Summary
Type III hypersensitivity underlies a number of common autoimmune diseases, including rheumatoid arthritis and lupus erythematosus. These diseases are caused by the deposition of immune complexes (IC) and the accumulation of neutrophils within small blood vessels. We will use real time imaging to dissect in space and time the recruitment of neutrophils and IC deposition during type III hypersensitivity reactions in order to better understand the pathogenesis of these conditions.

Summary
We aim to determine how viruses affect the cells they infect, In particular how they can alter the metabolism and balance of lipids in cells and how this impacts the bodies capability to respond immunologically. We believe that by understanding these basic principles we can target ares fr antiviral therapeutic potential.

Summary
Immuno-modulators utilize the patient’s own immune system to eliminate or slow the growth of cancerous cells. We have identified a novel immuno-modulator which could be a significant player in immune-modulation therapy for the treatment of cancer. We will use the development grant to develop a product which has significant potential to be the next generation treatment for cancer.
Specialised immune cells, called cytotoxic T cells, circulate through the body, and kill infected cells to protect us from disease. We discovered that a protein, DOCK8, is important for the regulation of T cell function. Importantly, humans with mutations in the DOCK8 gene suffer from a debilitating, and potentially lethal, immunodeficiency disease. This project will therefore elucidate the role of DOCK8 in immune cells, to better understand the consequences of DOCK8 deficiency for immunity.
Understanding the molecular mechanisms regulating neuronal fusion. Neurons are tightly connected individual cells that communicate through chemical and electrical signals, and this project aims to discover the key molecules that allow these cells to remain as individual units without fusing with each other. The nervous system, unlike other tissues, is made of discrete individual cells, connected by chemical and electrical synapses but not by cytoplasmic continuity. However, how this is achieved ....Understanding the molecular mechanisms regulating neuronal fusion. Neurons are tightly connected individual cells that communicate through chemical and electrical signals, and this project aims to discover the key molecules that allow these cells to remain as individual units without fusing with each other. The nervous system, unlike other tissues, is made of discrete individual cells, connected by chemical and electrical synapses but not by cytoplasmic continuity. However, how this is achieved and how neurons maintain their individuality during development, remodelling and ageing is unknown. The project aims to address this gap using a genetic approach and the nematode Caenorhabditis elegans as an experimental system. The results may provide insights into how the nervous system develops and functions.Read moreRead less
The Therapeutic Potential Of Neuroepithelial Cells In The Injured Rat Spinal Cord.

Summary
At present, human spinal cord injury is a permanent disease, as damaged cells (neurons) within the spinal cord are unable to regrow. Early in development, some species have the ability to regrow neurons across a damaged area. The cells that support this regrowth are unknown. These supportive cells could be an effective means of stimulating regrowth in the adult spinal cord. Our aim is to investigate the growth potential of rat embryonic spinal cord cells, for adult spinal cord cell regrowth.

Summary
Hematopoiesis, the processes of making blood cells, represents one of the best-defined paradigms for studying stem cell biology, but our understanding of how theses cells form in the embryo is incomplete.Our preliminary studies have revealed the existence of a novel "buddy cell" that directly regulates the induction of blood stem cells. This grant seeks to further these observations, and its general aim is to identify the molecular signals that the buddy cell uses to make blood stem cells
