A turquoise fluorescence lifetime-based biosensor for quantitative imaging of intracellular calcium
Nature Communications, 2021 Currently, genetically encoded calcium indicators are not suitable for direct quantification. Here the authors engineer a fluorescence lifetime imaging calcium biosensor, Turquoise Calcium Fluorescence LIfeTime Sensor (Tq-Ca-FLITS), and measure ...

Calcium Imaging in Neuron Cell Death [PDF]
, 2014 Intracellular Ca2+ is involved in control of a large variety of cell functions including apoptosis and neuron cell death. For example, intracellular Ca2+ overload is critical in neuron cell death induced by excitotoxicity. Thus, single cell monitoring of intracellular Ca2+ concentration ([Ca2+]cyt ) in neurons concurrently with apoptosis and neuron ...

Dendritic spike saturation of endogenous calcium buffer and induction of postsynaptic cerebellar LTP. [PDF]
PLoS ONE, 2008 The architecture of parallel fiber axons contacting cerebellar Purkinje neurons retains spatial information over long distances. Parallel fiber synapses can trigger local dendritic calcium spikes, but whether and how this calcium signal leads to plastic ...

Calcium imaging in the optical stretcher
Optics Express, 2011 The Microfluidic Optical Stretcher (MOS) has previously been shown to be a versatile tool to measure mechanical properties of single suspended cells. In this study we combine optical stretching and fluorescent calcium imaging. A cell line transfected with a heat sensitive cation channel was used as a model system to show the versatility of the setup ...

eLife, 2020 The ‘building-block’ model of inositol trisphosphate (IP3)-mediated Ca2+ liberation posits that cell-wide cytosolic Ca2+ signals arise through coordinated activation of localized Ca2+ puffs generated by stationary clusters of IP3 receptors (IP3Rs). Here,

CaPTure: Calcium PeakToolbox for analysis of in vitro calcium imaging data
BMC Neuroscience, 2022 Background Calcium imaging is a powerful technique for recording cellular activity across large populations of neurons. However, analysis methods capable of single-cell resolution in cultured neurons, especially for cultures derived from human induced ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Immune effector cell‐associated hemophagocytic lymphohistiocytosis‐like syndrome (IEC‐HS) is a life‐threatening hyperinflammatory toxicity distinct from cytokine release syndrome (CRS) and neurotoxicity following chimeric antigen receptor T‐cell (CAR‐T) therapy. In a single‐institution retrospective cohort of pediatric and young adult patients
