Summary
Our recent work has discovered that the Nedd4 gene is crucial for the growth and development of blood vessels and lymphatic vessels. Our data suggest that Nedd4 controls vessel growth by regulating the levels and signalling activity of the key vascular growth factor receptors VEGFR-2 and VEGFR-3. The goals of this proposal are to define precisely how Nedd4-1 regulates the activity of these receptors and how VEGFR signalling could be better targeted to treat vascular disorders.
Sorting Out The Synapse: The Role Of Intracellular Trafficking In NMDA Receptor Homeostasis

Summary
When the normal levels of cell surface proteins in neurons are reduced this can lead to a variety of debilitating neurodegenerative and neuronal diseases. These levels are maintained by organelles inside the neuron called endosomes. In this project we will examine how cell surface receptors required for synapse formation are transported through endosomes by a protein machine called retromer, which is important in both Alzheimer’s and Parkinson’s disease.
