Host-Pathogen interactions

Manipulations of host cell processes by bacterial pathogens

Anat Herskovits Lab

Our lab of bacterial pathogenesis and cell host interactions is located at Tel Aviv University. We are interested in how intracellular bacterial pathogens manage to survive the mammalian niche and cause infection. We study the bacterium Listeria monocytogenes, which is a human facultative intracellular pathogen. We specifically ask how is L. monocytogenes metabolically adapted to grow within mammalian cells? How does it sense host derived metabolites and use this information to regulate virulence gene expression? We also ask, how does L. monocytogenes interact with its inhabiting prophages in the course of mammalian infection? Lysogenic phages are parasites, potential ‘molecular time bombs’, yet during mammalian infection they cooperate with their bacterial host. We study phage adaptive behaviours that support the survival of pathogens within the mammalian niche. Our lab combines various computational, biochemical and genetic approaches to decipher these mechanisms.
