Front Neuroendocrinol 2023; 69:101060. [PMID: 36758768 DOI: 10.1016/j.yfrne.2023.101060] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/30/2022] [Revised: 01/25/2023] [Accepted: 02/03/2023] [Indexed: 02/09/2023]
Abstract
In this review we systematically summarize the effects of progesterone and synthetic progestins on neurogenesis, synaptogenesis, myelination and six neurotransmitter systems. Several parallels between progesterone and older generation progestin actions emerged, suggesting actions via progesterone receptors. However, existing results suggest a general lack of knowledge regarding the effects of currently used progestins in hormonal contraception regarding these cellular and molecular brain parameters. Human neuroimaging studies were reviewed with a focus on randomized placebo-controlled trials and cross-sectional studies controlling for progestin type. The prefrontal cortex, amygdala, salience network and hippocampus were identified as regions of interest for future preclinical studies. This review proposes a series of experiments to elucidate the cellular and molecular actions of contraceptive progestins in these areas and link these actions to behavioral markers of emotional and cognitive functioning. Emotional effects of contraceptive progestins appear to be related to 1) alterations in the serotonergic system, 2) direct/indirect modulations of inhibitory GABA-ergic signalling via effects on the allopregnanolone content of the brain, which differ between androgenic and anti-androgenic progestins. Cognitive effects of combined oral contraceptives appear to depend on the ethinylestradiol dose.

Abstract
There is currently a lack of understanding of how surgical menopause can influence obsessions, compulsions and associated affective and cognitive functions in female obsessive-compulsive disorder (OCD) patients. Early menopause in women due to surgical removal of ovaries not only causes dramatic hormonal changes, but also may induce affective and cognitive disorders. Here, we tested if surgical removal of ovaries (ovariectomy, OVX), which mimics surgical menopause in humans, would result in exacerbation of compulsive, affective and cognitive behaviors in mice strains that exhibit a spontaneous compulsive-like phenotype. Female mice from compulsive-like BIG, non-compulsive SMALL and randomly-bred Control strains were subjected to OVX or sham-surgery. After 7 days animals were tested for nest building and marble burying to measure compulsive-like behavior. The elevated plus maze and open field tests measured anxiety-like behaviors, while memory was assessed by the novel object recognition. Acute OVX resulted in exacerbation of compulsive-like and anxiety-like behaviors in compulsive-like BIG mice. No significant effects of OVX were observed for the non-compulsive SMALL and Control strains. Object recognition memory was impaired in compulsive-like BIG female mice compared to the Control mice, without an effect of OVX on the BIG mice. We also tested whether 17 β-estradiol (E2) or progesterone (P4) could reverse the effects of OVX. E2, but not P4, attenuated the compulsive-like behaviors in compulsive-like BIG OVX female mice. The actions of the sex steroids on anxiety-like behaviors in OVX females were strain and behavioral test dependent. Altogether, our results indicate that already existing compulsions can be worsened during acute ovarian deprivation concomitant with exacerbation of affective behaviors and responses to hormonal intervention in OVX female mice can be influenced by genetic background.

Postnatal administration of allopregnanolone modifies glutamate release but not BDNF content in striatum samples of rats prenatally exposed to ethanol. BIOMED RESEARCH INTERNATIONAL 2015; 2015:734367.

Abstract
Ethanol consumption during pregnancy may induce profound changes in fetal CNS development. We postulate that some of the effects of ethanol on striatal glutamatergic transmission and neurotrophin expression could be modulated by allopregnanolone, a neurosteroid modulator of GABAA receptor activity. We describe the acute pharmacological effect of allopregnanolone (65 μg/kg, s.c.) administered to juvenile male rats (day 21 of age) on the corticostriatal glutamatergic pathway, in both control and prenatally ethanol-exposed rats (two ip injections of 2.9 g/kg in 24% v/v saline solution on gestational day 8). Prenatal ethanol administration decreased the K+-induced release of glutamate regarding the control group. Interestingly, this effect was reverted by allopregnanolone. Regarding BDNF, allopregnanolone decreases the content of this neurotrophic factor in the striatum of control groups. However, both ethanol alone and ethanol plus allopregnanolone treated animals did not show any change regarding control values. We suggest that prenatal ethanol exposure may produce an alteration of GABAA receptors which blocks the GABA agonist-like effect of allopregnanolone on rapid glutamate release, thus disturbing normal neural transmission. Furthermore, the reciprocal interactions found between GABAergic neurosteroids and BDNF could underlie mechanisms operating during the neuronal plasticity of fetal development.

Abstract
OBJECTIVES Progesterone has been reported to have a neuroprotective role in depression-like rats in a hemiparkinsonian model of the disease. In this work, we investigate if this hormone affects the three principal neurochemicals striatal systems (dopaminergic, glutamatergic, and GABAergic) that are involved in the physiopathology of the disease in a hemiparkinsonim male rat model at 8 weeks post-chemical injury. METHODS For this purpose, we design three experimental groups: (1) sham group; (2) hemiparkinsonian group; and (3) hemiparkinsonian group subcutaneously injected with progesterone at 7 days post-chemical injury. Animals were tested in an automated rotational device at 8 weeks post-chemical injury. After behavioral test, K(+)-evoked [(3)H]-dopamine, [(3)H]-glutamate, and [(3)H]-gamma aminobutyric acid release from striatum slices were analyzed by superfusion experiments. RESULTS The hemiparkinsonian group showed distinctive alterations that are produced by neurodegeneration of left nigrostriatal dopaminergic pathway by 6-hydroxydopamine hydrobromide (6-OHDA). On the other hand, the administration of progesterone 7 days after the injection of the neurotoxin was able to (1) improve the K(+)-evoked [(3)H]-dopamine release from the damaged striata (left); (2) avoid significant increase in the K(+)-evoked [(3)H]-glutamate release from the left striata; and (3) progesterone does not modify the K(+)-evoked [(3)H]-gamma aminobutyric acid release from the left striata. DISCUSSION These results suggest that progesterone does have neuroprotective and neuromodulatory effects on striatal neurotransmission systems in the hemiparkinsonian male rats. The possible mechanisms would involve genomic and non-genomic actions of this neuroactive steroid which would modulate the activity of dopaminergic, glutamatergic, and GABAergic pathways.

Abstract
1. The neurosteroids are compounds derived from steroid hormones and synthesized in the nervous system. They can modulate different neurotransmitter pathways. In previous work we demonstrated that progesterone modulates dopamine release induced by the glutamatergic agonist N-methyl-D-aspartic acid (NMDA). 2. The aim of this work was to evaluate a possible modulatory role of the progesterone metabolite allopregnanolone on NMDA-evoked [3H]dopamine release from corpus striatum slices obtained from cycling and ovariectomized female rats. 3. We used a dynamic superfusion method to evaluate the release of [3H]dopamine. Allopregnanolone at 50-600 nM was added to the superfusion buffer (Krebs-Ringer-bicarbonate-glucose. pH 7.4. with constant O2/CO2 gassing). The results are expressed as a percentage over basal [3H]dopamine loaded by the tissue. 4. Allopregnanolone (50 and 100 nM) increased the NMDA-evoked [3H]dopamine release from estrus rats. The remaining doses did not show significant changes in the pattern of release. This effect was not observed in diestrus rats. The ovariectomy abolished the facilitatory effect of allopregnanolone on NMDA-evoked 2 [3H]dopamine release. 5. Subcutaneous administration of exogenous estrogen (25 mg/rat) and progesterone (1 mg/rat) restored the facilitatory effect on dopaminergic input. 6. These results suggest that allopregnanolone is a neurosteroid able to modulate dopamine release in an ovarian-hormone-fluctuation-dependent manner and provide further support for a role of allopregnanolone as a modulator of glutamatergic-dopaminergic interaction in the corpus striatum.

Abstract
The IPL nude rat, derived by spontaneous mutation from the Sprague-Dawley strain, presents alterations in the prolactin synthesis and secretion due to an increased dopaminergic inhibition. However, there are no reports concerned to central dopamine activity. The corpus striatum is a brain area involved in the development of stereotyped behavior after the activation of mesolimbic and/or nigro-striatal dopamine pathways. In order to identify possible mesolimbic and/or nigro-striatal dysfunctions in the IPL nude rat, we study the spontaneous oral behaviors and the effects of apomorphine-induced dopaminergic activation on stereotyped behavior and neurochemical changes. Males from both strains were injected with saline or apomorphine (2 and 5 mg/kgs.c.) and evaluated during 30 min in a stereotypes oral tests. The corpus striatum and nucleus accumbens were used to measure dopamine (DA), 3,4-dihydroxyphenylalanine (DOPA) and 3,4-dihydroxyphenylacetic acid (DOPAC) by HPLC. The concentrations were expressed as synthesis rate (DA/DOPA) and turnover rate (DOPAC/DA). We observed that the spontaneous gnaw movements were significantly different between the untreated IPL nude and Sprague-Dawley (SD) rats. Apomophine injection decreased the amount of stereotyped gnawing in IPL nude rats at the two doses used, but it induced an increase in SD rats. Apomorphine also caused an enhancement in the number of biting and sniffing without modifying the licking behavior. In addition, modifications of the dopaminergic activity were also observed. Synthesis rate in the striatum of IPL nude rats was higher than in SD rats after the injection of saline. Apomorphine caused a reduction of the synthesis rate in both strains. Turnover rate was significantly lower in the striatum of IPL nude rats than in the SD rats injected with saline. Apomorphine caused an increase in the turnover rate in both strains. Contrary to observed in the striatum, the 2 mg/kg dose of apomorphine caused a significant increase in the DA synthesis rate in nucleus accumbens, while 5 mg/kg decrease it in both strains. The DA turnover rate in the same area was lower in IPL nude than in SD rats after saline injection. Apomorphine enhances the DA turnover rate in both strains. We conclude that the modifications of the oral spontaneous and induced stereotypical patterns observed in the IPL nude rats could be related to the differential responses in dopaminergic activity in the two brain areas examined.

Abstract
Ischemia-induced hyperactivity is recognized several hours after both common carotid arteries' occlusion for 5 min in Mongolian gerbils, and it continues for at least 7 days. The aim of this study is to investigate the possible mechanisms of this abnormal behavior. Methamphetamine (MAP) (1 and 3 mg /kg) was administered for 7 days and imipramine (IMP) (5 and 10 mg/kg) was administered for 7 or 14 days. Bilateral carotid artery was occluded for 5 min 24 h after the last administrations of these drugs. MAP, which had been administered every day for 1 week, showed marked inhibition in the ischemia-induced hyperactivity. However, IMP did not have any effect even though it had been injected every day for 2 weeks. Hippocampal CA1 neuronal changes also appeared in the MAP- and IMP-administered groups. As the dopaminergic neurotransmission is facilitated by the repeated administration of MAP, the ischemia-induced hyperactivity may be related to abnormalities in dopaminergic function. The participation of the other neurotransmitters is also discussed.

Abstract
The behavioural display in the plus-maze, an established experimental model of anxiety, was studied in rats injected into the lateral brain ventricle (i.c.v.) with the neurosteroid 3 alpha-hydroxy-5 alpha-pregnan-20-one (allopregnanolone). Female rats under different gonadal hormonal status were chosen. Allopregnanolone enhanced exploration of the open arms in both estrous rats and ovariectomized estrogen and progesterone primed rats. No effect was observed in diestrous 1 and ovariectomized not-primed rats. In all cases, the plus-maze locomotor-exploratory behaviour was not affected by allopregnanolone. The GABA(A) receptor antagonist, bicuculline (9.8 microM i.c.v.) reversed the allopregnanolone action in the ovariectomized primed rats. When bicuculline was injected i.c.v. in conjunction with allopregnanolone, the anxiogenic effect of bicuculline was reversed by the highest dose (25 microM) of allopregnanolone only. These results suggest that allopregnanolone exerts an anxiolytic action interacting with the GABA(A) receptor in an estrogen-dependent manner.

Abstract
The effects of the competitive NMDA receptor antagonist CPP on the initiation of behavioral sensitization to acute cocaine and basal and acute cocaine-induced dopamine (DA) release in the nucleus accumbens (NAC) were assessed in female Sprague-Dawley rats. Cocaine pretreated rats (30 mg/kg IP, once daily for 7 days) challenged with cocaine (10 mg/kg) on day 8 displayed increased motor activity relative to controls challenged with cocaine on day 8. This effect was blocked in rats receiving CPP (2 mg/kg) 15 min prior to all cocaine pretreatments. Basal DA levels in the NAC of both cocaine-pretreated and CPP plus cocaine-pretreated rats were higher on day 8 compared to controls. Acute cocaine challenge on day 8 resulted in increased extracellular DA concentrations in the NAC in control rats, no increase in rats pretreated with CPP plus cocaine, and a decrease in rats pretreated with cocaine only. These data demonstrate that development of behavioral sensitization to cocaine in female Sprague-Dawley rats can be completely blocked by a peripherally administered competitive NMDA receptor antagonist and that an increase in DA release in the NAC after a cocaine challenge is not an absolute requirement for expression of motor sensitization to cocaine in female rats.
