The main project is on T cell immunity to Salmonella type and related organisms. Constantino’s group has led the field in developing porin based vaccines and we are currently studying the T cell responses to porins to understand more about their role in immunity against Typhoid and other infections. We are also interested in the role of mucosal associated invariant T cells (MAIT cells) in responses to Salmonellae, how such cells may be activated and their role in gut defence.
Constantino has also been instrumental in setting up studies of B cell immunity in Oxford and contributed to the discovery of LLT-1 as a new marker of germinal centre B cells and activated plasmablasts with Chris Willberg (Llibre et al, JI, 2016). Since LLT-1 binds the MAIT cell ligand CD161, this links the two aspects of research (B cells and T cells) together.
Future studies include the development of novel vaccines for salmonella type, analyses of chronic viral infections in Mexico and further basic science studies to define how long lived antibody responses may be generated. We have had a number of exchange visits for lab members and are keen to develop further collaborative projects in future.
