2001-2014: member of various Scientific Councils in Europe.
2004-2010: Deputy Director of the Scuola Galileiana of Padova
1998-on: members of the Editorial Boards of several peer-reviewed scientific journals
Performed research stages at: Institut Pasteur, Paris (1984 with J.P. Changeux and 2002 with M. Mock), University of Utrecht (1990 with Ben de Kruijff), EMBL in Heidelberg (1997 with M. Zerial), Universidad de Costa Rica (2008 with JM Gutierrez).
Prof. C. Montecucco studies the mechanisms of action of presynaptic protein neurotoxins that cause neuroparalysis and the inter-and intra-cellular signalling events that drive regeneration after peripheral neuroparalysis in mammals.
1986. Proposed the double "protein-and-glycolipid" model for the binding of tetanus and botulism neurotoxins to nerve terminals. This model is now fully supported by the 3D structures of the receptor binding domains of tetanus and botulinum neurotoxins.
1986-1988. Identification of active site residues of diphtheria toxin.
1987: Proposed the “cleft model” for the membrane translocation of bacterial protein toxins with intracellular targets. A similar model has been proven in 1995 for the ER translocon.
1991: discovered the zinc-endopeptidase activity of tetanus and botulinum neurotoxins
1992-1995: identified the intraneuronal targets and peptide bond specifity of tetanus and botulinum neurotoxins. This was the first and strongest demonstration of the essential role of VAMP/synaptobrevin, SNAP-25 and syntaxin in the release of neurotransmitters, and in exocytosis in general.
1993: Provided evidence that the different sensitivity of animal specifies to tetanus and botulism type B may be due to mutation of VAMP at the site of proteolytic cleavage.
1994: bacterial toxins with intracellular activity enter cells via a four-step mechanism. All the present available experimental evidence fit in this model.
1994: Identified the SNARE motif as a major determinant in the specific recognition of the three SNARE proteins by tetanus and botulinum neurotoxins.
1993-1998: Discovered the acid activation of the VacA cytotoxin of H. pylori, the late endosomal/prelysosomal nature of the vacuoles induced by the VacA and determined some immunological and pathological consequences of the alterations of membrane trafficking at the level of late endosomes, such as the inhibition of antigen processing and of the invariant chain dependent antigen presentation. Discovered that VacA induces a specific change of the trans-epithelial resistance of epithelial cell monolayers.
1996-1999: discovered that VacA toxin forms anion specific channels in planar lipid bilayers and on cells.
1999-2000: Identified the neutrophil activating protein of H. pylori (HP-NAP) as a major antigen in the human response and determined its structural, biochemical and cell activation properties.
The results obtained with VacA and HP-NAP lead to the present formulation of an anti-H. pylori vaccine, containing CagA, VacA and HP-NAP, currently under clinical trial. Phase I and II clinical trials show that this vaccine is non toxic and it is highly immunogenic.
1998-2000: co-discovered that the anthrax lethal factor is a zinc-endopeptidase specific for the MAPK kinases, which are cleaved within their N-terminus and identified the cleavage consensus motif.
2002: development of a high throughput assay of the metalloproteolytic activity of the Anthrax Lethal Factor and identified useful inhibitors.
2005: discovered the mechanism of action of the presynaptic snake PLA2 neurotoxins
2010-13: discovery that snake venom myotoxins cause entry of Ca and release of K and ATP from muscle cells and that ATP and mitochondrial components act as ALARMINS
2012-13: elaborated the mode of entry into neurons of the botulinum neurotoxins
2005-2013: developed a radial model for the nanomachine that mediates neurotransmitter release at the synapse and provided some experimental evidence.
2013: showed that ATP is involved in the immune adjuvant effect of MF59
2013-14: discovered that thioredoxin reductase and thioredoxin are present on the cytosolic surface of synaptic vesicles and that they mediate the release of tetanus and botulinum neurotoxin light chains in the cytosol. Identified several novel botulinum neurotoxin inhibitors.
