Summary
This project aims to engineer a naturally-occurring human protein, called an adnectin, to produce molecules that are able to bind specific targets in the human body, and as such may be used in the diagnosis and therapy of a range of diseases.
Throughout our lives cells must die and be replenished. One way multicellular organisms remove unwanted cells is through a process called programmed cell death. This process eliminates redundant, damaged or infected cells by a program of cell suicide. We are studying the underlying molecular mechanisms of this cell suicide in order to design new pharmaceuticals to treat illnesses caused by a disruption in programmed cell death. The fine balance between living and dying cells must be maintained a ....Throughout our lives cells must die and be replenished. One way multicellular organisms remove unwanted cells is through a process called programmed cell death. This process eliminates redundant, damaged or infected cells by a program of cell suicide. We are studying the underlying molecular mechanisms of this cell suicide in order to design new pharmaceuticals to treat illnesses caused by a disruption in programmed cell death. The fine balance between living and dying cells must be maintained and if this balance is lost then disease may result. A reduced level of cell death may result in cancers while too many dying can contribute to degenerative diseases such as Alzheimer's disease and stroke. Currently many of these diseases do not have effective treatments. We will determine the three-dimensional structures of key proteins involved in programmed cell death and use this information to design drugs that can interfere with the molecular processes involved in signalling cell death. Such drugs may prove useful new therapies in a wide range of diseases caused by a breakdown in the biochemical paths to cell death.Read moreRead less
Alzheimer's, Huntington's and Parkinson's diseases involve the formation of protein aggregates, termed amyloid. The formation of amyloid leads to cell death and neurodegeneration. The most important cellular events perturbed by the formation of amyloid aggregates are unclear. Recent evidence suggests that sterols (including cholesterol) have an important role in cellular toxicity. This study will examine the molecular basis for this, enhancing our understanding of the amyloid diseases and could ....Alzheimer's, Huntington's and Parkinson's diseases involve the formation of protein aggregates, termed amyloid.

Summary
Membrane trafficking, the topic of the 2013 Nobel prize in Medicine, is required for delivery of cellular cargo. This research will investigate the interactions and structures of proteins from the neuronal membrane trafficking system. Understanding how this system operates will expand our knowledge of processes fundamental to learning and memory and may ultimately lead to development of selective therapeutics for treating a range of diseases.
