Topic: Tau

Develop antibody-based approaches to Alzheimer’s disease at the Queensland Brain Institute. The project investigates tau-targeting monoclonal antibodies through protein production, cell-based experiments and mouse studies. Responsibilities include analysing results, preparing publications, contributing to funding applications and supporting junior researchers. This full-time appointment runs for up to 12 months, with an immediate start preferred. Annual base pay is AUD 85,373–113,660, plus 17% superannuation.

Intraneuronal accumulation of the microtubule associated protein Tau is largely recognized as an important toxic factor linked to neuronal cell death in Alzheimer’s disease and tauopathies. While there has been progress uncovering mechanisms leading to the formation of toxic Tau tangles, less is known about how intraneuronal Tau levels are regulated in health and disease. Here, I will discuss our recent work showing that the intracellular trafficking adaptor protein Numb is critical to control intraneuronal Tau levels. Inactivation of Numb in retinal ganglion cells increases monomeric and olig

Alzheimer’s Disease is characterised by the accumulation of misfolded proteins, namely amyloid and tau, however it is synapse loss which leads to the cognitive impairments associated with the disease. Many studies have focussed on single time points to determine the effects of pathology on synapses however this does not inform on the plasticity of the synapses, that is how they behave in vivo as the pathology progresses. Here we used in vivo two-photon microscopy to assess the temporal dynamics of axonal boutons and dendritic spines in mouse models of tauopathy[1] (rTg4510) and amyloidopathy[2

Tara Spires-Jones’ research focuses on the mechanisms and reversibility of neurodegeneration in Alzheimer’s disease, other degenerative brain diseases, and ageing. The objective of her research group is to understand why synapses and neurons become dysfunctional and die in these diseases in order to develop effective therapeutic strategies. Her work has shown that soluble forms of the pathological proteins amyloid beta and tau contribute to synapse degeneration, and that lowering levels of these proteins can prevent and reverse phenotypes in model systems. Further, she has pioneered high-reso

This seminar is part of our “Emergent Scientists” series, an initiative that provides a platform for scientists at the critical PhD/postdoc transition period to share their work with a broad audience and network. Summary: These talks cover Alzheimer’s disease (AD) research in both mice and humans. Christiana will discuss in particular the translational aspects of applying mouse work to humans and the importance of timing in disease pathology and intervention (e.g. timing between AD biomarkers vs. symptom onset, timing of therapy, etc.). Siddharth will discuss a rare variant of Alzheimer’s dise
