Research Assistant in Cellular Trafficking (MHLCM1200)

Are you an early career researcher looking for your first challenge? Do you have laboratory experience in cell biology/cellular trafficking/Super-Resolution microscopy? Do you want to further your career in one of the UK’s leading research intensive Universities? 

A two year position is available for a highly motivated research assistant to work with Dr Lynn McKeown on her MRC funded research grant to address a fundamental gap in our understanding of the role of perturbed cellular degranulation in inflammation. 

The specific objective of this research position is to determine the mechanisms underlying mast cell degranulation in response to various stimuli, with specific emphasis on the role of Rab GTPases. First, we will use Super-Resolution microscopy in order to establish a role for Rab46 in granular trafficking. The research assistant will investigate Rab46 localisation and granular kinetics in response to human mast cell stimuli (IgE, TLR ligands, ATP, C3a and appropriate controls). Rapid kinetics will be observed in live cells overexpressing GFP-Rab46 using iSIM. In addition, overexpression of any exonic Rab46 variants (identified in corresponding patient genetic studies) will be used to analyse the effect of the mutation on granular trafficking. The research assistant will also perform quantitative immunoassays and other biochemical analyses on mast cells extracted from mouse Rab46 -/- mast cells to determine the effect of Rab46 on the selective release of granule contents. Collectively the results from this work will lead to 1) enhanced understanding of what drives mast cell degranulation, 2) novel targets to intervene to prevent perturbed degranulation and 3) further understanding of the role of mast cells in inflammatory diseases.
