Summary
An estimated 415 million people world-wide were diagnosed with diabetes in 2015. One of the causal factors in disease is the dysregulation of insulin secretion. We have developed new techniques to study insulin secretion that has led us to propose a new model for secretory control. This proposal sets out experiments to critically test this model. The outcomes could have wide-reaching impact on understanding and for future treatment and prevention of the diabetes.
The Structure And Function Of The Apical Domain In Insulin Secreting Beta Cells.

Summary
Loss of control of insulin secretion is causal in diabetes and therefore its understanding is a key goal to shed light on the disease. We have recently identified a new domain in the insulin secreting cells, called the apical domain. This proposal will define the role of this apical domain in controlling insulin secretion. The outcomes could provide new insights into how diabetes develops and new targets for therapies.
Overcoming Therapeutic Resistance In Pancreatic Cancer

Summary
Pancreatic cancers arise when abnormal cells grow out from otherwise normal tissue. The resulting tumours contain a number of different types of cells, some of which help the tumour to grow, and some of which fight the tumour. We are interested in understanding how soluble molecules called cytokines influence the cells that promote tumour growth and metastasis. In particular, we will test whether cytokine inhibitors can overcome tumour resistance to chemotherapy.
Regulation Of Interleukin-1? Activation In Inflammatory Diseases

Summary
IL-1? protein is required to combat infection but also contributes to inflammatory diseases, such as Rheumatoid arthritis and diabetes. Understanding how IL-1? is produced is therefore critical to the development of better therapeutics for these conditions. We have identified a new pathway involving the protein RIP3 that can cause IL-1? activation. This project will examine how this pathway is molecularly regulated and determine its importance in inflammatory disease models.
