Saving your skin: physiology of immune regulation in mammalian lymph nodes. The overall aim of this proposal is to understand the mechanisms through which a rare population of regulatory cells maintains skin integrity. Despite their importance, little is known about the regulatory pathways these cells utilise. Previous work from the team has described an innovative technique to enrich these cells for in-depth study and demonstrated their potent regulatory capacity in vivo. This project will enha ....Saving your skin: physiology of immune regulation in mammalian lymph nodes. The overall aim of this proposal is to understand the mechanisms through which a rare population of regulatory cells maintains skin integrity. Despite their importance, little is known about the regulatory pathways these cells utilise. Previous work from the team has described an innovative technique to enrich these cells for in-depth study and demonstrated their potent regulatory capacity in vivo. This project will enhance our understanding of these cells and uncover their mechanisms of action. The outcomes of this work will therefore provide fundamental new knowledge of skin physiology, and lead to novel insights regarding how healthy skin, which is essential for the very survival and function of a living organism, may be maintained.Read moreRead less
Defining how serotonin regulates gut motility. This project aims to deepen knowledge of gastrointestinal physiology, and reveal the mechanisms by which the major gastrointestinal signalling molecule, serotonin, regulates gut peristalsis. Almost all of the serotonin in our body is made in the gastrointestinal tract where it controls many functions, including how our gut wall contracts during peristalsis. Proper control of gut peristalsis and the transit of material through our bowel is important ....Defining how serotonin regulates gut motility. This project aims to deepen knowledge of gastrointestinal physiology, and reveal the mechanisms by which the major gastrointestinal signalling molecule, serotonin, regulates gut peristalsis. Almost all of the serotonin in our body is made in the gastrointestinal tract where it controls many functions, including how our gut wall contracts during peristalsis. Proper control of gut peristalsis and the transit of material through our bowel is important for our health. This project expects to define how serotonin controls peristalsis, where in the bowel this serotonin comes from, how serotonin communicates with the nervous system in our gastrointestinal tract, and how the cells that synthesise gut serotonin respond to contraction to trigger the secretion of serotonin.Read moreRead less
Neurons and neurotransmitters that control the apnoeic response to irritation of the larynx. Normal function of the larynx enables breathing, cough, singing, speech and many other normal functions. This project will reveal how nerves in the brain coordinate to achieve these many functions; in particular the way that breathing stops if fluid or smoke enters the larynx.
Nutritional and bacterial influences on gut and peripheral homeostasis. Nutritional and bacterial influences on gut and peripheral homeostasis. This project aims to understand the role of macronutrients on gut homeostasis. While the understanding of what factors affect gut homeostasis is still in its infancy, scientists know that its disruption contributes to a broad range of inflammatory diseases, including type 1 diabetes and asthma.

Nutritional and bacterial influences on gut and peripheral homeostasis. This project aims to understand the role of macronutrients on gut homeostasis. While the understanding of what factors affect gut homeostasis is still in its infancy, scientists know that its disruption contributes to a broad range of inflammatory diseases, including type 1 diabetes and asthma. This project will determine the role of specific macronutrients on gut microbiota, gut epithelium, and immunity in mice, and the receptors involved. This research could ultimately lead to significant decreases in the cost of healthcare.Read moreRead less

Unified framework of intestinal motility. The project aims to establish how a few fundamental mechanisms determine the large repertoire of intestinal motor patterns responsible for moving nutrients along the digestive tract. The project will combine experimental and theoretical data, with biomechanical and electrophysiological models to create a new understanding of this essential function of the body.
The comparative physiology of oxygen delivery to the kidney. The kidney is in danger of hyperoxia because the kidney receives so much blood relative to its mass. It is proposed that shunting oxygen between arteries and veins substantially mitigates the risk of hyperoxia, but under certain circumstances shunting substantially increases the risk of kidney hypoxia. Using a combination of synchrotron and histological imaging, This project will carefully define the three-dimensional vasculature of th ....The comparative physiology of oxygen delivery to the kidney. The kidney is in danger of hyperoxia because the kidney receives so much blood relative to its mass. It is proposed that shunting oxygen between arteries and veins substantially mitigates the risk of hyperoxia, but under certain circumstances shunting substantially increases the risk of kidney hypoxia. Using a combination of synchrotron and histological imaging, This project will carefully define the three-dimensional vasculature of the renal cortex in several different species and interpret its functional significance using computational modeling. The outcome of this project will be a new understanding in the comparative physiology of oxygen transport and shunting in the kidney.Read moreRead less

This project aims to understand how the heart and blood vessels evolved in mammals, birds, reptiles and fish to achieve efficiency. The heart is the most important organ for life. The project will study the structure and function of vertebrate animals’ hollow and spongy hearts to show how energetics shaped their evolution. It will measure arterial holes in bone to gauge brain and bone metabolism, which opens up a new way to measure metabolism in extinct animals directly from fossils, rather than by inference from living relatives. The expected outcome is to correlate cardiovascular design and metabolic rates of organs.Read moreRead less
