2019 to present: Formal collaboration (Membership) with CNR (National Research Council), Institute of Applied Sciences & Intelligent Systems-ISASI, Pozzuoli (Naples)

Main results obtained:

(i) Studies on the molecular mechanism of action of plant ribosome-inactivating proteins (RIPs): identification of the cellular tRNAs involved in the stimulation of RIPs, identification of the tRNA identity elements required (1989-2001);

(ii) Studies on the molecular mechanism of action of specific bacterial toxins namely Shiga toxins: demonstration of the damaging effect of these toxins on nuclear DNA in human endothelial cells, discovery of small ring compounds inhibiting the enzymatic activity of these toxins, demonstration of the inhibitory effect of the toxins on DNA repair (1997-2007).

(iii) Studies on the pathogenesis of hemolytic uremic syndrome (HUS) caused by Shiga toxin-producing E. coli strains (VTEC/STEC): set up of rapid methods for the detection of Shiga toxins bound to neutrophils (indirect flow cytometric analysis) or free in sera (inhibition of translation in Raji cells) of patients. We have recently identified the Toll-like receptor 4 as the membrane molecule of human neutrophils that recognizes Shiga toxins. Moreover, the antibiotic polymyxin b, as well as the non-toxic derivative NAB815, were found to inhibit the interactions of Shiga toxins with TLR4 on neutrophils and the related functional consequences. Finally, the structure of Shiga toxins (holotoxin or nicked toxin) dictates the interactions of the toxins with blood components; i.e. binding to neutrophils (only holotoxin), activation of the complement system (nicked toxin). Recent findings have provided additional elements to foster the understanding of the pathophysiology of HUS. By comparing patients developing HUS and patients who recovered, we have found Shiga toxin 2 bound to circulating cells and then appearing in blood in particulate form, as in the case of extracellular vesicles, allowing the triggering of HUS. Finally, we have developed and patented the drug NAB815 which is capable of impairing the release of pathogenic microvesicles in human blood treated with Shiga toxin 2, thus blocking their toxic effects in cellular and animal models (2004-2023).

iv) Studies on the molecular pathology of ribosomes and protein synthesis. The methods employed in the studies on the effect of bacterial toxins on nucleic acids and ribosomes (see above) have been used to pursue other topics in collaboration with different research teams: effect of hyperosmolar stress on protein synthesis in vitro, protective effect of deuterated amino acids against oxidative damage in proteins, structural and functional alterations of ribosomes in cancer. A new protocol describing the isolation of stringently purified ribosomes from human cells for evaluating efficiency and fidelity of cis-acting elements mediated-translation in vitro has been developed and published on Nature Protocols (2003-2023).
