Functional and phosphoproteomic analysis of β-adrenergic receptor signaling at excitatory synapses in the CA1 region of the ventral hippocampus. Sci Rep 2023; 13:7493. [PMID: 37161045 PMCID: PMC10170123 DOI: 10.1038/s41598-023-34401-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2022] [Accepted: 04/28/2023] [Indexed: 05/11/2023] Open
Abstract
Activation of β-adrenergic receptors (β-ARs) not only enhances learning and memory but also facilitates the induction of long-term potentiation (LTP), a form of synaptic plasticity involved in memory formation. To identify the mechanisms underlying β-AR-dependent forms of LTP we examined the effects of the β-AR agonist isoproterenol on LTP induction at excitatory synapses onto CA1 pyramidal cells in the ventral hippocampus. LTP induction at these synapses is inhibited by activation of SK-type K+ channels, suggesting that β-AR activation might facilitate LTP induction by inhibiting SK channels. However, although the SK channel blocker apamin enhanced LTP induction, it did not fully mimic the effects of isoproterenol. We therefore searched for potential alternative mechanisms using liquid chromatography-tandem mass spectrometry to determine how β-AR activation regulates phosphorylation of postsynaptic density (PSD) proteins. Strikingly, β-AR activation regulated hundreds of phosphorylation sites in PSD proteins that have diverse roles in dendritic spine structure and function. Moreover, within the core scaffold machinery of the PSD, β-AR activation increased phosphorylation at several sites previously shown to be phosphorylated after LTP induction. Together, our results suggest that β-AR activation recruits a diverse set of signaling pathways that likely act in a concerted fashion to regulate LTP induction.

[PMID: 32165259 DOI: 10.1016/j.neulet.2020.134892] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2020] [Revised: 02/12/2020] [Accepted: 03/04/2020] [Indexed: 12/16/2022]
Abstract
Benzodiazepines and SSRIs are considered as standard treatment options for anxiety and depression, hallmarks of Post-Traumatic Stress Disorder (PTSD), although their use is often limited by adverse effects. While promising evidence emerged with β-adrenergic receptor (β-AR) antagonists (or 'β-blockers') and PTSD relief, efficacy issues dampened the excitement. However, we believe it is premature to completely eliminate a beneficial role of β-blockers. Our previous work has suggested that social defeat (SD) results in anxiety-like and depression-like behaviors in rats. Here, using the SD paradigm, we examined the effect of several β-adrenergic receptor antagonists (propranolol, nadolol, bisoprolol) on these behaviors in rats. Following acclimatization, Sprague-Dawley rats received no treatment (for control groups) or treated with ; propranolol (50 mg/kg/day in water), or nadolol (18 mg/kg/day in rats' chow), or bisoprolol (15 mg/kg/day in water). The treatment lasted for 36 days, following which rats were subjected to SD/control exposures (1 week). Later, anxiety-like and depression-like behaviors, social interaction and learning-memory function tests were conducted. SD rats exhibited anxiety- and depression-like behavior as well as learning-memory impairment. Propranolol and nadolol protected SD rats from exhibiting anxiety-or depression-like behaviors. Bisoprolol treatment did not mitigate SD-induced behavioral impairments in rats. Nadolol, propranolol or bisoprolol have no effect in attenuating SD-induced memory function tests. These results suggest that certain 'β-blockers' have the potential to mitigate the negative psychological effects of traumatic events.

Abstract
A roadblock to successful treatment for anxiety and depression is the high proportion of individuals that do not respond to existing treatments. Different underlying neurobiological mechanisms may drive similar symptoms, so a more personalized approach to treatment could be more successful. There is increasing evidence that sex is an important biological variable modulating efficacy of antidepressants and anxiolytics. We review evidence for sex-specific effects of traditional monoamine based antidepressants and newer pharmaceuticals targeting kappa opioid receptors (KOR), oxytocin receptors (OTR), and N-methyl-D-aspartate receptors (ketamine). In some cases, similar behavioral effects are observed in both sexes while in other cases strong sex-specific effects are observed. Most intriguing are cases such as ketamine which has similar behavioral effects in males and females, perhaps through sex-specific neurobiological mechanisms. These results show how essential it is to include both males and females in both clinical and preclinical evaluations of novel antidepressants and anxiolytics.

Abstract
Male parental care is an important social behavior for several mammalian species. Psychosocial stress is usually found to inhibit maternal behavior, but effects on paternal behavior have been less consistent. We tested the effects of social defeat stress on pair bond formation and paternal behavior in the monogamous California mouse (Peromyscus californicus). Social defeat reduced time spent in a chamber with a stranger female during a partner preference test conducted 24h after pairing, but increased latency to the first litter. In 10min partner preference tests conducted after the birth of pups, both control and stressed males exhibited selective aggression towards stranger females. Unlike prairie voles, side by side contact was not observed in either partner preference test. Stressed male California mice engaged in more paternal behavior than controls and had reduced anxiety-like responses in the open-field test. Defeat stress enhanced prodynorphin and KOR expression in the medial preoptic area (MPOA) but not PVN. Increased KOR signaling has been linked to increased selective aggression in prairie voles. Together the results show that defeat stress enhances behaviors related to parental care and pair bonding in male California mice.

Abstract
Social stress has deteriorating effects on various psychiatric diseases. In animal models, exposure to socially dominant conspecifics (i.e., social defeat stress) evokes a species-specific defeat posture via unknown mechanisms. Oxytocin neurons have been shown to be activated by stressful stimuli and to have prosocial and anxiolytic actions. The roles of oxytocin during social defeat stress remain unclear. Expression of c-Fos, a marker of neuronal activation, in oxytocin neurons and in oxytocin receptor‒expressing neurons was investigated in mice. The projection of oxytocin neurons was examined with an anterograde viral tracer, which induces selective expression of membrane-targeted palmitoylated green fluorescent protein in oxytocin neurons. Defensive behaviors during double exposure to social defeat stress in oxytocin receptor‒deficient mice were analyzed. After social defeat stress, expression of c-Fos protein was increased in oxytocin neurons of the bed nucleus of the stria terminalis, supraoptic nucleus, and paraventricular hypothalamic nucleus. Expression of c-Fos protein was also increased in oxytocin receptor‒expressing neurons of brain regions, including the ventrolateral part of the ventromedial hypothalamus and ventrolateral periaqueductal gray. Projecting fibers from paraventricular hypothalamic oxytocin neurons were found in the ventrolateral part of the ventromedial hypothalamus and in the ventrolateral periaqueductal gray. Oxytocin receptor‒deficient mice showed reduced defeat posture during the second social defeat stress. These findings suggest that social defeat stress activates oxytocin-oxytocin receptor systems, and the findings are consistent with the view that activation of the oxytocin receptor in brain regions, including the ventrolateral part of the ventromedial hypothalamus and the ventrolateral periaqueductal gray, facilitates social defeat posture.

Abstract
INTRODUCTION Integrity of the great saphenous vein (GSV) endothelium is the most important key element for long-term patency rate of grafts in coronary artery bypass graft (CABG). Storage solutions play an important role in maintaining viability of vein endothelium. Diminished nitric oxide (NO) because of endothelial dysfunction may facilitate vascular inflammation and formation of atherosclerotic plaque. AIM So, we decided to find a reasonable alternative preservative solution instead of heparinized blood (HB) by measuring NO concentration with Griess assay. MATERIAL AND METHOD SVG samples were obtained from 54 patients undergoing elective CABG. 3 mm rings were stored in solutions: heparinized blood (HB), Krebs (K), Krebs + Propranolol (K+P) 6.66 g/l, Krebs + Adrenaline (K+A) 200 µl/l, and Krebs + Verapamil (K+V) 200 µl/l for 30, 45, 60 and 90 min. Nitrite concentration was measured by Griess assay at 540 nm. H&E staining was performed for histologic test. Statistical analysis was performed using SPSS (V16). Results were expressed as (Means ± SE) followed by One-Way ANOVA for finding best preservative solution. Repeated measurement test was used to investigate best time. In all analysis, (P<0.05) was considered significant. RESULTS Average concentration of NO in (K+V) compare with HB (1st control), K (2nd control), (K+A) and (K+P) showed higher rate in all times from 30 to 90 min (16.55±1.85:) and in (K+A, K+P) compare with (HB) and (K) there was no statistically significant difference in the same times. Comparing the average concentration of (NO) between (HB) and (K) showed no significant difference (K+V>HB=K=K+A=K+P). Also, our investigations showed that NO concentration in (K+V) has the highest rate in time 90 min (10.07±0.56, p=0.002):. More than 50 percent of endothelial cells stay normal in (K+V) compare with other solutions. CONCLUSION It seems that (K+V) is the best solution for the maintenance of normal physiology of SVGs endothelial cells. The most appropriate SVGs endothelial function is within 90 minutes after harvesting.

Inhibition of vasopressin V1a receptors in the medioventral bed nucleus of the stria terminalis has sex- and context-specific anxiogenic effects. Neuropharmacology 2016; 110:59-68.

Abstract
Vasopressin V1a receptors (V1aR) are thought to contribute to the pathophysiology of psychiatric disorders such as anxiety and depression, sparking interest in V1aR as a therapeutic target. Although the global effects of V1aR have been documented, less is known about the specific neural circuits mediating these effects. Moreover, few studies have examined context-specific V1aR function in both males and females. By using the California mouse, we first studied the effects of sex and social defeat stress on V1aR binding in the forebrain. In females but not males, V1aR binding in the bed nucleus of the stria terminalis (BNST) was negatively correlated to social interaction behavior. In females stress also increased V1aR binding in the nucleus accumbens (NAc). Infusions of V1aR antagonist in to the medioventral BNST (BNSTmv) had anxiogenic effects only in animals naïve to defeat. For males, inhibition of V1aR in BNSTmv had anxiogenic effects in social and nonsocial contexts, but for females, anxiogenic effects were limited to social contexts. In stressed females, inhibition of V1aR in the NAc shell had no effect on social interaction behavior, but had an anxiogenic effect in an open field test. These data suggest that V1aR in BNSTmv have anxiolytic and prosocial effects in males, and that in females, prosocial and anxiolytic effects of V1aR appear to be mediated independently by receptors in the BNSTmv and NAc shell, respectively. These findings suggest that males have more overlap in neural circuits modulating anxiety in social and nonsocial contexts than females.
