Does experimental hypertension produce diverse changes in the regional vascular responses to endothelin-1 in the rabbit and the rat?
The increased responses to endothelin-1 of some variables in the hypertensive animals may involve structural changes in the resistance vessels. However, the reduced responses in the mesenteric vasculature of both species and the renal vasculature of the SHR are due to some mechanism other than structural change.
Mirroring ENX, HMGB1 signaling blockade reduces LEU recruitment, cerebrovascular permeability, and cerebral edema following TBI. ENX further reduced lung edema indicating a multifaceted effect beyond HMGB1 blockade. Further study is needed to determine how ENX may play a role in blunting HMGB1 signaling in brain injury patients.
