Exploration for calcium requirements in carbachol-induced pigment granule dispersion To test whether an elevation in intracellular Ca 2+ was required for carbachol-induced pigment granule dispersion, RPE cells were isolated, treated with forskolin (FSK) and then challenged to disperse in the presence or absence of the merane-permeant Ca 2+ chelator BAPTA-AM.

Activation of muscarinic receptors increases the activity of …

Abstract Acetylcholine modulates the function of the cochlear nucleus via several pathways. In this study, the effects of cholinergic stimulation were studied on the cytoplasmic Ca 2+ concentration of granule neurones of the rat dorsal cochlear nucleus (DCN). Ca 2+ transients were recorded in Oregon-Green-BAPTA 1-loaded brain slices using a calcium imaging technique.

Synchronous calcium oscillations in cerebellar granule …

The concentration of cytosolic Ca2+ ([Ca2+]) was monitored in cerebellar granule cell cultures by digital imaging of fura-2 loaded cells. In the presence of Mg2+, cells grown in low K+ cultures responded to N-methyl-d-aspartate (NMDA) with uniform increases in [Ca2+] from a stable basal [Ca2+].

Other major interests of the group are the mechanisms of the input integration in granule cells (#5 published in 2016, #6 2013). To directly measure the propagation of signals along the dendritic arbors of granule cells we employ dendritic recordings, optical stimulation and calcium imaging, and verifiion of the obtained data by multicompartmental modelling.

Expression and Function of the Calcium-Sensing …

Renin is the critical enzyme in the formation of the potent vasoconstrictor angiotensin II. Renin is produced by, stored in, and released from juxtaglomerular (JG) cells, which are loed in the lamina media of the afferent arteriole at the entrance to the glomerulus. 1 Renin secretion is controlled through a variety of regulatory pathways, 2 but all act through the second messenger cAMP, 3

Synaptic sodium spikes trigger long‐lasting …

Using two‐photon imaging in acute rat brain slices, we demonstrate that this prolonged electrical response is paralleled by an unusual, long‐lasting postsynaptic calcium signal. We find that this slow synaptic Ca 2+ signal requires sequential activation of NMDA receptors, a nonselective ion conductance I CAN and T‐type voltage‐dependent Ca 2+ channels.

In vivo deep two‐photon imaging of neural circuits with …

2012) was used to record Ca 2+ transients in dentate gyrus granule cells approximately 800 μm below the hippocampal surface (Pilz et al . 2016 ). To express R‐CaMP1.07, a Cre‐dependent adeno associated virus was injected into the dentate gyrus of transgenic mice expressing Cre‐recoinase in granule cells.
