The past few years have seen an efflorescence of information on the 3D structures of virulence factors, toxins, and adhesins of pathogenic bacteria and viruses, as well as of prion and amyloid fibrils. The emergence of this structural information can be attributed to the improved protein expression and crystallization strategies as well as applications of emerging experimental techniques, including cryo-electron microscopy, scanning transmission electron microscopy, solid-state NMR spectroscopy, and electron paramagnetic resonance spectroscopy. It has also become apparent that many polypeptides are “natively” unfolded under physiological conditions, and this class includes precursors to many of the pathogenic proteins outlined above. In addition to the recent revolutionary progress on a conceptual level, this area of research has a vitally important medical dimension related to the fact that the structures of pathogenic folds are key to developing new therapeutics for neurodegenerative disease and infectious diseases of bacterial and viral origins.

This conference will focus on the structures, stability, functions and pathogenicity of these folds as well as strategies for developing therapeutics and vaccines. It will bring together a critical mass of internationally recognized experts who will lead discussions that are intended to distinguish the characteristic structural features of the pathogenic folds, chart their notable diversity, dissect their sequence-structure relationships, and explore novel pathways to drug and vaccine discovery.

In the context of today’s emerging infectious threats and an increasing proportion of the population of the world, which is affected by the age-related neurodegenerative diseases as life-expectancy increases, we anticipate, by organization of this Jacques Monod conference, to generate a large interest among scientific and medical community as well as pharmaceutical companies.

The conference will have four sessions, focussing respectively on:

  1. The structures of virulence- and infectivity-associated proteins of microbial pathogens and their commonality with amyloid and prion fibrils; structure-based strategies of drug and vaccine development.
  2. The process and end-products of amyloidogenesis; new approaches to obtain atomic-level structural details of amyloid fibrils; prediction of amyloidogenic regions in proteins; strategies for the development of inhibitors of fibrillogenesis.
  3. Viral surface proteins; their roles in membrane fusion and infection; survey of structural properties of pathogenic and toxic proteins in general.
  4. The properties of natively unfolded protein regions as precursors of disease-related folds.
