tuft cell of auditory tube
tuft cell of auditory tube
A tuft cell that is part of the epithelium of the pharyngotympanic (auditory) tube. This chemosensory cell is often positioned near cholinoreceptive sensory nerve fibers, suggesting a role in neuroimmune communication. It detects chemical signals and releases neuropeptides, such as acetylcholine (ACh) and CGRP, which contribute to inflammatory responses that help protect deeper tissues from harmful substances.
