Cellular communication and diabetes

Deirdre Kavanagh (PDRA)
Institute of Biological Chemistry, Bioengineering and Biophysics, Heriot-Watt University
Funded by MRC and Wellcome Trust
Using single molecule localisation microscopy such as PALM and STORM this project aims to understand the plasma membrane organisation of tSNARE proteins underlying insulin secretion in β-cells under normal physiological conditions and how this is altered in Type 2 related hyperglycemia. Previous work combined these techniques with Fluorescence Cros Correlation Spectroscopy to study SNARE protein interactions in neuronal cells.
3D Printing of Tumours
Dr Nick Leslie (PI)
Miguel Hermida (PhD)
Institute of Biological Chemistry, Bioengineering and Biophysics, Heriot-Watt University
Funded by Anonymous Trust
This project involves the development of a 3D printing strategy, which uses common biocompatible hydrogels to create multilineage tumour-like structures. These are visualised in ESRIC using live-cell 3D confocal imaging with the aim to study the tumour microenvironment and provide novel highly-reproducible models for preclinical drug testing.

Distribution of pathogen associated molecular patterns on the Candida albicans cell surface
Prof. A. Brown (PI)
Dr Judith Bain (PDRA)
School of Medicine, Medical Sciences and Nutrition, University of Aberdeen
Funded by MRC
This project investigates the cell surface arrangement of pathogen associated molecular patterns (PAMPS), including β-glucan, on the wall of the fungal pathogen, Candida albicans. In this collaboration, Structured Illumination Microscopy (SIM) is used to visualise alterations in PAMP exposure in response to altered host factors.

Analysis of human lung tissue and bacterial labelling compounds
Dr Kev Dhaliwal (PI)
Dr Tushar Choudhary (PDRA)
Centre for Inflammation Research, University of Edinburgh
Funded by EPSRC
This collaborative project between Heriot-Watt University and Edinburgh University investigates the properties of markers for lung diseases, which forms part of the Proteus project; developing a tool for next-generation diagnostic testing of lung disease. Fluorescence Lifetime Imaging Microscopy (FLIM) is used to study the fluorescent properties of these markers.

Investigating granular dynamics in renin-producing primary cells
Dr John Mullins (PI)
Dr Charlotte Buckley (PDRA)
BHF Centre for Cardiovascular Science, University of Edinburgh
Funded by British Heart Foundation
The transport and dynamics of renin-producing granules inside primary juxtaglomerular cells has been investigated in a collaborative project between Universities. This research has been possible using TIRF microscopy and photoactivation techniques at ESRIC allowing live-cell tracking and quantification of calcium dynamics.

Super-Resolution imaging of postsynaptic proteins in the brain

Dr Matthew Broadhead (PDRA),
Centre for Neurodegeneration, University of Edinburgh and School of Psychology and Neuroscience, University of St. Andrews
Funded by Principals Career Development Scholarship
Gated stimulated emission depletion (g-STED) microscopy was used in this project to quantify PSD95eGFP organisation at the nanoscale in brain tissue to understand the underlying molecular framework of cognitive functions at the level of the synapse. This work was published in Nature Scientific Reports in May 2016 as part of a Wellcome Trust funded project at the University of Edinburgh. Matthew now works as a PDRA in St Andrews and continnues to collaborate with ESRIC.

Left panel, PSD95-eGFP (green) imaged with a confocal (Con) microscope and the Alexa Fluor 594-filled spine is shown in magenta. Right panel, g-STED image of PSD95-eGFP in same spine. Scale bars 500 nm.
Protein-Protein interactions in the NMD pathway
Professor Javier Caceres (PI)
Dr Dasa Longmann (PDRA)
Human Genetics Unit, University of Edinburgh
Funded by MRC
NMD (Nonsense-mediated mRNA Decay) is an mRNA quality control pathway that ensures rapid degradation of mRNAs that carry premature termination codons, and also modulates expression of a large number of physiological transcripts. The progression of this pathway is governed by dynamic assembly of NMD complexes that leads to degradation of targeted transcript. This project uses FRET-FLIM to investigate direct protein-protein interactions between the core NMD factor UPF1 and other factors that play role in this pathway.
Investigating epithelial cell mechanics
This project aims to investigate the mechanical properties of particular cell types at a multi-cellular, rather than single cell level, to further understand how interactions at a cellular level can be translated into whole organ structure. Cellular mechanics are investigated using Atomic Force Microscopy.
