Effects of opioid peptides and morphine on histamine‐induced catecholamine secretion from cultured, bovine adrenal chromaffin cells

Abstract: IThe effect of opioid peptides and morphine on histamine-induced catecholamine secretion has been studied in monolayer cultures of dispersed, bovine adrenal chromaffin cells. 2 Histamine-induced a dose-dependent secretion of both adrenaline and noradrenaline with a threshold dose of approximately 5 nM, an EC50 of 150 nM and maximal secretion at 10 AM. 3 Catecholamine secretion induced by I tM histamine was completely dependent on extracellular calcium, was inhibited in a dose-dependent manner by mepyramine (I … Show more

“…The response to histamine was also partially reduced by the H -antagonist, mepyramine, at 1 m (Figure 2a), a concentration that fully antagonized the H,-receptor effects on catecholamine release and inositol phosphate production in these cells (Livett & Marley, 1986;Wan et al, 1989a). A combination of both mepyramine and cimetidine each at 1 AM, however, completely blocked the cyclic AMP response to histamine.…”

“…In contrast, several classes of H1 binding site have been found in other tissues, including adrenal cortex (Chang et al, 1979). Hl-receptors increase cytosolic Ca2" in isolated chromaffin cells (Staudermann & Pruss, 1990) and they have been known for over 70 years to induce catecholamine secretion (Elliott, 1912;Szczygielski, 1932; see Livett & Marley, 1986). This secretory action is fully dependent on extracellular Ca2" (Poisner & Douglas, 1966;Livett & Marley, 1986;Noble et al, 1988).…”

“…The specificity of NSTX for the nicotinic receptorionophore complex was tested by studying its effects on catecholamine release evoked by K+, which activates voltage-dependent Ca"+ channels directly by depolarizing the chromaffin cell membrane, to bring about exocytosis (Douglas, 1975) and histamine, which evokes release via H,-receptors (Livett & Marley, 1986). NSTX had no effect on either K+-induced or histamine-induced catecholamine release, demonstrating the high specificity of the toxin for the nicotinic response.…”

“…These channels are regulating the nicotinic and muscarinic secretory response of cat and bovine chromaffin cells [90][91][92]. While ER Ca 2+ release by histamine causes a mild and transient catecholamine release response [93], a more sustained application causes a longer effect [93][94][95]. This greater effect could be explained by the fact histamine-elicited [Ca 2+ ] c elevations has two components: an initial transient phase due to ER Ca 2+ release and a late more sustained phase due to Ca 2+ entry [30,83,96,97].…”
