... familial Alzheimer's disease disrupt the flow of calcium ions within neurons. The two proteins ... notes Foskett. "However, our experiments have identified calcium inside cells as the important feature. No ...
... -term memory formation in honeybees is instigated by a calcium ion cascade. Researchers writing in the open ... modulation of calcium during learning affects long-term memory specifically while leaving ...
... of intracellular activities by binding and releasing other proteins. Calmodulin can bind up to four calcium ions, and the three-dimensional spatial structure of calmodulin varies with the number of ...
... period, you get a huge response," says Nicholas Smith, who led the research. The laser pulses cause the release of calcium ions within the cells, Smith explains, and this action ...
... to trigger cartilage growth, but they think it helps calcium ions enter a cell, and calcium is known to play an integral role in growing cartilage.
The team plans to test the ...
... form bone matrix and rapid mineralisation of bone nodules. It is the release of soluble silica and calcium ions in specific concentrations that activate the genes. Gene activation occurs only when the ...
... rhythmically and coincides with similarly regular variations in another stimulant messenger, the calcium ion, resulting in pulsatile secretion of insulin.
Optimal glucose-induced insulin secretion ...
... in the membrane, how the peptide aggregates affect or influence calcium channels (portals for calcium ion movement) in the membrane, and how the peptides interact with membranes constructed with other ...

Calcium ions play an essential role in transmitting signals ... also should look at how amyloid-beta causes calcium overload and whether removing plaques really ...
... manage to appropriately sense and respond to the variety of calcium fluctuations within cells. Reporting in the June 27 ... levels. "Once a local calcium ion sticks to the C lobe, it seldom lets go, and ...
... protein called SERCA. Normally, muscle contraction initiates following the release of a wave of calcium ions from a compartment called the sarcoplasmic reticulum (SR); SERCA then actively pumps the ...
... cells. For example, when naive T-cells are primed for an immune response, the concentration of calcium ion in their cytoplasm jumps up. So when the cytoplasm contains a dye that fluoresces when it ...
... as a complex of numerous interconnected protein subunits. Two of these subunits react to the binding of calcium ions to the complex: the yellow-fluorescent protein (YFP) lights up and the illuminating ...
... converted into a chemical signal via release of a hormone or neurotransmitter.
The trigger for this is the flux of calcium ions into the nerve terminal. The receiving neuron on the other site of the ...
... found that the myosin Vb (five-b) molecule in hippocampal neurons responded to a flow of calcium ions from the synaptic space by popping up and into action. One end of the myosin is attached the ...
