Our research investigates the role of macrophages in human health and disease. Macrophages are the most abundant immune cells resident at interfaces with the microbiota. We investigate the development, activation and microenvironmental programming of macrophages and the impact on tissue homeostasis, mucosal control of bacteria and pathogenesis of streptococcal, staphylococcal and mycobacterial infections.

Main methods:

  • Clinical studies
  • Infection models in vitro and in mice (including fate mapping)
  • High resolution and time lapse microscopy
  • Flow cytometry of rare tissue cell subsets

RESEARCH THEMES

Major topics of the laboratory are:

  • Macrophage differentiation in tissue immunity against mycobacteria. Multinuclear macrophages (MGC) are the hallmark of mycobacterial granulomas. We investigate the cellular and metabolic basis of MGC formation in granulomas as potential diagnostic and therapeutic targets in mycobacterial infections. A specific focus lies on lipid biosynthesis and macrophage progenitors.
  • Development and environmental adaptation of sub-mucocutaneous and CNS macrophages at the beginning of life. Key questions: Are microanatomical niches imprinting differentiation programs on macrophages ? How does origin and self renewal impact on these processes? How does niche driven macrophage adaptation impact on tissue defense against staphylococci and streptococci and on tissue repair?
  • Impact of early cytomegalovirus infections on macrophage/ monocyte programming. Key questions: What is the influence of cytomegalovirus infections on intestinal macrophage development? How does early cytomegalovirus infection affect the immune response to bacterial infections later in life?
  • Role of macrophages in intestinal homeostasis. Key questions: Which signaling events guide regulatory properties of lamina propria macrophages? Can synthetic macrophages be engineered as cell therapy for intestinal inflammation?
  • Monogenetic defects in cellular innate immunity. Key questions: Which genes in myeloid and epithelial cells are essential for anti-microbial defense in children? How do aberrations in these genes drive immunopathology?
