Abstract: Small vessel disease (SVD) is a group of conditions that affect micro-vessels of the cardiovascular system. Cerebral SVD accounts for a quarter of all strokes and is a major cause of cognitive impairment in elderly, becoming the second leading cause of dementia after Alzheimer’s disease. Due to incomplete understanding of the molecular mechanisms of the disease, there have not been specific treatments. Using genetic form of SVD as human disease models in combination with induced pluripotent stem cell (iPSC) and CRISPR gene editing technologies, we aim to understand how the vascular pathology leads to neural dysfunction. We have established a number of genetic iPSC SVD disease models and started to understand the functional interactions of neurovascular cell types and how these were impaired by disease-causing mutations in areas such as angiogenesis, cell growth and survival, and the blood-brain barrier function. By interrogating the patient-specific iPSC disease models, our ultimate aim is to identify disease biomarkers and drug targets. Beyond SVD, we have applied iPSCs in other medical research areas including vascular tissue engineering and lung organoids.

02:20-02:45pm Cryo-EM Structures of Tau Filaments in Human Neurodegenerative Diseases

Abstract: The ordered assembly of microtubule-associated protein tau into abnormal amyloid filamentous inclusions underlies many human neurodegenerative diseases, called tauopathies. Tau inclusions display distinct cellular and neuroanatomical distributions in different tauopathies. Six tau isoforms are expressed in the normal adult human brain-three isoforms with four microtubule-binding repeats each (4R tau) and three isoforms that lack the second repeat (3R tau). In various diseases, tau filaments can be composed of either 3R or 4R tau, or of both. Morphological and biochemical differences suggest that tau filaments adopt disease-specific molecular conformations, which may give rise to different neuropathological phenotypes, like prion strains. Using cryo- electron microscopy, we recently reported the structures of tau filaments from patients with Alzheimer’s disease and chronic traumatic encephalopathy, which contain both 3R and 4R tau, as well as from patients with Pick’s disease, which contain 3R tau only. Here we determine the structures of tau filaments from patients with corticobasal degeneration, progressive supranuclear palsy, globular glial tauopathy, argyrophilic grain disease, inherited cases of mutations at positions +3 or +16 in intron 10 of MAPT (the microtubule-associated protein tau gene), which contain 4R tau only. These findings show how tau can adopt distinct folds in the human brain in different diseases and suggest a hierarchical classification of tauopathies on the basis of their filament folds, which complements clinical diagnosis and neuropathology and also allows the identification of new entities. We also found heparin induced in vitro aggregation yields different structures from those observed in brain. Tau isoform composition, post-translational modifications or interactions with cofactors may determine which structures are formed in brain.

02:45-03:10pm Stimuli-Responsive Polymer 3D-Scaffolds Guide Cell Fate for Soft Tissue Regeneration
Professor Wenhui Song, The UCL Centre for Biomaterials in Surgical Reconstruction and Regeneration, Division of Surgery and Interventional Science, University College London (UCL), UK

Abstract: The cellular microenvironment is dynamic, remodeling tissues lifelong. The biomechanical properties and morphology of the extracellular matrix (ECM) influence the function and differentiation of cells and stem cells. While conventional artificial matrices or scaffolds for tissue engineering are primarily static and passive models presenting well-defined stiffness, they lack the responsive changes required in dynamic physiological settings. Engineering synthetic scaffolds with varying elastic moduli is possible, but often lead to stiffening and chemical crosslinking of molecular structure with limited control over scaffold architecture. The presentation will give an overview about recent development of thermal-responsive elastomer scaffolds with tuneable stiffness and hierarchical structure. The different cellular responses and differentiation during the stiffness relaxation of 3D printed scaffolds in vitro and in vivo have been systematically studied. The stiffness relaxation is found to regulate proliferation and differentiation of human bone-marrow derived mesenchymal stem cells (hBM-MSCs) towards the chondrogenic and osteogenic lineages. The optimised epithelium of human bronchial epithelial cells co-culture with hBM-MSCs on the functionalised scaffolds demonstrate layered respiratory-like tissue. The results offer a reproducible patient-specific approach to generate physiologically relevant 3D biomimetic systems and advance our understanding of soft tissue regeneration for drug discovery, organ regeneration and surgical reconstruction.

03:10-03:35pm Ways to Die and Life After Death: How Cells Do Their Tricks
Dr Yun Fan, Structural and Molecular Cell Biology, School of Biosciences, University of Birmingham, UK
show more/less

 

Abstract: Balanced cell death and cell proliferation is critical for the maintenance of tissue homeostasis in multicellular organisms. Intriguingly, apoptosis and necrosis, two major forms of stress-induced cell death, are frequently interlinked and tightly controlled. How do cells choose one way or the other to die? How do dying cells communicate with their neighbours to stimulate tissue recovery? What are the implications of these cellular phenomena in human diseases including cancer? This talk will introduce our research on these topics using Drosophila as a model organism.

03:35-04:00pm Neuroimaging Biomarkers of Neurodegenerative Dementia Across Lifespan
Professor Li Su, Institute for Translational Neuroscience, University of Sheffield, UK

Abstract: (Background) Dementia currently affects over 850,000 people in the UK, costs the UK £26 billion a year, and is estimated to increase to over 1 million people by 2025 with increasing life expectancy (Alzheimer’s Society 2015 reports). Pivotal to responding to this “time bomb” are biomarkers that predict susceptibility to dementia. Neural degeneration and dysfunction leading to dementia may begin decades before symptoms and cognitive decline present. Hence, the recognition of early imaging markers of dementia across different stages of lifespan may allow more effective intervention or even prevent dementia from happening.

(Methods and Results) Here, I will present current and recent neuroimaging research conducted in my lab and collaborating centres nationally (Cambridge, Oxford, Imperial and Edinburgh) and internationally (Dublin and China) in seeking for potential early neuroimaging biomarkers for neurodegenerative dementia. I combine multimodal imaging with genetics as well as machine learning methods to reveal neural mechanisms underlying dementia, and how risk factors (e.g. family history of dementia, APOE and MAPT genotype) affect brain structure, functions and behaviours across lifespan including in young and mid aged individuals as well as established patients with dementia.

(Conclusions) Multimodal imaging and genetics have the potential to identify early changes in brain structure and functions decades before clinical symptoms occur.

02:40-03:00pm Replication Stress-Induced Mitotic Bypass and Whole Genome Duplication
Mr Jingkun Zeng, Boehringer Ingelheim Fonds PhD fellow, Francis Crick Institute, UK
show more/less

 

Abstract: Whole genome duplication (WGD) is a frequent event in cancer evolution and an important driver of aneuploidy. The role of the p53 tumour suppressor in WGD has been enigmatic: p53 blocks proliferation of tetraploid cells, acting as a barrier to WGD, but can also promote mitotic bypass, a key step in WGD via endoreduplication. In wild type p53 tumours, WGD is frequently associated with activation of the E2F pathway, especially amplification of CCNE1, encoding cyclin E1. Here we show that elevated cyclin E1 expression causes replicative stress, which activates Chk1-dependent G2 phase arrest. After prolonged arrest, p53, via its downstream target p21, then promotes mitotic bypass. Cyclin E expression suppresses p53-dependent senescence after mitotic bypass, allowing cells to complete endoreduplication. We further show that other oncogenes including HRasV12, can induce endoreduplication via replicative stress. Our results support a positive role for p53 in cancer evolution through WGD.

03:30-04:00pm Lipid-Immune Interactions and Barrier Inflammation
Dr Chengcan Yao, Reader / MRC Career Development Award Fellow, Centre for Inflammation Research, University of Edinburgh, UK
show more/less

 

Abstract: Inflammation at the barrier line is triggered by exogenous stimuli such as infections, toxins and mechanical injury. Proper inflammatory responses are required for the host defence against external invasions and help improve tissue repair post damage. However, unchecked and continuous inflammatory responses promote chronic inflammation and barrier dysfunction. Immune cells play a key role in barrier homeostasis and their overreactions drive barrier inflammation and disease. Eicosanoids are a group of bioactive lipids that are present at biologically active levels under the steady state, and their levels are considerably elevated in response to external stimuli, for example, upregulation of cyclooxygenases and prostaglandin E2 (PGE2). As one of the well-known mediators of inflammation, PGE2 can exert its actions on various cell types as its receptors are widely expressed. We have recently examined the effects of PGE2 on immune cells especially lymphocytes and the PGE2-immune interplay determines local and systemic inflammatory responses. In this presentation, I will show our recent findings of interactions between PGE2 and numerous immune cell types and how these interactions influence health and inflammatory diseases at different barrier tissues such as the skin, lung and intestine.
