Chris Tibbitt team - Defining the metabolic signatures of tissue resident human ILCs
The current focus of the Chris Tibbitt team is understanding tissue ILC specific metabolism in the context of allergy and cancer.
The Chris Tibbitt team is part of the Jenny Mjösberg research group at the Center for Infectious Medicine (CIM).
About our research
Induction of any immune response requires metabolic changes. While a number of genes and pathways have been evaluated in T cells, the factors that link activation to alterations in metabolic state remains to be profiled in depth for human ILCs. Using the latest techniques in metabolic profiling and single cell mutli-omics, we aim to map the metabolic profiles of human ILCs across a range of tissues and inflammatory conditions. Our aim is to assess whether biological therapies can impact upon cell intrinsic metabolism. We are also seeking to determine how host metabolic state (e.g. obesity) can alter the ILC phenotypes during asthma.
Chris completed his PhD studies at Newcastle University in 2015 characterizing the influence of TCR signaling on the development of autoimmune Th17 cells. During his postdoctoral studies in the Coquet and Mjösberg labs, he worked to define T helper cells and ILC responses using single cell based approaches.
Sabrina Ferreira completed her PhD at University of São Paulo in 2019 where she worked on the modulating effect of insulin in asthma. In 2017-2018 she worked as a visiting PhD student at Karolinska Institutet studying the effect of insulin secretion in beta cells in diabetes mellitus. From 2019-2022, she is a postdoctoral fellow at Karolinska Institutet, focusing on dissecting the underlying mechanism that regulates the tumor-associated macrophage's (TAMs) immunosuppressive phenotype.
