Programmable Paracrine‐Mimetic Microneedle System for Temporal Regulation of Cardiac Repair

Advanced Science, EarlyView.
Temporal signaling is encoded into a programmable paracrine‐mimetic microneedle patch via tris(2,2'‐bipyridyl)dichlororuthenium(II) hexahydrate/sodium persulfate‐tuned hydrogel microparticles that deliver TGF‐β, IGF‐1, and VEGF over phase‐matched 7‐, 14‐, and 28‐day windows.

Effects of efflux pumps on antifungal activity of chitosan against Candida albicans

Journal of Oral Microbiology
Background Antifungal resistance is a major problem, commonly caused by drug-efflux pump overexpression. To evaluate if chitosan could be effective in drug-resistant Candida infections, we investigated the effects of efflux pumps on antifungal activity ...

Tailored Covalent Organic Frameworks Enable the Encapsulation of Living Cells to Produce Rare Ginsenoside

Advanced Science, EarlyView.
This work reports the in situ fabrication of Escherichia coli@covalent organic frameworks (E. coli@COFs) in phosphate‐buffered saline. The COFs form an exoskeleton on E. coli, protecting intracellular β‐glucosidase (Ssbgl) while enhancing mass transfer.

Convergence of Plasmid‐Mediated tmexCD‐toprJ With Critical Resistance Genes Fuels Spread of Multidrug Resistant Bacteria

Advanced Science, EarlyView.
Global dissemination of tmexCD‐toprJ across bacterial hosts and ecological niches is accompanied by its convergence with blaKPC, blaNDM, and mcr on mobile plasmids. Recombination and acquisition of resistance modules generate distinct multidrug resistant plasmid architectures, facilitating the emergence and spread of high‐risk bacterial populations ...

Exploring allosteric efflux pump inhibitors and the role of bacterial membrane potential in modulating drug resistance

Frontiers in Microbiology
Multi-drug resistance (MDR) bacteria pose a significant global health challenge, primarily driven by the activity of multi-drug efflux pumps and their intimate coupling to bacterial membrane bioenergetics.

An Intravesical Akkermansia muciniphila‐Based Chemo‐Immunotherapeutic Platform for Bladder Cancer

Advanced Science, EarlyView.
Pasteurized Akkermansia muciniphila is engineered into an intravesical F127/doxorubicin platform that couples localized chemotherapy with immune remodeling. By inducing apoptosis, ferroptosis, and immunogenic cell death, this chemo‐immunotherapeutic system enhances dendritic‐cell maturation, antigen cross‐presentation, and tumor‐specific CD8+ T‐cell ...

Dynamics associated with the efflux pumps in biofilms and persister cells of Cryptococcus neoformans and Cryptococcus gattii

Microbiology Spectrum
Cryptococcosis is a systemic mycosis affecting immunocompromised individuals (mainly C. neoformans) and immunocompetent hosts (mainly C. gattii). Effective treatment remains challenging due to antifungal resistance, driven by efflux pumps, target enzyme ...

Mycobacterium tuberculosis efflux pumps: an update

, 2013
The selection and diffusion of Mycobacterium tuberculosis multidrug-resistant (MDR-TB), extensively drug-resistant (XDR-TB) and, more recently, totally drug-resistant (TDR) strains constitute a serious threat for tuberculosis global control. Mycobacteria,

Active efflux systems in the solvent-tolerant bacterium Pseudomonas putida S12 [PDF]

, 2002
The aim of the research presented in this thesis was to study the molecular mechanisms of organic solvent tolerance in Pseudomonas putida S12. This bacterium is capable of growth at saturated solvent concentrations, which are lethal to normal bacteria ...

Biochemistry of Bacterial Multidrug Efflux Pumps

, 2012
Bacterial pathogens that are multi-drug resistant compromise the effectiveness of treatment when they are the causative agents of infectious disease. These multi-drug resistance mechanisms allow bacteria to survive in the presence of clinically useful ...
