About the Presenters
Paula Niewold, PhD
Department of Infectious Diseases
Leiden University Medical Centre
Dr. Paula Niewold is an immunologist currently working as a postdoctoral researcher at the Department of Infectious Diseases at the Leiden University Medical Centre. She is interested in host-pathogen interactions and how they impact the outcome of disease. She has studied these interactions in models of cerebral malaria, West Nile virus encephalitis, psoriasis, and tuberculosis using high-dimensional flow, mass, and imaging mass cytometry. She is an ISAC Marylou Ingram Scholar.
Thomas Ashhurst, PhD
Immunologist and High-Dimensional Cytometry Specialist
Sydney Cytometry Facility
University of Sydney
Dr. Thomas Ashhurst is an immunologist and high-dimensional cytometry specialist with the Sydney Cytometry Facility at the University of Sydney. He develops and applies a range of single-cell cytometry technologies and computational analysis tools to map dynamic immune responses over time, space, and disease. In particular, he applies these approaches to the study of immunology and infectious disease, including emerging pathogens such as COVID-19, Zika virus encephalitis, and West Nile virus encephalitis. He is an ISAC Marylou Ingram Scholar.
In conventional fluorescence cytometry, each fluorophore in a panel is measured in a target detector, through the use of wide band-pass optical filters. In contrast, spectral cytometry uses a large number of detectors with narrow band-pass filters to measure a fluorophore's signal across the spectrum, creating a more detailed fluorescent signature for each fluorophore. The spectral approach shows promise in adding flexibility to panel design and improving the measurement of fluorescent signal. However, few comparisons between conventional and spectral systems have been reported to date. Here we present our findings comparing conventional and spectral approaches to cytometry—including comparisons of compensation and unmixing—and evaluate the use of spectral cytometry for immune profiling in viral diseases.
- Gain an understanding of the essential differences between conventional and spectral approaches to cytometry.
- Appreciate the differences between compensation and spectral unmixing.
- Consider applications for spectral cytometry in the context of immunological studies.
