Dexmedetomidine attenuates endoplasmic reticulum stress-induced apoptosis and improves neuronal function after traumatic brain injury in mice

Traumatic brain injury (TBI) is one of the leading causes of mortality and disability worldwide. Emerging studies have shown that endoplasmic reticulum (ER) stress plays an important role in the pathophysiology of TBI. Dexmedetomidine (Dex), a highly selective α2-adrenoreceptor agonist, has been shown to attenuate ER stress. However, there is no relevant research in the field of TBI. To study the effects of dexmedetomidine on TBI, we subjected...
