Tuberculosis is one of the most threatening infectious diseases worldwide due to the low efficiency of the only licensed anti-tuberculosis vaccine, BCG. This project aims to interrogate two previously neglected immune mechanisms and their potential to enhance vaccine-induced immunity by incorporating these mechanisms into new genetically modified BCG strains. We will also investigate alternative BCG vaccination routes to generate long-lived immune cells that can rapidly control the infection.
The Glyco-interactome Of Pathogenic Neisseria: Understanding Disease And Defining Vaccine Targets

Summary
In order to infect humans and cause disease, many bacteria rely on interactions with carbohydrate (sugar) structures on human cells. This project aims to characterise the sugar interactions that enable Neisseria meningitidis (causes meningitis, sepsis) and Neisseria gonorrhoeae (causes gonorrhoea, associated with infertility and increased transmission of HIV) to cause disease. This will increase our understanding of host-pathogen interactions and aid development of new vaccines and therapeutics.
Role In Disease Of A Novel Epigenetic Regulator Associated With The Hypervirulent Neisseria Meningitidis Clonal Complex 41/44

Summary
Neisseria meningitis is a major cause of meningococcal septicaemia and meningitis worldwide. We have identified a phase variable DNA methyltransferase present in disease isolates, some of which have caused meningococcal epidemics. This methyltransferase is involved in the regulation of proteins involved in infection and disease processes. We will investigate whether this regulation increases the ability of the bacteria to adapt to changing host environments and cause disease.
