Graphical representation of the immunoreactive cell counts: the kappe olfactory neurons (Kappe ON), microvillous olfactory neurons (Microvillous ON), crypt olfactory neurons (Crypt ON), one-ciliated olfactory neurons (One-ciliated ON), and multi-ciliated olfactory neurons (Multi-ciliated ON) in the olfactory epithelium labeled by Piezo 1, Piezo 2, and Calretinin; the light cells, dark cells, Merkel-like cells, and supporting cells of the taste buds immunolabeled by Piezo 1, Piezo 2, and Calretinin; and the isolated chemosensory cells marked by Piezo 2. The statistical analysis showed different expression patterns for the investigated proteins in the different cellular subpopulations. N°, mean of the cells immunopositive to Piezo 1, Piezo 2, and Calretinin. The lowercase letters indicate the statistical significance between the different cell subpopulations, with p < 0.05.
