Noroviruses(NoVs) are the main cause of viral gastroenteritis outbreaks worldwide, and oysters are the most common carriers of NoV contamination and transmission. NoVs bind specifically to oyster tissues through histo-blood group antigens(HBGAs), and this facilitates virus accumulation and increases virus persistence in oysters. To investigate the interaction of HBGAs in Pacific oysters with GⅡ.4 NoV, we examined HBGAs with ELISAs and investigated binding patterns with oligosaccharide-binding assays using P particles as a model of five GⅡ.4 NoV capsids. The HBGAs in the gut and gills exhibited polymorphisms. In the gut, type A was detected(100%), whereas type Leb(91.67%) and type A(61.11%) were both observed in the gills. Moreover, we found that seasonal NoV gastroenteritis outbreaks were not significantly associated with the specific HBGAs detected in the oyster gut and gills. In the gut, we found that strain-2006 b and strain-96/96 US bound to type A and H1 but only weakly bound to type Leb; in contrast, the Camberwell and Hunter strains exhibited weak binding to types H1 and Ley, and strain-Sakai exhibited no binding to any HBGA type. In the gills, strain-96/96 US and strain-2006 b bound to type Leb but only weakly bound to type H1; strains Camberwell, Hunter, and Sakai did not bind to oyster HBGAs. Assays for oligosaccharide binding to GⅡ.4 NoV P particles showed that strain-95/96 US and strain-2006 b strongly bound to type A, B, H1, Leb, and Ley oligosaccharides, while strains Camberwell and Hunter showed weak binding ability to type H1 and Ley oligosaccharides and strain-Sakai showed weak binding ability to type Leb and Ley oligosaccharides. Our study presents new information and enhances understanding about the mechanism for NoV accumulation in oysters. Further studies of multiple NoV-tissue interactions might assist in identifying new or improved strategies for minimizing contamination, including HBGA-based attachment inhibition or depuration.

Single-cell and spatial omics:exploring hypothalamic heterogeneity

Neural Regeneration Research 2025年第6期20卷 1525-1540页

Elucidating the complex dynamic cellular organization in the hypothalamus is critical for understanding its role in coordinating fundamental body functions. Over the past decade, single-cell and spatial omics technologies have significantly evolved, overcoming initial technical challenges in capturing and analyzing individual cells. These high-throughput omics technologies now offer a remarkable opportunity to comprehend the complex spatiotemporal patterns of transcriptional diversity and cell-type characteristics across the entire hypothalamus. Current single-cell and single-nucleus RNA sequencing methods comprehensively quantify gene expression by exploring distinct phenotypes across various subregions of the hypothalamus. However, single-cell/single-nucleus RNA sequencing requires isolating the cell/nuclei from the tissue, potentially resulting in the loss of spatial information concerning neuronal networks. Spatial transcriptomics methods, by bypassing the cell dissociation, can elucidate the intricate spatial organization of neural networks through their imaging and sequencing technologies. In this review, we highlight the applicative value of single-cell and spatial transcriptomics in exploring the complex molecular-genetic diversity of hypothalamic cell types, driven by recent high-throughput achievements.

The brain's extracellular matrix(ECM),which is comprised of protein and glycosaminoglycan(GAG)scaffolds,constitutes 20%-40% of the human brain and is considered one of the largest influencers on brain cell functioning(Soles et al.,2023).Synthesized by neural and glial cells,the brain's ECM regulates a myriad of homeostatic cellular processes,including neuronal plasticity and firing(Miyata et al.,2012),cation buffering(Moraws ki et al.,2015),and glia-neuron interactions(Anderson et al.,2016).Considering the diversity of functions,dynamic remodeling of the brain's ECM indicates that this understudied medium is an active participant in both normal physiology and neurological diseases.

华北克拉通和巴西圣弗朗西斯科-刚果克拉通新元古代早期的岩墙和岩床及玄武岩(ca.940~890Ma)岩浆活动时间对比和古地磁研究结果表明,上述克拉通在新元古代可能相邻。这些阶段性岩浆作用的演化趋势和源区特征及其所反映的地质过程与构造背景对进一步开展大陆重建有重要意义。本文系统总结和对比分析了两个克拉通新元古代镁铁质岩石的岩相学、地球化学和同位素年代学数据。研究发现,这些岩石大致可分为两类多期:(1)年龄较老(ca.940~920Ma)且演化的高Ti岩石(MgO2%),负Eu异常明显(Eu/Eu^(*)=0.7~1.0);(2)年龄较年轻(ca.915~890Ma)且较为原始的低Ti岩石(MgO>6.5%,TiO_(2)<2%),具有正Eu异常(Eu/Eu^(*)=1~1.2)或者没有Eu异常(Eu/Eu=1)。早期高Ti岩浆源区类似于EMⅠ型地幔端元(ε_(Nd)(t)=-8~+3),Sr-Nd同位素特征表明其可能是软流圈上涌熔融产生的岩浆与岩石圈地幔相互作用的结果;而晚期低Ti岩石Nd同位素与球粒陨石值类似(ε_(Nd)(t)=-2~+3),可能来源于软流圈地幔。这两类岩石在华北克拉通和巴西圣弗朗西斯科-刚果克拉通几乎同时出现,且可类比。岩浆演化趋势、微量元素和Sr-Nd同位素等特征及单斜辉石-熔体平衡深度计算表明,早期高Ti岩浆产生于大陆岩石圈破裂初期,经历了较高程度的结晶分异作用;而晚期低Ti岩浆的持续作用(~30Myr)可能与岩石圈破裂过程中不断增强的软流圈岩浆活动相关。该裂谷演化进程在Sr同位素特征变化上也有体现,即与早期高Ti岩石相比,晚期低Ti岩石的Sr同位素更为富集但Nd同位素保持不变,表明该类岩石的产生可能在大陆裂谷发育过程中受到海水蚀变的影响。以上证据表明,华北克拉通和巴西圣弗朗西斯科-刚果克拉通在新元古代早期具有可类比的岩石圈应力演化状态,且经历了相似的地幔地球化学动力学过程,支持两个克拉通在该时期相邻。

Neural Regeneration Research 2025年第3期20卷 763-778页

Meningeal lymphatic vessels form a relationship between the nervous system and periphery, which is relevant in both health and disease. Meningeal lymphatic vessels not only play a key role in the drainage of brain metabolites but also contribute to antigen delivery and immune cell activation. The advent of novel genomic technologies has enabled rapid progress in the characterization of myeloid and lymphoid cells and their interactions with meningeal lymphatic vessels within the central nervous system. In this review, we provide an overview of the multifaceted roles of meningeal lymphatic vessels within the context of the central nervous system immune network, highlighting recent discoveries on the immunological niche provided by meningeal lymphatic vessels. Furthermore, we delve into the mechanisms of crosstalk between meningeal lymphatic vessels and immune cells in the central nervous system under both homeostatic conditions and neurodegenerative diseases, discussing how these interactions shape the pathological outcomes. Regulation of meningeal lymphatic vessel function and structure can influence lymphatic drainage, cerebrospinal fluid-borne immune modulators, and immune cell populations in aging and neurodegenerative disorders, thereby playing a key role in shaping meningeal and brain parenchyma immunity.
