Associate Professor Brad Sutherland is an NHMRC Boosting Dementia Fellow in the Discipline of Medical Sciences, Tasmanian School of Medicine in the College of Health and Medicine. His main research interests focus on the regulation of the microvascular system, how it is controlled at the cellular and molecular level, and how this becomes dysfunctional in diseases such as stroke and dementia. He also teaches Neuroscience and Physiology into a number of units as part of the BMedRes degree.
Biography
Brad completed his PhD at the University of Otago (Dunedin, New Zealand) where he investigated the activation of inflammatory pathways in the brain after stroke. After a small stint as a Teaching Fellow in Pharmacology & Toxicology (University of Otago), he took up a Post-doctoral Research Fellowship with the Acute Stroke Programme, Radcliffe Department of Medicine, University of Oxford (Oxford, UK). During his time in Oxford, he formed an interest in the regulation of blood flow in the brain in health and disease. This led to studies investigating the interaction between brain tissue and the blood vessels, the signalling mechanisms that controlled energy delivery to the brain, and how these were disrupted in conditions such as stroke.
In mid-2016, Brad arrived at the University of Tasmania to continue his research into cerebral blood flow and brain diseases such as stroke and dementia. He continues to use a wide range of in vitro and in vivo models to assess mechanisms of neurovascular regulation and models of disease.

Expertise
Over many years, Brad has developed skills in a range of techniques to investigate blood flow in the brain, and to perform in vitro and in vivo experiments. Specifically, he has experience with multiple stroke models including intraluminal filament middle cerebral artery occlusion (MCAO) model and hypoxia-ischaemia model. He also uses in vitro models of stroke on primary cells or cell lines in culture by exposing cells to oxygen and glucose deprivation. He uses a number of transgenic mouse lines to answer biological questions and employs a range of techniques including light, epifluorescence, confocal and two-photon microscopy, immunohistochemistry, histology, molecular biology, and animal behaviour. He also has experience with animal MRI. These techniques can be utilised to investigate the biological basis of a range of neurological disorders.
Research Themes
Brad’s research aligns to the University’s research theme of Better Health. His research interests include understanding how blood flow is regulated in the brain, identifying how vascular dysfunction can lead to multiple brain diseases such as stroke, dementia and other neurodegenerative diseases. He also focuses on the discovery of novel therapeutic targets that can prevent vascular dysfunction to stop disease progression in the brain. He utilises a wide range of in vitro and in vivo models to assess brain function and brain disease.
Blood flow in the brain is controlled by the neurovascular unit, which is a complex interplay of cells that communicate in order to increase blood - and therefore energy – supply in areas where brain activity is occurring. This is a tightly coupled process that uses complex paracrine signalling mechanisms and is prone to injury in disease. Brad is currently investigating the role of multiple cell types in the neurovascular unit and the mechanisms by which neurovascular dysfunction can occur.
Recently, Brad has developed an interest in the microcirculation, specifically a cell type called pericytes which exclusively reside on capillaries. These cells are involved in many brain processes including regulating blood flow in the brain and maintenance of the blood-brain barrier and may contribute to injury and repair of a number of diseases. Brad’s ongoing studies are examining mechanisms of pericyte dysfunction following stroke and dementia.

Checking the pulse of pericytes: Do microglia cause a breakdown of brain blood vessels in Alzheimer's disease? (2024 - 2027)$1,278,438
- Description
- Pericytes are cells that control blood flow through capillaries. Microglia in the brain respond to inflammation. Some microglia interact with pericytes which may control blood flow and brain function. In Alzheimers disease (AD), this interaction is disrupted. This proposal will use innovative techniques to understand how pericytes and microglia interact and how this goes wrong in AD. This opens up new potential treatment options for AD.

Targeting no-reflow to augment tissue salvage in stroke (2022 - 2024)$999,978
- Description
- Ischemic stroke is due to a blocked major brain artery. Half of patients who receive acute treatment do not improve forunclear reasons. We will study one potential reason, the "no-reflow phenomenon", where micro-blockages in small vessels stop blood reaching thebrain despite unblocking the major artery. We will test how to reduce no-reflow in mice, and how it affects humans. Our ultimate aim is to develop aclinical trial for no-reflow to help brain tissue receive blood more efficiently.

Can metformin and exenatide improve brain vascular function in type 2 diabetes to reduce stroke severity? (2022)$68,581
- Description
- People with type 2 diabetes are four times more likely to have a stroke. As well as this, data shows that diabetic individuals who have a stroke are more likely to have a more severe stroke and are far more likely to die following a stroke. The primary treatment for stroke is to remove the clot that caused the stroke in the first place so that blood flow is restored to the affected area. Commonly prescribed anti-diabetic drugs appear to reduce diabetic stroke severity and improve patient outcomes following a stroke independently of lowering blood glucose levels, but we don't know how or why this is the case. The current project will determine whether common anti-diabetic drugs, metformin and/or glucagon like peptide 1 (GLP-1) receptor agonists such as exenatide, improve the health and function of blood vessels in the diabetic brain to reduce the impact of stroke. If true, this work will demonstrate that metformin and exenatide treatment may not only be useful for lowering blood glucose levels, but also aid in reducing the burden of stroke in those with type 2 diabetes.

A new theory of fatigue: The role of AgRP neurons in ME/CFS (2021 - 2023)$268,200
- Description
- Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a complex multi-system disease for which there is no cure. It is often characterised by fatigue, post-exertional malaise, cognitive dysfunction, muscle weakness, slowed reflexes and coordination, sleep disturbances, fever, myalgia, photosensitivity and neuro-immuno-endocrine dysfunction1 which can be disabling and dramatically impact quality of life. Some 190-240,000 Australians have been diagnosed with ME/CFS with many more probably undiagnosed.The fatigue experienced by patients with ME/CFS shares many features with the fatigue experienced in other conditions ranging from severe infections through cancer and brain injury to autoimmune diseases. Often the fatigue is overlooked by the medical profession and researchers alike. Never-the-less it is estimated that 38% of adults are affected by fatigue at some stage. Importantly for many, like patients with ME/CFS, there is no identifiable underlying pathology to blame and when there is a known pathology, the fatigue does not usually resolve with treatment of that pathology. We believe that fatigue is caused by an independent pathological process that can be triggered by many disease stimuli and can perpetuate independently of an associated trigger. We propose an overarching mechanism for all-cause fatigue driven by protective energy homeostasis mechanisms driven by neurons in the arcuate nucleus of the hypothalamus. These Agouti-related protein (AgRP) expressing neurons, occupy an unusual niche in the brain. They are well known for their role in regulating energy balance, but they also interact with the stress, anxiety, circadian and inflammation regulatory pathways of the hypothalamic-pituitary axis which are already known for participation in the pathology of fatigue. Importantly they are not protected by a structure called the blood-brain-barrier so are readily damaged by circulating inflammatory and stress stimuli. Moreover, they can be killed by such stimuli but also have the capacity to be replenished over time. These features make them good candidates to underpin the pathology of fatigue. We hypothesise that ME/CFS manifests when AgRP neuron signalling is impaired, resulting in a loss of homeostatic drive to promote arousal, attention and activity. We further hypothesise that restoration or replacement of AgRP neuron signalling will treat ME/CFS.We will test these hypotheses using transgenic mice developed by our multidisciplinary team that allow us to genetically control the activity of AgRP neurons and the regulation of the blood-brain-barrier and determine how they respond to inflammatory stimuli commonly used to generate animal models of ME/CFS-related fatigue. By examining how these animals then respond to drugs that change either the activity or the number of AgRP neurons, we will be able to determine whether this mechanism can be targeted to treat fatigue. If successful, these later proof-of-principle interventions may provide translatable therapies in their own right but are expected to pave the way for more refined medicinal chemistry.While the primary target of this research is finding a therapy that benefits patients with ME/CFS, our hypothesis is applicable to all forms of fatigue, whether associated with cancer, brain injury, autoimmune disease or severe infection. Importantly, while repopulation of lost AgRP neurons will take time, pharmacological mimicking of their function should produce immediate benefit. To the best of our knowledge, this is the first study world-wide to propose that fatigue is mediated by AgRP neuron signalling.

Posthuman Genetic Legacies (2021)$21,100
- Description
- Posthuman Genetic Legacies is a practice-led research project that investigates avenues of producing an alternative (non-human) andongoing genetic legacy via biotechnological intervention. The study draws on established practices in biological art to consider the feminist potential of cell culture and genetic engineering technologies to acquire biological offspring when conventional reproductive pathways are compromised or traditional conceptions of motherhood are undesirable. The project also aims to test the proposition that posthuman and new materialist philosophies, that disrupt binary categorisation and a human centred perspective, may offer a conceptual space for rethinking the anguish of situational childlessness. Through a range of boundary-challenging artistic examinations, existing regulatory and ethical issues will be examined to highlight the legal frameworks that govern access to reproductive technologies as well as ownership, use and patenting of biological material.

Is the neurovascular niche the initiation point for multiple sclerosis? (2021 - 2023)$240,000
- Description
- At present little is known about the cause of MS. This project aims to identify cellular changes that could explain some of the known risk factors and their contribution to MS pathology, and has the potential to identify cellular targets that could be used to develop tools for the early diagnosis and even prevention of MS. The specific cellular changes we are focusing on are pericytes (vascular cells only on capillaries) and oligodendrocyte precursor cells (cells that give rise to oligodendrocytes which myelinate axons in the brain).

Harnessing the dual roles of pericytes to improve stroke outcomes (2021 - 2024)$862,943
- Description
- Pericytes are cells that exclusively reside on capillaries and can actively contract or relax to modulate capillary blood flow. Pericytes also have angiogenic, stem cell and phagocytic properties that are important for brain function. In ischaemic stroke, when brain blood flow is depleted, pericytes contract and then die, leading to capillary constriction even after arterial blood flow has been restored. However, after the acute stroke period, pericytes may have an important role in brain repair. Therefore, limiting pericyte contraction acutely while promoting pericyte activity during recovery may be a novel therapeutic strategy for ischaemic stroke.Aim 1 will determine whether acute pericyte constriction of capillaries is implicated in worsening stroke outcome. We will utilise our available NG2-DsRed and PDGFRβ-Cre transgenic mouse lines to selectively kill (ablate) pericytes during acute period post-stroke while using our novel contrast-enhanced ultrasound paradigm to assess blood flow and stroke outcomes. In addition, we will use primary cell culture methods to analyse the secretome of neurons, astrocytes, microglia and endothelial cells following ischaemia and their effects on pericyte function.Aim 2 will investigate whether pericytes drive the recovery process of the brain following stroke. Through our aforementioned transgenic mouse lines, we will selectively ablate pericytes in the recovery phase to determine its influence on stroke outcome. We will use lineage tracing to track pericytes following stroke to determine whether pericytes migrate away from capillaries and differentiate into other cell types. Lastly, we will implant pericytes into the mouse brain post-stroke to promote recovery of the brain.This research will develop pericytes as a therapeutic target for both the acute and recovery phases of stroke, pioneering future ischaemic stroke treatment and providing novel approaches for other vascular diseases and brain injuries.

The role of the placenta in determining the post-natal effects of in utero exposure to bushfire smoke (2021)$20,000
- Description
- There is a growing body of evidence that in utero exposure to pollution events, such as bushfires, can have consequences for somatic, lung and immune development leading to an increased risk of lung disease later in life. However, there is a critical gap in the field that needs to be addressed - what is the mechanism linking in utero exposure to altered post-natal respiratory health? In novel preliminary experiments, we have data to suggest that altered placental function is the key. We hypothesise that impaired lung and immune development as a result of in utero exposure to landscape fire-derived particulate matter (PM) is due to alterations in placental structure and function. We aim to characterise the placental response to maternal exposure to bushfire smoke using samples from human placentas collected before, during and after the severe Tasmanian bushfires that occurred in the summer of 2018/19.

Differentiation of inducible pluripotent stem cells (iPSC) into pericytes to investigate neuron-pericyte interactions (2019)$9,980
- Description
- iPSCs can be differentiated into multiple cell types, including neurons and pericytes. We wish to differentiate iPSCs from the same parental lineage into pericytes, a vascular cell with roles in blood-brain barrier maintenance and regulation of cerebral blood flow. The interaction between pericytes and neurons has not been extensively studied, and these models will allow the determination of how these cells interact leading to novel research with relevance to understanding normal brain function and how this contributes to neurodegenerative diseases.

The role of skeletal muscle pericytes in the development of insulin resistance: friend of foe? (2019)$16,457
- Description
- An important action of insulin in the body is to increase blood flow through capillaries in skeletal muscles. This vascular action of insulin occurs rapidly after insulin levels in the blood rise, for example following a meal, to ensure that both insulin and glucose are delivered to muscle cells to enable glucose removal from the blood. Importantly, the vascular action of insulin is lost early in development of insulin resistance and contributes to the progression of the disease. Where and how insulin acts in the vascular tree to increase muscle blood flow remains poorly understood, with insulin's potential direct effects on capillaries completely overlooked. The proposed NHMRC Ideas grant will seek to fill this gap in knowledge by demonstrating that insulin acts directly on pericytes, a contractile cell type that wrap around capillaries, to increase capillary blood flow and that these effects are lost during insulin resistance and type 2 diabetes.

An energy crisis for Alzheimer's disease: is pericyte degeneration to blame? (2019 - 2022)$857,283
- Description
- One possible cause of Alzheimer's disease (AD) is narrowing of small blood vessels (capillaries) within the brain, limiting blood flow and energy supply. Pericytes, a cell found only on capillaries, maintain blood flow throughout the brain. In AD, pericytes may die leading to an energy deficit and memory problems. We will test using human brains and animal models whether pericyte loss causes AD and how this is happening. Pericytes could provide a new therapy option for AD.

- Description
- This collaboration will be between imaging neuroscientists based in the Wicking DementiaResearch and Education Centre (Canty, Bennett) and a cerebral vascular biologist based inthe School of Medicine (Sutherland). This work will take two different areas of biologicalresearch, our blood vessels and our brains, and investigate how reduced blood flow caninfluence neurons within our brains after an ischemic event typical of vascular dementia.This collaboration will run across two divisions of the College of Health and Medicine: theSchool of Medicine and the Wicking Dementia Centre and include staff at different levels(D/C/B). This collaboration aligns with the University subtheme of complex disease, underthe umbrella of Better Health - investigating the complexity of mixed dementia and linking itwith cardiovascular health. Dementia is a recognised flagship of the College of Health andMedicine, and this project aims to initiate a new area of research in vascular dementia,capitalising on existing researcher strengths. Alison Canty and Brad Sutherland are leaders intheir respective fields of expertise, and seek to work together on this innovative project toestablish a new line of enquiry to determine the origins of the pathology of vasculardementia. If funded, and if successful, we would aim to recruit a HDR student to continuethis work, providing a valuable training opportunity

Can anti-diabetic agents improve blood flow and outcome following stroke in type 2 diabetes? (2018)$24,912
- Description
- People with type 2 diabetes are four times more likely to have a stroke. Interestingly, common anti-diabetic drugs seem to improve patient outcomes following a stroke. This project will determine whether anti-diabetic drugs improve brain blood flow dynamics during and after stroke to reduce stroke severity in an animal model of type 2 diabetes.

Pericyte dysfunction limiting energy supply in Alzheimer's disease (2018 - 2021)$717,709
- Description
- Pericytes are contractile cells exclusively residing on the basement membrane of capillaries. These cells have been shown to control cerebralblood flow and energy supply, maintain the blood-brain barrier (BBB) and mediate beta amyloid clearance. An emerging pathologicalmechanism of Alzheimer's disease (AD) is the development of vascular dysfunction leading to chronic hypoperfusion, disruption of the BBBand altered beta amyloid clearance. These symptoms are all, in part, controlled by pericytes. Therefore, the degeneration of pericytes may becritical to the development of AD and could represent a novel cellular target for AD therapy. I will utilise my strong background in pericyte andneurovascular biology to:1) Establish a link between pericyte loss and human AD pathology. I will use human post-mortem brains and immunohistochemicaltechniques to assess pericyte degradation and its association with cognitive loss as well as amyloid, tau and vascular pathology.2) Follow changes in pericyte number, coverage and function alongside the development of AD. I will use NG2-DsRed mice that havefluorescent pericytes crossed with an animal model of AD to observe how pericytes change by assessing BBB function and capillary blood flowas AD pathology develops.3) Modulate blood flow and pericyte function directly in NG2-DsRed mice to associate pericyte dysfunction with changes in cognitivebehaviour and AD progression.4) Determine the mechanism of pericyte loss in AD using human pericyte cultures and identify novel compounds that could prevent pericyte degradation and cognitive decline.This research will provide an understanding of the importance of pericyte degeneration to AD pathology and whether pericytes represent a viable target on which further pre-clinical development of pericyte-targeting drugs for AD can begin.

Blood-brain barrier energy dysfunction: the unifying cause of fatigue (2017)$99,874
- Description
- Fatigue can be much more than just a sense of tiredness. It is also a debilitating symptom of many diseases and disorders, hampering peoples' ability to perform the simplest of daily activities. The underlying mechanism of fatigue is unknown. We hypothesise that fatigue is ultimately the result of reduced delivery of energy to the brain. We will assess how energy supply is altered in fatigued brain. A special diet (that supplies an alternative energy source for the brain) will be used to circumvent this energy deficit. We hope to establish how fatigue occurs and offer clues to a simple treatment strategy.

Paving the way for future stroke drug development: creating a new gold-standard model of stroke (2017 - 2019)$442,570
- Description
- Stroke is a leading cause of death and chronic disability. Stroke therapeutics developed in animal models fail when translated into human clinical trials, due to flaws inherent in these models. We will break through this translational roadblock by using magnetic microparticles to induce an ischemic stroke that accurately represents human disease
