Intracellular Ca2+ signals provide astrocytes with a specific form of excitability that enables them to regulate synaptic transmission. In this study, we demonstrate that NAADP-AM, a membrane-permeant analogue of the new second messenger nicotinic acid-adenine dinucleotide phosphate (NAADP), mobilizes Ca2+ in astrocytes and that the response is blocked by Ned-19, an antagonist of NAADP signalling.

6 p, 836.2 KB The presence of a high-Km hexokinase activity in dog, but not in boar, sperm. / Fernández Novell, Josep M. (Universitat de Barcelona.

The presence of a high-Km hexokinase activity was tested in both dog and boar spermatozoa. Hexokinase kinetics from dog extracts showed the presence of a specific activity (dog-sperm glucokinase-like protein, DSGLP), in the range of glucose concentrations of 4–10 mM, whereas boar sperm did not show any DSGLP activity.
