The taste receptor cells (TRCs), called Type I, II, III, and IV, have been identified and characterized [, From the taste TRCs, taste information converges to the nucleus of the solitary tract (NTS) through the branch of the facial nerve (chorda tympani), the glossopharyngeal nerve, and the vagus nerve [, Several mechanisms, alone or in concert, are hypothesized to be involved in COVID-19-induced anosmia/dysosmia [, Another hypothesis is linked to the olfactory epithelium disruption following COVID-19 infection.
