Background: Extracellular amyloid deposits involve glycosaminoglycans (GAGs). Results: Fibrillation of AL proteins was accelerated by heparan sulfate and inhibited by chondroitin sulfate A. Conclusion: Endogenous GAGs can modulate amyloid formation, and their effect is determined by the amyloidogenic properties of AL proteins studied. Significance: Biologically relevant molecules like GAGs play a major role in the amyloidogenicity of AL proteins.
