PhD Student - Function And Regulation Of Type 6 Secretion System

Über den Job

The

Biozentrum of the University of Basel

is one of the world's leading life sciences institutes. With 33 research groups and 500 employees, we are a dynamic and international research community that has spawned many fundamental discoveries in biology and medicine as well as several Nobel laureates. Join our community!

The research group of Prof. Marek Basler seeks to appoint a highly motivated PhD student in molecular microbiology, protein biochemistry and bacterial cell biology. The project focuses on unraveling the molecular mechanisms that control the assembly and function of the Type 6 secretion system.

The project

The bacterial Type 6 secretion system (T6SS) is one of the largest dynamic assemblies in Gram-negative bacteria. It shares evolutionary origins with contractile phage tails and other extracellular contractile protein translocation nanomachines. Importantly, the unique mode of action of T6SS allows bacteria to deliver folded proteins across membranes of neighboring bacterial or eukaryotic cells (

). Subcellular localization of T6SS assembly and timing of its firing is tightly regulated in various bacteria:

• Spatial positioning

  : Live-cell super-resolution imaging showed that Acinetobacter position their T6SS specifically at contact sites with neighboring bacteria (
  ).

• Tit-for-tat response

  : Atomic force microscopy and live-cell imaging demonstrated that T6SS assembly in Pseudomonas responds to attacks by sensing membrane damage (
  ).

• Host interaction

  : During infection, T6SS in Burkholderia assembles when bacteria are trapped in membrane protrusions, enabling cell-to-cell spread (
  ).

Despite these breakthroughs, we still lack a fundamental

mechanistic understanding

of how

precise timing and spatial localization

are achieved, and the

specific signals

that trigger T6SS assembly remain unknown.
