5-HT3 receptor

The 5-HT3 receptor is a specific type of protein found on certain nerve cells in the body, especially in the brain and gastrointestinal system. It responds to serotonin, a chemical involved in mood, nausea, and digestion. When serotonin binds to this receptor, it can influence feelings, vomiting, and gut movements. Medications targeting the 5-HT3 receptor, called antagonists, are often used to prevent nausea and vomiting, especially in cancer treatments. Overall, this receptor plays a key role in regulating both emotional states and digestive functions.
