Microbial Immune Regulation

The microbiota encompasses a diverse population of microorganisms that colonize many body sites such as skin and intestine of multicellular hosts. The composition of the microbiota in humans is highly variable and is influenced by nutrition, immune competence, illness and use of medication (especially antibiotics). We are interested to enhance our understanding on how these microbial communities affect human infectious diseases and how they can be manipulated to treat diseases.

  • 46_Mit Mäusekötteln gegen Morbus Crohn – neue Wege gegen chronisch-entzündliche DarmerkrankungenEntzündliche Darmerkrankungen bedeuten großes Leid für die Patienten, sind kaum behandelbar und bisher wissen weder Ärzte noch Forscher, wie es dazu kommt, dass allein in Deutschland etwa 300.000 Menschen an Krankheiten wie Morbus Crohn und Colitis Ulcerosa leiden. Wissenschaftler am HZI suchen in den Bakteriengemeinschaften, die im Darm leben nach Antworten. Begleiten Sie Till Strowig ins Labor und hören Sie zu, wie er ein Probenröhrchen voll Mäuseköttel für die Forschung homogenisiert…
