Treatment of mice with 8-methoxypsoralen plus longwave UV radiation (UVA, 320-400 nm) decreased their response to contact sensitizers applied subsequently to unirradiated skin. This decreased reactivity exhibited a delayed time course, it affected the afferent but not the efferent phase of the reaction, and it was associated with the development of splenic suppressor cells. These suppressor cells were antigen-specific T lymphocytes, and they prevented the induction, but not the elicitation, of contact hypersensitivity in recipient mice. In all of these characteristics, the decreased reactivity induced by treatment with psoralen plus UVA radiation (PUVA) resembled that produced by UV radiation of shorter wavelengths (less than 320 nm). These studies suggest that PUVA treatment may initiate the same sequence of cellular events as does exposure to sunlamp (UVB, 280-320 nm) radiation, leading to preferential activation of the suppressor cell pathway.
