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

open access: yesAdvanced 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.

Comparison of bacterial intracellular and secreted proteins produced in milk versus medium for Escherichia coli by proteomic analysis

open access: yesJournal of Dairy Science
: The growth and reproduction of microorganisms are dependent on nutrient supply. Here, milk and Luria-Bertani (LB) media were used as nutrition sources for Escherichia coli, and the changes in bacterial and secretory proteins at 3 time points (3, 9, and

The Assembly of Beta-Barrel Proteins into Bacterial Outer Membranes [PDF]

open access: yesBiophysical Journal, 2017
In order to cause disease, bacterial pathogens must (i) avoid immune detection, (ii) inhibit immune responses, and (iii) induce pathology favoring bacterial replication. In gram-negative bacteria, pathogenesis depend on structures assembled in the bacterial outer membrane.

Domain organization of long autotransporter signal sequences [PDF]

open access: yes, 2010
Bacterial autotransporters represent a diverse family of proteins that autonomously translocate across the inner membrane of Gram-negative bacteria via the Sec complex and across the outer bacterial membrane.

Transport of proteins into mitochondria [PDF]

open access: yes, 1985
Translocational intermediates of precursor proteins of ATPase F1β subunit and cytochrome c1 across mitochondrial membranes were analyzed using two different approaches, transport at low temperature and transport after binding of precursor proteins to ...

Dual‐Targeting Biomimetic Nanozymes Loaded Microneedle Patch Promotes Scarless Wound Healing Through Anti‐Inflammatory and Anti‐Fibrotic Effects

open access: yesAdvanced Science, EarlyView.
This study developed a dual‐targeting biomimetic nanozyme hybrid system (Cu‐CeO2@ABs‐FTP) and integrated it with HAMA hydrogel to fabricate a microneedle patch (CAF@MN). The patch promotes fibroblast‐mediated wound repair, targets macrophages to induce M2 polarization, and targets myofibroblasts to exert anti‐fibrotic effects, thereby enabling rapid ...

Drought Stress Mediated Changes in Food Crops: Mechanisms and Remediation Strategies

open access: yesAdvanced Science, EarlyView.
This work presents a multi‐scale framework for flavonoid‐mediated drought tolerance in staple food crops, integrating ROS redox regulation, antioxidant defense, rhizosphere microbial interactions, and sustainable agronomic practices. This interdisciplinary model provides core insights to develop climate‐resilient cropping systems and enhance global ...

The density of Braun's Lipoprotein determines vesicle production in E. coli.

open access: yesPLoS ONE
Production of extracellular vesicles by Gram-negative bacteria is known to be associated with blebbing of the outer membrane. Several proteins within Gram-negative bacteria crosslink the outer membrane to the cell wall, and thereby stabilize the cell ...

Cryo-EM structure of the QseG-QseE complex reveals an accessory protein-driven two-component system activation mechanism

open access: yesmBio
The two-component system (TCS) enables bacteria to sense and respond to environmental changes through histidine kinase-mediated signaling cascades. Although the core components of TCSs have been extensively studied, the molecular basis of accessory ...

Disease‐Stage Synchronized Nanozyme Therapy for Polymicrobial Sepsis through Adaptive Catalytic and Immune Reprogramming

open access: yesAdvanced Science, EarlyView.
A disease‐stage synchronized nanozyme platform is developed to treat polymicrobial sepsis by adapting its functions to changing infection environments. The system eliminates multidrug‐resistant bacteria during early infection while reducing inflammation and restoring immune balance during recovery, providing an integrated strategy for infection control
