[Current status and future perspectives in the research of Marfan syndrome].

Marfan syndrome is an autosomal dominant disorder, characterized by tall stature, long arms and legs, ectopia lentis, and aortic aneurysms and dissections. Recent research has revealed that these phenotypes are caused by mutations in fibrillin-1, the major structural component of elastic microfibrils, and the continuing dysregulation of transforming growth factor beta (TGFbeta) signaling is principally considered to be contributing to the pathophysiological background of the disease. Blockade of TGFbeta signaling by angiotensin II receptor antagonism is a novel promising therapeutic option, and thus such large clinical randomized controlled trials are underway. Here, we review the past development, current status and future perspectives in the research field for Marfan syndrome.
