The retrograde inhibition of IPSCs in rat cerebellar purkinje cells is highly sensitive to intracellular Ca2+.

, 2000
The Ca2+-dependent retrograde inhibition of inhibitory postsynaptic currents (depolarization-induced-suppression of inhibition; DSI) was investigated using fura-2 Ca2+ measurements and whole-cell patch-clamp recordings in rat cerebellar Purkinje cells ...

Floral biology and propagation of blue-flowered Conospermum spp

, 2003
Blue-flowered Conospermum are endemic to Western Australia, and show great potential as cut flowers. Propagation from cuttings or seed proved difficult, and root initiation in vitro is problematic. This thesis examines the floral biology of the species

Stabilization of the cortical cytoskeleton by the lipid raft-associated protein cap23 [PDF]

, 2006
In the present work, we identified the lipid raft-associated protein Cap23 to be involved in several important neuronal functions like the organization of lipid raft platforms, the maturation and stabilization of the actin- and intermediate filament ...

Expression and Localization of Caveolin-1, and the Presence of Membrane Rafts, in Mouse and Guinea Pig Spermatozoa

, 2001
In somatic cells, caveolin-1 plays several roles in membrane dynamics, including organization of detergent-insoluble lipid rafts, trafficking of cholesterol, and anchoring of signaling molecules.

Extrasynaptic Release of Dopamine in a Retinal Neuron Activity Dependence and Transmitter Modulation

, 2001
Extrasynaptic release of dopamine is well documented, but its relation to the physiological activity of the neuron is unclear. Here we show that in absence of presynaptic active zones, solitary cell bodies of retinal dopaminergic neurons release by ...

Expression and Function of Complexin 1 in Mammalian Sperm Acrosomal Exocytosis

, 2005
Membrane-bound vesicle fusion is important for a wide variety of cellular events including exocytosis. Exocytosis is regulated by the SNARE complex, whose core includes three proteins.

Gray matter NG2 cells display multiple Ca2+-signaling pathways and highly motile processes

, 2011
NG2 cells, the fourth type of glia in the mammalian CNS, receive synaptic input from neurons. The function of this innervation is unknown yet. Postsynaptic changes in intracellular Ca2+-concentration ([Ca2+]i) might be a possible consequence. We employed

Probabilistic secretion of quanta and the synaptosecretosome hypothesis: evoked release at active zones of varicosities, boutons, and endplates

, 1997
A quantum of transmitter may be released upon the arrival of a nerve impulse if the influx of calcium ions through a nearby voltage-dependent calcium channel is sufficient to activate the vesicle-associated calcium sensor protein that triggers exocytosis.
