made two novel observations; 1) excess inflammatory molecules in the circulation are cleared or removed by the lung, 2) during lung inflammation this clearing function of the lung is compromised. In this study we proposed to study the links between lung inflammation and systemic inflammation that are thought to promote blood vessel disease. We will focus on event in the lung that is; how does the lung remove key inflammatory molecules from the circulation and secondly, what molecules spill over from the lung to the blood stream during lung inflammation caused by infection and exposure to air pollutants. We will use animal models to study the mechanisms how the lung clear the circulation of harmful molecules and what happened when the lung become inflammated to compromise this crictical important lung function. We will also test this hypothesis in humans and determine what harmful molecules are removed from blood by the lung and how this is compromise with lung disease. We will use several state of the art techniques to identify these molecules. We expect that these experiments will identify new or novel molecules and clarify how the lung function as a organ the keep the blood stream clean.

We believe this research will identify key molecules that participate in the systemic inflammatory response and will allow the development of therapeutic interventions targeting these molecule. Ultimately targeting the systemic inflammatory response will reduce the morbidity and mortality related to acute (pneumonia) and chronic (COPD) lung conditions.

Education:
Dr. van Eeden graduated from the University of Stellenbosch, Cape Town, South Africa in 1975, and after four years as a family practitioner resumed his studies in Internal Medicine at the same University. He trained and certified in Pulmonology and Critical Care in 1985, did his Masters degree and was promoted to Director of Critical Care, Tygerberg Hospital, University of Stellenbosch in 1989. He did his PhD in the Department of Experimental Medicine, University of British Columbia with Dr James C Hogg as his supervisor. He graduated in 1995 and completed his Canadian specialist examination (FRCPC) in 1996.
