- Dental pulp stem cells (DPSCs), a subset of mesenchymal stem/progenitor cells, exhibit remarkable self-renewal and multipotent differentiation capacity, making them promising candidates for regenerative applications. While their in vitro characteristics have been extensively studied, the in vivo dynamics and molecular regulation during development are much less known. This study examined the embryonic/prenatal (E16.5) and early postnatal (P3.5 and P7.5) stages of mouse molar development to trace the temporospatial expression and overlap of five key molecules associated with DPSC: a trio of positive markers (CD73/Nt5e, CD90/Thy1, and CD105/Eng) and two negative markers (CD34/Cd34 and CD45/Ptprc). Reanalysis of single-cell RNA sequencing data revealed a triple-positive and double-negative population overlapping in the dental mesenchyme by P7.5. The results were confirmed by multiple immunofluorescence-based in situ labeling. These findings contribute to the understanding of the spatiotemporal in vivo expression landscape and dynamics of DPSC markers, thus bridging the gap between in vitro characterization and the complex developmental reality of the dental pulp. - Source: PubMed

However, the complete pathogenic mechanisms underlying GAstV-2-induced hyperuricemia have not been fully elucidated. In this study, 1-day-old healthy Yangzhou goslings were orally inoculated with GAstV-2 to establish a viral infection model. The effects of GAstV-2 infection on growth performance, serum uric acid levels, cecal microbiota structure, and renal gene expression of goslings were systematically investigated. The results showed that GAstV-2 infection caused a cumulative mortality rate of 10%-30% in goslings and significantly impaired growth performance, as reflected by decreased average daily gain and average daily feed intake as well as an increased feed-to-gain ratio (P < 0.05). In addition, GAstV-2 challenge induced severe histopathological damage to the liver and kidney, disordered serum biochemical metabolism, and excessive release of pro-inflammatory cytokines, accompanied by a significant elevation in serum uric acid levels (P < 0.05). The 16S rRNA high‑throughput sequencing results confirmed that GAstV‑2 infection significantly decreased the abundances of uric acid‑degrading beneficial bacteria, including Paenibacillus polymyxa, Oscillospira guilliermondii, and Lactococcus lactis, while markedly increasing the abundance of Clostridium perfringens, which is closely associated with uric acid synthesis. Renal transcriptomic analysis confirmed that key genes involved in purine metabolism, including PRPS, IMPDH1, and NT5E, were significantly upregulated in the kidney tissues of infected goslings, which was closely correlated with the occurrence of hyperuricemia. In conclusion, GAstV-2 infection markedly inhibits growth, triggers hepatic and renal injury, increases serum uric acid and inflammatory levels, and remodels the intestinal microbiota composition and renal transcriptomic profiles in goslings. This study systematically explored the influences of GAstV-2 infection on growth performance, hepatorenal injury, and serum uric acid metabolism in goslings, and preliminarily revealed the potential underlying mechanism of GAstV-2-induced hyperuricemia by separately analyzing intestinal microbiome and renal transcriptome data. These findings provide fundamental data and a theoretical basis for further elucidating the pathogenic mechanism of GAstV-2 and developing targeted prevention and control strategies against gosling gout. - Source: PubMed

Fan JunyangMao SaiYan BingxueWang MengxiangZhang JingZhang Hongying - Extracellular purinergic signaling, mediated by nucleotides such as adenosine triphosphate (ATP) and adenosine, is a critical regulator of retinal homeostasis. Within the retina, this signaling pathway is indispensable for maintaining physiological functions. Dysregulation of extracellular purine balance is a key driver of retinal pathophysiology, contributing to inflammation, pathological angiogenesis, and neurodegeneration in diseases like diabetic retinopathy (DR), age-related macular degeneration (AMD), glaucoma, and retinopathy of prematurity (ROP). The hydrolysis of extracellular ATP to adenosine, primarily orchestrated by the sequential actions of NTPDase1/ENTPD1 (CD39) and ecto-5'-nucleotidase/NT5E (CD73), represents a fundamental mechanism for calibrating purinergic signals and shifting the microenvironment from pro-inflammatory to anti-inflammatory and protective. CD39 and CD73 are pivotal enzymes in regulating retinal purinergic equilibrium. Despite their well-characterized roles in tumor biology and cerebral pathophysiology, the expression, physiological functions, and pathological implications of CD39/CD73 in the retina remain understudied and lack systematic synthesis. This review synthesizes current understanding of the roles of CD39 and CD73 in retinal physiology and pathology, with a focus on their implications in DR, AMD, glaucoma, and ROP. Critically, this review provides the first systematic integration of their layer-specific spatial compartmentalization, context-dependent functional duality, and emerging metabolic roles in photoreceptor homeostasis. We also discuss emerging therapeutic strategies that target this pathway, addressing the growing need for translational research to preserve vision. - Source: PubMed

Chen XinyiJi JingYao JiaxinChen PengfanZhang JialiLiu LongqianWen Xiangyi - Diabetic kidney disease (DKD) is commonly staged using albumin-to-creatinine ratio (ACR) and estimated glomerular filtration rate (eGFR), yet complementary molecular markers are needed. We profiled urine and serum metabolites from 92 Korean participants (72 with type 2 diabetes and 20 healthy controls) using gas chromatography-tandem mass spectrometry (GC-MS/MS) and liquid chromatography-tandem mass spectrometry (LC-MS/MS). An exploratory restricted Boltzmann machine framework compared five DKD staging criteria and prioritized candidate metabolites; robustness was assessed against LASSO, linear support vector machine (SVM), and random forest using nested cross-validation. ACR-based staging showed the highest metabolomic discrimination. Urinary adenosine and 5'-methylthioadenosine decreased, whereas serum N2,N2-dimethylguanosine and -aconitic acid increased across ACR stages. Integration with a public renal tubular microarray dataset suggested as a cross-study network hub. These cross-sectional findings define candidate metabolite signatures associated with DKD severity and require external longitudinal validation before clinical translation. - Source: PubMed

Jung InhaPark SungjinJi MoongiPark So YoungLee Da YoungYu Ji HeeSeo Ji APaik Man-JeongPark Hyeong KyuKwon Soon HyoLee Dae HoKim Nan Hee - The underlying mechanisms of exosomes in chronic lung allograft dysfunction (CLAD) remain poorly understood. The primary challenge lies in the substantial functional heterogeneity of exosomes in CLAD. In this study, lung transplantation was initially performed, followed by the generation of a chronic rejection (CR) model in rats to simulate CLAD in humans. Exosomes from lung graft tissues were extracted, purified, and subjected to proximity barcoding assay-based single-vesicle membrane proteomic profiling. Additionally, bulk proteomic and metabolomic profiling of the graft tissues was conducted. Exosomes were categorized into 14 clusters. Compared with the syngeneic group, the CR group had significantly lower levels of clusters 7 (Nphs1), 13 (Aqp1), and 14 (Csf3r), and higher levels of clusters 2 (Lrp2 Mrc1) and 4 (Nt5e). The abundance of cluster 12 (Ilk) exosomes was strongly correlated with pleural thickness (r = -0.90, P < 0.001). Cluster 12 exosomes exhibited the greatest number of related differentially expressed proteins and metabolites. The proteins correlated with cluster 12 were enriched in the "complement and coagulation cascades", whereas the metabolites were enriched in the "glycerophospholipid metabolism". Further verification in patients with restrictive allograft syndrome revealed the same decrease in abundance of cluster 12 exosomes as that observed in the rat model. Finally, the core molecular network of cluster 12 that contributes to pleural thickening in CLAD was constructed. In this study, the heterogeneous composition of exosomes in lung grafts was mapped to expand the understanding of their effects and to drive their application in CLAD. - Source: PubMed
