Palytoxin (PTX), isolated from the marine soft coral Palythoa tuberculosa, increases the
cation conductance of human red cell membranes. In the presence of 10 (-10) M PTX and 10 …

Palytoxin (PTX), a potent toxin isolated from the marine soft coral Palythoa tuberculosa
increases the cationic permeability of red cell membranes and inhibits the (Na+, K+) …

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 …

Background and purpose: Palytoxin (PLT) is a potent toxin that binds to the Na, K‐ATPase.
Palytoxin is highly neurotoxic and increases the cytosolic calcium concentration ([Ca2+] c) …

Palytoxin (PTX), a highly toxic and sugar‐containing substance isolated from Palythoa
tuberculosa, caused K+ release from rabbit red blood cells. Cardiac glycosides, such as …

1. Palytoxin is one of the most potent toxins known so far. It acts as an haemolysin and alters
the functioning of excitable cells. 2. A primary action of palytoxin in excitable cells is to …

Palytoxin-induced whole-cell and single channel currents were recorded in mouse
neuroblastoma cells. Palytoxin-induced single channel currents had a slope conductance of …

Palytoxin (PTX) causes a depolarization in every excitable tissue tested. We examined
whether PTX induces a channel current, which might be responsible for the depolarizing …

Palytoxin (PTX) caused K+ release from rabbit erythrocytes which was dependent on the
concentrations of extracellular Ca 2+ and PTX. In a Ca 2+-free solution, PTX still caused a …

The effects of palytoxin (PTX) on transmembrane potentials and currents of frog skeletal
muscle were analyzed by intracellular microelectrode techniques and the double sucrose …
