Cluster of Excellence ImmunoSensation³

A new phase of excellence

The immune system evolves. And so do we. 

ImmunoSensation3 begins its new funding phase, building on past discoveries to explore immune diversity across scales. As a dynamic system, the immune system’s structures, functions and dynamics depend on genetic and environmental influences, lifestyle, gender, previous illnesses and age. These influences are reflected at the molecular, the cellular and the systemic level of the body. The resulting constant change and natural diversity of the immune system is referred to as immune diversity. 

Immune diversity forms the basis for the adaptive performance of the immune system and enables an individual immune response to pathogens or tissue damage, as occurs in connection with Alzheimer's, cancer, heart attacks or rheumatism. The aim of ImmunoSensation3 is to better understand the variability of the immune system in order to enable individualized and precise approaches for diagnostics, prevention and therapy.

ImmunoSensation3 is a Cluster of Excellence at the University of Bonn funded by the German Research Foundation (DFG). We address the immune system as a sensory organ for health, which we term the immune sensory system. We are immunologists, neurobiologists, systems biologists, biochemists, biophysicists and mathematicians from the Faculty of Medicine and the Faculty of Mathematics and Natural Sciences at the University of Bonn, the University Hospital Bonn (UKB) and the German Centre for Neurodegenerative Diseases (DZNE) of the Helmholtz Association.

Founded in 2012, ImmunoSensation is currently in its fifteenth year of funding. We will continue to pursue our mission of innovative science in immunology. Further, we link immunology to other systems, such as the metabolic system and the nervous system. Ultimately, we want to better understand the intimate connection between the immune sensory system and human health and disease.

What Makes Sea Urchin and Salmon Sperm Swim

A recent study by the Max Planck Institute for Multidisciplinary Sciences and the University of Bonn shows that pH plays a crucial role in sperm motility in sea urchins and salmon. A rise in pH activates the enzyme soluble adenylyl cyclase (sAC), which produces the messenger molecule cAMP and thereby regulates sperm movement. This mechanism may be widespread in many marine invertebrates and fish. The findings have now been published in the Journal Proceedings of the National Academy of Sciences.

Immune cells remember their location

A new AI-based method reconstructs spatial information about where immune cells were originally located in an organ, even after these cells have been removed from the tissue and analyzed individually. To accomplish this, Researchers at the University Hospital Bonn (UKB) and the University of Bonn use the transcriptome, i.e., the entirety of all messenger RNA transcripts produced by genes within a cell at a given time. The work has now been published in the journal Advanced Science and introduces the new MERLIN algorithm.

B cells maintain antigen presentation in the splenic marginal zone

A team of international researchers, including ImmunoSensation³ members Prof. Niels Lemmermann and Prof. Andreas Schlitzer, shows that B cells support antiviral CD8⁺ T-cell responses beyond antibody production. In a murine CMV model, B-cell deficiency weakened virus-specific CD8⁺ T-cell responses. Mechanistically, B-cell-derived lymphotoxin β maintained CD169⁺ macrophages and Langerin⁺ cDC1 cells in the splenic marginal zone, enabling efficient T-cell priming. The study was published in Cellular & Molecular Immunology.
