title: MTSEA potentiates 5-HT3 receptors containing the nicotinic alpha4 subunit.
abstract: In order to study the subunit composition of 5-HT3 receptors (5-HT3R), we report that (2-aminoethyl)methanethiosulfonate (MTSEA) can enhance the function of both nicotinic ACh receptors (nAChRs) comprised of alpha4/beta2 subunits, and heteromeric channels assembled from serotonin 5-HT3R and alpha4 nAChR subunits. MTSEA has no effect on homomeric 5-HT3 receptor channels.
