Abstract
As we all know, dexmedetomidine (DEX), as a highly selective α2 adrenergic receptor agonist, exerts sedative, anti-anxiety and hypnotic effects by inhibiting the discharge of norepinephrine neurons in locus coeruleus and GABA-related hypnotic pathways. However, the role of DEX in anti-inflammatory and immune regulation has gradually attracted the attention of researchers in recent years. The α2 adrenergic receptor is one of the members of the adrenergic receptor family, which is widely present in a variety of immune cells and mediates the biological behavior of the inflammatory immune system. At present, there have been more and more studies on the effects of DEX on immune cells and inflammatory responses, but few studies have systematically explored the anti-inflammatory and immunomodulatory effects of DEX. Here, we comprehensively review the published human and animal studies related to DEX, summarize the effects of DEX on immune cells and its role in related diseases, and propose potential research direction.

Clonidine restores vascular endothelial growth factor expression and improves tissue repair following severe trauma. Am J Surg 2017; 214:610-615.

Abstract
BACKGROUND We hypothesized that clonidine and propranolol would increase VEGF and VEGF-receptor expression and promote lung healing following severe trauma and chronic stress. METHODS Sprague-Dawley rats were subjected to lung contusion (LC), lung contusion/hemorrhagic shock (LCHS), or lung contusion/hemorrhagic shock/daily restraint stress (LCHS/CS). Clonidine and propranolol were administered daily. On day seven, lung VEGF, VEGFR-1, VEGFR-2, and HMGB1 were assessed by PCR. Lung injury was assessed by light microscopy (*p < 0.05). RESULTS Clonidine increased VEGF expression following LCHS (43%*) and LCHS/CS (46%*). Clonidine increased VEGFR-1 and R-2 expression following LCHS/CS (203%* and 47%*, respectively). Clonidine decreased HMGB1 and TNF-alpha expression following LCHS/CS (22%* and 58%*, respectively.) Clonidine decreased inflammatory cell infiltration and total Lung Injury Score following LCHS/CS. Propranolol minimally affected VEGF and did not improve lung healing. CONCLUSIONS Clonidine increased VEGF and VEGF-receptor expression, decreased HMGB1 expression, decreased lung inflammation, and improved lung tissue repair.

Abstract
Two non-sulfur containing ACE-inhibitors were tested concerning their local effect on experimental dermatitis in ovalbumin-sensitized guinea pigs. Enalaprilat but not cilazaprilat potentiated the ovalbumin-evoked inflammatory response. Furthermore, enalaprilat clearly enhanced the erythema evoked by substance P, whereas cilazaprilat did not. Concerning, the bradykinin-evoked erythema, enalaprilat significantly potentiated the response, whereas cilazaprilat only caused a slight increase. Our results suggest that different affinities for peptidases involved in degradation of inflammatory peptides can explain differences between the pro-inflammatory properties of enalaprilat and cilazaprilat.
