Ultrasound‐Activated Piezoelectric Neuroimmune Hydrogel Orchestrates Neurogenesis‐Macrophage Crosstalk in Diabetic Wound Healing

open access: yesAdvanced Science, EarlyView.
In this work, we design an ultrasound‐activated piezoelectric hydrogel platform (AOEF@AP5+US) that reprograms neurogenesis‐macrophage crosstalk as an integrated strategy to overcome the intertwined barriers of chronic inflammation, peripheral neuropathy, and impaired regeneration in diabetic wounds.

Modulating Calcium Homeostasis via a Biomimetic Scaffold to Rescue Diabetic Ischemic Wounds

open access: yesAdvanced Science, EarlyView.
This strategy addresses impaired microcirculation and loss of extracellular matrix (ECM) guidance in diabetic wound healing. Musc@CP, a nanofibrous dressing combining an ECM‐mimetic chitosan‐pullulan scaffold with muscone, enhances perfusion by attenuating intracellular Ca2+ overload‐associated endothelial dysfunction.

Aberrant GRP78 Phase Transition Sustains Endothelial IRE1α Signaling and Drives Blood–Brain Barrier Failure in Cerebral Amyloid Angiopathy

open access: yesAdvanced Science, EarlyView.
Vascular Aβ40 corrupts GRP78 phase behavior in brain endothelial cells, sustaining IRE1α–TRAF2–JNK signaling and driving apoptosis, tight junction loss, and blood–brain barrier failure in cerebral amyloid angiopathy. Pharmacological IRE1α inhibition restores vascular integrity, reduces leakage, and improves functional outcomes, revealing a targetable ...

Multifunctional Manganese Oxide Nanocomposite Hydrogel With Synergistic Reactive Oxygen Species‐Scavenging, Oxygen‐Generating, Immunomodulatory, and Photothermal Antimicrobial Activities for Enhanced Diabetic Wound Healing

open access: yesAdvanced Science, EarlyView.
CFP/PC@MnO2 hydrogel integrates ROS scavenging, oxygen delivery, oxidative stress reduction, immunomodulation, and photothermal antibacterial properties. The incorporation of PC@MnO2 NPs endows the hydrogel with multiple functional advantages tailored to the pathological microenvironment of diabetic wounds, including efficient ROS clearance, mitigation

Expression of C-MYC and CD31 in Medulloblastoma

open access: yesActa clinica Croatica, 2008
Medulloblastoma is a highly malignant brain tumor of neuroectodermal origin. Changes in cell physiology that determine malignant phenotype are, among others, self-sufficiency in growth signals and angiogenesis. C-myc is a protooncogene and CD 31 is an adhesion molecule highly expressed on endothelial cells. The increased expression of c- myc is related

YAP1‐Driven Pathogenic Fibro‐Adipogenic Progenitors Secrete IL‐6 and FGF21 to Mediate Muscle‐Bone Crosstalk and Promote Bone Loss

open access: yesAdvanced Science, EarlyView.
Fibro‐adipogenic progenitors (FAPs) in atrophic muscle undergo YAP1‐driven pathogenic activation, secreting IL‐6 and FGF21 as bone‐catabolic myokines that mediate muscle‐bone crosstalk and promote bone loss. Genetic or pharmacological targeting of this YAP1‐FAP‐myokine axis rescues skeletal deterioration, identifying FAP‐derived myokines as therapeutic

AI Designed Conformation Locking Peptides Target STING to Restore Diabetic Wound Healing

open access: yesAdvanced Science, EarlyView.
A generative AI pipeline identifies SCP‐1, a conformation‐locking peptide that stabilizes inactive STING. Incorporated into a dual‐responsive hydrogel for localized, MMP‐9‐triggered release, SCP‐1 suppresses inflammation, promotes reparative macrophage polarization, and accelerates diabetic wound healing.

Endothelial YAP Signaling Promotes Blood‐Spinal Cord Barrier Repair in Mice After Spinal Cord Injury

open access: yesAdvanced Science, EarlyView.
Endothelial YAP is required for blood‐spinal cord barrier repair after spinal cord injury. YAP‐dependent vascular repair is associated with ANGPT1/PI3K/AKT signaling in vivo and may involve endothelial‐pericyte paracrine interactions. By supporting vascular remodeling, tight junction restoration, restored pericyte coverage, and astrocyte‐vascular ...

Soft Hypoxia‐Adaptive Bioelectronics Integrating PEDOT:PSS/Polydopamine/Enzyme Biocomposites for Closed‐Loop Therapeutics of Chronic Wounds

open access: yesAdvanced Science, EarlyView.
Hypoxia‐adaptive bioelectronics based on poly(3,4‐ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS)/polydopamine (PDA)/enzyme biocomposites couple O2‐centric biosensing with embedded O2 therapy to address oxygen‐deficient chronic wounds. Local O2 provision restores enzyme‐based metabolite sensing, while catalase‐mediated oxygen generation and
