Biography

Biography

Dr Patabendige is a postdoctoral research fellow with significant research expertise in cerebrovascular biology, and in particular, studying the blood-brain barrier (BBB, the specialised physiological barrier that protects the brain from blood-borne toxins and pathogens, and regulates molecular traffic between the blood and the brain) in health and disease. She received her PhD from King’s College London (University of London), UK under the mentorship of Prof Joan Abbott. During her PhD, she developed a porcine BBB model that mimics the in vivo BBB closely. This is one of the most robust and reproducible primary BBB models currently available, and is being used by many academics and pharmaceutical companies for drug screening and functional studies. Following her PhD, she spent a short period working with pharmaceutical industry partners before moving to the University of Liverpool, UK.

 Her postdoctoral research at Liverpool was focused on developing a human BBB model to study viral encephalitis. Here she used containment level 3 flaviviruses to investigate the mechanisms of neuroinvasion across the human BBB and the pro-inflammatory cytokine response on the brain endothelium. In 2012, Dr Patabendige was awarded one of the inaugural David Sainsbury Fellowships from the National Centre for the Replacement, Refinement and Reduction of Animals in Research (NC3Rs, UK) for early career researchers. The University of Liverpool awarded a Tenure-Track Fellow position to Dr Patabendige in 2014 recognising her potential of becoming a future research leader. Dr Patabendige relocated to Australia in 2014 to continue her fellowship with collaborators based in Melbourne. In 2016, recognising her expertise in BBB and cerebrovascular biology, Dr Patabendige was recruited to the Translational Stroke Research Group at the University of Newcastle, led by Prof Neil Spratt to head a laboratory team working on an NHMRC funded project on intracranial pressure (ICP) and hypothermia treatment for stroke. 

Current research interests

Investigating the mechanisms involved in the pathophysiology of impaired brain fluid homeostasis in neurological diseases such as stroke and brain trauma. Disruption of brain fluid dynamics can be life threatening, as this leads to an elevated ICP. Dr Patabendige’s current research within the Translational Stroke Research group involves the use of a range of preclinical and in vitro models of the BBB and blood-cerebrospinal fluid barrier (B-CSF-B; modelling the choroid plexus, where CSF is formed) to explore potential treatment strategies to reduce the ICP elevation post ischaemic stroke.

© 2014 by John Wiley & Sons, Inc. Cell culture models of the blood-brain barrier (BBB) are useful tools to study the functionality of the BBB in health and disease. Several good in vitro BBB models are available from different species. However, most brain endothelial cells lose some of their in vivo BBB phenotype in culture. Porcine brain endothelial cells (PBECs) tend to retain most of their in vivo BBB characteristics and usually give higher transendothelial electrical resistance (TEER, representing functional well-developed tight junctions) compared to brain endothelial cells from other species. The protocol described in this unit gives detailed instructions for isolation and culture of PBECs from fresh porcine brains. This porcine BBB model generates high TEER without the need for co-culture with astrocytes. However, astrocyte-derived factors can be introduced to the system through the use of astrocyte-conditioned medium or co-culture with astrocytes, which may be necessary for further enhancing the BBB phenotype for certain complex studies.

Neural signalling within the central nervous system (CNS) requires a highly controlled microenvironment. Cells at three key interfaces form barriers between the blood and the CNS: the blood-brain barrier (BBB), blood-CSF barrier and the arachnoid barrier. The BBB at the level of brain microvessel endothelium is the major site of blood-CNS exchange. The structure and function of the BBB is summarised, the physical barrier formed by the endothelial tight junctions, and the transport barrier resulting from membrane transporters and vesicular mechanisms. The roles of associated cells are outlined, especially the endfeet of astrocytic glial cells, and pericytes and microglia. The embryonic development of the BBB, and changes in pathology are described. The BBB is subject to short and long-term regulation, which may be disturbed in pathology. Any programme for drug discovery or delivery, to target or avoid the CNS, needs to consider the special features of the BBB. © 2009 Elsevier Inc. All rights reserved.
