Two-Pore Domain Potassium Channels as Drug Targets: Anesthesia and Beyond.

, 2021
Two-pore domain potassium (K2P) channels stabilize the resting membrane potential of both excitable and nonexcitable cells and, as such, are important regulators of cell activity.

2D Co‐Assembly of Solid Acids Enables Stable Superprotonic Conduction Above 260°C

Advanced Functional Materials, EarlyView.
A two‐dimensional co‐assembly strategy integrates antimony phosphate and phosphotungstic acid nanosheets into free‐standing inorganic lamellar membranes with confined acid–acid interfaces. The resulting interfacial hydrogen‐bond network enables anhydrous proton conductivity exceeding 0.1 S cm−1 at 260°C and supports stable high‐temperature fuel‐cell ...

VKCDB: Voltage-gated potassium channel database

BMC Bioinformatics, 2004
Background The family of voltage-gated potassium channels comprises a functionally diverse group of membrane proteins. They help maintain and regulate the potassium ion-based component of the membrane potential and are thus central to many critical ...

Freeze‐Thaw Engineered Dual Conductivity Polymeric Binder Stabilizes Large‐Volume‐Change Lithium–Ion Battery Anodes

Advanced Functional Materials, EarlyView.
This work developed an all‐aqueous freeze‐thaw strategy to create a dual‐conductive PVA/P3KBT binder for high volume‐change lithium–ion battery anodes. The resulting binder system strengthens the electrode structure, supports ion and electron transport, and accommodates repeated volume changes, reducing cracking and improving long‐term cycling ...

Plectasin, First Animal Toxin-Like Fungal Defensin Blocking Potassium Channels through Recognizing Channel Pore Region

Toxins, 2015
The potassium channels were recently found to be inhibited by animal toxin-like human β-defensin 2 (hBD2), the first defensin blocker of potassium channels. Whether there are other defensin blockers from different organisms remains an open question. Here,

Engineered Nanotopography to Modulate Growth and Signaling of Neuronal Networks

Advanced Functional Materials, EarlyView.
This study examines the interaction between neurons and nanoscale topographies on engineered substrates. Neurons cultured on nanowires, nanopillars and nanoneedles exhibit enhanced neurite outgrowth, form more organized neuronal circuits, and display improved synaptic connectivity, compared to flat substrates.
