Hornung Lab - Innate Immunity

Research Topics

  • Innate Immunity
  • Inflammasome
  • Cytoplasmic Nucleic Acid Sensing
  • Genome Engineering

We are trying to understand what mechanisms are employed by the innate immune system to distinguish self from non-self or harmless from dangerous, respectively. Central to this complex task is a repertoire of pattern recognition receptors (PRRs) that have evolved to detect the presence of microorganisms. The ligands or targets of these PRRs are commonly referred to as microbe-associated molecular patterns (MAMPs). Read more...
