Kinesin and dynein use distinct mechanisms to bypass obstacles
Kinesin-1 and cytoplasmic dynein are microtubule (MT) motors that transport intracellular cargoes. It remains unclear how these motors move along MTs densely coated with obstacles of various sizes in the cytoplasm.

Abstract figure legend Schematic outlining the activation of hypoxia‐sensitive pathways, the influence of hypoxia and associated pathways on the cytoskeleton, and the impact of these on disease progression. Abstract A highly‐regulated and dynamic cytoskeleton is vital for functional cellular physiology and the maintenance of homeostasis.

A model for bidirectional traffic of cytoskeletal motors
We introduce a stochastic lattice gas model including two particle species and two parallel lanes. One lane with exclusion interaction and directed motion and the other lane without exclusion and unbiased diffusion, mimicking a micotubule filament and ...

Molecular Motors in Blood–Brain Barrier Maintenance by Astrocytes
The blood–brain barrier (BBB) comprises distinct cell types, including endothelial cells, pericytes, and astrocytes, and is essential for central nervous system (CNS) homeostasis by selectively regulating molecular transport and maintaining integrity. In

Abstract figure legend Regulatory mechanisms such as alternative splicing, post‐translational modification, membrane trafficking, and protein interactions control channel gating, membrane abundance, and overall activity of PIEZO2. Proper regulation supports PIEZO2‐dependent proprioceptive, somatosensory, nociceptive, pruriceptive and interoceptive ...

Robust and stable transcriptional repression in Giardia using CRISPRi. [PDF]
Giardia lamblia is a binucleate protistan parasite causing significant diarrheal disease worldwide. An inability to target Cas9 to both nuclei, combined with the lack of nonhomologous end joining and markers for positive selection, has stalled the ...

Fluctuation relations for molecular motors
This review is focused on the application of specific fluctuation relations, such as the Gallavotti-Cohen relation, to ratchet models of a molecular motor. A special emphasis is placed on two-states models such as the flashing ratchet model.

ABSTRACT Aim The alkali cation/proton exchanger NHE6/SLC9A6 regulates luminal pH homeostasis and trafficking of recycling endosomes in most tissues, especially neurons. Loss‐of‐function mutations in NHE6 cause Christianson Syndrome, an X‐linked neurodevelopmental and neurodegenerative disorder; however, the underlying molecular and cellular mechanisms ...

Engineered kinesin motor proteins amenable to small-molecule inhibition
The use of specific small molecule inhibitors can contribute to the study of kinesins' cellular functions. Here the authors develop a chemical-genetic approach to engineer kinesin motors that can be efficiently inhibited upon addition of cell-permeable ...

Unraveling the Dynamics of Oxytocin in Hypothalamic Neurons
Oxytocin (OT) plays an important role in regulating social behavior, and dysregulation of the oxytocinergic system leads to social impairments, such as autism spectrum disorder. Central OT release is poorly understood. Using live‐cell imaging to track vesicle trajectories, combined with machine learning‐based classification, the analysis reveals ...
