Abstract
BACKGROUND Pyroptosis is a programmed cell death mediated by inflammasomes. Previous studies have reported that inhibition of neurokinin receptor 1 (NK1R) exerted neuroprotection in several neurological diseases. Herein, we have investigated the role of NK1R receptor inhibition using Aprepitant to attenuate NLRC4-dependent neuronal pyroptosis after intracerebral hemorrhage (ICH), as well as the underlying mechanism. METHODS A total of 182 CD-1 mice were used. ICH was induced by injection of autologous blood into the right basal ganglia. Aprepitant, a selective antagonist of NK1R, was injected intraperitoneally at 1 h after ICH. To explore the underlying mechanism, NK1R agonist, GR73632, and protein kinase C delta (PKCδ) agonist, phorbol 12-myristate 13-acetate (PMA), were injected intracerebroventricularly at 1 h after ICH induction, and small interfering ribonucleic acid (siRNA) for NLRC4 was administered via intracerebroventricular injection at 48 h before ICH induction, respectively. Neurobehavioral tests, western blot, and immunofluorescence staining were performed. RESULTS The expression of endogenous NK1R and NLRC 4 were gradually increased after ICH. NK1R was expressed on neurons. Aprepitant significantly improved the short- and long-term neurobehavioral deficits after ICH, which was accompanied with decreased neuronal pyroptosis, as well as decreased expression of NLRC4, Cleaved-caspase-1, GSDMD (gasdermin D), IL-1β, and IL-18. Activation of NK1R or PKCδ abolished these neuroprotective effects of Aprepitant after ICH. Similarly, knocking down NLRC4 using siRNA produced similar neuroprotective effects. CONCLUSION Aprepitant suppressed NLRC4-dependent neuronal pyroptosis and improved neurological function, possibly mediated by inhibition of NK1R/PKCδ signaling pathways after ICH. The NK1R may be a promising therapeutic target for the treatment of ICH.

Abstract
Hematoma clearance is an important therapeutic target to improve outcome following intracerebral hemorrhage (ICH). Recent studies showed that Neurokinin receptor-1 (NK1R) inhibition exerts protective effects in various neurological disease models, but its role in ICH has not been explored. The objective of this study was to investigate the role of NK1R and its relation to hematoma clearance after ICH using an autologous blood injection mouse model. A total of 332 adult male CD1 mice were used. We found that the expression levels of NK1R and its endogenous ligand, substance P (SP), were significantly upregulated after ICH. Intraperitoneal administration of the NK1R selective antagonist, Aprepitant, significantly improved neurobehavior, reduced hematoma volume and hemoglobin levels after ICH, and promoted microglia polarization towards M2 phenotype. Aprepitant decreased phosphorylated PKC, p38MAPK, and NFκB p65, and downregulated M1 markers while upregulating M2 markers after ICH. Intracerebroventricular administration of the NK1R agonist, GR73632 or PKC agonist, phorbol 12-myristate 13-acetate (PMA) reversed the effects of Aprepitant. To demonstrate the upstream mediator of NK1R activation, we performed thrombin injection and found that it increased SP. Inhibiting thrombin suppressed SP and decreased M1 markers while increasing M2 microglia polarization. Thus, NK1R inhibition promoted hematoma clearance after ICH by increasing M2 microglial polarization via downregulating PKC/p38MAPK/NFκB signaling pathway, and thrombin may be a key upstream mediator of NK1R activation. Therapeutic interventions inhibiting NK1R signaling may be a new target for the treatment of ICH.

Abstract
Discovered in 1987 as a potent endothelial cell-derived vasoconstrictor peptide, endothelin-1 (ET-1), the predominant member of the endothelin peptide family, is now recognized as a multifunctional peptide with cytokine-like activity contributing to almost all aspects of physiology and cell function. More than 30 000 scientific articles on endothelin were published over the past 3 decades, leading to the development and subsequent regulatory approval of a new class of therapeutics-the endothelin receptor antagonists (ERAs). This article reviews the history of the discovery of endothelin and its role in genetics, physiology, and disease. Here, we summarize the main clinical trials using ERAs and discuss the role of endothelin in cardiovascular diseases such as arterial hypertension, preecclampsia, coronary atherosclerosis, myocardial infarction in the absence of obstructive coronary artery disease (MINOCA) caused by spontaneous coronary artery dissection (SCAD), Takotsubo syndrome, and heart failure. We also discuss how endothelins contributes to diabetic kidney disease and focal segmental glomerulosclerosis, pulmonary arterial hypertension, as well as cancer, immune disorders, and allograft rejection (which all involve ETA autoantibodies), and neurological diseases. The application of ERAs, dual endothelin receptor/angiotensin receptor antagonists (DARAs), selective ETB agonists, novel biologics such as receptor-targeting antibodies, or immunization against ETA receptors holds the potential to slow the progression or even reverse chronic noncommunicable diseases. Future clinical studies will show whether targeting endothelin receptors can prevent or reduce disability from disease and improve clinical outcome, quality of life, and survival in patients.

Abstract
The effects of R-type calcium channels on cerebral blood flow (CBF) and vasospasm pathways following subarachnoid hemorrhage (SAH) have not been well studied. The aim of this study was to investigate the role of R-type calcium channels in vasospasm development and treatment. Sixty-five rats were randomly divided into four groups: sham (n = 14), SAH (n = 17), SAH + nimodipine (n = 17), and SAH + SNX-482 (n = 17). A prechiasmatic SAH model was constructed on day 0. Then 5 μg of nimodipine (an L-type calcium channel antagonist) or 0.1 μg of SNX-482 (an R-type calcium channel antagonist) was infused intracisternally on days 1 and 2. On day 3, neurological status was evaluated and CBF was determined using fluorescent microspheres. The extent of myosin light chain-2 (MLC2) phosphorylation was determined by urea-glycerol polyacrylamide gel electrophoresis, followed by immunoblotting. The relative presence of R-type calcium channels and calponin was determined by SDS polyacrylamide gel electrophoresis, followed by immunoblotting. Numbers of R-type calcium channels increased following SAH, and neurological deficit, CBF reduction, and enhancement of MLC2 phosphorylation as well as calponin degradation were all found to be present. There were no statistically significant differences in neurological scores among the SAH, SAH + nimodipine, and SAH + SNX-482 groups. Nimodipine had no significant effect on CBF reduction compared to the SAH group (p > 0.008), whereas SNX-482 significantly inhibited CBF reduction (p < 0.008). Both MLC2 phosphorylation and calponin degradation appeared to be inhibited by SNX-482, whereas the effects of nimodipine were relatively blunted. We concluded that an R-type calcium channel antagonist may improve CBF following SAH by partially inhibiting MLC2 phosphorylation and calponin degradation, and may exceed the potential of an L-type calcium channel antagonist, which suggests a more crucial role for R-type calcium channels in the development of SAH vasospasm and its treatment.

Abstract
OBJECTIVE The present study aimed to investigate the expression of COMT mRNA and protein and detect the plasma content of catecholamine (CA), the diameter and thickness of the basilar artery in the early stage of subarachnoid hemorrhage (SAH) to explore the role of COMT in SAH. METHODS SAH was induced by injection of nonheparinized autologous arterial blood into the chiasmatic cistern. RT-PCR and Western blotting were used to detect the mRNA and protein levels of COMT in the rat striatum at different time points (6, 12, 24, 48, and 72 h after SAH). High performance liquid chromatography was performed to detect plasma CA. With HE staining, the basilar artery diameter and its thickness were measured. RESULTS Compared with the normal group and sham group, the increased expression of mRNA and protein of COMT began at 6 h after SAH (P<0.01), which peaked at 12 h (P<0.01); it began to drop 24 h after SAH (P<0.01). However, 48 h after SAH, the level of COMT (mRNA and protein) was still higher than that of the normal group (P<0.01). Three days after SAH, the expression of COMT nearly reached normal levels (P>0.05). For rats undergoing SAH, plasma CA began to increase 6h after injury, which reached a maximum at 24 h after SAH, and then started to drop. Three days later, it still remained elevated compared with that of the normal group and sham group (P<0.01). The most marked contraction and increased wall thickness of the basilar artery were found at 24 h after SAH (P<0.01), which at least lasted for 2 days (P<0.01), and 72 h after injury, the diameter and thickness of the basilar artery almost reached normal levels (P>0.05). CONCLUSION (1) SAH could induce the expression of COMT in the rat striatum in the early stage. (2) Plasma CA levels were significantly elevated in the early stage of SAH accompanied by cerebrovascular vasospasm (CVS). (3) In the early stage of SAH, increased plasma and CVS may be associated with the insufficient increase and persistence of COMT expression.

Abstract
Migraine and anxiety disorders are frequently co-morbid with balance disorders. This study examined the relative distribution of subtypes of serotonin (5-HT) receptor in the inner ear of monkeys and rats. Most vestibular ganglion cells were immunoreactive for 5-HT(1B) and 5-HT(1D) receptors in macaques and rats. In the inner ear, 5-HT(1B) and 5-HT(1D) receptor immunopositivity was associated with endothelial cells of the vestibular ganglion, spiral ganglion, vestibulocochlear nerve, spiral ligament and stria vascularis. It was noteworthy that 5-HT(1B) and 5-HT(1D) receptors are expressed in parallel sites in peripheral vestibular and trigeminal systems, which may be a factor underlying the efficacy of triptans in treating migraine and migrainous vertigo. Because the vestibular ganglion and trigeminal ganglion are both within the subarachnoid space, an interaction between 5-HT(1B) and TRPV1 receptors on blood vessel and ganglion cells may also contribute to the vasospasm and the comorbid headache, dizziness, nausea and vomiting that accompany subarachnoid hemorrhage.

Inhibition of cerebral vasoconstriction by dantrolene and nimodipine. Neurocrit Care 2008; 10:93-102.

Abstract
INTRODUCTION Cerebral vasoconstriction is associated with increased cytosolic Ca(2+) concentration in vascular smooth muscle, presumably due to Ca(2+) influx and Ca(2+) release from intracellular stores. We tested the hypothesis that dantrolene (a blocker of Ca(2+)-induced Ca(2+) release from the ryanodine receptor channel on the sarco-endoplasmic reticulum) would potentiate the action of nimodipine (a voltage-dependent L-type Ca(2+) channel blocker, considered standard therapy for SAH) in inhibiting the vasoconstriction of isolated cerebral arteries. METHOD Sprague-Dawley rat basilar and femoral arteries were analyzed for ryanodine receptor expression by immunofluorescence and PCR. Vasoconstriction of basilar artery ex vivo was measured in a wire myograph while exposed to serotonin (5-HT) or endothelin-1 (ET-1) in the presence or absence of dantrolene (10-100 muM) and/or nimodipine (30 nM). Femoral artery was examined for comparison. RESULTS Basilar and femoral arteries express only the ryanodine receptor 3 (RyR3) isoform. In both basilar and femoral arteries, dantrolene significantly inhibited the constriction to 5-HT, whereas it poorly affected the constriction to ET-1. The inhibitory effect of dantrolene on 5-HT was substantially increased by nimodipine, inducing a 10-fold increase in the 50% effective concentration of 5-HT and a 46% reduction in maximum basilar constriction. In femoral artery, dantrolene modestly affected constriction to phenylephrine and there was no interaction with nimodipine. CONCLUSION Dantrolene has synergistic effects with nimodipine against 5-HT-induced vasoconstriction in isolated cerebral arteries. Dantrolene-nimodipine interaction will require testing in a pathophysiological model but might provide treatment for reducing SAH-related vasospasm or other 5-HT-related vasospastic syndromes, such as Call-Fleming syndrome.
