Microglia-mediated calcium-permeable AMPAR accumulation in the nucleus accumbens drives hyperlocomotion during cocaine withdrawal. Brain Behav Immun 2024; 115:535-542. [PMID: 37967660 PMCID: PMC10915906 DOI: 10.1016/j.bbi.2023.11.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/27/2023] [Revised: 10/19/2023] [Accepted: 11/11/2023] [Indexed: 11/17/2023] Open
Abstract
During withdrawal from cocaine, calcium permeable-AMPA receptors (CP-AMPAR) progressively accumulate in nucleus accumbens (NAc) synapses, a phenomenon linked to behavioral sensitization and drug-seeking. Recently, it has been suggested that neuroimmune alterations might promote aberrant changes in synaptic plasticity, thus contributing to substance abuse-related behaviors. Here, we investigated the role of microglia in NAc neuroadaptations after withdrawal from cocaine-induced conditioned place preference (CPP). We depleted microglia using PLX5622-supplemented diet during cocaine withdrawal, and after the place preference test, we measured dendritic spine density and the presence of CP-AMPAR in the NAc shell. Microglia depletion prevented cocaine-induced changes in dendritic spines and CP-AMPAR accumulation. Furthermore, microglia depletion prevented conditioned hyperlocomotion without affecting drug-context associative memory. Microglia displayed fewer number of branches, resulting in a reduced arborization area and microglia control domain at late withdrawal. Our results suggest that microglia are necessary for the synaptic adaptations in NAc synapses during cocaine withdrawal and therefore represent a promising therapeutic target for relapse prevention.

Pharmaceuticals (Basel) 2023; 16:ph16010086. [PMID: 36678582 PMCID: PMC9864601 DOI: 10.3390/ph16010086] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2022] [Revised: 01/03/2023] [Accepted: 01/04/2023] [Indexed: 01/11/2023] Open
Abstract
Tramadol and tapentadol, synthetic opioids commonly prescribed for moderate-to-severe pain, have a unique pharmacology that optimizes their analgesia and safety. However, they are not devoid of risks, presenting addictive, abuse, and dependence potential. While tramadol-reinforcing properties have been documented by various studies with human and animal models, including conditioned place preference (CPP) assays, no similar studies have been performed with tapentadol. In the present study, we performed CPP assays by intraperitoneally administering Wistar rats with a tramadol/tapentadol therapeutic dose. Animal permanence and the number of entries in the CPP compartments were recorded in the preconditioning phase and then 1 (T1), 7 (T7), and 14 (T14) days after conditioning. Both opioids induced a change in place preference (T1), suggesting that they have short-term reinforcing properties. However, only tramadol was associated with place preference retention (T7 and T14), with an increase in the number of entries in the opioid-paired compartment (T1 and T7), showing that it causes rewarding memory and incubation of craving. The results indicate that at therapeutic doses: (1) both drugs cause short-term rewarding effects and (2) as opposed to tramadol, tapentadol does not cause CPP retention, despite its higher central nervous system activity and stricter scheduling.

Neural signaling of methamphetamine craving and seeking intensified by bupropion in the ventral tegmental area-cortico-accumbens circuitry in mice. Addict Biol 2022; 27:e13240.

Abstract
Previously, bupropion (BUP), a norepinephrine (NE)/dopamine (DA) transporter blocker and nicotinic acetylcholine receptors (nAChRs) antagonist, was found to intensify methamphetamine (METH) craving behaviours in mice. Intense craving causes relapse in drug dependence. This study characterized local field potential (LFP) patterns in the brain regions associated with METH-conditioned place preference (CPP) enhanced by BUP. Male Swiss albino ICR mice were implanted with LFP electrodes to the ventral tegmental area (VTA), medial prefrontal cortex (mPFC) and the nucleus accumbens core (NAcc). Animals received sessions to learn the association between injection effects (1 mg/kg METH and normal saline) with contextual environments (METH- and saline-paired compartments) during the conditioning phase. A total of 20 mg/kg BUP was given to animals before LFP, and behaviour recording in the CPP apparatus during the post-conditioning phase. The results showed that increased CPP scores and % number of entries to the METH-paired zone, as well as changes in VTA, mPFC and NAcc spectral powers and coherence among these areas, were associated with METH-CPP. Treatment with BUP increased VTA delta and gamma I, decreased mPFC alpha, increased NAcc gamma I and decreased gamma II powers. Coherence analyses revealed that BUP decreased gamma II VTA-mPFC and increased beta and gamma I VTA-NAcc connectivity. Altogether, BUP produced additional effects to that of METH-CPP alone. These findings demonstrated changes in neural circuit activities associated with METH-CPP intensified by BUP. Moreover, modulation of NE/DA systems and/or nAChRs actions in the VTA-cortico-accumbens loop might underlie METH craving and dependence.

Abstract
The conditioned place preference (CPP) procedure has been used to study the incubation of craving phenomenon with rewarding drugs such as cocaine and methamphetamine. The present study examined whether rats trained in a CPP behavioral design would display an incubation of craving response for chocolate-flavored pellets or milk chocolate chips at the behavioral and neural levels. Rats were conditioned using an unbiased CPP design then underwent abstinence from food reward for 24 hs, 7, 14, or 28 days at which point they were tested for CPP. Brains underwent immunohistochemical staining for c-Fos and FosB as well as Golgi staining to assess dendritic spine density in the nucleus accumbens (NAc). A time-dependent increase in CPP and entries into the previously paired compartment was observed in the chocolate-flavored pellet group but not the milk chocolate group. Time-dependent neural changes were not directly associated with behavioral outcomes but c-Fos labelling was higher in the chocolate pellet group than controls at the 7-day abstinence period. The behavioral results show that chocolate pellets are rewarding and are associated with long-term behavioral changes but, as evidenced by limited neural changes, these food rewards do not have the same effects on the NAc as drugs of abuse.

Comparison of the Time-Dependent Changes in Immediate Early Gene Labeling and Spine Density Following Abstinence From Contingent or Non-contingent Chocolate Pellet Delivery. Front Behav Neurosci 2018; 12:144. [PMID: 30061817 PMCID: PMC6055009 DOI: 10.3389/fnbeh.2018.00144] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2018] [Accepted: 06/25/2018] [Indexed: 12/23/2022] Open
Abstract
Rationale: Incubation of craving is a phenomenon whereby responding for cues associated with a reward increases over extended periods of abstinence. Both contingent and non-contingent behavioral designs have been used to study the incubation of craving phenomenon with differing results. The present study directly compares behavioral and neural changes following contingent or non-contingent administration of chocolate flavored pellets. Objective: The current study examined whether an incubation of craving response would be observed at the behavioral and neural levels following delays of abstinence from chocolate pellets in a contingent or non-contingent reinforcement design. Methods: Rats were trained for 10 days to bar press for chocolate pellets (contingent) or received chocolate pellets in a non-contingent design (classical conditioning). Groups were then subjected to abstinence from the reward for 24 h, 7, 14 or 28 days at which point they were tested for responding for reward associated cues. Following the test, brains from all rats were processed and assessed for c-Fos and FosB labeling as well as dendritic spine density in the nucleus accumbens (NAc). Results: Behavioral measures during the test (lever presses, food hopper entries and locomotor activity) revealed similar behavioral outcomes across all delays indicating the lack of an incubation of craving response on both the contingent and non-contingent designs. Overall, labeling of c-Fos in the NAc was lower for the non-contingent group compared to the operant-trained and food restricted control. Compared to the operant-trained and non-trained control groups, a significantly reduced FosB labeling was noted in the NAc of the classically conditioned groups across all abstinence periods. Spine density in the NAc was elevated in both the classically and operant conditioned compared to the food-restricted, non-trained controls. Conclusions: Chocolate pellet reward did not result in incubation of craving but did produce behavioral learning that was associated with increased spine density. This suggests that chocolate pellet administration results in long-term structural and functional changes that are present for at least 28 days following abstinence. Contingent and non-contingent administration resulted in differential immediate early gene labeling in the NAc, but the functional significance of this has yet to be elucidated.

Abstract
The present protocol describes the Conditioned Place Preference (CPP) as a model of relapse in drug addiction. In this model, animals are first trained to acquire a conditioned place preference in a drug-paired compartment, and after the post-conditioning test, they perform several sessions to extinguish the established preference. The CPP permits the evaluation of the conditioned rewarding effects of drugs related to environmental cues. Then, the extinguished CPP can be robustly reinstated by the non-contingent administration of a priming dose of the drug, and by exposure to stressful stimuli. Both methods will be explained here. When the animal reinitiates the behavioral response, a reinstatement of the conditioned reward is considered to have taken place. The main advantages of this protocol are that it is non-invasive, inexpensive, and simple with good validity criteria. In addition, it allows the study of different environmental manipulations, such as stress or diet, which can modulate relapse into drug seeking behaviors. However, one limitation is that if the researcher aims to explore the motivation and primary reinforcing effects of the drug, it should be complemented with self-administration procedures, as they involve operant responses of animals.

Abstract
Orexinergic system is involved in reward processing and drug addiction. Objectives here, we investigated the effect of intra-hippocampal CA1 administration of orexin-1 receptor (OX1r) antagonist on the expression, and extinction of morphine-induced place preference in rats. Conditioned place preference (CPP) was induced by subcutaneous injection of morphine (5 mg/kg) during a 3-day conditioning phase. Two experimental plots were designed; SB334867 as a selective OX1r antagonist was dissolved in 12% DMSO, prepared in solutions with different concentrations (3, 30, and 300 nM), and microinjected into the CA1 and some neighboring regions (0.5 μl/side), bilaterally. CPP score and locomotor activity were recorded during the CPP test. Results demonstrated that intra-CA1 administration of the OX1r antagonist attenuates the expression of morphine-induced CPP. Furthermore, higher concentrations of SB334867 facilitated the extinction period of morphine-induced CPP and reduced its latency. Nevertheless, solely administration of DMSO did not have any influence on the CPP scores and locomotion in both phases. Our findings suggest that OX1rs in the CA1 region of the hippocampus are involved in the expression of morphine CPP. Moreover, blockade of OX1rs could facilitate extinction and may extinguish the ability of drug-related cues. It seems that the antagonist might be considered as a propitious therapeutic agent in suppressing drug-seeking behaviors.
