Understanding the interaction between microbiota and T cell immunity

Project Details

Development of autoimmune diseases has been linked to disturbances in the microbiota that normally colonises our body surfaces. However, precisely how these microorganisms and the resulting stimulation of the immune system impact on different T cell subsets is less well understood. Building on extensive preliminary data available in the lab, this project investigates how microbiota influences T cell-mediated responses, especially in regards to their metabolism, and its influence on autoimmune disease, such as type I diabetes.
