Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

open access: yesAdvanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

Configurable 3D‐Printed Microstructured Stamp as a User‐Friendly Tool for Versatile Patterning of Low‐Viscosity Bioinks

open access: yesAdvanced Materials Technologies, EarlyView.
A technique for precise patterning of highly biocompatible, low‐viscosity bioinks, such as fibrin, is crucial for recapitulating the physical organization of tissues. In this study, a configurable 3D‐printed microstructured stamp with micropillars is used to control the spatial arrangement of low‐viscosity bioinks and to assess cellular interactions ...

Integrin α8‐Mediated Pericyte Morphogenesis Controls Blood‐Brain Barrier Integrity

open access: yesAdvanced Science, EarlyView.
This study highlights that ITGA8 impacts pericyte morphology and function, both crucial for BBB integrity, via RhoA/ROCK signaling, thus influencing TGF‐β1 activation through cytoskeletal tension and ECM interactions. Notably, in post‐ischemic recovery models, ITGA8 deficiency exacerbates vascular dysfunction by impairing pericyte‐mediated BBB ...

Micrometer‐scale tPA beads amplify plasmin generation for enhanced thrombolytic therapy

open access: yesBioengineering & Translational Medicine
Rapid restoration of blood flow is critical in treating acute ischemic stroke. Current thrombolytic therapies using tissue plasminogen activator (tPA) are limited by low recanalization rates and risks of off‐target bleeding.

Loss of Fibronectin Fiber Tension in Glioblastoma is Associated with Microvascular Proliferations and Immune Cell Infiltration

open access: yesAdvanced Science, EarlyView.
Researchers discovered that fibronectin fibers lose their tension in specific areas of glioblastoma brain tumors, accumulating in the lumen of proliferating blood vessels and in parenchyma next to infiltrating immune cell clusters. A novel molecular tension probe enables the mapping of fibronectin's fiber tension in glioblastoma for the first time ...
