Advanced Functional Materials, EarlyView.Synthetic cells are engineered herein to respond to an external chemical messenger by the activation of intracellular catalysis. The chemical messenger molecules are catalytically generated by an extracellular enzyme or a mineral surface, whereas the intracellular catalysis emerges via direct enzyme activation or via protein refolding.

Differential Compartmentalization of Enzymatic Reactions for Lactate Signaling Across Protocells
Advanced Functional Materials, EarlyView.Two populations of protocells consisting of giant unilamellar vesicles containing active species and distinct artificial organelles are competent of collective behavior by mimicking production, intercellular communication, and detection of the bioinspired signal molecule lactate. Enzymatic cascade reactions within artificial organelles demonstrate that

Modeling the Contributions of the Exocytotic Machinery and Receptor Desensitization to Short- and Long-Term Plasticity of Synapses Between Neocortical Pyramidal Neurons [PDF]
, 2001 Short-term synaptic depression (STD) refers to the progressive decrease in synaptic efficacy during a spike train. This decrease may be explained in terms of presynaptic and postsynaptic processes, such as a decrease in the probability of transmitter ...

Cooperative protein transport in cellular organelles
, 2011 Compartmentalization into biochemically distinct organelles constantly exchanging material is one of the hallmarks of eukaryotic cells. In the most naive picture of inter-organelle transport driven by concentration gradients, concentration differences ...

The SNARE Protein Syntaxin 3 Confers Specificity for Polarized Axonal Trafficking in Neurons. [PDF]
, 2016 Cell polarity and precise subcellular protein localization are pivotal to neuronal function. The SNARE machinery underlies intracellular membrane fusion events, but its role in neuronal polarity and selective protein targeting remain unclear.

Advanced Functional Materials, EarlyView.The pre‐internalization phase of endocytosis remains poorly characterized at single‐cell levels. Single‐cell pre‐internalization mechanics are investigated using advanced robotic techniques. Cancer cells exhibit biphasic adhesion – rapid initial binding followed by reinforcement – while fibroblasts show gradual engagement.

The presynaptic ribbon maintains vesicle populations at the hair cell afferent fiber synapse [PDF]
, 2018 The ribbon is the structural hallmark of cochlear inner hair cell (IHC) afferent synapses, yet its role in information transfer to spiral ganglion neurons (SGNs) remains unclear.

Annexin A2 promotes phagophore assembly by enhancing Atg16L+ vesicle biogenesis and homotypic fusion
Nature Communications, 2015 Plasma membrane budding of Atg-16L-positive vesicles represents a very early event in the generation of the phagophore and in the process of macroautophagy. Here we show that the membrane curvature-inducing protein annexin A2 contributes to the formation
