Research Summary

Research in the Lazo Lab is focused on the biophysics of misfolding and self-assembly of proteins associated with disease. Proteins of interest include the amyloid β-protein in Alzheimer's disease, islet amyloid polypeptide associated with type 2 diabetes, the prion protein in various forms of prionoses, and skin proteins linked to epidermolysis bullosa, a disease characterized by skin blistering following little or no trauma. A combination of biophysical and biochemical methods including NMR spectroscopy and limited proteolysis/mass spectrometry is used to elucidate the early events of protein misfolding and self-assembly.
