OxTalks will soon be transitioning to Oxford Events (full details are available on the Staff Gateway). A two-week publishing freeze is expected in early Hilary to allow all events to be migrated to the new platform. During this period, you will not be able to submit or edit events on OxTalks. The exact freeze dates will be confirmed as soon as possible.
If you have any questions, please contact halo@digital.ox.ac.uk
Cells require nutrient metal to carry out essential biochemical processes. This requirement is something that the immune system has exploited to defend against infection by restricting microbial access to metal. This process of nutrient restriction during infection is called “nutritional immunity”. Bacterial pathogens evolved elaborate mechanisms to circumvent nutritional immunity and acquire metal during infection. This struggle for nutrient metal impacts microbial virulence as well as the immune response of the host, profoundly impacting the outcome of host-pathogen interactions. In this talk I will cover aspects of nutritional immunity and microbial countermeasures that are relevant to infectious diseases.
