Previous studies demonstrated both sex differences and an effect of estrous cycle in female rats in incubation of cocaine craving. In contrast, while incubation of methamphetamine craving is similar across sexes, whether estrous cycle plays a role in this incubation has yet to be fully addressed. Moreover, whether neural mechanisms underlying incubation of methamphetamine craving differ across estrous cycles is largely unknown. To address these gaps, we first compared methamphetamine self-administration, and methamphetamine seeking on both abstinence days 1 and 28 between male rats and female rats across the estrous cycle. Next, we examined neuronal activation associated with incubated methamphetamine seeking in dorsomedial striatum (DMS) and lateral portion of the anterior intralaminar nucleus of thalamus (AIT-L), two brain areas previously implicated in incubation of methamphetamine craving. We found no effect of sex or estrous cycle on methamphetamine self-administration and methamphetamine seeking on abstinence days 1 and 28. We also found no effect of sex or estrous cycle on the number of Fos-expressing cells in DMS or AIT-L following methamphetamine seeking test. Taken together, our results showed that methamphetamine self-administration and incubation of methamphetamine craving was not dependent on sex or estrous cycles under our experimental condition, and the role of DMS and AIT-L in incubation of methamphetamine craving may be similar across sexes and across estrous cycles in female rats.</p></div>","PeriodicalId":72067,"journal":{"name":"Addiction neuroscience","volume":"11 ","pages":"Article 100158"},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772392524000178/pdfft?md5=b425efde715176b156d81e3b1a4b212b&pid=1-s2.0-S2772392524000178-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141027990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Learning curves of episodic verbal memory tests have been used to assess learning ability in various neurocognitive disorders, but studies in alcohol-related cognitive disorders are lacking. Therefore, this study investigated California Verbal Learning Test (CVLT) learning curves in individuals with alcohol-use disorder (AUD) with and without cognitive impairments and examined associations between learning curves and changes in everyday functioning following a multicomponent care program. We fitted learning curves over the five immediate recall trials of the Dutch version of the CVLT of patients with Korsakoff's syndrome (KS; <em>N</em> = 117), alcohol-related cognitive impairment no KS (ARCI; <em>N</em> = 147), and uncomplicated AUD (<em>N</em> = 43) using a generalized non-linear mixed regression. This model was based on three different parameters: initial memory performance (attention), maximum number of correctly recalled words (maximum learning), and the increase of correctly recalled words over the trials (learning rate). Next, we related these learning curves with ratings of everyday activities using the Patient Competency Rating Scale (PCRS) before and after a care program following admission. Modelled learning curves differed across groups, with significant differences in Attention (KS&lt;ARCI&lt;AUD, <em>p</em> &lt; 0.001), Maximum Learning (KS&lt;ARCI&lt;AUD, <em>p</em>&lt;0.001), and Learning Rate (KS&lt;ARCI=AUD, <em>p</em> &lt; 0.001).

This has resulted in a deep understanding of the learning, reward, and habit-formation circuits which drive initial drug reinforcement, as well as exploration of the cognitive control and anxiety systems which are important for craving and relapse to drug use. However, most human drug users and a smaller proportion of laboratory animals are resilient to addiction, meaning that they can use addictive drugs without developing substance use disorders. Evidence from the neurobiology of resilience in stress models suggests that the mechanisms of resilience are distinct from those of vulnerability, and thus may be missed if resilience is not investigated in a targeted manner. In this review, we briefly review the limitations in our knowledge which have resulted from a focus on addiction vulnerability. We next introduce the formal construct of resilience and its historical application in neurobiology and clinical research. Finally, we present evidence for the presence of resilience mechanisms in studies of addiction neuroscience and argue for an increase in the focused study of resilience to substance abuse. By intentionally identifying compensatory resilience mechanisms in addiction, rather than only focusing on mechanisms of susceptibility, more effective therapeutic approaches may be discovered.</p></div>","PeriodicalId":72067,"journal":{"name":"Addiction neuroscience","volume":"11 ","pages":"Article 100152"},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772392524000117/pdfft?md5=27564b800d2557bedb197a04b5c68f5d&pid=1-s2.0-S2772392524000117-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140086740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Reward loss has been modeled in animals by removal from social or sexual contact, transfer from enriched to impoverished housing, or restriction of food. We previously showed that food restriction increases the unconditioned rewarding effects of abused drugs and the conditioned incentive effects of drug-paired environments. Mechanistic studies provided evidence of decreased basal dopamine (DA) transmission, adaptive upregulation of signaling downstream of D1 DA receptor stimulation, synaptic upscaling and incorporation of calcium-permeable AMPA receptors (CP-AMPARs) in medium spiny neurons (MSNs) of nucleus accumbens (NAc). These findings align with the still evolving ‘reward deficiency’ hypothesis of drug abuse. The present study tested whether a compound natural reward that is known to increase DA utilization, environmental enrichment, would prevent the persistent expression of cocaine conditioned place preference (CPP) otherwise observed in food restricted rats, along with the mechanistic underpinnings. Because nearly all prior investigations of both food restriction and environmental enrichment effects on cocaine CPP were conducted in male rodents, both sexes were included in the present study. Results indicate that environmental enrichment curtailed the persistence of CPP expression, decreased signaling downstream of the D1R, and decreased the amplitude and frequency of spontaneous excitatory postsynaptic currents (EPSCs) in NAc MSNs of food restricted male, but not female, rats. The failure of environmental enrichment to significantly decrease food restriction-induced synaptic insertion of CP-AMPARs, and how this may accord with previous pharmacological findings that blockade of CP-AMPARs reverses behavioral effects of food restriction is discussed. In addition, it is speculated that estrous cycle-dependent fluctuations in DA release, receptor density and MSN excitability may obscure the effect of increased DA signaling during environmental enrichment, thereby interfering with development of the cellular and behavioral effects that enrichment produced in males.</p></div>","PeriodicalId":72067,"journal":{"name":"Addiction neuroscience","volume":"10 ","pages":"Article 100142"},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772392524000014/pdfft?md5=ea5cbdf5e2f4717f6aee3755b8c736bb&pid=1-s2.0-S2772392524000014-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139433393","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Glial cells are critical for the proper development and function of the brain, and their reactivity is often an early signature of neurodegenerative and psychiatric disorders. Alcohol and other drugs have an impact on glial cells and promote a reactive glial state with cross-talk between neurons and glia. In this review, we summarize the major findings on the involvement of glial cells, particularly astrocytes, microglia and oligodendrocytes, in the effects of alcohol and other drugs on the brain. We focus on the contribution of imaging modalities, particularly Positron Emission Tomography (PET) and Magnetic Resonance Imaging (MRI), to understanding these mechanisms in the living brain. We analyze the role of glia in the cerebral effects of alcohol and other drugs through various ways including glutamate homeostasis, neuroinflammatory process, myelin and white matter integrity and blood-brain barrier permeability. A review of targets, radioligands, and methods used or needed in PET and MRI is presented and discussed.
