Centrum für Chronische Immundefizienz - CCI

Research Areas

  1. Immunological control of streptococci and staphylococci as harmless colonizers at mucocutaneous sites (skin, intestine). Impact of individual development on this control. This work involves animal models, where progression from bacterial colonization to invasion can be studied and manipulated, analysis of bacterial isolates from patients, etc.
  2. Cell autonomous interaction and signaling events between macrophages, monocytes and granulocytes and bacteria. Areas of interest are receptor-effector interactions, cellular programming and handling of bacteria. Reporter assays, confocal microscopy and live cell imaging are critical tools.
  3. Development and differentiation of macrophage subsets in vivo. We are particularly interested in postnatal development of macrophage that reside close to colonizing bacteria. We use reporter mice, conditional mice and stem-cell derived macrophages.
