CCN1 Enhances Tumor Immunosuppression through Collagen‐Mediated Chemokine Secretion in Pancreatic Cancer

open access: yesAdvanced Science, EarlyView.
CCN1 modulates the tumor microenvironment in pancreatic cancer by promoting collagen‐dependent chemokine production, thereby facilitating immune evasion. Deletion of CCN1 not only suppresses tumor growth but also enhances immune cell infiltration and increases tumor sensitivity to both chemotherapy and immunotherapy.

3D‐Printed Titanium Trabecular Scaffolds with Sustained Release of Hypoxia‐Induced Exosomes for Dual‐Mimetic Bone Regeneration

open access: yesAdvanced Science, EarlyView.
This study presents 3D‐printed Ti‐6Al‐4V trabecular scaffolds combined with hypoxia‐induced exosomes encapsulated in PEGDA/GelMA microspheres for sustained release. The scaffolds mimic the structure of natural bone, while the exosome delivery system enhances osteogenesis and angiogenesis, significantly promoting bone regeneration and offering a ...

An Intelligent and Conductive Hydrogel with Multiresponsive and ROS Scavenging Properties for Infection Prevention and Anti‐Inflammatory Treatment Assisted by Electrical Stimulation for Diabetic Wound

open access: yesAdvanced Science, EarlyView.
This study introduces a novel therapeutic approach that employs a conductive hydrogel (HEPP) responsive to near‐infrared light, pH levels, and reactive oxygen species. Its goal is to enhance the healing environment affected by elevated glucose levels, insufficient oxygen, and bacterial infections in diabetes‐related wounds.

Ultrasound‐Triggered Nanocomposite “Lever” Hydrogels with a Full Repair System Accelerates Diabetic Foot Ulcer Repair

open access: yesAdvanced Science, EarlyView.
Ultrasound (US)‐treated nanocomposite ‘lever’ hydrogels reprogrammed wound reactive oxygen species (ROS) levels and promoted wound healing in infected diabetic foot ulcers. Abstract Diabetic foot ulcers (DFUs) are a complex mixture of neuropathy, peripheral arterial disease, and infection, where excessive reactive oxygen species (ROS) exacerbates ...

The Role of MCPIP1 in Macrophage Polarization and Cardiac Function Post‐Myocardial Infarction

open access: yesAdvanced Science, EarlyView.
Following myocardial infarction, MCPIP1 deficiency in macrophages triggers ferroptosis, driving proinflammatory M1 dominance over reparative M2 phenotypes. This imbalance amplifies splenic monocyte release and sustains cardiac inflammation. Concurrently, excessive inflammatory mediators and insufficient TGF‐β impair fibroblast activation, delaying ...

Oxytocin‐Mediate Modulation of Splenic Immunosuppression in Chronic Social Stress Through Neuroendocrine Pathways

open access: yesAdvanced Science, EarlyView.
Chronic social stress elevates oxytocin levels, leading to immunosuppression by enhancing regulatory T‐cell activity and promoting anti‐inflammatory macrophage polarization in the spleen. Blocking oxytocin signaling reverses these effects but worsens stress‐induced behavioral disorders and reduces survival rates. This highlights oxytocin's dual role in

Smart Organic–Inorganic Copolymer Nanoparticles Distinguish Between Microglia and Cancer Cells for Synergistic Immunotherapy in Glioma

open access: yesAdvanced Science, EarlyView.
The tumor microenvironment‐responsive nanoagonists are developed using an organic–inorganic copolymer composed of the polymer (PC6AB) and manganous phosphate ionic oligomers (MnP). PC6AB with membranolytic activity selectively interacts with tumor cell membranes to induce immunogenic cell death, while MnP activates the STING pathway in immune cells ...
