Glycation potentiates α-synuclein-associated neurodegeneration in synucleinopathies. Brain. 2017 May 1;140(5):1399-1419. PMID: 28398476.

From the abstract: "α-Synuclein misfolding and aggregation is a hallmark in Parkinson's disease and in several other neurodegenerative diseases known as synucleinopathies. ... Combining molecular genetics with target-based approaches, we established that glycation, an unavoidable age-associated post-translational modification, enhanced α-synuclein toxicity in vitro and in vivo, in Drosophila and in mice. ... Altogether, our study demonstrates glycation constitutes a novel drug target that can be explored in synucleinopathies as well as in other neurodegenerative conditions."
