Van Ginderachter Team - Myeloid Cell Immunology Lab (MCI)

Research field: Myeloid cells in inflammation and cancer

Group leader: Prof. Dr. Ir. Jo Van Ginderachter


Research topic

Our mission is to use the heterogeneity of myeloid cells (MCs) as an in vivo sensor to track inflammatory responses and as a target for therapeutic intervention. Based on markers that allow discrimination between selected MC subpopulations, we fully invest in the development of innovative tools to visualize and modulate the in vivo differentiation, recruitment and function of selected MC subpopulations in inflamed tissues. These include in particular the identification of markers for different tumor-associated macrophage or dendritic cell populations, as well as Kupffer cell- and microglia-specific markers, to generate transgenic (knock-in) mice allowing the tracking and ablation of selected MC populations. Such tools will reveal the role of these MCs in homeostasis and in distinct models of tumor growth and liver or brain injury. We also aim to develop original strategies to overcome inflammation-associated immunopathology of infectious and non-infectious diseases. In this regard, we fully exploit the strategic advantage of nanobodies, i.e. camelid-derived single-domain antibody fragments and their engineering platform as tools for in vivo MC-targeted delivery of imaging agents (radionuclides, gold- or magnetic nanoparticles) and drugs that can remediate the inflammatory disease outcome and be translated readily into the clinic.

Area of expertise

  • Tumor immunology, with a particular focus on the role of myeloid cells (mainly macrophages and dendritic cells) in the tumor microenvironment.
  • Liver immunology, with a particular focus on the role of tissue-resident Kupffer cells versus bone marrow-derived myeloid cells during parasitic infections (mainly Trypanosoma), bacterial infections (mainly Listeria) and sterile liver inflammation (including liver cancer). Knock-in mice to specifically study the role of Kupffer cells were generated.
  • Brain immunology, with a particular focus on the role of tissue-resident microglia versus bone marrow-derived myeloid cells during infectious inflammation (Trypanosoma, Listeria), glioma and neuronal wiring.
  • The use of Nanobodies and their engineering platform for the imaging and therapeutic targeting of myeloid cells in vivo.
