Susan Joyce

Biography

Dr Susan Joyce graduated with a B.Sc (joint hons) from NUI Maynooth in Biology and Mathematics and a research PhD in host-microbe interactions. She was awarded a Marie Curie Fellowship to examine cis and trans acting factors affecting mRNA synthesis and microbial gene expression at the Ecole Normal Superieure, Paris which included a stint at the Max Planck Institute, Berlin. Before returning to UCC, Dr Joyce was a postdoctoral scientist at Trinity College Dublin and the Univerity of Bath, UK. Dr Joyces’ main interest is in microbial genetic and biochemical systems that alter eukaryotic host reponse. Susan is currently a Lecturer in the School of Biochemistry and Cell Biology and a funded Investigator in the APC Microbiome Ireland as part of the Spoke 4 Host- Microbe Dialogue.

Research Interests

    I am interested in the genetic and biochemical basis of host-microbe interactions, their regulation and outcomes. RESEARCH GROUP OVERVIEW: Gut microbial changes are shaped by many factors, including genetics, diet and environmental factors.  They are recognised as influential in gut development and homeostasis, immune function and local and systemic signalling. There is redundancy for function within the gut microbiome so that “altered function or loss of function” can lead to changes in host signalling favouring different health outcomes.  The lab is interested in microbial functions that can impact health and longevity.  The group has focused on microbial host-metabolite modification systems (for bile acids and more recently fatty acids) and the resulting impact on host signalling processes to influence host processes in health and in disease status. A layered research approach has identified key roles for microbial bile acid metabolism function, strains have been isolated to alter or diversify the bile acid pool and in doing so, local and systemic cell signalling.  Knock on effects include circadian rhythm changes, altered metabolism, immunity, hormonal and developmental adjustments.  A simplified approach (cloning, overexpression, mutational analysis) has assigned specificity of function to different classes and types of bile metabolizing microbial enzymes so as to match microbial activity to disease state deficits.  The use of cell lines and models has revealed impact. We have examined these collective microbial-metabolite-signalling changes over time, in the context of obesity, NAFLD, CVD, CRC in model systems and for their translation and relevance for humans -in the case of CRC and IBDs.  In the lab, we examine gut-specific and systemic impacting microbial functions through a range of different means including molecular genetics, protein expression analysis, targeted and untargeted metabolic analysis of cell, microbial and host material and on the microbiota themselves.
