Research Summary

Little's research is focused on understanding how the metabolic disruptions that characterize type 2 diabetes affect cellular inflammation and explore how different exercise and nutritional strategies can be used to reduce inflammation and improve overall cardiometabolic health.

Biography

My interest in metabolism began as a competitive distance runner as I became fascinated with trying to understand how the body produced energy to fuel exercise. I was first introduced to research as an undergraduate summer student working in the laboratory of Dr. Martin Gibala at McMaster University and was quickly hooked. After pursuing an MSc degree at the University of Saskatchewan focusing on sport nutrition I returned to McMaster to complete my PhD focusing on muscle mitochondrial adaptations to exercise in healthy humans and individuals with type 2 diabetes. These experiences gave me a strong background in human exercise physiology and metabolism. In my postdoctoral fellowship at UBC I explored how metabolic disruptions associated with obesity and type 2 diabetes (e.g., high glucose, hyperlipidemia) impacted inflammatory activation of isolated cells. In my current lab we combine all of these approaches to understand how the metabolic disruptions that characterize type 2 diabetes affect cellular inflammation and explore how different exercise and nutritional strategies can be used to reduce inflammation and improve overall cardiometabolic health.

Research Interests & Projects

Obesity, insulin resistance (prediabetes), and type 2 diabetes are interrelated disorders characterized by progressively deteriorating metabolic health. Metabolic impairments in these conditions lead to many negative health consequences, including chronic low-grade inflammation and increased risk of cardiovascular disease. Research in the Exercise Metabolism and Inflammation Laboratory (EMIL) is focused on: 1) Optimizing exercise and nutritional strategies to prevent, treat and reverse type 2 diabetes; and 2) Understanding how exercise, diet, and metabolic disruptions impact immune cell function.

We utilize a translational approach, where in vivo studies and clinical trials in humans with type 2 diabetes guide cell culture experiments designed to understand molecular mechanisms, and vice versa.

In our human physiology laboratory located in the Arts Building we have a metabolic cart, vascular ultrasound equipment, treadmill, cycle ergometers, elliptical trainer, resistance training equipment, and a medical procedures area which enable us to conduct studies ranging from acute exercise and nutritional manipulations to clinical exercise trials with metabolic measurements.

In our cellular and molecular laboratory located in the Reichwald Health Sciences Centre, we have additional clinical testing space to collect blood samples and perform acute exercise and nutritional studies with adjacent cell culture suite, flow cytometer, MagPIX(R) multiplex reader, MSD Quickplex reader, real-time PCR machine, multi-function plate reader, and western blot equipment.

Key experimental techniques utilized include continuous glucose monitoring, flow-mediated dilation, whole blood cultures, immune cell isolation/culture, and multi-colour flow cytometry. Current nutrition interests include low-carbohydrate diets and nutritional ketosis, whereas exercise studies are focused on high-intensity interval training and exercise “snacks”.

At the undergraduate level, I teach HMKN 313 – Exercise Metabolism and supervise students in HMKN 499 Research Practicum.
