Palytoxin-group toxins (PlTX) exert their potent biological activity by altering mechanisms of
ion homeostasis in excitable and non-excitable tissues. This review will describe major …

Palytoxin is a marine toxin first isolated from zoanthids (genus Palythoa), even though
dinoflagellates of the genus Ostreopsis are the most probable origin of the toxin. Ostreopsis …

Background and purpose: Dinoflagellates from the genus Ostreopsis have been related to
the production of palytoxin and analogues. Based on that, this paper describes functional …

To elucidate the mechanism of palytoxin (PTX)-induced Na+ influx, we examined the effect
of amiloride, an inhibitor of Na+ H+-antiporter, on PTX-induced Na+ influx into cultured …

Synapses are specialised structures where interneuronal communication takes place. Not
only brain function is absolutely dependent on synaptic activity, but also most of our organs …

Palytoxin (PTX) is a potent marine toxin that causies serious damage to various tissues and
organs. It has been reported to affect the transport of cations across the plasma membranes …

The effect of palytoxin (PTX), a potent marine toxin, on catecholamine (CA) secretion from
cultured bovine adrenal chromaffin cells was examined. PTX at concentrations of over 10 …

Palytoxin has been long associated to the ingestion of contaminated food in tropical coastal
areas. In the last years, however, the increasing number of reports of poisonings among …

The effect of ouabain on palytoxin (PTX)-induced catecholamine secretion from cultured
bovine adrenal chromaffin cells was examined in relation to its effect on calcium (Ca 2+) …

The effects of the tetrodotoxin-insensitive Na+ channel activator palytoxin on both the
secretion of endogenous catecholamines and the formation of 14C-catecholamines from …
