Time‐Dependent Therapeutic Effect of S‐Ketamine on PTSD Mediated by VTA‐OFC Dopaminergic Neurocircuit

open access: yesAdvanced Science, EarlyView.
This study reveals that early rather than late administration of S‐ketamine can ameliorate PTSD symptoms. This phenomenon is attributed to reversing the progressive inhibition of VTADA neurons and the function of VTADA‐OFC circuit following stress. Targeted stimulation of the OFC by TI‐NIBS to enhance DA release effectively extends the therapeutic time

5’‐Methylthioadenosine Metabolic Reprogramming Drives H3K79 Monomethylation‐Mediated PAK2 Upregulation to Promote Cadmium‐Induced Breast Cancer Progression by Impairing Autophagic Flux

open access: yesAdvanced Science, EarlyView.
Cadmium, a carcinogenic heavy metal, drives breast cancer progression via metabolic reprogramming and autophagic flux disruption. Multi‐omics revealed cadmium‐induced 5'‐methylthioadenosine depletion activates DOT1L‐mediated H3K79me1 at PAK2 promoter, upregulating PAK2 to block autophagy and driving malignancy. Clinically, 5'‐methylthioadenosine levels

PRDM16 Reduces Cellular Senescence by Upregulating GSTM1

open access: yesAdvanced Science, EarlyView.
Cellular senescence drives aging and aging‐related organ disorders, yet PRDM16's role remains unexplored. This work uncovers that PRDM16 decreases significantly in aged organs, while its loss accelerates cellular senescence and aging‐related organ injury.

Cinobufagin Directly Targets PDE4D to Disrupt Fibroblast–Dendritic Cell Crosstalk in Atopic Dermatitis

open access: yesAdvanced Science, EarlyView.
Single‐cell RNA sequencing revealed that MIF signaling drives inflammatory fibroblastmyeloid cell crosstalk in atopic dermatitis. Cinobufagin, a potent PDE4D inhibitor, suppresses MIF and reduces inflammation by restoring the cAMP/PKA/CREB pathway. Genetic knockout validates PDE4D as a key driver and promising therapeutic target for atopic dermatitis ...

The cytoplasmic domain of CD4 promotes the development of CD4 lineage T cells. [PDF]

open access: yes, 1996
Thymocytes must bind major histocompatibility complex (MHC) proteins on thymic epithelial cells in order to mature into either CD8+ cytotoxic T cells or CD4+ helper T cells.

Single‐Cell Transcriptomics Unravels Growth Factor Erv1‐Like Mediated Ferroptosis as a Key Driver of Intestinal Epithelial Dysfunction in Ulcerative Colitis

open access: yesAdvanced Science, EarlyView.
Single‐cell transcriptomic profiling of ulcerative colitis (UC) tissues identified downregulation of GFER in intestinal epithelial cells. Mechanistically, GFER interacts with PCBP1 to help maintain intracellular iron homeostasis and may also reduce lipid peroxidation by activating the PGC‐1α/PPARγ signaling pathway, thereby inhibiting ferroptosis ...

Laser Ultrasound Super‐Resolution Imaging for Multi‐Parametric Non‐Invasive Volumetric Characterization of Brain Cancer

open access: yesAdvanced Science, EarlyView.
Laser ultrasound super‐resolution imaging (LUSSI) leverages laser‐generated ultrasound for functional 3D transcranial imaging of brain tumor vasculature. Combined with optoacoustic tomography, it is demonstrated in a glioblastoma model, revealing structural abnormalities, compressed vessels, hemorrhages, and hypoxic regions.

In vivo evidence for NMDA receptor mediated excitotoxicity in a murine genetic model of Huntington Disease [PDF]

open access: yes, 2008
N-methyl-D-aspartate receptor (NMDAR) mediated excitotoxicity is implicated as a proximate cause of neurodegeneration in Huntington Disease (HD). However, this hypothesis has not been tested rigorously in vivo. NMDAR NR2B-subunits are the predominant NR2

Single‐Cell Transcriptome Analysis Reveals That Hmga2 Regulates Neuroinflammation and Retinal Function by Modulating Müller Cell Autophagy Through PI3K/AKT Signaling Following MCAO‐Induced Retinal Ischemia

open access: yesAdvanced Science, EarlyView.
Employing snRNA‐seq post‐MCAO‐induced retinal ischemia (RI), this study revealed a novel Hmga2‐high Müller cell subpopulation. Hmga2 knockout alleviated neuroinflammation and RI symptoms, potentially by binding PI3K and regulating Müller cell autophagy.
