Summary
T lymphocytes play a central role in the adaptive immune response, which specifically targets pathogens and cancer cells and creates the immunological memory. Activation of sometimes as little as one single receptor on a T cell triggers a cellular signal that rapidly expands and branches out in a multitude of sub-signals. Here we will use a combination of novel microscopy approaches to visualise how a network of dedicated intracellular compartments is in charge of these processes.
Macrophages are important cells at the front-line of immunity where one of their main roles is to release anti-bacterial proteins. We will study the macrophage molecules, subcellular organelles and pathways that help to release these proteins to kill bacteria and fight infection. Our studies will identify new cellular targets for boosting immunity and treating inherited diseases with defective macrophage function.
