TL;DR: The discovery of a negative regulator acting on Tie2 emphasizes the need for exquisite regulation of this angiogenic receptor system.

TL;DR: It is shown that mice engineered to lack Angiopoietin-1 display angiogenic deficits reminiscent of those previously seen in mice lacking TIE2, demonstrating that AngiopOietIn-1 is a primary physiologic ligand for TIE1 and that it has critical in vivo angiogenesis actions that are distinct from VEGF and that are not reflected in the classic in vitro assays used to characterize VEGf.

TL;DR: The identification of a secreted ligand for TIE2, termed Angiopoietin-1, is reported using a novel expression cloning technique that involves intracellular trapping and detection of the ligand in COS cells.

TL;DR: The identification of ligands for Tyro 3 and Axl (alternatively, Ark or UFO), members of a previously orphan family of receptor-like tyrosine kinases, correspond to protein S, a protease regulator that is a potent anticoagulant, and Gas6, a protein related toprotein S but lacking any known function.

TL;DR: A neurotrophin is isolated from both human and rat genomic DNA that appears to represent the mammalian counterpart of Xenopus/viper NT-4, which has many unusual features compared to the previously identified neurotrophins and is less conserved evolutionarily than the other neurotrophs.
