Futile recanalization occurs when over half of patients fail to experience expected symptom improvement after vessel recanalization, often resulting in severe functional impairment or death. Traditionally, this phenomenon has been attributed to inadequate blood flow and reperfusion injury. More recently, ongoing neuronal death after reperfusion, which leads to the progression of the ischemic penumbra into the core infarct, has been termed “futile reperfusion.” This review explores the complex role of autophagy mechanisms in futile reperfusion following ischemic stroke, with a focus on its relationship to neuronal survival. We also examine the regulation of autophagic activity by epigenetic mechanisms. By investigating autophagy's role in ischemic stroke, we aim to identify novel pathways for precision treatment.</p>\u0000 </div>","PeriodicalId":16490,"journal":{"name":"Journal of Neuroscience Research","volume":"103 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143112962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent studies highlight the gut-liver-brain (GLB) axis and its role in PD pathogenesis. The GLB axis forms a dynamic network facilitating bidirectional communication between the gastrointestinal tract, liver, and central nervous system. Dysregulation within this axis, encompassing gut dysbiosis and microbial metabolites, is emerging as a critical factor influencing PD progression. Our understanding of PD was traditionally centered on neurodegenerative processes within the brain. However, examining PD through the lens of the GLB axis provides new insights. This review provides a comprehensive analysis of microbial metabolites, such as short-chain fatty acids (SCFAs), trimethylamine-N-oxide (TMAO), kynurenine, serotonin, bile acids, indoles, and dopamine, which are integral to PD pathogenesis by modulation of the GLB axis. Our extensive research included a comprehensive literature review and database searches utilizing resources such as gutMGene and gutMDisorder. These databases have been instrumental in identifying specific microbes and their metabolites, shedding light on the intricate relationship between the GLB axis and PD. This review consolidates existing knowledge and underscores the potential for targeted therapeutic interventions based on the GLB axis and its components, which offer new avenues for future PD research and treatment strategies. While the GLB axis is not a novel concept, this review is the first to focus specifically on its role in PD, highlighting the importance of integrating the liver and microbial metabolites as central players in the PD puzzle.</p>\u0000 </div>","PeriodicalId":16490,"journal":{"name":"Journal of Neuroscience Research","volume":"103 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142927214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many of these tasks do not require HPC function in the anterograde direction suggesting that, in the intact brain, the HPC is actively involved during all forms of learning. However, prior work has also demonstrated double dissociations of HPC and amygdala function, which is inconsistent with this view. Here, we aim to understand this discrepancy by assessing the effects of neurotoxic lesions of the HPC on anterograde and retrograde amnesia for conditioned place preference (CPP). This task is dependent on a network centered on the basolateral amygdala and not the HPC. The results show that extensive HPC damage had no impact on the acquisition or expression of CPP. One explanation for this result is that the task requires multiple, distributed training sessions for conditioning to emerge, and it has been proposed that this parameter may eliminate the need for HPC to support memory. To test this, we completed experiments to probe place learning in the Morris water task, which is thought to always require HPC function, but implemented an over-training procedure before HPC damage. We found that rats were severely impaired suggesting that this task parameter does not always allow non-HPC networks to support learning. Finally, an experiment was designed to test whether memories acquired by distinct memory networks on the same days, within hours of one another, would be linked in HPC.
