The systemic amyloidoses: clearer understanding of the molecular mechanisms offers hope for more effective therapies.

Knowledge about the systemic amyloidoses has increased considerably during the last few years. This group of diseases is characterized by great biochemical variability, including at least 11 different amyloid fibril proteins and a remarkable range of clinical manifestations. With the understanding that the pathogenesis is different in the various forms of amyloidosis, it is now being increasingly accepted that an early and accurate diagnosis, including that of the underlying biochemical nature, is crucial for a successful treatment. The elucidation of the molecular mechanisms involved in amyloidogenesis is at the basis of the recent blossoming of new, innovative and more effective therapeutic approaches.
