The Service Immunology was originally part of the Pasteur Institute of Brussels and was integrated in the Scientific Institute of Public Health in 2007. The activities of the service were initially focused on Mycobacterial Immunology and Vaccinology (M.tuberculosis, M. ulcerans and M. avium ssp. paratuberculosis) and have been extended more recently to research on Mould allergy. The service is also partner in the National Reference Centre for Bordetella pertussis since 2011 and involved in serosurveillance studies of vaccine preventable diseases. The service has played a pioneering role in the identification of protective antigens of TB, more in particular the Ag85 family of mycolyl-transferases.
Kris Huygen (PhD), created the service in the mid-eighties and has been involved since in research on mycobacterial infections. In a Nature Medicine paper, she demonstrated the protective role of Ag85A using plasmid DNA vaccination (1996)
Olivier Denis (PhD) joined the lab in 1995 and was actively involved in the characterization of CD4+ and particularly CD8+ T cell epitopes in DNA vaccinated mice.
Marta Romano (PhD) joined the lab in 2001. Her work published in J Immunology in 2004 showed for the first time the induction of in vivo functional Db restricted cytolytic T cells against the protective antigen PstS-3 (Rv 0928), a putative phosphate transport receptor.
Nicolas Bruffaerts worked on his PhD thesis with financing of the FP7 funded NEWTBVAC project. His work showed that a combination of coding plasmid DNA with M. bovis BCG can increase the CD4+ and CD8+ potential of the latter vaccine. In a PLoS One paper of 2015 he showed that this combination is effective, not only in mice but also in a large mammalian species i.e. Sus scrofa (pig)
Giresse Tima is the PhD student, who since 2013 is involved in the study of the inflammatory and adjuvant properties of synthetic mycolic acid esters. This work is performed in collaboration with Prof. Marc Baird (Bangor University, Wales UK) and Johan Grooten (UGent, Belgium) and is partially financed by the TBVAC 2020 consortium.
