Taurocholic Acid Is Associated With Disturbed Functional Connectivity in the Hippocampus of Patients With Depression

Advanced Science, EarlyView.
This study identifies elevated taurocholic acid (TCA) in Major Depressive Disorder patients. Gut microbiome‐associated TCA impairs hippocampal neurogenesis, triggers microglia activation, and elicits depression‐like behavior in mice via the S1PR2. In patients, functional neuroimaging reveals that serum TCA levels correlate with altered functional ...

A Patient‐Derived Organ‐on‐Chip Platform for Modeling the Tumor Microenvironment and Drug Responses in Pancreatic Cancer

Advanced Science, EarlyView.
Researchers have developed a patient‐derived organ‐on‐a‐chip model for pancreatic cancer by integrating cancer cells with supportive stromal and immune cells inside a microfluidic device. This system mimics the tumor microenvironment, enabling personalized testing of chemotherapy and immunotherapy, and offering new insights into how targeting ...

Stabilized Ion Selectivity Corrects Activation Drift in Kalium Channelrhodopsins

Advanced Science, EarlyView.
As newly emerged optogenetic tools, potassium channelrhodopsins (KCRs) can drift from inhibition to activation during illumination as K⁺ selectivity declines. It is shown that both the absolute K⁺/Na⁺ permeability ratio and its stability over time govern this drift, identify KCR1‐C29D as a reliably inhibitory variant, and outline design principles for ...

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

Advanced 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 ...

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

Advanced 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 ...
