Essentials facts about VEGF-C in lymphology

Vascular endothelial growth factor C (VEGF-C) is essential for the development and growth of the lymphatic vasculature. Together with VEGF-D, it forms the lymphatic subgroup within the VEGF family of growth factors, whose other members (PlGF, VEGF/VEGF-A, VEGF-B) are primarily responsible for the growth and function of blood vessels. VEGF-C was discovered as a ligand of the tyrosine kinase receptor VEGFR-3 (1) and its specific effect on lymph vessels was first described in 1997 (2,3). About one-third of hereditary lymphedema cases in humans result from mutations in genes involved in VEGF-C signaling (4). The complete absence of VEGF-C leads to death during embryogenesis (5). Likely for this reason, clinical cases of hereditary lymphedema are characterised by a partial inactivation of the signal transduction. VEGFR-3 (6) is affected in most cases, but mutations of the hereditary lymphedema are described or suspected for all components of the VEGF-C signal transduction described below, partly within a multifactorial inheritance.
