Targeted Inhibition of CD74+ Macrophages by Luteolin via CEBPB/P65 Signaling Ameliorates Osteoarthritis Progression

open access: yesAdvanced Science, EarlyView.
This study identifies CD74⁺ macrophages as key drivers of synovial inflammation in osteoarthritis (OA). The flavonoid luteolin is predicted to inhibit this pathway by blocking Nuclear Factor Kappa‐light‐chain‐enhancer of Activated B cells (NF‐κB) signaling. To enhance delivery, a targeted nanoplatform (MDSPL) is developed.

Procyanidin Capsules Combat ALF by Restoring Mitochondrial Homeostasis and Inhibiting Necroptosis via the PGAM5/DRP1/PINK1 Pathway

open access: yesAdvanced Science, EarlyView.
A biomimetic self‐assembly strategy, Procyanidin Capsules (PC‐Ca), has been developed, which has great stability, bioavailability, and liver‐targeting efficacy and modulates the KEAP1‐NRF2 axis to inhibit ROS formation and necroptosis, regulate mitochondrial homeostasis through the PGAM5/DRP1/PINK1 signaling pathway in thioacetamide (TAA)‐induced ALF ...

Dynamic Fibrous Hydrogels for Stem Cell Homing and In Situ Bone Regeneration

open access: yesAdvanced Science, EarlyView.
A dynamic fibrous hydrogel (DFH) is developed by covalent crosslinking of gelatin with tea‐derived trichomes, which integrates the structural and compositional fidelity of native extracellular matrix with photothermal and oxidative responsiveness, introducing a novel “stem cell recruits stem cell” strategy that orchestrates co‐homing of endogenous and ...

Bifurcate Regulation of Hematopoietic Homeostasis and Bone Osteogenesis by VHL‐HIF2α‐Controlled Adipocyte Function

open access: yesAdvanced Science, EarlyView.
The VHL‐HIF2α (VHL is Von Hippel‐Lindau) axis in adipocytes differentially regulates hematopoiesis and bone formation through stem cell factor (SCF) and chemerin, respectively. This hypoxia‐responsive pathway in adipocytes establishes a systemic signaling network with HSCs and MSCs to maintain tissue homeostasis, revealing a targetable axis for ...

Faecalibaculum rodentium Alleviates Ionizing Radiation‐Induced Damage in Mice by Improving Intestinal Integrity and Hematopoiesis via Its Metabolite Butyrate

open access: yesAdvanced Science, EarlyView.
The model shows the probiotics screening and underlying mechanisms of F. rodentiumn in alleviating IR‐induced tissue injury. Stress‐induced STAT3 mitochondria localization decreases F. rodentium abundance and butyrate concentration. Supplementation of F.

Therapeutic Reprogramming of Glioblastoma Phenotypic States Using Multifunctional Heparin Nanoparticles

open access: yesAdvanced Science, EarlyView.
This study presents heparin‐derived nanoparticles (HP‐NPs) as a novel precision medicine platform that combines therapeutic and delivery functions. HP‐NPs target drug‐resistant glioblastoma stem cells, reprogramming them into a drug‐sensitive phenotype and significantly reducing tumor progression.

Engineered Mesenchymal Stem Cell–NK Cell Complexes for Spatially Targeted and Functionally Revitalized Cancer Immunotherapy

open access: yesAdvanced Science, EarlyView.
IL‐15‐engineered stem cell–NK cell complexes, assembled via bioorthogonal chemistry, enable effective lung cancer immunotherapy. Abstract Natural killer (NK) cells represent a powerful immunotherapeutic strategy due to their intrinsic cytotoxicity and ability to target tumor cells independently of antigen presentation.

Platelet-activating factor antagonists

Clinical Reviews in Allergy, 1995
The great number of PAF antagonists reviewed in this article clearly shows the tremendous effort made in the last 20 yr to explore the complex biological background of the mechanism of action of PAF and the potential clinical benefit of its antagonists. It is obvious that now highly potent, long-acting, and perorally applicable PAF-receptor antagonists

Platelet-Activating Factor

2007
Platelet-activating factor (PAF) is a potent mediator that occurs at very low concentrations in cells and tissues. Accurate quantitation of PAF has always been difficult because of the physicochemical properties of PAF and its structural similarity to several much more abundant phospholipids.
