Mitochondrial Function in Transthyretin Amyloidosis

Hereditary (familial) amyloidosis arising from the misfolding of a mutated or variant transthyretin, is the most frequent form of amyloid cardiomyopathy in the Caribbean basin. Affected organs invariably harbor extracellular amyloid deposits in the myocardium. Circulating or pre-fibrillar amyloidogenic proteins are implicated in the disruption of cell function. The investigators aim is to demonstrate that transthyretin mediated amyloid disease alter the mitochondrial function of cardiac cells.
