Summary
Diseases associated with exaggerated inflammation account for a large toll of human disease. We have recently described how mice with a mutation in the Sharpin gene, that causes the chronic proliferative dermatitis phenotype (cpdm), can be rescued by crossing these mice to TNF (Tumor Necrosis Factor) knock-out mice. Our findings suggest that TNF induced cell death, rather than TNF induced cytokine production, may be at the root of many inflammatory diseases and we aim to test this hypothesis in ....Diseases associated with exaggerated inflammation account for a large toll of human disease.

Inflammatory skin disorders, such as psoriasis and dermatitis, are responsible for a large burden of human disease and affect people across alldemographics. Knockout (KO) of TNF signalling members in mice is known to induce skin inflammation. This project proposes to use these genetic mouse models to investigate how and why disruption of particular TNF superfamily members leads to disease and potentially identify new targets for treatment.

Summary
Associate Professor Helen Thomas is a molecular and cell biologist with a particular interest in pancreatic islet biology, studying the mechanisms of pancreatic beta-cell destruction in diabetes. The aim of this work is to develop strategies to protect these cells. Such protection will improve our ability to preserve beta-cell mass in type 1 and type 2 diabetes, and after islet transplantation.
Cell death is a normal process that permits the growth and defense of our vital tissues. One kind of cell death, necroptosis, is characterised by the swelling and bursting of cells, triggering inflammation. Necroptosis is a key feature of illnesses ranging from colitis to arthritis, and contributes to the brain and heart damage that follows strokes and heart attacks. Understanding necroptotic cell death will pave the way for new therapies for those who suffer from these devastating conditions.
