PLL‐g‐HPA Hydrogel Microneedles Loaded With Rhoifolin Target Macrophages to Alleviate Fibroblast Senescence for Diabetic Wound Healing

open access: yesAdvanced Healthcare Materials, EarlyView.
Diabetic wound healing is hindered by a pathological crosstalk wherein elevated IL‐11 induces M1 macrophage polarization, leading to IL‐1β/IL‐6 release and subsequent fibroblast senescence via RAS/p38MAPK/p53/E2F1 signaling. Here, we develop a Gel@M‐Rho microneedle patch that delivers rhoifolin‐loaded, macrophage membrane‐coated nanoparticles to target

Cell‐Free DNA as a Biomarker of Cell Death and Treatment Response for On‐Chip Three‐Dimensional Tumor Models

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents quantifying cell‐free DNA (cfDNA) as a non‐disruptive and rapidly quantifiable method for assessing cell death for on‐chip 3D sarcoma tumor models. On‐chip cfDNA release reflects tumor burden, extent of cell death, and survival of in vitro and ex vivo 3D models, providing valuable insight into the temporal response of tumor models ...

CD9+ B Cells Induce T Follicular Helper Cell Apoptosis to Regulate Germinal Center Regression

open access: yesAdvanced Science, EarlyView.
A unique subset of CD9+ B cells regulates germinal center B (GC‐B) cell regression by inducing T follicular helper (Tfh) cell apoptosis through multiple signaling pathways, such as ALCAM‐CD6. FOXP1 plays a key role in GC‐B cell differentiation. These findings clarify mechanisms of GC degeneration and termination and offer potential targets for adenoid ...
