Induction of contact hypersensitivity in the mouse model.

Contact hypersensitivity (CHS) in the mouse model is a standard method to assess delayed type hypersensitivity (DTH) responses in the skin induced by low molecular weight chemicals that in humans cause contact dermatitis. These responses are clinically important and present as eczematous skin reactions. Here, this chapter describes the standard protocol for T cell-mediated CHS and a variation thereof, which allows to address more specific questions regarding immunologic pathomechanisms.
