Background

I am a Professor of Neurodegeneration for the Faculty of Medical Sciences at Newcastle University. My areas of expertise are protein misfolding, Parkinson's disease, Alzheimer's disease, alpha-synuclein, tau and amyloid-beta.

Research Focus

My research interests are focused on understanding the molecular basis of protein misfolding diseases using a variety of model organisms, from yeast to mice and rats. Our primary focus is on the molecular basis of neurodegenerative disorders. My team has developed key tools and assays for the study of protein-protein interactions that are at the root of protein aggregation, a key event in neurodegeneration. We are now using human brain tissue to investigate molecular signatures associated with disease, to translate our findings into laboratory model systems where we can test novel strategies for therapeutic intervention.

Research Interests and Contributions

1. Yeast as a model to define the molecular basis of neurodegeneration. I started my scientific career at the University of Leeds, studying the yeast vacuolar ATPase complex. This training was very useful and enabled me to then undertake an ambitious project during my PhD, where I developed the first yeast model of synucleinopathies. This was published in a landmark paper, in Science. Since then, I have continued to use yeast as a toolbox to investigate the basic molecular mechanisms associated with neurodegeneration in Parkinson’s and Huntington’s diseases. In particular, we have recently studied the effect of posttranslational modifications on alpha-synuclein aggregation and toxicity in yeast. Some representative publications include:

a.     Outeiro TF, Lindquist S. Yeast cells provide insight into alpha-synuclein biology and pathobiology. Science. 2003 Dec 5;302(5651):1772-5.

b.     Miller-Fleming L, Antas P, Pais TF, Smalley JL, Giorgini F, Outeiro TF. Yeast DJ-1 superfamily members are required for diauxic-shift reprogramming and cell survival in stationary phase. Proc Natl Acad Sci U S A. 2014 May 13;111(19):7012-7.

2. Sirtuins and the intersection between aging and neurodegeneration. During my postdoctoral work, I found that pharmacological or genetic inhibition of sirtuin 2, a member of the aging-associated family of sirtuin proteins, was protective in cell and animal of Parkinson’s disease. This was a landmark study published in Science. In my own lab, we have extended those studies and discovered sirtuin 2 can regulate microglial activation and brain inflammation, and we are heavily investigating the molecular mechanisms mediating the effects observed in models of Parkinson’s disease. Representative publications include:

3. Defining the mechanisms of toxicity associated with protein aggregation. A major interest in the field is the definition of the mechanisms of proteotoxicity. My work in yeast and mammalian cell and animal models laid the foundation for studies where we developed novel assays to visualize and measure the effects of protein aggregation in living cells and organisms. Several highly cited articles include:

a.     Outeiro TF, Putcha P, Tetzlaff JE, Spoelgen R, Koker M, Carvalho F, Hyman BT, McLean PJ. Formation of toxic oligomeric alpha-synuclein species in living cells. PLoS One. 2008 Apr 2;3(4):e1867.

4. Defining the contribution of epigenetic regulation in neurodegeneration. The interplay between the environment and genetics is thought to explain the vast majority of cases of Parkinson’s and other neurodegenerative disorders. In addition, the complexity of these disorders suggests additional mechanisms need also be considered. Among these, epigenetic regulation of gene expression, and transcriptional deregulation, appear as major possibilities. I was the senior researcher on several studies already published, and we are further pursuing these lines of research. As examples, I highlight the following articles:

a.     Marques SC, Lemos R, Ferreiro E, Martins M, de Mendonça A, Santana I, Pereira CM*, Outeiro TF*. Epigenetic regulation of BACE1 in Alzheimer's disease patients and in transgenic mice. Neuroscience. 2012 Sep 18;220:256-66. *Co-corresponding authors.
