摘要

Plasma protein transthyretin (TTR) can undergo conformational change resulting in the formation of amyloid fibrils that can then cause amyloidosis. This can occur spontaneously in individuals over the age of 70-80 resulting in wild-type transthyretin amyloidosis (ATTR) (with cardiomyopathy). This then progresses to fatal cardiac failure. TTR can also undergo conformational change in individuals who have a genetic abnormality in the structure of TTR resulting in hereditary ATTR amyloidosis. This is usually first manifested as polyneuropathy but can progress to cardiomyopathy with time. Until recently, there has been no specific treatment for these conditions. However, a detailed search for compounds that stabilize TTR resulted in the discovery of tafamidis. This compound stabilizes TTR and has been found to significantly reduce the progression of both wild-type ATTR amyloidosis and hereditary ATTR amyloidosis.
