Intracellular calcium elevation induced by extracellular application of cyclic-ADP-ribose or oxytocin is temperature-sensitive in rodent NG108-15 neuronal cells with or without exogenous expression of human oxytocin receptors.


ADP-ribosyl cyclase and/or CD38 are activated after oxytocin receptor stimulation in the hypothalamus and pituitary in adult mice, leading to facilitation of oxytocin secretion. Although cyclic adenosine 5'-diphosphoribose (cADPR) primarily acts as an intracellular second messenger, it has been suggested that extracellular cADPR stimulates intracellular… (More)
