  Annual Report

The main objective of our unit is to evaluate the consequences of extensive vaccination of human populations on the microbe targeted by the vaccine, the bacterial ecosystem and the human population in order to propose adapted strategies of prevention and new therapeutic tools to face some of these consequences.

Our unit harbours the National Centre of Reference for Whooping Cough and other bordetellosis theNational Centre of Reference for toxigenic corynebacteria .

The Bordetella teamstudies the bacterial determinants involved in the pathogenicity of the bacteria from the Bordetellagenus, the regulation of the expression of these determinants, the immune responses that they induce in the host, human or animal, after infection, the spatio-temporal evolution of the bacteria and the development of new therapeutical and diagnostic tools. The major observations of 2010 were the influence of herd immunity induced by vaccination with subunit pertussis vaccines, in the control of the virulence of B. pertussis isolates but also B. parapertussisisolates, in contrast to the influence of herd immunity induced by vaccination with whole-cell vaccines.

The Coryne teamhas participated to the development of Multi Locus Sequence Typing technique of C. diphtheriae to replace ribotyping and is currently developing different new identification tools of the species of the diphtheriaecomplex (diphtheriae, ulceransand pseudotuberculosis). Furthermore, we are analyzing the evolution of antibiotic resistances of the corynebacteria of the diphtheriaecomplex.

The protein and antibody engineering teamis studying the mechanisms of neutralization of infectious agents by antibodies at the molecular and atomic levels, and their implications for the development of diagnostic and therapeutic tools. We have undertaken to clarify, through in vitro studies, the complex relations between structure and functions of the Human Ribosomal Protein SA (RPSA), which is a membrane receptor of laminin, prion and re-emerging arboviruses. We have pursued the development of new serological assays for the early serodiagnosis of flavivirus infections, in particular to distinguish between vaccine responses and natural infections. Finally, we have shown that is is possible to create reagentless fluorescent biosensors from any element of natural (e.g. antibodies) or artificial families of antigen binding proteins.

Teaching, training scientists from the net of the Institut Pasteur in order to create National Reference Centres involved in vaccine surveillance, help in case of epidemics and public health activities, were pursued.
