We aim to understand how rare and common gene variants interact functionally at a cellular and systems level to cause neurological disorders. Our disease areas of interest are migraine and neurodegeneration. My group now uses our unique cell culture and animal models to identify novel drug targets. Through collaboration with MRCT and industry to screen compound libraries against these targets, we have identified hit compounds which we will continue to develop towards clinical application. I recently successfully led a large consortium bid (25 academic partners, 11 pharma partners) to develop human induced pluripotent stem cells (hiPSC) as a platform for drug discovery. The major objectives of StemBANCC are generate a well curated large bio-repository of hiPSC from a range diseases and to derive assay platforms for phenotypic drug screens. My interest in the genetics of migraine began during my graduate studies and this work led to the first identified gene associated with a common form of migraine. This was published in Nature Medicine in September 2010 with significant worldwide media interest. We are now building on this discovery using next-generation sequencing to identify other causative interacting genes, developing in vitro and in vivo models, including using patient derived stem cell models. We have now found the first example of oligogenic inheritance in migraine with cell-autonomous and systems-level interactions between migraine causative genes. An important and difficult question in neurology, is how mutations in essential and ubiquitous proteins can lead to selective toxicity of neurons. Answering this question, would provide significant insights in many disorders. We have been examining a rare form of axonal neuropathy caused by dominant mutations in the gene, GARS encoding the ubiquitous house-keeping enzyme Glycyl-tRNA synthetase. We have found disease and neuronal specificity arise from a remarkable mechanism: disease mutations confer non-canonical functions, whereby this cytoplasmic enzyme is secreted by muscle and interacts with axonal guidance receptors on motor neurons, leading to non-cell autonomous toxicity. What are the Future Aims of Your Current Group? The future aims of our group are to comprehensively address the molecular and cellular mechanisms of migraine. This will require new genomic approaches integrated with cellular and animal model phenotyping. Specifically we will use gene network and pathway analyses from hits identified in genome wide association and exome sequencing studies to generate hypotheses for disease mechanism. We can then undertake deep phenotyping of stem cell derived neurons from patients with migraine including intrinsic neurophysiological properties, synaptic function, ionic homeostasis and kinase cascades. Through exposure to known migraine inducers and migraine therapeutics followed by molecular profiling including single cell omics, we aim to identify key molecular players to then develop new migraine therapies. We will also use cell culture systems and animal models to explore how systems level pathologies may emerge. For example, migraine candidate genes may exert effects on distinct brain regions. Through generating compound mouse models and using ex-vivo brain slice electrophysiology and in vivo electrophysiology, we can gain a better understanding of how these genes affect particular brain regions and how such regions interact to produce emergent phenotypes. We will continue to work with groups such as MRCT to translate these findings into drug screens and drug development pipelines. How do These Aims Contribute to the Understanding and/or Management of Human Disease Migraine is a disorder affecting 1 in 10 people worldwide at any one time and 1 in 3 people during their lifetime. The World Health Organization ranks it as one of the leading causes of disability. However research and healthcare provision are hugely inadequate for such an important disorder. Our work will embody the philosophy of the WIMM, developing hypotheses originating from human studies and observations to then test with innovative research methods. We have now started to move beyond the single rare variant gene model or indeed common variant hypothesis for migraine since these approaches are reaching their limits. Instead we are developing new paradigms and new techniques including cellular association studies to identify the molecular determinants of disease. This will require collaborations with key researchers at the forefront of medical research, including several within the WIMM. Lay Summary of Research Headaches are common, costly and debilitating conditions. Their impact on the individual and to society is often hugely underestimated. Migraine, an important type of headache, affects one in three people over a lifetime and the World Health Organisation now ranks migraine as a leading cause of disability worldwide. For some patients migraine headaches can blight lives for years. Our group is aiming to find out why some people suffer with migraine. We know a major reason lies in our genes and we have found the first gene underlying typical migraine. We identified in a large family with migraine, a defect in the gene KCNK18, which encodes an ion channel called TRESK. TRESK is present in parts of the brain important for the development of migraine and our studies have shown that mutations in TRESK can make nerves more excitable. However there are many other genes that are also likely to predispose to migraine but they are challenging to uncover. We are using the latest technologies to reveal new migraine genes and trying to understand how different genes can interact with each other to increase migraine susceptibility. This includes the use of stem cell models of migraine. When we develop from an embryo into our adult forms, all the different specialized cells of our body arise from a type of cell called a stem cell. The two key properties of stem cells are their ability to renew themselves and to become any cell type in the body (a property called pluripotency). It is now possible to turn the clock back and transform an adult cell such as a skin or blood cell from a patient back into a stem cell. These induced pluripotent stem cells contain all the DNA and genes of the patient. We are using stem cells from patients with migraine, that we then turn into nerve cells. For the first time, we now have a way to directly assess how a migraine patient’s nerves differ from people who don’t get migraine and link this with the genetic make-up of the patient.
