Protein misfolding

Tracking a toxic polyQ epitope

The monoclonal antibody 3B5H10 that recognizes diffuse mutant huntingtin predicts cell death in primary striatal neurons. Biochemical and biophysical analyses reveal that the 3B5H10 epitope is exposed in a monomeric state, identifying this specific conformation as a toxic agent in Huntington's disease.
