Addressing one of the biggest riddles in current molecular cell biology, this ground–breaking monograph builds the case for the crucial involvement of lipids and membranes in the formation of amyloid deposits. Tying together recent knowledge from in vitro and in vivo studes, and built on a sound biophysical and biochemical foundation, this overview brings the reader up to date with current models of the interplay between membranes and amyloid formation.

Required reading for any researcher interested in amyloid formation and amyloid toxicity, and possible avenues for the prevention or treatment of neurodegenerative disorders.
