Current research interests in Sarah Dimeloe’s lab focus on the metabolism and interlinked immune function of T lymphocytes in health and disease.
T lymphocytes are a key component of the immune system and comprise two subsets: CD4+ T cells, which co-ordinate immune responses against infections or cancers and CD8+ T cells, which can kill infected or cancerous cells of the body, as well as producing important cytokines (messenger molecules). Following an immune response, “memory” populations of both of these cell types remain in the body, surveying for reappearance of a threat, to which they are able to rapidly respond, in order to protect us.
Dr Dimeloe’s previous research has identified a key signal instructing the required changes in metabolism in order for CD4+ T cells to coordinate an immune response. Dr Dimeloe additionally worked to define the key metabolic traits of memory T cells that enable them to perform their specialised role. For example, Dr Dimeloe identified that memory CD4+ T cells have large and complex mitochondria, enabling them to survive in, and patrol oxygen-poor environments like peripheral tissues of the body. She also contributed to work identifying that memory CD8+ T cells are metabolically “primed” to rapidly respond to threats.
Dr Dimeloe’s research in Birmingham is now focused on how these “normal” metabolic functions are dysregulated in disease, and importantly, if such perturbations can be targeted to restore optimal T cell function and protection from disease. Specifically, Dr Dimeloe is investigating changes in the use of key nutrients by T cells during their development and in disease states. Additionally, she working to identify components of diseased tissues that may subvert T cell metabolism and interlinked immune function and delineate the mechanisms involved, with the aim of discovering potential therapeutic targets. One experimental approach that Sarah is using to ask these questions is to perform high-resolution metabolic tracing analyses, by working together with the Metabolic Tracer Analysis Core (MTAC) facility at the University of Birmingham.
Applicants should have a strong background in cell biology and experience of immunology is desirable. They should have a commitment to research and hold or realistically expect to obtain at least an Upper Second Class Honours Degree in a relevant subject.
