Summary
Use of antibodies for cancer therapy, where a protein is made in the laboratory to recognize and act on cancer cells that have a target antigen, has emerged as an important therapeutic area in oncology. The lewis-y (Ley) antigen is found in over 70% of epithelial cancers. We have developed an antibody against Ley (hu3S193) which can target cancer cells. Our research is aimed at developing optimal cancer cell killing by our anti-Ley antibody.
This study aims to elucidate central pathways which can be manipulated to drive the storage of excess energy away from fat and instead directing it into the production of bone mass. Having identified leptin-responsive NPY neurons as important in the control of energy partitioning, we will focus on manipulating these neurons in the hypothalamus using innovative technology to alter body composition. This research has the potential to result in novel treatments for obesity and osteoporosis.

Summary
Ghrelin is a hormone that primarily targets the brain to increase food intake and body weight. It has evolved to prevent starvation during periods of negative energy balance by promoting energy intake and storage. We have identified central ghrelin resistance in diet-induced obesity (DIO) as a novel disturbed neuroendocrine system that restricts excessive food intake. Therefore, a novel approach to treat DIO is to exploit or enhance these intrinsic mechanisms that restrict the development of obe ....Ghrelin is a hormone that primarily targets the brain to increase food intake and body weight.

Summary
Insulin is known for its role in the regulation of glucose metabolism in the liver, muscle and fat, however very little is known about the role of insulin in the brain. This project aims to improve our understanding on how insulin regulates energy balance and appetite and identifies the exact neuronal networks involved in the brain and to understand the mechanistic insights into the pathology of obesity, providing the means for the development of more effective and safer therapeutic approaches.
The Role Of Brain Inflammation In Leptin Resistance

Summary
Melanocortin neurons control body weight and are regulated by leptin. In obesity leptin cannot regulate the melanocortin system. We will test if leptin action on melanocortin neurons is limited by increased expression of suppressor of cytokine signalling 3 (SOCS3) in obese mice. As an alternative we will test if there are changes in the blood brain barrier, or an increased density of support and immune cells around melanocortin neurons of obese mice that might restrict inputs to these neurons.
