    Alexander Buntru
    Lehrstuhl für Zellbiologie, Universitat Konstanz, Konstanz, Germany
    BMC Biol 7:81. 2009
    ..Here, we provide a methodological approach to exploit fluorescence resonance energy transfer (FRET) to visualize pathogen-initiated signaling events in human cells...
  2. pmc Grb14 is a negative regulator of CEACAM3-mediated phagocytosis of pathogenic bacteria
    Kathrin Kopp
    Lehrstuhl Zellbiologie, Universitat Konstanz, 78457 Konstanz, Germany
    J Biol Chem 287:39158-70. 2012
    ..Therefore, Grb14 is the first negative regulator of CEACAM3-initiated bacterial phagocytosis and might help to focus granulocyte responses to the subcellular sites of pathogen-host cell contact...
