the dorsal periaqueductal grey matter (dPAG) inhibits escape, a panic-related defensive behaviour. dpag 124-128 5-hydroxytryptamine receptor 1A Rattus norvegicus 54-66 26350338-6 2015 As with 5-HT, activation of GABAA or GABAB receptors, or cannabinoid type 1receptors as well as the tropomyosin-related kinase B receptors by brain-derived neurotrophic factor in the DPAG also inhibits escape expression. dpag 183-187 brain derived neurotrophic factor Homo sapiens 142-175 26350338-8 2015 On the other hand, facilitation of corticotrophin releasing factor- or cholecystokinin-mediated neurotransmission in the DPAG, via CRF1 and CCK2 receptors, respectively, causes panicogenic-like effects with implications for the pathogenesis of PD. dpag 121-125 corticotropin releasing hormone receptor 1 Homo sapiens 131-135 25146701-9 2014 The results indicate that CRF1 receptors in the dPAG play a pervasive role in the regulation of defensive responses associated with both generalized anxiety and panic. dpag 48-52 corticotropin releasing hormone receptor 1 Homo sapiens 26-30 24409327-9 2014 However, the immunohistochemical analysis revealed that LPA 18:1 increased c-Fos expression in the DPAG. dpag 99-103 Fos proto-oncogene, AP-1 transcription factor subunit Rattus norvegicus 75-80 24878577-4 2014 This LPS-induced hyperalgesia was accompanied by distinct recruitment of supra-spinal regions involved in analgesia as indicated by significantly attenuated Fos-protein induction in the rostral dorsal periaqueductal grey (DPAG) as well as rostral and caudal axes of the ventrolateral PAG (VLPAG). dpag 222-226 Fos proto-oncogene, AP-1 transcription factor subunit Rattus norvegicus 157-160 23598399-3 2013 The obtained results showed that intra-dPAG administration of morphine significantly increased escape latency, a panicolytic-like effect that was blocked by pre-treatment with intra-dPAG injection of either naloxone or the 5-HT1A antagonist N-[2-[4-(2-methoxyphenyl)-1 piperazinyl] ethyl] -N- 2- pyridinyl-ciclohexanecarboxamide maleate (WAY-100635). dpag 39-43 5-hydroxytryptamine receptor 1A Rattus norvegicus 223-229 23598399-7 2013 These results suggest a synergic interaction between the 5-HT1A and the micro-opioid receptor at post-synaptic level on neurons of the dPAG that regulate proximal defense, theoretically related to panic attacks. dpag 135-139 5-hydroxytryptamine receptor 1A Rattus norvegicus 57-63 23787365-2 2013 In the dorsal periaqueductal gray matter (dPAG), another key panic-associated area, serotonin, through the activation of 5-HT1A and 5-HT2A receptors, exerts an inhibitory role on escape expression. dpag 42-46 5-hydroxytryptamine receptor 1A Rattus norvegicus 121-133 23787365-8 2013 The results indicate that 5-HT1A and 5-HT2A receptors within the DMH play a phasic inhibitory role upon escape expression, as previously reported in the dPAG. dpag 153-157 5-hydroxytryptamine receptor 1A Rattus norvegicus 26-38 21660445-3 2011 A proposal has been made that 5-HT2A receptor agonists exert their inhibitory effect on escape by activating GABAergic interneurons located in the dPAG. dpag 147-151 5-hydroxytryptamine receptor 2A Rattus norvegicus 30-36 21937980-2 2012 Given the cellular and behavioral evidence suggesting opposite functions for cannabinoid type 1 receptor (CB1) and transient receptor potential vanilloid type-1 channel (TRPV1), we hypothesized that they could differentially influence panic-like reactions induced by electrical stimulation of the dPAG. dpag 297-301 cannabinoid receptor 1 Rattus norvegicus 77-104 21937980-2 2012 Given the cellular and behavioral evidence suggesting opposite functions for cannabinoid type 1 receptor (CB1) and transient receptor potential vanilloid type-1 channel (TRPV1), we hypothesized that they could differentially influence panic-like reactions induced by electrical stimulation of the dPAG. dpag 297-301 cannabinoid receptor 1 Rattus norvegicus 106-109 21937980-2 2012 Given the cellular and behavioral evidence suggesting opposite functions for cannabinoid type 1 receptor (CB1) and transient receptor potential vanilloid type-1 channel (TRPV1), we hypothesized that they could differentially influence panic-like reactions induced by electrical stimulation of the dPAG. dpag 297-301 transient receptor potential cation channel, subfamily V, member 1 Rattus norvegicus 115-168 21937980-2 2012 Given the cellular and behavioral evidence suggesting opposite functions for cannabinoid type 1 receptor (CB1) and transient receptor potential vanilloid type-1 channel (TRPV1), we hypothesized that they could differentially influence panic-like reactions induced by electrical stimulation of the dPAG. dpag 297-301 transient receptor potential cation channel, subfamily V, member 1 Rattus norvegicus 170-175 21937980-9 2012 Supporting this view, we observed that several neurons in the dPAG co-expressed CB1 and TRPV1. dpag 62-66 cannabinoid receptor 1 Rattus norvegicus 80-83 21937980-9 2012 Supporting this view, we observed that several neurons in the dPAG co-expressed CB1 and TRPV1. dpag 62-66 transient receptor potential cation channel, subfamily V, member 1 Rattus norvegicus 88-93 23707246-2 2013 Here, we attempt to show the role played by the TRPV1 receptors within the dorsal periaqueductal gray matter (dPAG), a midbrain structure strongly involved in the modulation of anxiety. dpag 110-114 transient receptor potential cation channel, subfamily V, member 1 Mus musculus 48-53 23007604-5 2013 We also investigated if CBD effects on the ETM depend on facilitation of 5-HT1A-mediated neurotransmission in the DPAG. dpag 114-118 5-hydroxytryptamine receptor 1A Rattus norvegicus 73-79 23007604-6 2013 To this latter aim, we verified if these effects would be prevented by intra-DPAG injection of the 5-HT1A receptor antagonist WAY100635 (0.37 nmol/0.2 muL). dpag 77-81 5-hydroxytryptamine receptor 1A Rattus norvegicus 99-105 23007604-7 2013 Also, we verified, by in vivo microdialysis, if CBD chronic treatment increases serotonin (5-HT) release and, by quantitative polymerase chain reaction, if there are changes in 5HT-1A or 5HT-2C mRNA expression in DPAG. dpag 213-217 5-hydroxytryptamine receptor 1A Rattus norvegicus 177-183 23007604-7 2013 Also, we verified, by in vivo microdialysis, if CBD chronic treatment increases serotonin (5-HT) release and, by quantitative polymerase chain reaction, if there are changes in 5HT-1A or 5HT-2C mRNA expression in DPAG. dpag 213-217 5-hydroxytryptamine receptor 2C Rattus norvegicus 187-193 23007604-10 2013 CBD effects were prevented by DPAG injection of the 5-HT1A receptor antagonist. dpag 30-34 5-hydroxytryptamine receptor 1A Rattus norvegicus 52-58 23007604-11 2013 CONCLUSIONS: Together, these findings suggest that repeated treatment with CBD induces anti-panic effects by acting on 5-HT1A receptors in DPAG. dpag 139-143 5-hydroxytryptamine receptor 1A Rattus norvegicus 119-125 23183042-11 2013 These data refute a cause-and-effect relationship between enhanced dPAG c-fos expression and a reduction in SR. dpag 67-71 Fos proto-oncogene, AP-1 transcription factor subunit Rattus norvegicus 72-77 22450373-8 2012 These results suggest that CRFr1 plays an important role in the defensive behavior and antinociception produced by NO within the dPAG. dpag 129-133 corticotropin releasing hormone receptor 1 Mus musculus 27-32 21660445-8 2011 The inhibitory effect caused by DOI, RO 60-0175, and mCPP was also blocked by previous intra-dPAG injection of the preferential 5-HT2A receptor antagonist ketanserin. dpag 93-97 5-hydroxytryptamine receptor 2A Rattus norvegicus 128-134 21660445-10 2011 CONCLUSIONS: Stimulation of 5-HT2A but not 5-HT2C receptors in the dPAG causes a panicolytic-like effect that is mediated by facilitation of GABAergic neurotransmission. dpag 67-71 5-hydroxytryptamine receptor 2A Rattus norvegicus 28-34 21683728-10 2011 Together, these data suggest differential, state-dependent alterations in electrophysiological activity and ERK phosphorylation along the PFC-amygdala-dPAG pathway during pain, conditioned fear, and FCA. dpag 151-155 Eph receptor B1 Rattus norvegicus 108-111 20570114-10 2011 Although there is a high level of similarity between the behavioral effects obtained in rats (elevated T-maze) and mice (MDTB and RET) with the infusion of 5-HT agonists into the dPAG, the same is not true regarding the effects of blockade of DRN 5-HT(1A) receptors in these rodent species. dpag 179-183 ret proto-oncogene Mus musculus 130-133 21723867-2 2011 In rats, chemical stimulation of dPAG by local infusion of the neuropeptide corticotropin-releasing factor (CRF) provokes anxiogenic effects in the elevated plus-maze test (EPM). dpag 33-37 corticotropin releasing hormone Mus musculus 76-106 21723867-4 2011 Yet, given that there are CRF1 and CRF2 receptor subtypes within the PAG, it is important to show in which receptor subtypes CRF exert its anxiogenic and antinociceptive effects in the dPAG. dpag 185-189 corticotropin releasing hormone receptor 2 Mus musculus 35-48 21421022-3 2011 Since reported evidence has implicated the 5-HT(1A) receptors of the dorsal periaqueductal gray matter (DPAG) in the panicolytic effect of antidepressants, rats treated with pindolol (5.0mg/kg, i.p.) dpag 104-108 5-hydroxytryptamine receptor 1A Homo sapiens 43-50 21421022-7 2011 These results implicate the 5-HT(1A) receptors of the DPAG in the panicolytic effect of the pindolol-paroxetine combination administered systemically. dpag 54-58 5-hydroxytryptamine receptor 1A Homo sapiens 28-35 20561964-10 2010 The results suggest that activation of the DPAG through the GLY(B)/NMDA receptor is able to produce either facilitation or inhibition of nociception depending on the nociceptive context. dpag 43-47 Glycine auxotroph B, complementation of hamster Homo sapiens 60-66 20850460-2 2011 Indirect evidence obtained with non-selective 5-HT2C-interacting drugs suggests that the same may occur in the dPAG, a brainstem region consistently implicated in the genesis/regulation of panic attacks. dpag 111-115 5-hydroxytryptamine receptor 2C Rattus norvegicus 46-52 20850460-9 2011 Overall, the results indicate that 5-HT2C receptors in the dPAG are preferentially involved in the regulation of defensive behaviors related to anxiety, but not panic. dpag 59-63 5-hydroxytryptamine receptor 2C Rattus norvegicus 35-41 20850460-10 2011 This finding extends to the dPAG the prominent role that has been attributed to 5-HT2C receptors in anxiety generation. dpag 28-32 5-hydroxytryptamine receptor 2C Rattus norvegicus 80-86 20457188-2 2010 Cannabidiol (CBD), a major non-psychotomimetic compound present in Cannabis sativa, causes anxiolytic-like effects after intra-dPAG microinjections by activating 5-HT1A receptors. dpag 127-131 5-hydroxytryptamine receptor 1A Rattus norvegicus 162-168 20457188-9 2010 Together, the results suggest that CBD causes panicolytic effects in the dPAG by activating 5-HT1A receptors. dpag 73-77 5-hydroxytryptamine receptor 1A Rattus norvegicus 92-98 20047714-10 2010 Bicuculline also blocked the inhibitory effect of BDNF on mean arterial pressure increase caused by electrical stimulation of DPAG. dpag 126-130 brain-derived neurotrophic factor Rattus norvegicus 50-54 20514481-7 2010 Ultrasound application increased c-Fos expression in the dorsal and dorsolateral PAG (dPAG, dlPAG) and amygdaloid subregions. dpag 86-90 Fos proto-oncogene, AP-1 transcription factor subunit Rattus norvegicus 33-38 20478359-4 2010 The results showed that intra-dPAG injection of WAY-100635 or ketanserin, 5-HT(1A) and 5-HT(2A/2C) receptor antagonists, respectively, counteracted the anti-escape effect caused by bilateral intra-LHb injection of kainic acid (60pmol/0.2microl). dpag 30-34 5-hydroxytryptamine receptor 1A Rattus norvegicus 74-81 20478359-4 2010 The results showed that intra-dPAG injection of WAY-100635 or ketanserin, 5-HT(1A) and 5-HT(2A/2C) receptor antagonists, respectively, counteracted the anti-escape effect caused by bilateral intra-LHb injection of kainic acid (60pmol/0.2microl). dpag 30-34 5-hydroxytryptamine receptor 2A Rattus norvegicus 87-94 20478359-4 2010 The results showed that intra-dPAG injection of WAY-100635 or ketanserin, 5-HT(1A) and 5-HT(2A/2C) receptor antagonists, respectively, counteracted the anti-escape effect caused by bilateral intra-LHb injection of kainic acid (60pmol/0.2microl). dpag 30-34 luteinizing hormone subunit beta Rattus norvegicus 197-200 20478359-6 2010 Overall, the results suggest that the pathway connecting the LHb to the DRN is involved in the control of 5-HT release in the dPAG, and facilitation of 5-HT-mediated neurotransmission in the latter area distinctively impacts upon the expression of anxiety- and fear-related defensive behaviors. dpag 126-130 luteinizing hormone subunit beta Rattus norvegicus 61-64 20528764-6 2010 The reviewed results suggest that chronic, but not acute, administration of antidepressants suppress panic attacks by increasing the release of 5-HT and enhancing the responsivity of post-synaptic 5-HT1A and 5-HT2A receptors in the DPAG. dpag 232-236 5-hydroxytryptamine receptor 1A Homo sapiens 197-209 20528764-6 2010 The reviewed results suggest that chronic, but not acute, administration of antidepressants suppress panic attacks by increasing the release of 5-HT and enhancing the responsivity of post-synaptic 5-HT1A and 5-HT2A receptors in the DPAG. dpag 232-236 5-hydroxytryptamine receptor 2A Homo sapiens 210-214 20047714-4 2010 In this study we investigated the effect of intra-DPAG injection of BDNF in a proposed animal model of panic: the escape response evoked by the electrical stimulation of the same midbrain area. dpag 50-54 brain-derived neurotrophic factor Rattus norvegicus 68-72 20047714-11 2010 Therefore, in the DPAG, BDNF-TrkB signalling interacts with the GABAergic system to cause a panicolytic-like effect. dpag 18-22 brain-derived neurotrophic factor Rattus norvegicus 24-28 20047714-11 2010 Therefore, in the DPAG, BDNF-TrkB signalling interacts with the GABAergic system to cause a panicolytic-like effect. dpag 18-22 neurotrophic receptor tyrosine kinase 2 Rattus norvegicus 29-33 19564136-2 2009 In a previous study, we reported that noradrenaline (NA) microinjection into the dPAG of rats caused pressor response that was mediated by vasopressin release. dpag 81-85 arginine vasopressin Rattus norvegicus 139-150 19631472-12 2010 TRH selective inhibition of DPAG-evoked defensive behaviors adds new evidence that panic attacks may be attenuated by increased levels of this hormone in hypothyroidism. dpag 28-32 thyrotropin releasing hormone Rattus norvegicus 0-3 19564136-11 2009 The results from cobalt treatment indicated that synapses in PVN mediate the vasopressin-induced pressor response caused by NA microinjection into the dPAG. dpag 151-155 arginine vasopressin Rattus norvegicus 77-88 19302815-2 2009 Previously, we reported that noradrenaline (NA) microinjection into the dPAG caused a pressor response that was mediated by vasopressin release into the circulation. dpag 72-76 arginine vasopressin Rattus norvegicus 124-135 18446327-10 2008 CONCLUSIONS: Alprazolam as antidepressants compounds facilitates 5-HT(1A)- and 5-HT(2A)-receptor-mediated neurotransmission in the DPAG, implicating this effect in the mode of action of different classes of antipanic drugs. dpag 131-135 5-hydroxytryptamine receptor 1A Rattus norvegicus 65-72 18076976-4 2008 The 5-HT1A function of the dPAG was evaluated by local injections of 8-OH-DPAT (4 and 8 nmol/0.2 microL) and WAY-100635 (10 nmol/0.2 microL), selective agonist and antagonist of 5-HT1A receptors, respectively. dpag 27-31 5-hydroxytryptamine receptor 1A Rattus norvegicus 4-10 18076976-4 2008 The 5-HT1A function of the dPAG was evaluated by local injections of 8-OH-DPAT (4 and 8 nmol/0.2 microL) and WAY-100635 (10 nmol/0.2 microL), selective agonist and antagonist of 5-HT1A receptors, respectively. dpag 27-31 5-hydroxytryptamine receptor 1A Rattus norvegicus 178-184 18076976-9 2008 Also, the reduction in the regulation of the defensive behaviors by 5-HT1A-mediated mechanisms in the dPAG of these animals may underlie the stress precipitated psychopathology associated with the neural substrates of aversion of the dPAG. dpag 102-106 5-hydroxytryptamine receptor 1A Rattus norvegicus 68-74 18076976-9 2008 Also, the reduction in the regulation of the defensive behaviors by 5-HT1A-mediated mechanisms in the dPAG of these animals may underlie the stress precipitated psychopathology associated with the neural substrates of aversion of the dPAG. dpag 234-238 5-hydroxytryptamine receptor 1A Rattus norvegicus 68-74 17045752-7 2007 injection of the panicogenic cholecystokinin (CCK)(B) receptor agonist pentagastrin (PG, 40 microg kg(-1)) produced an increase in firing rate in 12/17 (70%) of neurons tested in the dPAG. dpag 183-187 cholecystokinin B receptor Rattus norvegicus 29-62 17540371-6 2007 The aim of the present series of experiments was to directly evaluate the role of the CRF1 receptor (CRF1) in dPAG-induced defensive behaviors in the MDTB and the RET paradigms. dpag 110-114 corticotropin releasing hormone receptor 1 Rattus norvegicus 86-90 17540371-6 2007 The aim of the present series of experiments was to directly evaluate the role of the CRF1 receptor (CRF1) in dPAG-induced defensive behaviors in the MDTB and the RET paradigms. dpag 110-114 corticotropin releasing hormone receptor 1 Rattus norvegicus 101-105 17540371-9 2007 Collectively, these results implicate CRF1 in the dPAG as a mediator of temporally and spatially dependent avoidance in response to controllable and constant stimuli. dpag 50-54 corticotropin releasing hormone receptor 1 Rattus norvegicus 38-42 17313964-1 2007 Behavioral evidence indicates that sensitization of 5-HT1A and 5-HT2A receptors in the dorsal periaqueductal gray (DPAG) may underlie the therapeutic effect of serotonin reuptake inhibitors (SRIs) in panic disorder. dpag 115-119 5-hydroxytryptamine receptor 1A Rattus norvegicus 52-64 17313964-3 2007 In this test, chronic administration of the non-selective SRI imipramine enhances the inhibitory effect on escape caused by the intra-DPAG injection of the 5-HT1A receptor agonist 8-OH-DPAT. dpag 134-138 sorcin Rattus norvegicus 58-61 17313964-3 2007 In this test, chronic administration of the non-selective SRI imipramine enhances the inhibitory effect on escape caused by the intra-DPAG injection of the 5-HT1A receptor agonist 8-OH-DPAT. dpag 134-138 5-hydroxytryptamine receptor 1A Rattus norvegicus 156-162 17313964-8 2007 The results indicate that chronic administration of fluoxetine and sertraline sensitizes 5-HT1A receptors in the DPAG. dpag 113-117 5-hydroxytryptamine receptor 1A Rattus norvegicus 89-95 17313964-9 2007 Overall, they support the view that facilitation of 5-HT1A receptor-mediated neurotransmission in the DPAG is implicated in the therapeutic effect of SRIs on panic disorder. dpag 102-106 5-hydroxytryptamine receptor 1A Rattus norvegicus 52-58 17900567-3 2007 The present paper examines the Fos-protein distribution in the brain of rats submitted to a conditioned place aversion (CPA) paradigm using the dPAG chemical stimulation with semicarbazide (SMC), an inhibitor of the GABA synthesizing enzyme, as US and the quadrant of an arena where the drug was injected as the paired neutral stimulus. dpag 144-148 Fos proto-oncogene, AP-1 transcription factor subunit Rattus norvegicus 31-34 17320064-14 2007 These results demonstrate that nNOS within the dPAG plays a differential role in modulating cardiovascular responses and glutamatergic/GABAergic neurotransmission during thermal and mechanical nociception. dpag 47-51 nitric oxide synthase 1 Rattus norvegicus 31-35 15342106-5 2004 We presently evaluate the role of the 5-HT1A, 5-HT2A and 5-HT2C receptors of the DPAG in the modulation of inhibitory avoidance and escape responses of rats submitted to the elevated T-maze. dpag 81-85 5-hydroxytryptamine receptor 1A Rattus norvegicus 38-44 15962186-11 2005 The present findings suggest that the 5-HT2A/2C receptor agonist has an inhibitory effect on maternal aggressive behavior when microinjected into the DPAG and no effect when microinjected into the MS. Ketanserin (1.0 microg/0.2 microl) decreased locomotion when microinjected into the DPAG and MS, but did not affect aggressive behavior. dpag 150-154 5-hydroxytryptamine receptor 2A Rattus norvegicus 38-44 15962186-11 2005 The present findings suggest that the 5-HT2A/2C receptor agonist has an inhibitory effect on maternal aggressive behavior when microinjected into the DPAG and no effect when microinjected into the MS. Ketanserin (1.0 microg/0.2 microl) decreased locomotion when microinjected into the DPAG and MS, but did not affect aggressive behavior. dpag 285-289 5-hydroxytryptamine receptor 2A Rattus norvegicus 38-44 15962186-12 2005 We interpret these findings as evidence for a specific role of 5-HT2A/2C receptors in the DPAG in the inhibition of female aggressive behavior, dissociated from those on motor activity. dpag 90-94 5-hydroxytryptamine receptor 2A Rattus norvegicus 63-69 15165987-6 2004 On the other hand, in nonpretreated rats, the inhibitory effect of dPAG stimulation on the cardiac baroreflex response could be markedly reduced by prior intra-NTS microinjection of granisetron, a 5-HT(3) receptor antagonist, or bicuculline, a GABA(A) receptor antagonist. dpag 67-71 5-hydroxytryptamine receptor 3A Rattus norvegicus 197-213 15265647-11 2004 Thus, the present results support the Fos data and indicate that the DPAG is involved in the expression of some but not all of the cardiovascular and behavioral components of the response to cat odor. dpag 69-73 Fos proto-oncogene, AP-1 transcription factor subunit Rattus norvegicus 38-41 16367785-10 2005 The results suggest that activation of noradrenergic receptors within the dPAG can evoke pressor responses, which are mediated by acute vasopressin release. dpag 74-78 arginine vasopressin Rattus norvegicus 136-147 16231166-4 2005 We also investigated whether the 5-HT(1A) and 5-HT(2A) receptors in the DPAG mediate the behavioral consequences induced by the injection of WAY-100635 into the DRN. dpag 72-76 5-hydroxytryptamine receptor 1A Rattus norvegicus 33-40 16170231-3 2005 In the present study we further explore the hypothesis that sensitization of 5-HT1A and 5-HT 2 A receptors in the DPAG is involved in the anti-panic effect of imipramine. dpag 114-118 5-hydroxytryptamine receptor 1A Rattus norvegicus 77-89 16170231-11 2005 Therefore, chronic imipramine seems to sensitize both 5-HT1A and 5-HT 2 A receptors in the DPAG, strengthening the view that these receptors are involved in the mode of action of anti-panic drugs. dpag 91-95 5-hydroxytryptamine receptor 1A Rattus norvegicus 54-66 15649440-1 2005 Freezing and escape responses induced by gradual increases in the intensity of the electrical current applied to dorsal regions of the periaqueductal gray (dPAG) cause a distinct pattern of Fos distribution in the brain. dpag 156-160 Fos proto-oncogene, AP-1 transcription factor subunit Rattus norvegicus 190-193 15649440-4 2005 To examine further this issue we measured Fos protein expression in brain areas activated by stimulation of the dPAG with glutamate (5 nmol/0.2 microL) and N-methyl-D-aspartate (NMDA) at doses that provoke either freezing (4 nmol/0.2 microL) or escape (7 nmol/0.2 microL) responses, respectively. dpag 112-116 Fos proto-oncogene, AP-1 transcription factor subunit Rattus norvegicus 42-45 15501525-9 2004 The results showed that both the

interpreted as a panicolytic-like effect, is blocked by pretreatment with either the opioid receptor antagonist naloxone or the 5-HT1A receptor (5-HT1A-R) antagonist WAY100635 via injection into the dorsal periaqueductal gray matter (dPAG). dpag 334-338 5-hydroxytryptamine receptor 1A Homo sapiens 228-243 27856260-8 2017 Furthermore, Fos protein-labelled neurons were observed in the dPAG after

responses. dpag 90-94 5-hydroxytryptamine (serotonin) receptor 2C Mus musculus 56-71 26320545-1 2015 Previously reported results have shown that the inhibitory effect of fluoxetine on escape behavior, interpreted as a panicolytic-like effect, is blocked by pretreatment with either the opioid receptor antagonist naloxone or the 5-HT1A receptor (5-HT1A-R) antagonist WAY100635 via injection into the dorsal periaqueductal gray matter (dPAG). dpag 334-338 5-hydroxytryptamine receptor 1A Homo sapiens 245-253 26320545-2 2015 Additionally, reported evidence indicates that the mu-opioid receptor (MOR)

the combined administration of sub-effective doses of the selective MOR agonist DAMGO (intra-dPAG) and sub-effective doses of chronic as well as subchronic (7 days) fluoxetine increased avoidance and escape latencies, suggesting that the activation of MORs may facilitate and accelerate the effects of fluoxetine. dpag 106-110 opioid receptor mu 1 Homo sapiens 81-84 25485771-8 2015 In contrast, treating the dPAG with the kappa-opioid receptor agonist salvinorin-A increased the frequency [F(3,36)=12.4; p<0.01] and duration [F(3,34)=16.1; p<0.01] of defensive immobility induced by GABAA
