Dr. Frederick Sheedy
Associate Professor, Biochemistry
Biography
I recently established my independent research group within the School of Biochemistry & Immunology at Trinity College, Dublin (TCD), Ireland, examining macrophage function in health and disease. I pioneered miRNA research in the field of innate immunity during my graduate studies in the O'Neill Lab, resulting in a Nature Immunology first author publication and this emerging field was highlighted by a Nature Reviews Immunology article, which I co-wrote. I obtained a postdoctoral fellowship from the American Heart Association to study the molecular mechanisms of inflammation in disease at NYU. This transformative work was published in Nature Immunology and alongside my recent work on tuberculosis, funded by a Starting Investigator grant from Science Foundation Ireland, fueled my interest in macrophage-driven disease. My recent work published in Cell Reports, J Immunology and AJRCMB (as last author), has uncovered the regulation of anti-microbial function by metabolism and through multiple industrial partnerships with local food companies , I have begun to examine the potential for β-glucan training of immunity. I aim to use this to consolidate my research in the emerging area of innate immune training and how this can improve resistance to infection.

- Measuring monocyte function as a marker of cardiovascular disease and immune activation
- Summary
- Atherosclerosis, a leading cause of cardiovascular disease, is triggered by recruitment of macrophages to areas of lipid deposition along vessel walls. The macrophages are recruited as precursor monocytes and differentiate locally to proinflammatory macrophages. Evidence suggests the type of monocyte recruited is affected by numerous factors. This project proposes to develop technologies to profile monocyte precursors in circulation by examining key mRNA and protein expression as biomarkers. This can be applied to approaches to monitor monocytes in disease susceptible patients.
