OxTalks will soon move to the new Halo platform and will become 'Oxford Events.' There will be a need for an OxTalks freeze. This was previously planned for Friday 14th November – a new date will be shared as soon as it is available (full details will be available on the Staff Gateway).
In the meantime, the OxTalks site will remain active and events will continue to be published.
If staff have any questions about the Oxford Events launch, please contact halo@digital.ox.ac.uk
Intracellular pathogens inhabit specific cellular niches determined by the degree of compartment-specific immune surveillance and the pathogen’s need for host cell activities and nutrients. Most intracellular bacteria dwell in vacuoles while only few have conquered the cytosol, a perhaps counterintuitive situation considering the abundant energy sources available in the cytosol for bacterial growth. Potent cytosolic defense mechanisms must therefore exist. I will discuss the role of cell-autonomous immunity in defending the cytosol from bacterial invasion, in particular how ‘eat-me’ signals including galectins and ubiquitin become associated with cytosol-invading bacteria, how cells transform the bacterial surface into an anti-bacterial and pro-inflammatory signaling platform, and how cargo-selecting autophagy receptors target cytosolic bacteria for destruction by autophagy.
