Mean data ± standard deviation (∆σ) of the immunoreactive cells counts for the following: kappe neurons, microvillous cells, one-ciliated cells, and multi-ciliated cells of the olfactory epithelium detected by Piezo 1, Piezo 2, and Calretinin. The statistical analysis showed different expression patterns for the investigated proteins in the different cellular subpopulations. Mean values ± standard deviation, Δσ; -, no immunoreactivity detected.
