Most of the current therapeutic drugs for depression mainly achieve their antidepressant effect by tuning the landscape of neurotransmitters in the central nervous system (CNS). However, almost half of patients with MDD cannot fully benefit from these available treatments. Consequently, it is urgent to find novel therapeutic targets for the treatment of MDD. Peripheral B lymphocytes have been reported as a major contributor to the occurrence of stress-induced depression. However, the pathological role and underlying regulatory mechanism of peripheral B cells in MDD have not been well established. Here, we show that peripheral B cells are significantly infiltrated into the CNS of male mice after exposure to chronic unpredictable mild stress (CUMS). Adoptive transfer of B cells from CUMS mice into B-cell-deficient male mice could significantly induce higher severity depressive symptoms than adoptive transfer of B cells from control mice. The lack of B cells protects male mice from CUMS-induced neuroinflammation and depressive-like behaviors. Interestingly, the pathological B cells in CUMS mice are characterized by increased heme biosynthesis, whereas its inhibition can ameliorate depressive-like behaviors in B-cell-deficient mice that received pathological B cells from CUMS mice. Our findings suggest a critical role of the heme biosynthesis in B cells for contributing to the pathogenesis of depression and indicate that these pathological B cells featuring high heme may be a promising immune target for the development of precision medicine approaches in MDD.</div></div>","PeriodicalId":20851,"journal":{"name":"Progress in Neurobiology","volume":"251 ","pages":"Article 102800"},"PeriodicalIF":6.7,"publicationDate":"2025-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144335892","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to investigate the differential responses of wild-type (WT) and 5xFAD mice, a model of AD, to repeated social defeat stress (RSDS) and explore the molecular mechanisms associated with stress susceptibility. Both WT and 5xFAD mice exhibited susceptibility to initial exposure to RSDS, with a greater proportion of stress-susceptible (Sus) individuals observed in 5xFAD mice compared to WT mice. In presymptomatic 5xFAD mice repeatedly exposed to RSDS, cognitive impairment was evident through a lower discrimination index in the NOR test compared to controls. To investigate the effects of RSDS on peripheral immune responses, we performed CyTOF analysis, revealing a significant increase in CD8 + and CD4 + memory T cells exclusively in the peripheral blood of 5xFAD-Sus mice. To further explore the molecular mechanisms underlying RSDS in the brain, RNA sequencing revealed distinct patterns of differentially expressed genes associated with inflammatory pathways in stress-Sus mice. Specifically, 5xFAD-Sus mice exhibited dysregulation in immune-related pathways, while WT-Sus mice displayed alterations in pathways related to cell adhesion and cytoskeletal organization. In addition, when comparing 5xFAD-Sus to 5xFAD-resilience mice, significant disruptions in synaptic plasticity pathways were observed in 5xFAD-Sus mice, and these changes were accompanied by cognitive impairment. These findings suggest that increased stress susceptibility in 5xFAD is linked to distinct peripheral immune dysregulation, potentially contributing to synaptic plasticity impairments and cognitive dysfunction in the early stages of AD.</div></div>","PeriodicalId":20851,"journal":{"name":"Progress in Neurobiology","volume":"251 ","pages":"Article 102797"},"PeriodicalIF":6.7,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144340371","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While dopamine, a key catecholamine neurotransmitter, has been traditionally associated with neuronal functions, emerging evidence highlights its significant impact on astrocytic physiology. This review explores how astrocytes contribute to dopaminergic signaling and the implications of this interaction in both physiological and pathological contexts. Specifically, we examined astrocytic dopamine receptor expression, signaling mechanisms, and region-specific effects on neuroinflammation, synaptic regulation, and neurotrophic factor secretion. Notably, astrocytic dopamine receptor activation plays dual inflammatory roles, modulating both anti- and pro- inflammatory responses depending on the receptor subtype and pathological environment. Furthermore, dopamine-evoked gliotransmitter release and neurotrophin secretion highlight the role of astrocytes in astrocyte-to-neuron communication, which impacts synaptic plasticity and neuronal survival. Dysfunction of astrocytic dopaminergic signaling has been implicated in neurodegenerative diseases such as Parkinson’s disease, where dopamine depletion drives reactive astrogliosis, altered glutamate homeostasis, and inflammatory responses. These findings underscore the complexity of astrocytic responses to dopamine and their potential as targets in conditions characterized by dysregulation of dopaminergic signaling. By highlighting recent advancements in understanding dopamine-astrocyte interactions, this review aims to provide insights into the broader roles of astrocytes in dopaminergic systems and their therapeutic potential in CNS disorders.</div></div>","PeriodicalId":20851,"journal":{"name":"Progress in Neurobiology","volume":"251 ","pages":"Article 102798"},"PeriodicalIF":6.7,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144340370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SC LRP1 protected sensory neurons from mitochondrial dysfunction and modulated mitochondria-related biological pathways in the DRG transcriptome.

The evaluation of sociosensory cues and the modulation of motivation to engage socially are fundamental components of social interaction, thought to be coordinated by a network of interconnected brain regions called the social salience network (SSN). This network is strongly modulated by the neurohormone oxytocin (OXT) to facilitate appropriate social responses. It is increasingly recognized that disruptions within the SSN contribute to the atypical social perception and engagement observed in autistic individuals. This review will summarize evidence from current clinical and preclinical literature that provides compelling evidence for SSN disruptions as a possible mechanism that underlies the social symptoms of ASD. Furthermore, we discuss OXT-mediated correction of SSN disruptions at the regional and circuit levels that rescues social phenotypes in preclinical models of ASD-risk factors.

While many aspects of this cycle are established, a key component remains unknown: the nature of the transporter responsible for the presynaptic uptake of glutamine.

In addition, direct electrical recording of hippocampal mossy fibre boutons reveals a presynaptic glutamine transport current that is eliminated when NTT4 is removed or inhibited. The role of NTT4 in neurotransmission was demonstrated by electrophysiological recordings in hippocampal slices, which reveal that NTT4 is required to maintain vesicular glutamate content and to sustain adequate levels of glutamate supply during periods of high-frequency neuronal activity. Finally, behavioural studies in mice demonstrate a deficit in trace fear conditioning, and alterations in anxiety behaviour and social preference. These results demonstrate that NTT4 is a presynaptic glutamine transporter, which is a central component of the glutamate-glutamine cycle.
