"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. (nature.com)
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. (science.sciencemag.org)
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. (gladstone.org)
