Abstract
The quality of social relationships is a powerful determinant of lifetime health. Here, we explored the impact of social experiences on circulating oxytocin (OT) concentration, telomere length (TL), and novelty-seeking behaviour in male and female rats. Prolonged social housing raised circulating OT levels in both sexes while elongating TL only in females. Novelty-seeking behaviour in females was more responsive to social housing and increased OT levels than males. The OT antagonist (OT ANT) L-366,509 blocked the benefits of social housing in all conditions along with female-specific TL erosion and novelty-seeking deficit. Thus, females seem more susceptible than males to genetic and behavioural changes when the secretion of endogenous OT in response to social life is interrupted. Social enrichment may, therefore, provide a therapeutic avenue to promote stress resiliency and chances of healthy aging across generations.

Abstract
Ibogaine is a plant-derived alkaloid and dissociative psychedelic that demonstrates anti-addictive properties with several substances of abuse, including alcohol. 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT) is a naturally occurring psychedelic known to occasion potent mystical-type experiences and also demonstrates anti-addictive properties. The potential therapeutic effects of both compounds in treating alcohol use disorder require further investigation and there are no published human neuroimaging findings of either treatment to date. We present the case of a 31-year-old male military veteran with moderate alcohol use disorder who sought treatment at an inpatient clinic in Mexico that utilized a sequential protocol with ibogaine hydrochloride (1550mg, 17.9mg/kg) on day 1, followed by vaporized 5-MeO-DMT (bufotoxin source 50mg, estimated 5-MeO-DMT content, 5-7mg) on day 3. The patient received SPECT neuroimaging that included a resting-state protocol before, and 3 days after completion of the program. During the patient's ibogaine treatment, he experienced dream-like visions that included content pertaining to his alcohol use and resolution of past developmental traumas. He described his treatment with 5-MeO-DMT as a peak transformational and spiritual breakthrough. On post-treatment SPECT neuroimaging, increases in brain perfusion were noted in bilateral caudate nuclei, left putamen, right insula, as well as temporal, occipital, and cerebellar regions compared to the patient's baseline scan. The patient reported improvement in mood, cessation of alcohol use, and reduced cravings at 5 days post-treatment, effects which were sustained at 1 month, with a partial return to mild alcohol use at 2 months. In this case, serial administration of ibogaine and 5-MeO-DMT resulted in increased perfusion in multiple brain regions broadly associated with alcohol use disorders and known pharmacology of both compounds, which coincided with a short-term therapeutic outcome. We present theoretical considerations regarding the potential of both psychedelic medicines in treating alcohol use disorders in the context of these isolated findings, and areas for future investigation.

Abstract
RATIONALE Neuropeptides are linked to the psychopathology of stimulants of abuse, principally through dopamine mechanisms. Substance P (SP) is one of these neuropeptides and is associated with both limbic and extrapyramidal dopaminergic pathways and likely contributes to the pharmacology of these stimulants. The effects of nicotine on these dopamine systems have also been extensively studied; however, its effects on the associated SP pathways have received little attention. OBJECTIVES In the present study, we elucidated the effects of nicotine treatment on limbic and extrapyramidal SP systems by measuring changes in associated SP tissue concentrations. MATERIALS AND METHODS Male Sprague-Dawley rats received (+/-)nicotine 4.0 mg/kg/day (0.8 mg/kg, intraperitoneally; five injections at 2-h intervals) in the presence or absence of selective dopamine D1 and D2 receptor antagonists or a nonselective nicotinic acetylcholine receptor antagonist. RESULTS The nicotine treatment significantly but temporarily decreased substance P-like immunoreactivity (SPLI) content in the ventral tegmental area (VTA) and substantia nigra 12-18 h after drug exposure. The nicotine-mediated changes in SPLI were selectively blocked by pretreatment with mecamylamine as well as a dopamine D1, D2, or both receptor antagonists. Other brain areas that also selectively demonstrated nicotine-related declines in SPLI content included prefrontal cortex, the nucleus accumbens shell, and the very posterior caudate. CONCLUSIONS These findings indicate that some limbic and basal ganglia SP systems are significantly affected by exposure to nicotine through processes mediated by nicotinic and dopaminergic receptors, suggesting a role for SP pathways in nicotine's limbic and extrapyramidal effects.

Abstract
Neurokinin3 (NK3) receptors and their endogenous ligands (e.g. the neuropeptide substance P and its C-terminal fragment) have been implicated in psychomotor activity and reinforcement mechanisms. We review here recent findings on the involvement of NK3 receptors in the behavioral and neurochemical effects of cocaine. Although NK3 receptors can modulate dopamine (DA) activity in the brain, recent results suggest that this modulation does not occur during spontaneous behavioral activity. However, NK3 receptors play a role in the regulation of cocaine-induced DA responses in the nucleus accumbens core and shell subregions. NK3 receptor agonism as well as antagonism potentiate cocaine's effects on nucleus accumbens DA subregions specifically, and modulate the acute behavioral effects of cocaine in rats and non-human primates (Callithrix penicillata). However, conditioned place preference studies in rats have, so far, failed to provide evidence for an involvement of NK3 receptors in the reinforcing effects of cocaine.

Abstract
Interest in development of therapeutics targeting brain neuropeptide systems for treatment of cocaine addiction (e.g., kappa opioid agonists) is based on animal data showing interactions between the neuropeptides, brain dopamine, and cocaine. In this autopsied brain study, our major objective was to establish by radioimmunoassay whether levels of dynorphin and other neuropeptides (e.g., metenkephalin, neurotensin and substance P) are increased in the dopamine-rich caudate, putamen, and nucleus accumbens of human chronic cocaine users (n=12) vs. matched control subjects (n=17) as predicted by animal findings. Changes were limited to markedly increased dynorphin immunoreactivity in caudate (+92%), decreased caudate neurotensin (-49%), and a trend for increased dynorphin (+75%) in putamen. In other examined subcortical/cerebral cortical areas dynorphin levels were normal with the striking exception of the ventral pallidum (+346%), whereas cerebral cortical metenkephalin levels were generally decreased and neurotensin variably changed. Our finding that, in contradistinction to animal data, the other striatal neuropeptides were not increased in human cocaine users could be explained by differences in pattern and contingency between human drug users and the animal models. However, the human dynorphin observations parallel well animal findings and suggest that the dynorphin system is upregulated, manifested as elevated neuropeptide levels, after chronic drug exposure in striatum and ventral pallidum. Our postmortem brain data suggest involvement of striatal dynorphin systems in human cocaine users and should add to the interest in the testing of new dynorphin-related therapeutics for the treatment of cocaine addiction.

Abstract
We recently developed a quantitative peptidomics method using stable isotopic labels and mass spectrometry to both quantify and identify a large number of peptides. To test this approach and screen for peptides regulated by cocaine administration, 32 Cpefat/fat mice and 16 wild-type mice were treated twice daily for 5 d either with saline or 10 mg/kg cocaine. Peptides were extracted from striatum, hypothalamus, hippocampus, and prefrontal cortex, and extracts from groups of eight mice were labeled with the N-hydroxysuccinimide ester of trimethylammonium butyrate containing either nine deuterium or nine hydrogen atoms. Pools of heavy- and light-labeled peptides were combined, purified on an anhydrotrypsin affinity column, and analyzed on a reversephase column coupled to an electrospray ionization quadrapole time-of-flight mass spectrometer. Changes in peptide levels upon cocaine treatment were determined from the relative peak intensities of the cocaine versus saline peaks, and peptides were identified from collision-induced dissociation spectra. Ten peptides were found to increase or decrease in each of two separate analyses from distinct groups of mice. Peptides found to increase corresponded to fragments of proenkephalin, prothyrotropin-releasing hormone, provasopressin, proSAAS, secretogranin II, chromogranin B, and peptidyl-glycine-alpha-amidating mono-oxygenase in the hypothalamus. The same peptidyl-glycine-alpha-amidating mono-oxygenase peptide decreased in the prefrontal cortex, along with striatal neurokinin B and two unidentified peptides. Thirty other peptides were not substantially affected by cocaine treatment in both replicates. Taken together, the quantitative peptidomics approach provides an efficient method to screen for changes in a large number of peptides.

Abstract
Brain neuropeptide transmitters of the tachykinin family are involved in the organization of many behaviors. However, little is known about their contribution to the behavioral effects of drugs of abuse. Recently, antagonism of the tachykinin NK3-receptor (NK3-R), one of the three tachykinin receptors in the brain, was shown to attenuate the acute and chronic behavioral effects of cocaine in rats and the acute effects in non-human primates. In order to expand these findings we investigated the effects of the NK3-R agonist, succinyl-[Asp6, Me-Phe8]SP(6-11) (senktide), on the acute behavioral effects of cocaine in marmoset monkeys (Callithrix penicillata) using a figure-eight maze procedure. Animals were pretreated with senktide (0, 0.1, 0.2, 0.4 mg/kg, s.c.), and received either a treatment with cocaine (10 mg/kg) or saline (i.p.). Cocaine increased locomotor activity and the duration of aerial scanning behavior, but reduced exploratory activity, bodycare activity, the frequency of aerial scanning, and terrestrial glance behavior. Senktide blocked the effects of cocaine on locomotor activity, but enhanced the cocaine effects on exploratory activity, aerial scanning frequency, and terrestrial glance behavior. Senktide alone did not significantly influence monkey behavior in this study. These data expand previous findings suggesting a complex role of the NK3-R in the acute behavioral effects of cocaine in non-human primates.

Abstract
Dopamine-induced changes in striatal gene expression are thought to play an important role in drug addiction and compulsive behaviour. In this study we report that dopamine induces the expression of the transcription factor CCAAT/Enhancer Binding Protein beta (C/EBP)-beta in primary cultures of striatal neurones. We identified the preprotachykinin-A (PPT-A) gene coding for substance P and neurokinin-A as a potential target gene of C/EBPbeta. We demonstrated that C/EBPbeta physically interacts with an element of the PPT-A promoter, thereby facilitating substance P precursor gene transcription. The regulation of PPT-A gene by C/EBPbeta could subserve many important physiological processes involving substance P, such as nociception, neurogenic inflammation and addiction. Given that substance P is known to increase dopamine signalling in the striatum and, in turn, dopamine increases substance P expression in medium spiny neurones, our results implicate C/EBPbeta in a positive feedback loop, changes of which might contribute to the development of drug addiction.

Abstract
We tested the tachykinin NK(1) receptor antagonist WIN51708 (17betahydroxy17alphaethynyl5alphaandrostanol[3,2b]pyrimido[1,2-a]benzimidazole) in a behavioral sensitization model. Rats were given 7 days of cocaine then 7 days of withdrawal to induce sensitization. Thereafter, another 7 days of cocaine with WIN51708 (2 mg/kg i.p.) given 3.5 h after each cocaine injection was given. WIN51708 reversed sensitization but had no effect on controls. NK(1) receptor antagonists may have use in stimulant abuse and schizophrenia treatment.

Abstract
There is evidence that the central oxytocin system is activated and undergoes reorganization before parturition. The present study was designed to determine the effects of central oxytocin receptor blockade during late gestation on parturition, pup growth, and oxytocin release during suckling. Female Sprague-Dawley rats were implanted on gestation day 12-14 with Alzet osmotic minipumps containing an oxytocin receptor antagonist (d(CH2)5, Tyr(Me)(2), Orn(8)-vasotocin; OT-X) or artificial cerebrospinal fluid (VEH), which was infused into the third cerebral ventricle. Pumps were removed within 24 h of parturition. Daily maternal body weight and food intake were monitored during gestation and lactation. The length of gestation, duration of parturition, pup number, litter weight and interbirth interval were recorded. Subsequently, pup number and litter weights were recorded daily until lactation day 10 or 11, when maternal and pup behaviour, and plasma oxytocin concentration before and during suckling were measured. Central oxytocin blockade had no effect on the timing of parturition, maternal behaviour, litter size, still births, or litter weights at birth. However, beginning on day 3 of lactation, average weights of litters of OT-X females were significantly lower than litters of VEH-treated females. Furthermore, while basal plasma oxytocin concentrations, oxytocin increases in response to suckling and dam/pup interactions did not differ between groups, a significant delay in suckling-induced systemic oxytocin release was observed in OT-X females. Finally, OT-X dams weighed less than VEH dams during the postpartum observation period, although food intakes were similar. These data suggest that central actions of oxytocin during late gestation are necessary for the normal timing of systemic release of oxytocin during suckling, normal pup weight gain, and maintenance of maternal body weight.

Abstract
Recent studies demonstrated that vesicular dopamine (DA) uptake can be rapidly altered in synaptic vesicles purified from the striata of stimulant-treated rats. Specifically, a single administration of the plasmalemmal DA transporter inhibitor, cocaine, or the DA D(2) agonist, quinpirole, increases vesicular DA uptake in vesicles purified from the striata of treated rats. These effects of cocaine are prevented by pretreatment with a D(2), but not D(1), DA receptor antagonist. The purpose of the present study was to characterize the effect of a mechanistically different psychostimulant, methamphetamine (METH), on vesicular DA uptake. Results demonstrated that a single administration of this DA-releasing agent rapidly and reversibly decreased vesicular DA uptake. The METH-related decrease in vesicular DA uptake was attenuated by pretreatment with the D(2) antagonist, eticlopride, but not the D(1) antagonist, SCH23390 (R-[+]-7-chloro-8-hydroxy-3-methyl-1-phenyl-2,3,4,5-tetrahydro-1H-3-benzazepine). Core body temperature did not contribute to the effects of METH on vesicular DA uptake. Neither quinpirole nor cocaine increased vesicular DA uptake when rats were concurrently treated with METH. These studies provide further evidence that psychostimulants rapidly and differentially modify vesicular DA uptake. In addition, these studies demonstrate a complex role for D(2) DA receptors in altering vesicular DA transport.
