At the moment, I'm reading The role of molecular chaperones in human misfolding diseases [PDF] by Sarah A. Broadley and F. Ulrich Hartl of the Max Planck Institute of Biochemistry. It's a good overview of the subject, with 107 references, mostly from 2002 on.
Anxious to look at several other papers, in particular:
