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
Both Neisseria meningitidis and Moraxella catarrhalis are Gram-negative diplococci which reside in the human nasopharynx. Both species can persist without symptoms, yet on occasion spread from the nasopharynx and cause a range of pathologies. A common feature shared by these bacteria is their ability to interact with members of the carcinoembryonic antigen-related cell adhesion molecule (CEACAM) receptor family. In the case of neisserial species binding occurs via the opacity proteins, whilst M. catarrhalis binds via the ubiquitous surface proteins. The talk will explore the requirements for bacterial ligand-CEACAM interactions and the development of inhibitory molecules.
