Contact dermatitis is a common skin disease caused by contact with irritants or allergens. Irritant contact dermatitis is a result of nonspecific irritant factors, which cause activation of mainly innate immunity, resulting in skin inflammation. Contact hypersensitivity, which manifests itself as allergic contact dermatitis, is result of adaptive immune response, where sensitization to hapten-carrier complexes leads to T-cell-mediated contact allergy. Subsequent contact with the hapten results in skin inflammation. This review concentrates on the role of cutaneous receptors in contact dermatitis and highlights potential targets for treatment interventions.
