5-HT3 receptor (HTR3A)
The serotonin receptor on the gut's vagus nerve endings and in the brainstem vomiting centre that chemotherapy triggers. Ondansetron and palonosetron block it, the foundation of modern anti-sickness treatment. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.
Biology
Ligand-gated ion channel for serotonin on vagal afferents and in the brainstem chemoreceptor trigger zone; blocked by setron antiemetics.
- Supportive care: prevention of chemotherapy-induced nausea and vomiting
