Photochemotherapy employing 8-methoxypsoralen and ultraviolet radiation (PUVA) is widely used in the treatment of psoriasis. The photoactivation of psoralens in skin cells leads to DNA photoadduct formation which may be responsible for the efficacy of PUVA. Subsequent mutations may lead

Multimodality biological response-modifier therapy that includes photopheresis, interferon, and bexarotene is the standard of care in our institution for advanced cutaneous T-cell lymphoma with peripheral blood involvement. We added psoralen plus long-wave UV-A (PUVA) to this regimen in 5 patients

Photo(chemo)therapy is widely used to treat psoriasis, the pathogenesis of which might be caused by an imbalance of Th17 cells/regulatory T cells (Treg). In the present study, we evaluated the effects of photo(chemo)therapy on the Th17/Treg balance and Treg function.

Photosensitization reactions involve phototoxic reactions and photoallergic reactions, which are less common. Common drugs and chemicals that photosensitize humans are listed. Phototoxic reactions include the following: 1) direct photosensitization (type I reactions), in which the reactions of the triplet-state sensitizer

The observation that long tracts of RNA are associated with replicating molecules of mitochondrial DNA (mtDNA) suggests that the mitochondrial genome of mammals is copied by an unorthodox mechanism. Here we show that these RNA-containing species are present in living
