Cholesterol and synaptic vesicle exocytosis [PDF]
Communicative & Integrative Biology, 2010 LIPIDS MAY AFFECT SYNAPTIC FUNCTION IN AT LEAST TWO WAYS: by acting as ligands for effector proteins [e.g., phosphatidylinositol (4,5) bisphosphate, diacylglycerol-mediated signaling] or by modifying the physicochemical properties and molecular organization of synaptic membranes.

Short term synaptic depression imposes a frequency dependent filter on synaptic information transfer. [PDF]
PLoS Computational Biology, 2012 Depletion of synaptic neurotransmitter vesicles induces a form of short term depression in synapses throughout the nervous system. This plasticity affects how synapses filter presynaptic spike trains. The filtering properties of short term depression are

FEBS Letters, EarlyView.In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

Autophagy in cancer and protein conformational disorders
FEBS Letters, EarlyView.Autophagy plays a crucial role in numerous biological processes, including protein and organelle quality control, development, immunity, and metabolism. Hence, dysregulation or mutations in autophagy‐related genes have been implicated in a wide range of human diseases.

Quantitative Analysis Linking Inner Hair Cell Voltage Changes and Postsynaptic Conductance Change: A Modelling Study [PDF]
, 2015 This paper presents a computational model which estimates the postsynaptic conductance change of mammalian Type I afferent peripheral process when airborne acoustic waves impact on the tympanic membrane. A model of the human auditory periphery is used to

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 ...

Ambient but not local lactate underlies neuronal tolerance to prolonged glucose deprivation [PDF]
, 2018 Neurons require a nearly constant supply of ATP. Glucose is the predominant source of brain ATP, but the direct effects of prolonged glucose deprivation on neuronal viability and function remain unclear.
