Spatiotemporal Control Over Protein Release from Artificial Cells via a Light‐Activatable Protease

Advanced Biology, Volume 9, Issue 5, May 2025.
Stimulus‐responsive protein release is essential for intercellular communication. Mimicking this functionality in artificial cells is promising to study the working principles of cellular signaling. Herein, an engineered light‐activatable protease is implemented in a coacervate‐based artificial cell platform to establish user‐defined spatiotemporal ...

Recent advances in mathematical modeling and statistical analysis of exocytosis in endocrine cells [PDF]

, 2016
open5noMost endocrine cells secrete hormones as a result of Ca(2+)-regulated exocytosis, i.e., fusion of the membranes of hormone-containing secretory granules with the cell membrane, which allows the hormone molecules to escape to the extracellular ...

Spatiotemporal Regulation of Synaptic Vesicle Fusion Sites in Central Synapses [PDF]

Neuron, 2017
The number and availability of vesicle release sites at the synaptic active zone (AZ) are critical factors governing neurotransmitter release; yet, these fundamental synaptic parameters have remained undetermined. Moreover, how neural activity regulates the spatiotemporal properties of the release sites within individual central synapses is unknown ...

Light‐Triggered Protease‐Mediated Release of Actin‐Bound Cargo from Synthetic Cells

Advanced Biology, Volume 9, Issue 5, May 2025.
TEV Prtoease‐mediated Releasable Actin‐binding Protein (TRAP) is a protein‐based platform consisting of a cargo tightly bound to reconstituted actin networks in synthetic cells which can be proteolyticly released from the bound actin, followed by its secretion through membrane translocation mediated by a cell‐penetrating peptide.

Demand Forecasting in Bike-sharing Systems Based on A Multiple Spatiotemporal Fusion Network [PDF]

arXiv, 2020
Bike-sharing systems (BSSs) have become increasingly popular around the globe and have attracted a wide range of research interests. In this paper, the demand forecasting problem in BSSs is studied. Spatial and temporal features are critical for demand forecasting in BSSs, but it is challenging to extract spatiotemporal dynamics.

Accelerate Spatiotemporal Fusion For Large-Scale Applications

International Journal of Applied Earth Observation and Geoinformation
Spatiotemporal fusion (STF) can provide dense satellite image series with high spatial resolution. However, most spatiotemporal fusion approaches are time-consuming, which seriously limits their applicability in large-scale areas. To address this problem, some efforts have been paid for accelerating STF approaches with help of graphics processing units
