Cellular Biophysics: Bacterial Endospore, Membranes and Random Fluctuation [PDF]
Purposeful motion of biological processes can be driven by Brownian motion of macromolecular complexes with one-sided binding biasing movement in one direction: a Brownian ratchet, now proposed to explain membrane motion during a phagocytosis-like process in bacteria.

Systems biology of cellular membranes: a convergence with biophysics
Systems biology and systems medicine have played an important role in the last two decades in shaping our understanding of biological processes. While systems biology is synonymous with network maps and ‘‐omics’ approaches, it is not often associated with mechanical processes.

The boot-shaped respiratory complex I (CI) consists of a mitochondrial matrix and membrane domain organized into N-, Q- and P-modules. The N-module is the most distal part of the matrix domain, whereas the Q-module is situated between the N-module and ...

Cryo-EM structure of the potassium-chloride cotransporter KCC4 in lipid nanodiscs. [PDF]
Cation-chloride-cotransporters (CCCs) catalyze transport of Cl- with K+ and/or Na+across cellular membranes. CCCs play roles in cellular volume regulation, neural development and function, audition, regulation of blood pressure, and renal function.

FRET sensors reveal the retinal entry pathway in the G protein-coupled receptor rhodopsin
Summary: The photoreceptor rhodopsin (Rho) becomes active when a tethered inverse agonist ligand (11CR) is photoconverted to an agonist (ATR). The ligand-binding pocket of inactive rhodopsin is completely enclosed, whereas active rhodopsin displays pores

“Parking-garage” structures in nuclear astrophysics and cellular biophysics [PDF]
A striking shape was recently observed for the endoplasmic reticulum, a cellular organelle consisting of stacked sheets connected by helical ramps [Terasaki et al., Cell 154, 285 (2013)].

Biophysical Tools to Study Cellular Mechanotransduction [PDF]
The cell membrane is the interface that volumetrically isolates cellular components from the cell’s environment. Proteins embedded within and on the membrane have varied biological functions: reception of external biochemical signals, as membrane channels, amplification and regulation of chemical signals through secondary messenger molecules ...

Metabolomic profiling of ZrO2 nanoparticles in MC3T3‐E1 cells
The authors' previous study showed that zirconium oxide nanoparticles (ZrO2 NPs) induce toxic effects in MC3T3‐E1 cells; however, its toxicological mechanism is still unclear.

A perspective on cortical layering and layer-spanning neuronal elements [PDF]
This review article addresses the function of the layers of the cerebral cortex. We develop the perspective that cortical layering needs to be understood in terms of its functional anatomy, i.e., the terminations of synaptic inputs on distinct cellular ...
