Neuropilins and Semaphorins

Our investigations started with the question, why are there so many VEGF isoforms? One possibility that was considered was that some isoforms may interact with receptors other than VEGFR1 and VEGFR2, the only VEGF receptors known at that time. Cross-linking studies using labeled VEGF165 and human umbilical vein endothelial cells (HUVEC) revealed two crosslinking products that were missing in cr...
