<unk>  are aggregates formed by a small number of chemoreceptor cells with characteristics similar to those found in the taste cells of the oropharyngeal cavity. The<unk>  are similar to the taste buds but are smaller, resembling the developing taste buds.<unk>  are located in the larynx distally to the portion in which are present laryngeal taste buds and proximally to the region in which solitary<unk>  cells are found. Rarely,<unk>  may be found in the distal portion of the airway. The elements forming the<unk>  share common morphological and biochemical characteristics with the taste cells located in taste buds of the oropharyngeal cavity. In particular, they may express molecules of the chemoreceptorial cascade (e.g. trans-membrane taste receptors, the G-protein gustducin, PLCbeta2, IP3R3, TRPM5). Usually, in<unk> a true "taste pore" is lacking. To date, the functional role of the<unk>  is unknown.
