However, molecular and cellular mechanisms underlying the role of the Hh signalling in vascular biology remain poorly understood. The purpose of the present article is to clarify some conflicting literature data.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods and results<\/jats:title>\n                  <jats:p>With this goal, we have demonstrated that, unexpectedly, ectopically administered N-terminal Sonic Hh (N-Shh) and endogenous endothelial-derived Desert Hh (Dhh) induce opposite effects in endothelial cells (ECs). Notably, endothelial Dhh acts under its full-length soluble form (FL-Dhh) and activates Smoothened in ECs, while N-Shh inhibits it. At molecular level, N-Shh prevents FL-Dhh binding to Patched-1 (Ptch1) demonstrating that N-Shh acts as competitive antagonist to FL-Dhh. Besides, we found that even though FL-Hh ligands and N-Hh ligands all bind Ptch1, they induce distinct Ptch1 localization. Finally, we confirmed that in a pathophysiological setting, i.e. brain inflammation, astrocyte-derived N-Shh acts as a FL-Dhh antagonist.<\/jats:p>\n               <\/jats:sec>\n
