However, whether their control of homeostatic and non-homeostatic feeding behaviors is mediated via shared or separate neural circuits is not well understood. Given that NTS A2 neurons project to the lateral hypothalamus (LH), a brain region implicated in both homeostatic and non-homeostatic feeding, this study examined whether NTS A2 neurons project to LH (A2<sup>NTS→LH</sup>) to control these feeding behaviors. We used chemogenetics to activate A2<sup>NTS→LH</sup> neurons. To assess homeostatic feeding, we measured chow intake in the home cage for 24 h and to assess non-homeostatic feeding, we used the Pavlovian appetitive conditioning task to measure cue-induced appetitive behavior. Using anatomical tracing, we first showed that ~20% of NTS A2 neurons project to the LH and these LH-projecting NTS A2 neurons are activated by food intake. Chemogenetic activation of A2<sup>NTS→LH</sup> neurons significantly suppressed home cage chow intake and body weight. However, while activation of all NTS A2 neurons suppressed cue-induced appetitive behavior, pathway specific stimulation of A2<sup>NTS→LH</sup> neurons did not affect this cue-driven behavior. Together, these results indicate that the A2<sup>NTS→LH</sup> neurons are involved in the control of homeostatic food intake but not cue-induced appetitive behaviors, and suggest the contribution of distinct NTS A2 pathways and LH neurons in the regulation of homeostatic and non-homeostatic feeding behaviors.</p>","PeriodicalId":16535,"journal":{"name":"Journal of Neuroendocrinology","volume":"38 7","pages":""},"PeriodicalIF":5.0,"publicationDate":"2026-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jne.70229","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148411555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In zebrafish, GnRH3 serves as the hypophysiotropic isoform. Its neurons develop by migrating from the nasal placode to the hypothalamus, forming several distinct subpopulations along the migratory path. However, the molecular heterogeneity underlying this migration remains incompletely understood. To delineate the molecular and spatial heterogeneity, we employed single-nuclei RNA sequencing of nuclei enriched based on <i>gnrh3</i> promoter-driven EGFP fluorescence from 7 dpf <i>Tg(gnrh3:EGFP)</i> zebrafish. This was followed by GnRH3 neurons clustering, differentially expressed genes identification, trajectory inference as a hypothesis-generating framework, and functional analyses. Marker genes were selected and used for validation and to determine the distribution of each subcluster by in situ hybridization (ISH) and immunohistochemistry (IHC) in larval and adult zebrafish. Three subpopulations were identified featuring highly expressed marker genes: Gnrh3<sup>cyp1a</sup>, Gnrh3<sup>nrg1</sup>, and Gnrh3<sup>npffl/prl2</sup>. Gnrh3<sup>npffl/prl2</sup> was further clustered into two subpopulations, Gnrh3<sup>npffl/prl2</sup> and Gnrh3<sup>npffl</sup>, which localized in the olfactory bulbs/terminal nerve and telencephalon, whereas Gnrh3<sup>cyp1a</sup> and Gnrh3<sup>nrg1</sup> were detected in distinct cells within the olfactory epithelium. Trajectory inference and gene ontology enrichment analyses were consistent with a putative transcriptomic continuum from Gnrh3<sup>cyp1a</sup> to Gnrh3<sup>npffl/prl2</sup> states, with the latter subpopulation lacking canonical migratory gene signatures. Protein–protein interaction network analysis revealed interaction relationships among differentially expressed genes, with a GnRH3-associated interaction module further supporting the selection of the above marker genes.

However, molecular markers that reliably distinguish these neuronal subtypes across hypothalamic regions remain undefined. Recent single-cell transcriptomic studies suggest that <i>Calb1</i> and <i>Reln</i> are differentially expressed in magnocellular and parvocellular OXT-synthesizing neurons in the hypothalamic paraventricular nucleus (PVN). Whether this molecular distinction extends to OXT neurons beyond the PVN or to AVP neurons has remained unclear. Fluorogold (FG) was administered to adult male C57BL/6J mice via tail vein injection. Calbindin 1 and reelin expression in OXT- and AVP-synthesizing neurons in the bed nucleus of the stria terminalis (BNST), PVN, supraoptic nucleus (SON), and retrochiasmatic supraoptic nucleus (SOR) was examined by immunocytochemistry. FG-labeled neurons were distributed in the PVN, SON, and SOR. Most OXT-immunoreactive (ir) neurons in the anterior PVN, SON, and SOR were FG-positive, whereas many OXT-ir neurons in the posterior PVN were FG-negative. Most FG-positive OXT-ir neurons showed calbindin 1 immunoreactivity. Two-thirds of FG-negative OXT-ir neurons in the posterior PVN expressed reelin. Almost all Reln-positive OXT-ir neurons were FG-negative. Nearly all AVP-ir neurons were FG-positive, and more than half expressed calbindin 1, whereas reelin expression was not detected. In corticotropin-releasing hormone (CRH)-Venus knock-in mice, AVP-ir neurons and CRH-positive neurons were not colocalized within the PVN, and AVP-ir and CRH-positive fibers were localized to distinct layers of the median eminence. These findings indicate that AVP expression in parvocellular CRH neurons was below the detection threshold of the methods used in this study. Calbindin 1 serves as a marker for magnocellular OXT neurons, whereas reelin identifies a subset of parvocellular OXT neurons. Given that the detected AVP-ir neurons were predominantly magnocellular, calbindin 1 labels a subset of this magnocellular AVP population.

We previously showed that a systemic salt challenge triggers inverse neurovascular coupling (iNVC) in the SON, in which activity-dependent dendritic AVP release induces parenchymal arteriole (PA) vasoconstriction and local hypoxia. In heart failure (HF), however, the polarity of this salt-evoked response is reversed: microglia-derived adenosine acting on A2A receptors overrides an enhanced AVP-mediated vasoconstriction, producing net vasodilation. Still, whether AVP activation by non-osmotic stimuli engages similar neurovascular mechanisms is unknown. Here, we examined whether hypovolemia induced by intraperitoneal polyethylene glycol (PEG) evokes comparable vascular responses in control and HF rats. In vivo two-photon imaging was used to assess PA diameter in response to PEG in HF rats. Plasma protein and osmolarity were measured using the nanodrop ultra spectrophotometer and osmometer respectively. PEG produced a sustained rise in plasma protein concentration without altering plasma osmolality, confirming induction of isosmotic hypovolemia, and evoked vasoconstriction of SON PA in both control and sham rats. In HF rats, PEG still induced vasoconstriction at 60 min, but this response was attenuated by 90 min despite persistent hypovolemia. These findings indicate that hypovolemia engages a vasoconstrictive neurovascular response consistent with the iNVC previously shown to be AVP-mediated during osmotic stimulation, and that this response remains largely intact in HF. The polarity and temporal dynamics of NVC in HF appear to be stimulus-dependent, shaped both by osmotic-specific recruitment of purinergic pathways and by the altered physiological milieu imposed by HF.</p>","PeriodicalId":16535,"journal":{"name":"Journal of Neuroendocrinology","volume":"38 7","pages":""},"PeriodicalIF":5.0,"publicationDate":"2026-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148396971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this review is to identify specific cognitive differences between women with PMOS and those without, highlight gaps in current research and clinical care, and inform the development of more comprehensive care frameworks for individuals with PMOS.

Twenty-two studies involving 136,008 women with PMOS and 333,895 without PMOS were included. Across cognitive domains, pooled correlations generally indicated small, non-significant negative associations, including executive function (<i>r</i> = −0.12, 95% confidence interval [CI] –0.26 to 0.02), attention (<i>r</i> = −0.13, 95% CI –0.38 to 0.14), and working memory (<i>r</i> = −0.14, 95% CI –0.31 to 0.05). Substantial heterogeneity was observed in several domains, often driven by individual outlying studies. Risk of bias was generally low, and funnel plots with Egger's regression provided no evidence of publication bias.
