The BLA contains numerous cell types which can broadcast information into structures that may elicit changes in emotional states and behaviors.

The role of <i>Drd1+</i> or <i>Drd2</i>+ BLA neurons in learned and unlearned emotional responses is unknown. Here, we identified that the <i>Drd1</i>+ and <i>Drd2</i>+ BLA neuron populations form two parallel pathways for communication with the ventral striatum.

Further, through two separate behavioral assays, we found that the <i>Drd1</i>+ and <i>Drd2</i>+ parallel pathways distinctly influence both learned and unlearned emotional states when they are activated or suppressed and do so depending upon where they synapse in the ventral striatum – with unique contributions of <i>Drd1</i>+ and <i>Drd2</i>+ circuitry on negative emotional states.

Notably, cognitive phenotyping in AD mouse models has yielded inconsistent results. In this study, we characterized the age-dependent trajectory of phenotypes in 5xFAD mice on a congenic C57BL/6 J background. These mice harbor five familial AD (FAD)-related mutations in the amyloid precursor protein (APP) and presenilin 1 (PSEN1) genes. Aβ plaque deposition was detected in specific brain regions by 4 months of age, but cognitive performance remained intact at this stage. However, by 8–9 months, these mice developed impairments in spatial working memory, novel object recognition memory, and social recognition memory. By 11 months, they also showed metabolic alterations, including lower body weight, higher energy expenditure and increased locomotor activity. Furthermore, after 10 days of chronic social isolation-unpredictable stress, 4-month-old 5xFAD mice exhibited cognitive deficits, accompanied by increased Aβ accumulation in the medial prefrontal cortex, hippocampus, and entorhinal cortex. In contrast, age- and sex-matched wild-type littermate controls subjected to the same stress paradigm showed no significant cognitive changes. These observations suggest that Aβ deposition increases stress vulnerability in 5xFAD mice.

While most disease-causal mutations of APP occur within the Aβ-coding region or immediately proximal, the pathological impacts of mutations in the N-terminus of APP protein, which remote from the Aβ sequence, on neuron and synapse are still largely unknown. It was recently reported a pathogenic APP N-terminal Val225Ala mutation (APP<sub>V225A</sub>) with clinically featuring progressive dementia and typical AD pathologies in brain. In our present study, we further found that APP<sub>V225A</sub> mutation alters the N-terminal structure of APP, which enhances its binding affinity to tau protein and significantly increases APP-mediated endocytosis. Consequently, APP<sub>V225A</sub> promotes the uptake of extracellular tau into SH-SY5Y cells, further linking the structural change in APP to intracellular tau accumulation. In addition, APP<sub>V225A</sub> also notably alters the liquid-liquid phase separation (LLPS) of intracellular tau and intensified tau phosphorylation and aggregation in SH-SY5Y cells. Moreover, APP<sub>V225A</sub> promote AD-like tau pathology and synaptic damages in human induced pluripotent stem cells (hiPSCs)-derived neural progenitor cells and neurons, as well as in hiPSCs-derived human brain organoids and mouse brain, which can be ameliorated by tau knockdown. Proximity labeling identified several key APP<sub>V225A</sub>-interacting proteins, including HS3ST3A1, which was shown to directly regulate tau LLPS and phosphorylation. These findings nicely build on our previous work on roles for APP in tau-related pathological phenotypes and further highlight the involvement of N-terminal APP as the key region for both amyloidopathy and tauopathy, two aspects of AD pathogenesis and progression. Our study may also provide a theoretical breakthrough for AD therapy and highlight the important hub roles of APP and making previously neglected N-terminal APP as a potential target for the discovery of novel disease-modifying therapeutic agents against AD, holding significant scientific values and clinical promise.</p>","PeriodicalId":19008,"journal":{"name":"Molecular Psychiatry","volume":" ","pages":"2316-2334"},"PeriodicalIF":9.6,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142668405","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
