Gremlin: vexing VEGF receptor agonist.
Gremlins are mischievous creatures in English folklore, believed to be the cause of otherwise unexplainable breakdowns (the word gremlins is derived from the Old English "gremian" or "gremman," "to vex"). Gremlin (or Gremlin-1) is also the designation of a secreted protein that is known to regulate bone formation during development. In this issue of Blood, Mitola et al report the novel role of Gremlin as a VEGFR2 agonist and the function of the Gremlin protein seems vexing indeed.
