Integrin-mediated membrane blebbing is dependent on the NHE1 and NCX1 activities. [PDF]

open access: yes, 2011
Integrin-mediated signal transduction and membrane blebbing have been well studied to modulate cell adhesion, spreading and migration^1-6^. However, the relationship between membrane blebbing and integrin signaling has not been explored.

pH regulatory Na/H exchange by Amphiuma red blood cells. [PDF]

open access: yes, 1994
In Amphiuma red blood cells, the Na/H exchanger has been shown to play a central role in the regulation of cell volume following cell shrinkage (Cala, P. M. 1980. Journal of General Physiology.

Asymmetric Cu─N─Ru Bridgedsite Nanozyme‐Loaded Injectable Thermogel Boosts Cuproptosis‐Like Death for Multidrug‐Resistant Urinary Tract Infections

open access: yesAdvanced Science, EarlyView.
To address multidrug‐resistant urinary tract infections (MDR‐UTIs), we developed Cu‐ZIF8‐Ru nanozyme featuring an asymmetric Cu─N─Ru catalytic site. This unique structure enhances multienzyme‐mimetic activity, eradicating resistant bacteria by inducing a cuproptosis‐like death pathway through intracellular Cu2+ accumulation and energy depletion.

Assessment of three Resistance-Nodulation-Cell Division drug efflux transporters of Burkholderia cenocepacia in intrinsic antibiotic resistance [PDF]

open access: yes, 2009
Burkholderia cenocepacia are opportunistic Gram-negative bacteria that can cause chronic pulmonary infections in patients with cystic fibrosis. These bacteria demonstrate a highlevel of intrinsic antibiotic resistance to most clinically useful ...

QSAR Studies on Bacterial Efflux Pump Inhibitors

open access: yes, 2015
Antimicrobial drug resistance occurs when bacteria undergo certain modifications to eliminate the effectiveness of drugs, chemicals, or other agents designed to cure infections. To date, the burden of resistance has remained one of the major clinical concerns as it renders prolonged and complicated treatments, thereby increasing the medical costs with ...

Targeting the Mapk13‐Tcf1‐Slc7a5 Axis via One‐Carbon Metabolic Regulation to Prevent Chronic Allograft Vasculopathy

open access: yesAdvanced Science, EarlyView.
This study emphasizes the role of the Mapk13‐Tcf1‐Slc7a5‐methionine metabolism axis in stem‐like CD4+ T cells. Moreover, it uncovers the mechanism through which limiting one‐carbon metabolism in CD4+ stem‐like T cells suppresses the tide of chronic allograft vasculopathy, offering potential targets to promote long‐term graft survival.

A Cascade Recognition of Activatable Probe for Fluorescence Navigation Glioblastoma Surgery: Overcoming Blood‐Brain Barrier and Off‐Target Limitations

open access: yesAdvanced Science, EarlyView.
A cascade recognition of activatable probe ANG‐hCy‐MC is used for high‐precision depiction of glioblastoma (GBM) margin. This probe crosses the blood‐brain barrier (BBB) through LRP1 receptor‐mediated transport and provides excellent fluorescence signal contrast between the tumor and normal tissues, thereby enabling ultra‐selective imaging and precise ...

Cascade Therapy of Periodontitis via Sequential Release of Ribosome‐Targeting Antimicrobial Peptide and Irisin From a Multifunctional MOF‐Based System

open access: yesAdvanced Science, EarlyView.
This study presents a novel strategy for periodontitis treatment by co‐delivering a membrane‐ and ribosome‐targeting antimicrobial peptide GF and Irisin through a pH‐responsive metal‐organic framework. The system enables sequential release, providing rapid antibacterial action, anti‐inflammatory and antioxidative effects, as well as promoting bone ...
