Focus

Bacterial systemic infections remain a public health concern in the developed world, Our long term goal is a better understanding of the pathogenesis of these infections in order to identify new targets for prevention and treatment.

Introduction

Systemic infections are characterized by the ability of infecting pathogens to colonize and to disseminate from their port-of-entry into the bloodstream. Two types of bacterial pathogens disseminate beyond their port-of-entry:

  1. the extra cellular pathogens that can survive in the extracellular fluids and have developed attributes that prevent phagocytosis by polymorphonuclear cells and killing by the serum. These bacteria are essentially those responsible for sepsis that remains a life-threatening condition and a major contributor of public health and economic burden in the industrialized world. These pathogens are in direct contact with endothelial cells. Much remain to be understood on the mechanisms and consequences of this bacterial interaction with the capillaries, even though this interaction is a prerequisite for metastatic dissemination (crossing of the blood brain barrier for example).
  2. The intracellular pathogens that disseminate in the body using a Trojan horse such as macrophages. The mechanisms by which these latter pathogens resist to the bactericidal Intracellular environment have long been studied. On the other hand, these pathogens often critically rely on acquisition of host-derived nutrients for the development of a successful infection. Since nutrient availability depends on host metabolism and differs depending on localization within tissues and varies over the course of infection, intracellular pathogens have had to adapt their metabolism to these host metabolic rearrangements.

 

Research objectives

Three main research axes are being pursued.

  • The first approach focuses on the mechanisms and consequences of the interaction of extra-cellular bacterial pathogens with endothelial cells using Neisseria meningtidis as paradigm. This pathogen following bloodstream invasion from the nasopharynx establishes a strong interaction with the capillaries. This interaction is associated with the occurrence of meningitis and Purpura fulminans. Our objectives are to provide a coherent picture of meningococcal pathogenesis by dissecting the interaction between meningococci and endothelial cells at the molecular, cellular, and tissular levels.
  • The second approach consists in deciphering the molecular bases of the host-pathogen metabolic interplay, using two model organisms. (i) Francisella tularensis, a Gram-negative facultative intracellular bacterium, causative agent of the zoonotic disease tularemia. The virulence of this pathogen is linked to its capacity to multiply in the cytosolic compartment of infected macrophages. (ii) Staphylococcus aureus, a Gram-positive pathogen initially classified as strict extracellular bacterium, is now considered as a non-classical facultative intracellular pathogen and its intracellular life style is associated with persistence and relapse. Our objectives are to understand how the metabolism of these bacteria has evolved to adapt to their intracellular niche(s), and to define, at the single cell level, how the metabolism of the host itself is modified in response to the infection.
  • The third axis, “Genomic approaches to microbial pathogenesis and vaccine development” constitute a new theme developed by David Skurnik who joined the team in the fall of 2017. In developed countries, 20% of the bacterial meningitis in neonates is due to Escherichia coli K1. We will use TnSeq to (i) identify and understand the genes and regulatory genetic elements contributing to optimal fitness of E. coli K1 from GI tract colonization, to crossing of the blood brain barrier and, (ii), identify and develop new vaccine candidates via a process we have called TnSeq vaccinology. This approach exploits the TnSeq tool to test the effect of host immunity, induced by vaccination with a broadly-protective immunogen such as antibiotic-killed cells, on selection of strains with Tn-interrupted genes. This approach should impact all types of vaccine antigens, not just proteins, a limitation of current antigen identification systems such as reverse vaccinology.
