The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

Neurons are highly compartmentalized cell-types. In neurodegenerative diseases such as Alzheimer's disease, the protein Tau that serves a distinct function in one cellular compartment (the axon) accumulates in a massively phosphorylated form elsewhere (somatodendritic compartments and their spines) which is believed to impair neuronal functions. We will investigate how Tau is distributed in health and disease, and determine how this distribution is regulated.
A New Function For An Old Enzyme: Src Protein Kinase Directs Excitotoxic Neuronal Death In Stroke

Summary
In our previous investigation of how brain cells die in patients suffering from stroke, we found that stroke causes aberrant activation of an enzyme called Src in the affected brain cells. Furthermore, this aberrantly activated Src directs the brain cells to undergo cell death. Our proposal, which aims to decipher this neurotoxic mechanism of the aberrantly activated Src will benefit development of new therapeutic strategies to reduce brain damage in stroke patients.
