Structural and functional insights into the lipopolysaccharide ABC transporter LptB2FG

open access: yesNature Communications, 2017
The cell surface of most Gram-negative bacteria contains lipopolysaccharide that is essential for their viability and drug resistance. A 134-kDa protein complex LptB2FG is unique among ATP-binding cassette transporters because it extracts ...

A Modular Perfusion Bioreactor Platform for Simulating Bone Regeneration and Fracture Healing: Integrating Mechanical Loading and Dual Perfusion for Advanced In Vitro Models

open access: yesAdvanced Healthcare Materials, EarlyView.
A modular bioreactor platform was developed in order to replicate bone homeostasis and pathology, thereby integrating mechanical loading, dynamic perfusion, and a 3D‐printed microfluidic chamber. With precise control of environmental parameters and dual perfusion for composite tissue models, the system enhances physiological relevance for studying bone

Borate‐Ion‐Stimulated Macrophages Promote Osteogenic Differentiation of Mesenchymal Stem Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
The immune responses of mouse macrophages stimulated by borate ions promote the osteogenic differentiation and mineralization of mouse bone marrow–derived mesenchymal stem cells in an ion‐dose‐dependent manner by providing cytokines, including BMP‐2.

Genetic Locus Required for Antigenic Maturation of \u3cem\u3eRhizobium etli\u3c/em\u3e CE3 Lipopolysaccharide [PDF]

open access: yes, 2001
Rhizobium etli modifies lipopolysaccharide (LPS) structure in response to environmental signals, such as low pH and anthocyanins. These LPS modifications result in the loss of reactivity with certain monoclonal antibodies.

A Robust Heparin‐Mimicking Polyglycerol‐Based Coating for Blood‐Contacting Devices with Long‐Term Hemocompatibility and Preliminary Anti‐Inflammatory Properties

open access: yesAdvanced Healthcare Materials, EarlyView.
A robust heparin‐mimicking coating based on sulfated polyglycerol is constructed via layer‐by‐layer assembly on bloodcontacting surfaces. The coating exhibits long‐term anticoagulant and anti‐inflammatory properties by resisting protein adsorption, preventing platelet activation, and suppressing immune responses, offering a promising strategy for ...
