Lymphatic therapies open the valve in Marfan syndrome

Abstract

Myxomatous degeneration of the mitral valve (MDMV) is a common cardiovascular manifestation of Marfan syndrome (MFS), yet the role of lymphatic vessels in the disease progression remains unknown. In this Commentary, we discuss the study by Tan, Kume, and colleagues, which identifies defective lymphangiogenesis as a previously unrecognized driver of MDMV. Their work demonstrates that impaired lymphatic development and drainage promote valve inflammation through reduced ZFP36-mediated antiinflammatory signaling, whereas restoration of lymphatic function or pharmacological activation of ZFP36 with the FDA-approved drug FTY720 ameliorates disease progression. These findings establish lymphatic vessels as critical regulators of mitral valve homeostasis and support exploration of lymphatic-targeted therapeutic opportunities for MFS-associated valvular disease.

Usage information is collected from two different sources: this site (JCI) and Pubmed Central (PMC). JCI information (compiled daily) shows human readership based on methods we employ to screen out robotic usage. PMC information (aggregated monthly) is also similarly screened of robotic usage.

Various methods are used to distinguish robotic usage. For example, Google automatically scans articles to add to its search index and identifies itself as robotic; other services might not clearly identify themselves as robotic, or they are new or unknown as robotic. Because this activity can be misinterpreted as human readership, data may be re-processed periodically to reflect an improved understanding of robotic activity. Because of these factors, readers should consider usage information illustrative but subject to change.
