By detailed sequence analysis and subsequent biophysical characterization of prototypic light chains, this project aims to identify sequence fingerprints in IGLV1-44 light chains leading to AL amyloidosis and POEMS syndrome. This understanding might help improve the risk stratification and early diagnosis of patients overexpressing pathologic IGLV1-44 LCs. Moreover, the development of nanobodies efficient in recognizing and stabilizing IGLV1-44 light chains which exert direct toxicity in cardiac AL amyloidosis and POEMS syndrome might form the basis for future development of therapeutic agents capable of counteracting IGLV1-44 light chain proteotoxicity.
