Gustducin - Gustducin in The Stomach

Gustducin in The Stomach

Recent work by Enrique Ronzengurt has shed some light on the presence of gustducin in the stomach and gastrointestinal tract. His work suggests that gustducin is present in these areas as a defense mechanism. It is widely known that some drugs and toxins can cause harm and even be lethal if ingested. It has already been theorized that multiple bitter taste reception pathways exist to prevent harmful substances from being ingested, but a person can choose to ignore the taste of a substance. Ronzegurt suggests that the presence of gustducin in epithelial cells in the stomach and gastrointestinal tract are indicative of another line of defense against ingested toxins. Whereas taste cells in the mouth are designed to compel a person to spit out a toxin, these stomach cells may act to force a person to spit up the toxins in the form of vomit.
