Tobacco Product Research Program

The World Health Organization (WHO) estimates that 9 out of 10 people worldwide breathe polluted air- this includes you. This pollution can come from a wide variety of sources, including air pollution caused by industries, traffic (think about all those cars, buses and trucks on the road) and even indoor cooking. In essence, breathing polluted air day-in and day-out can cause heart disease, many types of cancer and chronic lung diseases. Other sources of pollution include many common occupations (such as coal mining, welders).

Did you also know that cigarette smoke contributes to the toxicity of common air contaminants and remains the single largest cause of preventable death worldwide?

Therefore, understanding the impact of air pollution and cigarette smoke has been a crucial factor in implementing air quality guidelines and anti-tobacco campaigns. Despite this knowledge, we are seeing a surge in the use of emerging tobacco products such as e-cigarettes (“vape”), heat-not-burn products (IQOS) and hookah (includes e-hookah), particularly with young adults. However, the health effects of these products are almost completely unknown.

the aryl hydrocarbon receptor attenuates pulmonary inflammation caused by cigarette smoke

For this reason, one of the main programs of research for my laboratory is on tobacco-induced disease. We utilize in vitro and mouse inhalational models of tobacco smoke and other products to understand the pathogenesis of diseases such as chronic obstructive pulmonary disease (COPD). COPD is currently the 3rd leading cause of death world-wide.

One of my research interests lay in identifying new molecular mechanisms involved in the pathogenesis of COPD, particularly ones that offers therapeutic potential or a novel susceptibility marker. To this end, we have been investigating the role the aryl hydrocarbon receptor (AhR) in the pathogenesis of smoke-induced lung disease. Our findings show that activation of the AhR by cigarette smoke suppresses inflammation and apoptosis in the lung. Using genetic and biochemical approaches, my research is focused on establishing that the AhR is a novel and important regulator of inflammation, oxidative stress and apoptosis. In conclusion, we wish to understand the role of the AhR in preventing morphological features of COPD in the lung and determine the molecular mechanism by which the AhR provides protection against the deleterious effects of tobacco smoke and other inhalational toxicants.

Biomedical Cannabis Research Program

Carolyn Baglole Cannabis Research Program

With my expertise in inhalation toxicology and mechanisms of disease pathogenesis, I have developed a new Cannabis Research Program fro my laboratory. Cannabis sativa indica- referred to as cannabis (marijuana) – is one of humanity’s oldest cultivated plants.

Cannabis has been used as a therapeutic agent for the management of pain, neurological conditions such as epilepsy and multiple sclerosis; inflammation; AIDS; cancer therapy and cancer-associated pain; anxiety; sleep; anorexia; convulsions; and respiratory conditions including asthma.

Working with clinicians and other scientists, we are working on an interdisciplinary program for biomedical cannabis research to explore the full potential of cannabis and cannabinoids in human health and disease. For this, we will have a state-of-the-art inhalation facility. This is important, as the most common way to consume cannabis is through inhalation (of smoke or vaporized cannabis/cannabinoids). With this, we will be able to deliver inhaled cannabis and cannabis-derived cannabinoids/novel drugs in a real-world scenario- to assess efficacy in disease models and understand the immune-medicated mechanisms involved in the potential therapeutic benefits of cannabis.
