WELCOME at the DIDO website!!! DIDO is an ERC Advanced Grant Project (ERC-2013-AdG 338954-DIDO) that is  coordinated jointly at the University of Perugia by Prof. Ursula Grohmann  (Principal Investigator; Department of Experimental Medicine) and Prof. Antonio  Macchiarulo (Team Leader; Department of Pharmaceutical Sciences).  The project pools together complementar skillsets and know-how from  multidisciplinary research groups mostly focusing on pharmacology/immunology  and molecular modeling/drug design, with specific regard to indoleamine 2.3 -  dioxygenase 1 (IDO1) biology and IDO1 drug-targeting, thus creating a powerful  platform for significant synergies to achieve the objectives of the project.  Specifically, those are focused on the tryptophan catabolic enzyme IDO1, which  is recognized as an authentic regulator of immunity in several physiopathologic  conditions, including autoimmune diseases, in which it is often defective, and  neoplasia, where it promotes, instead, immune unresponsiveness. Grohmann’s  group recently found that IDO1 does not merely degrade tryptophan and  produce immunoregulatory kynurenines, but it also acts as a signal-transducing  molecule, independently of its enzyme activity. IDO1’s signaling function relies  on the presence of phosphorylable motifs in a region (small IDO1 domain)  distant from the catalytic site (large IDO1 domain). The first objective of DIDO  is to decipher the relationship between conformations and multiple functions of  IDO1. A second aim is to identify small molecules with drug-like properties  capable of modulating distinct IDO1’s molecular conformations in order to either  potentiate (a new therapeutic approach in autoimmune diseases) or inhibit  (more efficient anti-tumor therapeutic strategy) the immunoregulatory signaling  ability of IDO1.     Workshop “Indoleamine2,3-dioxygenase:Interdisciplinary Drug Overview”
