Published in: ASC Omega
The exploitation of curcumin for oral disease treatment is limited by its low solubility, poor bioavailability, and low stability. Surface-functionalized poly-lactic-co-glycolic acid (PLGA) nanoparticles (NPs) have shown promising results to ameliorate selective delivery of drugs to the gastrointestinal tract. [...]

Publication year: 2019
Authors: Antonella Managò1,12, Valentina Audrito1,12, Francesca Mazzola2, Leonardo Sorci 3, Federica Gaudino1, Katiuscia Gizzi4, Nicoletta Vitale5, Danny Incarnato6, Gabriele Minazzato7, Alice Ianniello8, Antonio Varriale9, Sabato D’Auria9, Giulio Mengozzi8, Gianfranco Politano 10, Salvatore Oliviero 4,11, Nadia Raffaelli7,13 & Silvia Deaglio 1,13
Published in: Nature communications
Damage-associated molecular patterns (DAMPs) are molecules that can be actively or passively released by injured tissues and that activate the immune system. Here we show that nicotinate phosphoribosyltransferase (NAPRT), detected by antibody-mediated assays and mass spectrometry, is an extracellular ligand for Toll-like receptor 4 (TLR4) and a critical mediator of inflammation, acting as a DAMP. Exposure of human and mouse macrophages to NAPRT activates the inflammasome and NF-κB for secretion of inflammatory cytokines. [...]
