Fig. 2: Local RAAS impairment leads to loss of taste and smell during COVID-19.
From: Does the RAAS play a role in loss of taste and smell during COVID-19 infections?
A. Hypothesis schematic representation: Local RAAS in nasal and oral tissue drives loss of taste and smell after SARS-CoV-2 infection due to reduced protease activity. B Colocalization of APN (CD13) and gustducin. Confocal microscopy image of tongue shows co-localization of APN and gustducin.
