[Larynx] Chemical (T2R ligands) and ontogenetic activation of these cells triggered cough-like expulsive reflexes, establishing them as the sensory end organ for the cough reflex to chemical insults—6/9

[Hypopharynx] Single-cell transcriptomics revealed taste bud cells expressing T2Rs—GPCRs for noxious substances. T2R ligand and ontogenetic activation of them triggered swallowing, establishing them as the sensory end organ for swallowing reflexes to chemical insults—4/9
