Table 4.

Semiquantitative evaluation of the density of CB2R, GPR55, TRPV1, and TRPA1 immunoreactivity in different cellular elements of the skin of dogs with atopic dermatitis (AD-dogs).

Receptors Mast cells (tryptase) Macrophages and dendritic cells (IBA1) T-cells (CD3) Neutrophils (CAL)
CB2R ++ +++ + NA
GPR55 +++ ++ +++ ++
TRPV1 ++ ++ +
TRPA1 ++ + ++

C, cytoplasmic; M, membrane; NA, not applied. Immunoreactive cells were graded as: –, negative; +, faint; ++, moderate; +++, bright.
