An enterotoxin is a protein toxin released by a micro-organism in the lower Intestine. Enterotoxins are frequently cytotoxic and kill cells by altering the permeability of the epithelial cells of the intestinal wall. They are mostly pore forming toxins, secreted by bacteria, that assemble to form pores in cell membranes. This causes the cells to die.
A neurotoxin is a toxin that acts specifically on nerve cells – neurons– usually by interacting with membrane proteins such as ion channels.
