The phrase "acidic store" is correct and usable in written English.
It can be used in contexts related to chemistry, food, or environments that have a low pH level.
Example: "The acidic store in the laboratory contains various chemicals that require careful handling due to their corrosive nature."
Alternatives: "sour repository" or "tart storage".
To the best of our knowledge, TPEN has not been previously used to investigate NICR or indeed Ca2+ release from any acidic store.
For example, in atrial myocytes it has been proposed that NAADP evokes Ca 2+ release from an acidic store, which enhances general SR Ca 2+ release by increasing SR Ca 2+ load and activating RyR sites.
That TPCs are found on cytolytic granules agrees with the NAADP acidic store pharmacology because cytolytic granules are the acidic, secretory lysosomes of CTL and natural killer (NK) cells [ 25, 29].
In addition to acidic store alkalinization, it has been shown that fertilization of sea urchin eggs led to a change in cytosolic pH from 6.9 to 7.3 with a concomitant acidification of the sea water, and that the egg remains alkaline for approx. 60 min [ 48, 49].
The LRRK2-mediated effects involve activation of nicotinic acid adenine dinucleotide phosphate (NAADP -sensitive two-pore chaNAADP -sensitiveated on acidic stores, and channelslocked by a specific anTPCsnist.
Hence, lysosomes and other acidic stores, such as secretory granules, are referred to as small Ca2+ stores.
Acidic stores (e.g., endosomes, lysosomes, secretory granules and lysosome-related organelles) can also undergo regulated Ca2+ release (Morgan et al., 2011) (Fig. 1).
In this respect, the vesicular nature of acidic stores may be an important determinant of outcome.
In acidic stores inhibition of either pair of RyR1/3 or TPC1/2 abolished responses.
Moreover, activation of the ADP-ribosyl cyclase CD38 was also required to initiate the release of Ca2+ from acidic stores.
This suggests that Ca2+ release from acidic stores by NAADP is a crucial permissive factor for exocytosis.
