Περίληψη:	Protein misfolding and aggregation are defining features of a wide range of human conditions, collectively termed protein misfolding diseases. These include disorders with diverse pathologies and symptoms, such as Alzheimer’s disease, Parkinson’s disease, and type 2 diabetes, the vast majority of which impose a very high socio-economic burden on humanity and remain incurable to date. To address this unmet medical need, we report here a simple and high-throughput system for identifying macrocyclic rescuers of protein misfolding. In this system, Escherichia coli cells are genetically engineered in order to perform two simultaneous tasks: (1) produce combinatorial libraries of head-to-tail cyclic oligopeptides using protein-splicing technology and (2) enable the identification of the bioactive cyclic peptides that correct the problematic folding and/or inhibit the aggregation of disease-associated misfolding-prone proteins using a genetic assay that links the folding of the target protein to a fluorescent phenotype. In this way, the bioactive cyclic peptide hits are identified in an ultrahigh-throughput manner using flow cytometric cell sorting, thus significantly decreasing the overall cost, time, and complexity of early drug discovery for these notorious diseases.
