Research in Sarah’s laboratory focuses on the metabolism and interlinked immune function of immune cells in health and disease.
Metabolism describes how cells take up nutrients and break them down to provide energy and building blocks. This changes dramatically in immune cells when they become engaged in an immune response and is critical for their protective activity. Sarah’s lab aim to understand how this happens, and how it becomes dysregulated in diseases associated with altered immune cell function, including autoimmunity and cancer.
We are particularly interested in how the bone marrow environment impacts immune cell metabolism and protective activity in the blood cancer, multiple myeloma. We also study fundamental metabolic processes in immune cells, for example synthesis of the redox cofactor, NAD.
A recent research project investigated how an inflammatory cytokine (messenger molecule) promotes metabolic activity of T lymphocytes in rheumatoid arthritis. The article describing the results of this research can be accessed without access charges here:
