Research description
Surveillance by molecular chaperones may decline, and proteins misfold and self-assemble into amorphous aggregates as well as fibrillar amyloid which are linked to cureless human diseases. Our research aims to understand how molecular chaperones interfere with different types of protein aggregation and alleviate relevant toxicities, and augment specific chaperone capacity for novel treatment developments, in particular against cancer and neurodegenerative diseases. On the other side, non-pathological amyloid is supposed to be shared by spider silk, one of the toughest biomaterials. Currently, our understanding of amyloid-like formation during spider silk assembly process and underlying mechanisms are largely missing.
