Spatial Transcriptomics and snRNA‐seq Expose CAF Niches Orchestrating Dual Stromal‐Immune Barriers in Hepatocellular Carcinoma

open access: yesAdvanced Science, EarlyView.
HmmyCAFs may form a triple immunosuppressive niche: possibly secrete ECM (POSTN, etc.) as physical barriers to block CD8⁺ T cells, induce CD8⁺ T exhaustion via those molecules, and use HIF‐1α‐driven metabolism to create acidic, nutrient‐poor microenvironments that suppress T cells.

The High‐Altitude Adaptation Characteristics of Microbiota‐Host Cross‐Talk in Yak Gastrointestinal Track

open access: yesAdvanced Science, EarlyView.
In this study, a single‐cell atlas of 117,019 yak gastrointestinal cells across 54 subtypes identified HNF4A and SREBF2 as key transcription factors targeting MYO6 gene. Cross‐species and multi‐omics analyses reveals epithelial cells as key regulators that, through interactions with microbes, particularly Bacillus, facilitate flexible energy supply and

Lactobacillus Salivarius‐Derived Indole‐3‐Acetic Acid Promotes AHR‐PARP1 Axis‐Mediated DNA Repair to Mitigate Intestinal Aging

open access: yesAdvanced Science, EarlyView.
Indole‐3‐acetic acid (IAA) acting as one of the aryl hydrocarbon receptor (AHR) endogenous ligands is identified to be derived from Lactobacillus salivarius via its catalytic enzyme (ALDH) rather than host cells. Lactobacillus salivarius and IAA supplementation effectively mitigate intestinal aging by facilitating AHR‐poly (ADP‐ribose) polymerase 1 ...

Reinstating Niche Failure in Diabetic Cranial Defects via Chronotaxic Signal‐Amplifying Fluidic Biomimetic Hydrogel

open access: yesAdvanced Science, EarlyView.
An in situ moldable GelSSO/PDA@SDF hydrogel functions as a chronotaxic signal‐amplifying biomimetic niche to restore regenerative failure in diabetic cranial defects. By sequentially releasing SDF‐1α‐loaded PDA nanoparticles and osteoinductive oligodeoxynucleotides, it orchestrates immunomodulation, progenitor recruitment, angiogenesis, and ...
