Local postsynaptic voltage-gated sodium channel …

Neuronal dendritic spines have been speculated to function as independent computational units, yet evidence for active electrical computation in spines is scarce. Here we show that strictly local voltage-gated sodium channel (Na v) activation can occur during excitatory postsynaptic potentials in the spines of olfactory bulb granule cells, which we mimic and detect via coined two-photon

19/5/2014· Migration of astrocytoma cells is associated with intracellular calcium oscillations The above results prompted us to further analyze the role of Ca 2+ in migration. To do so, we used confocal imaging of intracellular Ca 2+ in single migrating cells. In the presence of

Live-cell Imaging Techniques | Learn & Share | Leica …

Live-cell imaging allows investigation of dynamical processes of living cells instead of giving a “snapshot” of a cell’s current state - it turns snapshots into movies. Live-cell imaging provides spatial and temporal information of dynamic events in single cells, cellular networks ( in situ ) or even whole organisms ( in vivo ).

Differentiation impairs low pH-induced Ca2+ signaling …

Hence, the ability of human granule cells to respond to extracellular acidifiion by generating Ca(2+) signals and ERK activation is state-dependent, being lost upon differentiation. Differentiation impairs low pH-induced Ca2+ signaling and ERK phosphorylation in granule precursor tumour cells.
