Dr Jenna Ziebell is a lecturer in the Wicking Dementia Research and Education Centre. Her research interests revolve around the role of microglia in health, ageing and disease. Dr Ziebell has a strong interest in traumatic brain injury, and priming of the immune system with ageing.


Dr Ziebell has a long-standing interest in the role of inflammation in neurological diseases, particularly the role of microglia (the immune cells of the central nervous system). She is a mid-career researcher who recently returned to Australia from the Translational Neurotrauma Program in Phoenix, AZ, USA; where she led a research team that investigated the role of microglia in acute neurological diseases. Her interest in the role of microglia in health and disease was ignited during her PhD at Monash University and has continued throughout postdoctoral research at the University of Adelaide (2009-2011), University of Kentucky (2012), USA, and University of Arizona/Phoenix Children’s Hospital (2012-2015). Dr Ziebell’s areas of interest include microglial activation in health and disease, trauma and injury related circuitry rearrangements, microglial priming and senescence in ageing and dementia. Therapeutically, she has interests in pharmacological interventions to manipulate microglial response to injury and disease.

Research Themes

Dr Ziebell’s research aligns to the University’s Better Health research theme. Her research interests include experimental models of neurological disease including traumatic brain injury and dementia. Dr Ziebell’s research primarily focuses on the inflammatory cascades initiated in these diseases and how this influences disease progression, neuronal circuits, as well as cognition and motor function.

Could gut microbiota influence cognitive decline and Alzheimer's disease? (2018)$0
This pilot grant will map gut microbiota in three populations:A) Individuals with a clinical diagnosis of dementia: Individuals identified by a clinician as living with dementia will be recruited (n=20). These individuals must be residing in the community as gut microbiota alterations are known to be dependent on the environment (13).B) Spousal caregivers for those living with dementia: Carers of individuals living with dementia are six times more likely to develop dementia (14). Stress is a leading theory for this occurrence, however shared gut microbiota is a potential unexplored link. This group potentially represents the pre-clinical population where alterations to gut microbiota are occurring before symptoms are established (n=20).C) Spousal caregivers providing informal care to someone who does not have dementia: A cohort of individuals providing care to a spouse living with a chronic illness will be recruited (n=20). This group will provide evidence as to whether the disease and/or gut microbiota influence AD development.By determining the gut microbiota diversity in these populations, we will begin to understand whether gut microbiota influences cognitive decline and dementia. Initially this will be a cross-sectional study but if data are promising then it will lead to a longitudinal study.

Can microglia priming influence neurodegeneration? (2018)$10,000
Inflammation has been implicated in premature ageing of the brain and the development of neurological disease (1). Microglia are the inflammatory cells of the brain, and currently it is unclear whether they are active (driving pathology) or passive (a bystander) in the ageing and neurodegenerative processes. In response to disturbances in the microenvironment microglia are capable of secreting both pro- and anti-inflammatory cytokines to restore homeostasis. With subsequent disturbances, microglia mount an exaggerated response, due to priming. Increasing age impedes microglias ability to perform the most essential of homeostatic functions. At this time microglia are known as dystrophic; stuck in a pro-inflammatory phenotype. Understanding this switch to a pro-inflammatory state may aid in preventing the effects of ageing through modulation of microglial activity and offers a novel target for therapy to slow the progression of neurological disease. For this to be effective, we must first define the precise roles of microglia in ageing and neurodegeneration. By determining microglial phenotype throughout disease progression we can gain insight into their role in disease pathology.

How do microglia-synapse dynamics change with Alzheimer's disease? (2017)$50,000
This project explores the emerging role of microglia in facilitating changes to neuronal connections, synaptic plasticity or the ability of the brain to remodel throughout the lifespan in response to a changing environment. Using state of the art imaging techniques, this project will explore microglia-synapse interactions in real time, to elucidate the role microglia play in synaptic plasticty in Alzheimer's disease and throughout ageing.
