Figure 6

Photomicrographs of cryosections of canine skin showing transient receptor potential ankyrin 1 (TRPA1) immunoreactivity (IR) in the tissues of the healthy dogs (CTRL) (a–c) and in the dogs with atopic dermatitis (AD) (d–f). (a–c) The white arrows indicate some DAPI-labeled nuclei of the keratinocytes of the CTRL dogs showing moderate cytoplasmic TRPV1-IR. The TRPA1 immunolabelling was brighter in the more superficial cells. The open arrows indicate some DAPI-labeled nuclei of the dermal cells showing moderate TRPV1-IR. (d–f) The white arrows indicate some DAPI-labeled nuclei of the keratinocytes of the AD dogs showing bright cytoplasmic TRPV1-IR. Not all the cells of the suprabasal layer showed the same degree of TRPA1-IR which was brighter in the cytoplasm of the more superficial cells. The open arrows indicate some DAPI-labeled nuclei of the dermal cells showing bright TRPA1-IR. Bar, 50 μm.
