Sentences with phrase «calcium influx»
"Calcium influx" refers to the movement of calcium ions into a cell. These ions are necessary for various cellular functions, such as muscle contractions, nerve signaling, and enzyme activation. Full definition
A role for calcium influx in setting the threshold for CD4 + CD8 + thymocyte negative selection.

When stimulating release by calcium influx through channels, a difference between BoNT / C1 and TeNT emerged, which suggests that cleavage of synaptobrevin modifies the coupling between channels and release - competent vesicles.
Found that proteins bound to the cytoplasmic portion of one subtype of glutamate receptor, the N - methyl - D - aspartate receptor, play a critical role coupling local calcium influx through the channel to elicit adaptive gene transcription in neurons.
«In principle what we are doing is letting calcium influx into a cell remotely,» says Arnd Pralle, an assistant professor of physics at S.U.N.Y. Buffalo and a co-author of the Nature Nanotechnology study.
It was clear, however, that the extremely short time between calcium influx and neurotransmitter discharge would not permit assembly of a multi-protein machine.
Binds to voltage-gated calcium channels that are upregulated in response to a noxious insult to inhibit calcium influx, thereby inhibiting release of excitatory neurotransmitters
«If you think about biology, there are a lot of cell events that are triggered by calcium influx and subsequently make a cell secrete something or make a muscle twitch.»
In contrast, CX546 increases nerve cell activity and calcium influx into nerve cells by enhancing the activity of proteins called AMPA (α - amino -3-hydroxy-5-methyl-4-isoxazolepropionic acid) receptors.
Several years ago, when Feske and his colleagues were at another institution, they were the first to identify ORAI1, a new calcium channel, which is essential for calcium influx and T - cell function.
By introducing a calcium sensitive fluorescent substance in the neural tissue, it becomes possible to trace the calcium influx in neurons and thus visualize neural activity.
During an action potential, calcium influx into the presynaptic terminal triggers the fusion of synaptic vesicles with the plasma membrane, leading to the release of transmitter through the process of exocytosis.
When the researchers undertook the current study, it was not known whether progesterone interacted directly with CatSper to trigger the calcium influx, or acted on some other molecule (which, in turn, acted on CatSper).
