Abstract: The present invention provide purified Flt4 receptor tyrosine kinase polypeptides and fragments thereof, polynucleotides encoding such polypeptides, antibodies that specifically bind such polypeptides, and uses therefor.

Abstract: VEGF-D, a new member of the PDGF family of growth factors, which among other things stimulates endothelial cell proliferation and angiogenesis and increases vascular permeability, as well as nucleotide sequences encoding it, methods for producing it, antibodies and other antagonists to it, transfected or transformed host cells for expressing it, pharmaceutical compositions containing it, and uses thereof in medical and diagnostic applications.

Abstract: Provided are purified and isolated VEGF-C polypeptides capable of binding to at least one of KDR receptor tyrosine kinase (VEGFR-2) and Flt4 receptor tyrosine kinase (VEGFR-3); analogs of such peptides that have VEGF-C-like or VEGF-like biological activities or that are VEGF or VEGF-C inhibitors: polynucleotides encoding the polypeptides: vectors and host cells that embody the polynucleotides; pharmaceutical compositions and diagnostic reagents comprising the polypeptides; and methods of making and using the polypeptides. Methods of inhibiting endothelial cell proliferation are also provided.

Abstract: The invention relates to a method of treatment of pulmonary edema, comprising the step of administering to a subject in need thereof a therapeutically effective amount of an agent capable of inhibiting signaling mediated by VEGFR-3, inhibiting lymphangiogenesis or inhibiting VEGF-D activity in the subject. The method may comprise the step of identifying a subject at risk of developing pulmonary edema. The invention also relates to an agent capable of inhibiting signaling mediated by VEGFR-3, inhibiting lymphangiogenesis, or inhibiting VEGF-D activity for treating pulmonary edema in a subject. Further, the invention relates to use of an agent capable of inhibiting signaling mediated by VEGFR-3, inhibiting lymphangiogenesis, or inhibiting VEGF-D activity in the manufacture of a medicament for treating pulmonary edema in a subject.
