Cytokines in skin lesions of psoriasis

Cytokine levels were compared in aqueous extracts of stratum corneum from psoriatic lesions and normal heel. Samples from heel contained high levels of interleukin-1α (IL-1α) and β measured in immunoassays, although only the IL-1α was biologically active. No other cytokines could be detected in heel...

description Cytokine levels were compared in aqueous extracts of stratum corneum from psoriatic lesions and normal heel. Samples from heel contained high levels of interleukin-1α (IL-1α) and β measured in immunoassays, although only the IL-1α was biologically active. No other cytokines could be detected in heel samples. Interleukin-1 (IL-1) levels were dramatically reduced in lesional samples. A neutrophil chemoattractant was found in all lesional extracts, and was demonstrated to be mainly interleukin-8 (IL-8) using a specific neutralizing antiserum. Tumor necrosis factor α (TNF-α) and β (TNF-α), and interferon α (IFN-α) and γ (IFN-γ) were detected in lesional extracts using immunoassays, however, no equivalent biological activities could be detected. Interleukins 2 (IL-2), 4 (IL-4), and 6 (IL-6), granulocyte and granulocyte/macrophage colony stimulating factor (GM-CSF), could not be detected in any samples. IL-8 is therefore the only biologically active cytokine shown in this study to be elevated in psoriatic lesional extracts, and may therefore play a role in the pathogenesis of the disease.
