Summary
Tissue-type plasminogen activator (t-PA) is used clinically to remove blood clots. Recently, a role for t-PA in the brain was discovered where under pathological conditions it can promote ischaemic and excitotoxic brain injury. This project will examine the mechanisms by which t-PA promotes injury to brain cells. It is anticipated that results obtained could be used to devise a means to reduce t-PA toxicity in the brain that would be of therapeutic benefit for patients with ischaemic stroke.

Summary
Phencyclidine is the best known pharmacological agent that can induce schizophrenia-like symptoms in humans and animals. Recent research has strongly suggested that neuregulin1 and ErbB4 signalling are involved in schizophrenia pathology. This study will be the first to determine whether neuregulin1 is altered by phencyclidine, which will further our knowledge by re-evaluating the causal role of neuregulin1 in schizophrenia.
A Novel Marker Of Distressed Neurons In The Hypoxic Brain: Regulation, Function And Potential Clinical Utility.

Summary
The brain is easily damaged by lack of oxygen (hypoxia). We have recently identified a novel protein called GLAST1b which is expressed in distressed neurons. This protein is a glutamate transporter. Glutamate is implicated as a toxic agent hypoxia. This study will investigate what regulates the expression of GLAST1b, what the consequences of expression are, and whether this marker can be developed as a diagnostic tool for identifying the presence of, and distribution of brain damage.
