Identification of novel antigens for vaccination and immunotherapy against the human gastric pathogen, Helicobacter pylori. The bacterium Helicobacter pylori is a significant human pathogen which infects the stomach where it is the major cause of stomach and duodenal ulcers, plus two types of cancer. This project proposes to utilise a novel strategy to identify potential vaccine targets on the bacterial surface with the aim to develop an effective vaccine against this organism. Such a vaccine wo ....Identification of novel antigens for vaccination and immunotherapy against the human gastric pathogen, Helicobacter pylori. The bacterium Helicobacter pylori is a significant human pathogen which infects the stomach where it is the major cause of stomach and duodenal ulcers, plus two types of cancer. This project proposes to utilise a novel strategy to identify potential vaccine targets on the bacterial surface with the aim to develop an effective vaccine against this organism. Such a vaccine would protect against the development of stomach cancer, hence saving lives, plus significantly reduce the incidence of stomach ulcers, thereby reducing suffering of individuals and providing financial benefits to employers.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
Reg growth factors in gastric regeneration and disease. This project will obtain a more detailed knowledge of the role that growth factors play in helping the lining of the stomach repair itself after damage caused by disease. Growth factors may also play a role in causing stomach cancer. To do this we will examine the expression of growth factors in number of stomach diseases and cancer and assay the ability of growth factors to promote the growth of stomach cells.
This work is that it will co ....Reg growth factors in gastric regeneration and disease. This project will obtain a more detailed knowledge of the role that growth factors play in helping the lining of the stomach repair itself after damage caused by disease. Growth factors may also play a role in causing stomach cancer. To do this we will examine the expression of growth factors in number of stomach diseases and cancer and assay the ability of growth factors to promote the growth of stomach cells.
This work is that it will contribute to our knowledge of how cell growth in the stomach is controlled under normal circumstances and in the very common pathological conditions of tissue damage, inflammation and cancer. It may also help us understand how inflammation can in some circumstances lead to cancer.Read moreRead less

Summary
Understanding interactions between gut epithelial stem cells and neurons. This project aims to investigate the interaction between gut neurons and the epithelial stem cell compartment, as well as the relationship between age-related loss of enteric neurons and changes in gut epithelial stem cells. This project will include novel co-culturing of organoids and enteric neurospheres, which will identify mechanisms by which nerves influence the epithelia. The outcome of the project will be a better u ....Understanding interactions between gut epithelial stem cells and neurons. This project aims to investigate the interaction between gut neurons and the epithelial stem cell compartment, as well as the relationship between age-related loss of enteric neurons and changes in gut epithelial stem cells. This project will include novel co-culturing of organoids and enteric neurospheres, which will identify mechanisms by which nerves influence the epithelia. The outcome of the project will be a better understanding of the biology of the body’s most highly proliferative, long-lived stem cells, intestinal epithelial stem cells. This could have significant long term impact on the quality of life in an ageing population.Read moreRead less

Functional insights into the roles of enteric glia. This project aims to review our current definition of enteric glia populations, and our understanding of their communication mechanisms in the mouse and primate colon. It will generate new knowledge of enteric glia biology using advanced microscopy and image analysis. Calcium imaging and novel biosensors will measure cell signalling in enteric glia. It will provide the most comprehensive analysis of glia connectivity, morphology and receptor ex ....Functional insights into the roles of enteric glia.

It will generate new knowledge of enteric glia biology using advanced microscopy and image analysis. Calcium imaging and novel biosensors will measure cell signalling in enteric glia. It will provide the most comprehensive analysis of glia connectivity, morphology and receptor expression in the primate colon. Expected outcomes include a detailed map of enteric glia and definitions of their basic biology. This project builds on the techniques and collaborations made by the candidate over recent years. This will benefit our basic understanding of enteric glia biology.Read moreRead less
