Mechanism of systemic immune suppression by UV irradiation in vivo. II. The UV effects on number and morphology of epidermal Langerhans cells and the UV-induced suppression of contact hypersensitivity have different wavelength dependencies.

Abstract

We previously reported that broad band UV radiation or narrow bands of UV (Hbw 3 nm) of wavelengths 250 to 320 nm cause a systemic suppression of cont
