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.

Summary
Alzheimer's disease (AD) prevalence is rising and there is currently no curative treatment. Production of neurotoxic amyloid-beta peptide (Abeta) in the brain is thought to be one causative factor in AD. We have recently discovered a new drug that alters lipid levels in cell membranes and potently inhibits Abeta production by neurons. We will define precisely how this drug works and examine its potential to reduce Abeta accumulation in the brains of mice genetically engineered to mimic AD.
The activation of T lymphocytes is essential part of our immune system to fend off harmful intruders. Our research aims to understand the process of T cell activation, in particular, the contribution of fats. We found that fats create a highly ordered patch at the T cell activation site. We want to understand how lipids and proteins work together to activate T cells, how this ordered regions function in T cell activation and whether dietary lipids alter these patches and thus T cell activation.
