Human T-cell immunology—from the mechanistic basis to translational applications
We are a research group interested in the fundamental mechanisms that shape human T cell memory responses in health and disease. Our long-term goal is to develop novel therapeutic strategies in settings of autoimmunity, cancer and chronic infections.
The primary focus of our laboratory is to investigate the regulation of human T cells in health and disease. We address fundamental questions about the mechanistic basis of human T cell memory formation, stabilisation, and modulation. We also investigate T cell communication with the local tissue microenvironment in settings of health and disease. Our research has unravelled novel T cell specialisations, including GM-CSF and IL-1alpha production (Noster et al.,Sci Transl Med 2014; Chao et al.,Nat Immunol 2023), and anti-inflammatory Th17 cells (Zielinski et al.,Nature 2012), with significant implications for chronic infections and the pathogenesis of autoimmune diseases such as multiple sclerosis.
We are particularly interested in the mechanisms by which tissue-resident immunological memory is generated and maintained in human tissue (ERC Grant). The reciprocal interactions of T cells with the tissue microenvironment, including the microbiota, metabolites, and even ions, are of particular interest (Soll et al.,Nat Immunol 2024). They shape the functionality of the tissue-resident memory T cell compartment, “imprint” tissue-tropic migration and residence, and represent interesting targets for novel immunomodulatory therapies in settings of autoimmunity, cancer, and chronic infections (de Almeida et al.,Sci Immunology 2022).
To address our goals, we use a translational approach, combining the analysis of healthy and pathological tissue samples with novel cutting-edge technologies, gene editing and high-dimensional data analysis. We are studying patients undergoing extensive in vivo perturbation of their immune system, i.e. by systemic therapies with immunomodulatory drugs (biologics) or by stem cell transplantation. We also take advantage of studying patients with genetic immunodeficiency syndromes.
Together, our research aims to provide a fundamental basis for human T cell regulation and to support translational applications for the design of therapeutic targets and adoptive T cell therapies in settings of autoimmunity, infections, and cancer.
