Abstract: The potential of human glucagon-like peptide-1 (hGLP-1) as a therapeutic agent is limited by its high aggregation propensity. We show that hGLP-1 forms amyloid-like structures that are preceded by cytotoxic aggregates, suggesting that aggregation of biopharmaceuticals could present a cytotoxic risk to patients besides the reported increased risk in immunogenicity.
