Single‐Cell Transcriptome Atlas Reveals the Underlying Mechanism of Kynurenic Acid in the Regulation of Tumor Immune Microenvironment in Glioblastoma

open access: yesAdvanced Science, EarlyView.
KYNA regulates the tumor immune microenvironment in glioblastoma. KYNA reprograms the balance between T cell exhaustion and activation to suppress glioblastoma progression through inhibiting exhaustion‐associated markers (such as PD‐1, LAG3, and TOX) and enhancing immune activation and cytotoxicity markers including granzymes GZMA and GZMB.

The Tumor‐to‐Endothelial Transfer of FTO Promotes Vascular Remodeling and Metastasis in Nasopharyngeal Carcinoma

open access: yesAdvanced Science, EarlyView.
Integrated omics analysis of matched primary and liver metastatic NPC tumors reveals a unique NOTCH1+ CSC subpopulation exhibiting enhanced stemness properties and tumorigenic capacity. With in vitro and in vivo assays, exosomal transfer of tumor‐derived FTO from NOTCH1+ cells to the endothelium promotes vascular permeability and metastatic potential ...

Stress‐Induced Activation of Prolactin‐NR4A1‐Midkine Axis Exacerbates Skin Inflammation

open access: yesAdvanced Science, EarlyView.
Chronic psychological stress activates prolactin signaling to reprogram dermal fibroblasts into APCDD1+ inflammatory effectors via NR4A1, driving midkine secretion. This paracrine hub amplifies keratinocyte proliferation and immune recruitment, thus exacerbating skin inflammation.

Human Atlas of Tooth Decay Progression: Identification of Cellular Mechanisms Driving the Switch from Dental Pulp Repair Toward Irreversible Pulpitis

open access: yesAdvanced Science, EarlyView.
Tooth decay progression transforms the dental pulp response from repair to fibrosis. At early stages, stromal cells reprogram to repair the extra cellular matrix (ECM), blood vessels, and nerves, remodel and grow, keeping repair possible. In advanced decay, hypoxia, and vessel regression, in complement with an immune switch, fuel nerve degeneration and

CHB‐Induced Immune Zonation Chaos Elicited LXRα‐mediated Lipid Metabolism Disorders in Kupffer Cells to Induce Cancer Stem Cell Formation

open access: yesAdvanced Science, EarlyView.
By profiling the spatiotemporal hepatic landscape of CHB mouse models, the originally peri‐portal localized KCs migrated to the peri‐central in a CXCL9‐CXCR3‐dependent manner, facilitating their interaction with HBV+ hepatocytes. The interaction promoted LMD in KCs through ASGR1‐induced LXRα degradation, which, in turn, induced CSC formation via Stat3 ...

Drosophila medulla neuroblast termination via apoptosis, differentiation, and gliogenic switch is scheduled by the depletion of the neuroepithelial stem cell pool

open access: yeseLife
The brain is consisted of diverse neurons arising from a limited number of neural stem cells. Drosophila neural stem cells called neuroblasts (NBs) produces specific neural lineages of various lineage sizes depending on their location in the brain.

Transrectal ultrasonography of the adrenal glands in donkeys (Equus asinus) [PDF]

open access: yes, 2016
Little information is available for medical imaging in donkeys and no report about adrenal glands ultrasonography can be found in scientific literature. The feasibility of transrectal ultrasonography of the adrenal glands was tested on 30 healthy donkeys

Astrocytic PERK Deficiency Drives Prefrontal Circuit Dysfunction and Depressive‐Like Behaviors

open access: yesAdvanced Science, EarlyView.
Chen et al. show that the endoplasmic reticulum (ER) stress sensor PERK is downregulated in prefrontal cortex (PFC) astrocytes in major depressive disorder and in chronic‐stress mouse models. In young mice, astrocyte‐specific PERK loss reduces the synaptogenic cue thrombospondin‐1 (TSP1), leading to synaptic and circuit deficits and depressive‐like ...

Nanogel Integrated Zwitterionic Injectable Hydrogel with Sequential Drug‐Releasing Capability for the Programmable Repair of Spinal Cord Injury

open access: yesAdvanced Science, EarlyView.
A novel drug‐loaded D/P‐g‐PSB nanogel‐incorporated hydrogel by the electrostatic attraction‐driven self‐assembling process. Sequential drug releasing property (melatonin is released first by physical diffusion, and then ibuprofen is released as the charge shielding effect and hydrogel degradation). This ion‐sensitive hydrogel platform with sequentially
