To test this hypothesis, we stimulated 5-HT7R with the selective agonist LP-211 to investigate its possible beneficial effects on synaptic dysfunctions and altered behavior in the AS mice model. In mutant mice, we observed impairment of the synaptic machinery of protein synthesis, which was reversed by 5-HT7R activation. Moreover, stimulation of 5-HT7R was able to: i) enhance dendritic spine density in hippocampal neurons, which was reduced in AS mice; ii) restore impaired long-term potentiation (LTP) in hippocampal slices of the AS mice; iii) improve cognitive performance of the mutant animals subjected to the fear conditioning paradigm. Altogether, our results, showing beneficial effects of 5-HT7R stimulation in restoring molecular and cognitive deficits associated with AS, suggest that targeting 5-HT7R could be a promising therapeutic approach for the pathology.</div></div>","PeriodicalId":20851,"journal":{"name":"Progress in Neurobiology","volume":"242 ","pages":"Article 102684"},"PeriodicalIF":6.7,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142558610","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite their significant role in regulating spine structure, the role of ERM proteins in the nucleus accumbnes (NAcc) is not well known, especially in in the context of risk-reward decision-making. Here, we measured the relationship between synaptic excitation and inhibition (E/I ratio) from medium spiny neurons in the NAcc core obtained in the rat after a rat gambling task (rGT). Then, after surgery of a phosphomimetic pseudo-active mutant form of radixin (Rdx-T564D) in the NAcc core, we examined its role in synaptic plasticity and the accompanying risk-choice behavior in rGT. We found that basal E/I ratio in the NAcc core was higher in risk-averse rats than risk-seeking rats. However, it was significantly reduced in risk-averse rats similar to that in risk-seeking rats in the presence of Rdx-T564D in the NAcc core. Furthermore, the head sizes of spines were shifted in risk-averse rats expressing Rdx-T564D in the NAcc core, similar to those observed in risk-seeking rats. The effects of Rdx-T564D in risk-averse rats were again manifested as behavioral changes, with reduced selection of optimal choices and increased selection of disadvantageous ones. In this study, we demonstrated that manipulation of radixin phosphorylation status in the NAcc core can alter glutamatergic synaptic transmission and spine structure at this site, as well as risk choice behaviors in the rGT.

We have denoted this the “threshold theory” to account for how PD symptoms develop in sequence. In this perspective, threshold functions are delineated in a quantitative, synaptic, and cellular network context. This provides a framework to discuss the development of specific symptoms. PD includes dysfunction and degeneration in many organ systems and both peripheral and central nervous system involvement. The threshold theory accounts for and explains the reasons why parallel gradually emerging pathologies in brain and peripheral systems generate specific symptoms only when functional thresholds are crossed, like tipping points. New and mounting evidence demonstrate that PD and related neurodegenerative diseases are multisystem disorders, which transcends the traditional brain-centric paradigm.

Currently, there is a lack of in-vivo data from humans and rodents that elucidate if, and how, sleep renormalizes information processing capacities. From an information-theoretical perspective, a consolidation process should entail a reduction in neural pattern variability over the course of a night. Here, in a cross-species intracranial study, we identify a tradeoff in the neural population code during sleep where information coding efficiency is higher in the neocortex than in hippocampal archicortex in humans than in rodents as well as during wakefulness compared to sleep. Critically, non-REM sleep selectively reduces information coding efficiency through pattern repetition in the neocortex in both species, indicating a transition to a more robust information coding regime. Conversely, the coding regime in the hippocampus remained consistent from wakefulness to non-REM sleep. These findings suggest that new information could be imprinted to the long-term mnemonic storage in the neocortex through pattern repetition during sleep. Lastly, our results show that task engagement increased coding efficiency, while medically-induced unconsciousness disrupted the population code. In sum, these findings suggest that neural pattern variability could constitute a fundamental principle underlying cognitive engagement and memory formation, while pattern repetition reflects robust coding, possibly underlying the consolidation process.</div></div>","PeriodicalId":20851,"journal":{"name":"Progress in Neurobiology","volume":"242 ","pages":"Article 102672"},"PeriodicalIF":6.7,"publicationDate":"2024-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142381493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
