Sentences with phrase «ion channel into»

To get around this problem, neurobiologists Susana Lima and Gero Miesenböck of the Yale University School of Medicine in New Haven, Connecticut, inserted a gene that codes for a rat ion channel into Drosophila fruit flies.
The therapy employs a virus to insert a gene for a common ion channel into normally blind cells of the retina that survive after the light - responsive rod and cone photoreceptor cells die as a result of diseases such as retinitis pigmentosa.
They also inserted the light - sensitive ion channels into a different set of neurons in the medulla: glutamatergic neurons, which release the neurotransmitter glutamate.

Not exact matches

Bound to the cell membrane, Na ± K+ATP ase uses the energy of adenosine triphosphate (ATP) molecules to pump sodium out of the cell and potassium into the cell, maintaining a charge gradient that allows ions to flow through open channels.
It is controlled, in part, by a series of channels on the surface of heart cells that regulate the movement of different ions into and out of the cells.
(Ion channels are passages through a cell's membrane that allow charged particles, or ions, into or out of the cell.)

Motor rotation is powered by proton flow into the cell via ion channels.
In mammals, proteins called ion channels embedded in the cell membrane translate temperature information into electrical signals that activate nerve cells.

Such ion channels are often involved in transmitting signals into cells.
Whereas in the nematode experiment the researchers targeted nanoparticles to temperature - sensitive ion channels that naturally exist in the membranes of the worms» nerve cells, the scientists inserted the gene for a heat - activated ion channel called TRPV1 into the human and rat cells.
The channels allow charged atoms and molecules to travel into or out of cells; the extra channels enabled ions to cross more easily, thereby reducing how polarized these cells had become.
The SCN5A protein winds through the membrane of heart muscle cells, forming a channel that opens to let sodium ions flow into the cells.
Like a type of door, sodium channels allow sodium ions to flow into nerve cells through tiny pores.
When light is shone on the neuron, the channel opens up and allows electrical ions to flow into the cell; a bit like a battery being charged by a solar cell.
In the system, nanoparticles injected into the brain convert a gentle, external magnetic field into heat, which triggers heat - sensitive ion channels that have been genetically engineered into neurons.
Together, these findings have brought into focus the central role of ion - conducting channels in sustaining normal cellular function and enabled fine - grained analysis of conditions in which the channels go awry.
