Understanding how a protein called VEGFR3 affects lymphatic vessels

VEGFR Signaling Controls Lymphatic Junctions

NIH-funded research University of South Florida · NIH-11118863

What this research studies

Congenital lymphedema is a condition where inherited gene changes cause swelling in the limbs, often leading to disfigurement and infections. One common cause is a change in the VEGFR3 gene, which leads to Milroy's disease, but we don't fully understand how this gene affects lymphatic vessels. Our team is using a special mouse model where we can study the VEGFR3 gene specifically in lymphatic vessels. We've found that losing VEGFR3 affects how these vessels remodel their connections, which are crucial for fluid drainage. By understanding these basic functions, we hope to uncover why Milroy's disease develops and pave the way for new treatments.

Who could benefit from this research

Good fit: This foundational research is most relevant to patients with congenital lymphedema, particularly those with Milroy's disease caused by VEGFR3 gene mutations.

Not a fit: Patients without lymphatic conditions or those not directly affected by VEGFR3-related lymphedema may not directly benefit from this specific basic research.

Why it matters

Potential benefit: If successful, this research could lead to the development of new drug therapies for congenital lymphedema, including Milroy's disease.

How similar studies have performed: While VEGFR3's role in lymphatic vessel formation is known, this research explores its physiological functions, which are largely unknown, making this a novel approach to understanding Milroy's disease.
